OPINION FILED: July 29, 2014

Appeal from the Labor and Industrial Relations Commission

Before Division Two: Gary D. Witt, Presiding Judge, Lisa White Hardwick, Judge and 

Alok Ahuja, Judge

Randolph County appeals the Labor and Industrial Relations Commission's final 

award of workers' compensation benefits to its former employee, Tammy MooreRansdell ("Moore-Ransdell"). Randolph County contends the Commission erred in 

concluding that Moore-Ransdell suffered a compensable injury because: (1) the injury 

came from a hazard or risk to which she was equally exposed in her normal 

nonemployment life; and (2) the accident at work was merely a triggering or precipitating 

factor and not the prevailing factor in causing her resulting medical condition and 
2

disability. Because the Commission's determinations were supported by competent and 

substantial evidence and were not against the weight of the evidence, we affirm. 

FACTUAL AND PROCEDURAL HISTORY

Moore-Ransdell, age fifty at the time of the accident, worked for Randolph County 

for ten years. As a "deeds clerk" in the Assessor's office, Moore-Ransdell worked with 

"property records cards," which were stored in filing cabinets. Her medical record as 

explained through her History and Physical at Boone Hospital Center indicates that she 

was "well with regard to her low back and lower extremities until Tuesday, February 26, 

2008." 

On that day, Moore-Ransdell was updating the property records cards. One of the 

file folders she needed was in the back of the bottom file drawer, which she described as 

"extremely full" and "jammed up." Because of defects in the filing system and the 

location of the file cabinet, Moore-Ransdell had to squat down and twist to remove a file 

from the tightly jammed bottom file drawer. She squatted down, reached into the back of 

the file drawer, and twisted her body as she tried to remove the file. She immediately 

experienced extreme pain in her low back. She could barely stand up and had difficulty 

walking. Moore-Ransdell finished working the rest of the day but had too much low 

back pain the following day to get out of bed. 

On March 1, 2008, Moore-Ransdell spoke to her supervisor about her injury. Her 

supervisor referred her to Kevin D. Komes, M.D., an orthopedic surgeon, for evaluation 

of her back pain for workers' compensation purposes. The record indicates that Moore-
3

Ransdell told Dr. Komes that she had low back pain, pain in her buttocks, and numbness 

in her entire left leg, all of which began immediately after the file cabinet incident. 

In April 2008, Moore-Ransdell filed a claim for workers' compensation benefits. 

Randolph County denied her claim and refused to authorize further medical treatment. 

Moore-Ransdell then sought medical treatment on her own. Her primary care 

physician referred her to Thomas R. Highland, M.D. Dr. Highland is a board-certified 

orthopedic surgeon and professor who had been in practice for fifteen years as of the time 

of the hearing. He specializes "in the treatment of the spine, including cervical, thoracic, 

and lumbar spine." In examining Moore-Ransdell, Dr. Highland noted that she had 

diminished sensation in her left leg, buttock and back pain on the left, right leg pain, and 

tenderness in her low back. He initially referred her for physical therapy and pain 

management. She participated in physical therapy and received epidural steroid 

injections, nerve root injections, and facet blocks, but the pain worsened. 

In July 2008, Moore-Ransdell underwent a lumbar discogram, which is a test that 

places a needle into the disc itself and injects a dye. According to Dr. Highland, the 

discogram showed degeneration in the discs at L3-4, L4-5, and L5-S1, which are the 

bottom three discs in the back. The discogram reproduced the pain that Moore-Ransdell 

had been having in her low back and down her leg. Dr. Highland recommended a threelevel fusion of the discs. Moore-Ransdell did not have surgery at that time but attempted 

a more conservative treatment plan of further therapy, continued steroid injections and 

pain medication. Despite the additional pain management, she was unable to tolerate the 

pain.
4

In August 2010, Moore-Ransdell returned to Dr. Highland and reported that the

steroid injections had given her only short-term relief and that she was still having back 

pain and numbness and tingling in her left leg. She was having difficulty living with the 

pain. Dr. Highland took an x-ray and noted that the three problematic discs had gotten 

worse, particularly at the L5-S1 level. An MRI showed further degeneration at L3-4 and 

L4-5, inflammatory changes at L5-S1, increasing bulging of the L3-4 disc, and increasing 

compression of the nerves at that level. In examining Moore-Ransdell, Dr. Highland 

noted that she was experiencing more loss of sensation in her left leg than she had in 

2008 and that she had a slight weakness to the dorsiflexion of the left foot, which she did 

not have in 2008.1 

Dr. Highland again recommended that Moore-Ransdell undergo surgery to treat 

her injury. In October 2010, he wrote in a letter that Moore-Ransdell had "continuing 

degeneration of all three segments in her back which were the source of her pain." He 

stated, "I clearly feel that her continuing symptoms and her need for surgery are directly 

related to the work injury in February 2008." He stated that his impression of MooreRansdell's condition was: "(1) Acute lumbar strain in February 2008; (2) Internal disc 

disruption to L3-4, L4-5 and L-5-S1 secondary to work injury in February 2008; (3) Need 

for anterior lumbar fusion L3-4, L4-5 and L5-S1 secondary to work injury in February 

2008." 

In November 2010, Moore-Ransdell underwent anterior fusion surgery. MooreRansdell's back and leg pain improved post surgery.

 

1Dr. Highland explained that "dorsiflexion" is the act of raising one's toes toward the ceiling. 
5

On October 29, 2012, a hearing was held before an Administrative Law Judge 

(ALJ) on Moore-Ransdell's workers' compensation claim. During the hearing, MooreRansdell testified regarding the February 26, 2008 accident, the pain she felt afterwards, 

the treatment she received, and her condition after the anterior fusion surgery. Presently, 

she is unable to sit comfortably for more than forty-five to fifty minutes and to stand for 

more than thirty to forty minutes without having increasing pain in her low back and 

difficulty walking. She is prescribed Vicodin for pain, medication for nerve pain, muscle 

relaxers, and Cymbalta for depression. 

In addition to her testimony and medical records, Moore-Ransdell offered Dr. 

Highland's deposition testimony and disability rating report. On direct examination, Dr. 

Highland testified in part:

Q. All right. Let me ask you a hypothetical question, Doctor. If you 

would assume that the history that Ms. Ransdell gave you when you first 

saw her was true and correct, that is, that she had back pain and leg pain 

after squatting down to get a file – something out of a file cabinet and 

twisting, and that she did that on about February 26th, 2008. And then you 

saw her – at the times that you saw her, do you have an opinion based on 

reasonable medical certainty as to whether or not that incident caused the 

conditions that you found when you examined her?

A. Yes. 

Q. What is your opinion?

A. That the injury caused the condition that I treated her for.

Q. Okay. All right. And do you have an opinion as to whether or not 

that injury that she described is what necessitated this course of treatment 

and surgery that you have now performed?

A. Yes.
6

Q. And what is that opinion?

A. That it caused the injury and the problem for which we eventually 

did do the surgery.

Q. All right. And in your opinion, the surgery that was performed, was 

that the appropriate medical procedure to take in Ms. Ransdell['s] case?

A. Yes. 

On cross-examination, Dr. Highland agreed with defense counsel that MooreRansdell had a degenerative back before the February 26, 2008 accident. He also agreed 

that aging and normal activities of daily living can cause such degenerative problems to 

progress over time. Dr. Highland testified that, when he re-evaluated Moore-Ransdell in 

August 2010, he found that she had increasing stenosis and continuing degeneration of 

the three discs, which were the source of her pain. He agreed that, without her preexisting disc degeneration, the lumbar strain she suffered at work on February 26, 2008, 

would not have necessarily required the three-level fusion procedure that he performed. 

Dr. Highland explained that the lumbar strain was an "injury to the muscles and 

ligaments, which is usually a more short-term issue" and that "the continued pain was 

from the deteriorating discs that she had" (emphasis added). Dr. Highland answered 

affirmatively when asked whether the work accident "triggered a pain from the 

underlying discs" and when asked whether he had to "address the underlying condition to 

address that pain." 

Dr. Highland also was asked on cross-examination about the factors that 

contributed to Moore-Ransdell's medical condition. Dr. Highland testified that one factor 
7

was the underlying disc degenerative process, one was "possibly" her smoking, and the 

third was lumbar strain from the incident at work. Dr. Highland reiterated his medical 

opinion that "in this patient," the lumbar strain "was the primary factor" of the overall 

condition. Dr. Highland also testified that the workplace incident caused the 

degeneration of the spine to "become symptomatic." 

On redirect examination, Dr. Highland was asked two questions:

Q. Your testimony before – the prevailing cause, I think, is the term 

we use now, of this condition that she had when she came to see you, 

that’s caused by this squatting down and twisting. Would that be your 

opinion?

A. Yes.

Q. All right. Would that be based on reasonable medical certainty?

A. Yes.

(Emphases added.)

Dr. Highland determined that she reached maximum medical improvement in 

November 2011 and that she should be permanently restricted from lifting over ten 

pounds, frequent bending, prolonged sitting, and prolonged standing. Dr. Highland 

opined that Moore-Ransdell was twenty-five percent permanently and partially disabled 

as a result of the February 2008 work injury.

At the hearing, Randolph County offered the deposition testimony and reports of 

Michael C. Chabot, D.O., an orthopedic spine surgeon who performed a medical 

evaluation on Moore-Ransdell in October 2008 on behalf of Randolph County. Dr. 

Chabot diagnosed Moore-Ransdell with back pain and a history of back strain. 
8

The ALJ found that Moore-Ransdell sustained her burden of proof that the 

February 26, 2008 work-related accident caused her low back pain, subsequent surgery, 

and related medical treatment. Specifically, the ALJ found credible Moore-Ransdell's 

testimony regarding how the accident occurred and the immediate and intense low back 

pain that resulted. The ALJ also cited Dr. Highland's opinion that the February 26, 2008 

accident caused Moore-Ransdell's low back condition and need for treatment, including 

surgery. The ALJ examined the content of Dr. Chabot's analysis and stated that she 

found Dr. Highland's testimony more persuasive than Dr. Chabot's. 

The ALJ determined that Randolph County was liable to Moore-Ransdell for 

medical expenses in the amount of $130,574.00, temporary total disability benefits for 

100 weeks, and permanent partial disability benefits based upon twenty-five percent

disability to the body as a whole.2 Randolph County filed an application for review with 

the Commission. The Commission issued a final award affirming and incorporating the 

ALJ's findings and decision. Randolph County appeals.3

STANDARD OF REVIEW

This court will not disturb the award in a workers' compensation case unless the 

Commission acted in excess of its powers, the award was procured by fraud, the facts 

found by the Commission do not support the award, or there was not sufficient competent 

 

2Moore-Ransdell had also sought payment for future medical expenses. The Commission found that she 

failed to sustain her burden of proof with regard to her need for future medical treatment. Moore-Ransdell does not 

appeal this finding. 

3Moore-Ransdell asks us to dismiss both of Randolph County's points on appeal because of briefing 

deficiencies. While we have discretion to dismiss an appeal based upon briefing deficiencies, we usually do not 

exercise such discretion "unless the deficiency impedes disposition on the merits." Maskill v. Cummins, 397 S.W.3d 

27, 31 (Mo. App. 2013) (internal quotation marks and citation omitted). This is because we prefer to decide a case

on its merits. Id. Despite its deficiencies, we are able to ascertain Randolph County's arguments from its brief; 

therefore, we elect to review Randolph County's claims to provide a determination on the merits.

evidence in the record to support the award. § 287.495.1.4 We review questions of law 

de novo. Tillotson v. St. Joseph Med. Ctr., 347 S.W.3d 511, 516 (Mo. App. W.D. 2011)

(citation omitted). In deciding whether there is sufficient competent and substantial 

evidence to support the Commission's award, we examine the evidence in the context of 

the whole record. Hampton v. Big Boy Steel Erection, 121 S.W.3d 220, 222-23 (Mo. 

banc 2003). We recognize that the Commission was free to believe or disbelieve any 

evidence, and we defer to the Commission's credibility determinations. Clark v. Harts 

Auto Repair, 274 S.W.3d 612, 617 (Mo. App. W.D. 2009) (citation omitted). As the 

claimant, Moore-Ransdell bore the burden of proving all essential elements of her 

workers' compensation claim. Bond v. Site Line Surveying, 322 S.W.3d 165, 170 (Mo. 

App. W.D. 2010) (citation omitted).

ANALYSIS

Randolph County's two points on appeal allege error in the Commission's finding 

that Moore-Ransdell suffered a compensable injury. Section 287.020 governs the 

determination as to whether an employee has sustained a compensable injury from a 

work-related accident. Tillotson, 347 S.W.3d at 517. Section 287.020.2 defines an 

accident for workers' compensation purposes:

The word "accident" as used in this chapter shall mean an 

unexpected traumatic event or unusual strain identifiable by time and place 

of occurrence and producing at the time objective symptoms of an injury 

caused by a specific event during a single work shift. An injury is not 

compensable because work was a triggering or precipitating factor.

 

4All statutory references are to the Revised Statutes of Missouri 2000 as currently supplemented, unless 

otherwise indicated.
10

Section 287.020.3(1) requires that the injury must have "arisen out of and in the 

course of employment." For an injury by accident to be compensable, the accident must 

be "the prevailing factor in causing both the resulting medical condition and disability." 

Id. "The prevailing factor" is the "primary factor, in relation to any other factor, causing 

both the resulting medical condition and disability." Id. Section 287.020.3(2) further 

provides that an injury is deemed to arise out of and in the course of employment only if:

(a) It is reasonably apparent, upon consideration of all the 

circumstances, that the accident is the prevailing factor in causing the 

injury; and

(b) It does not come from a hazard or risk unrelated to the 

employment to which workers would have been equally exposed outside of 

and unrelated to the employment in normal nonemployment life.

These provisions are to be strictly construed, and the Commission is to weigh the 

evidence "impartially without giving the benefit of the doubt to any party." § 287.800. 

Point One

Randolph County contends in its first point that the Commission acted in excess of 

its authority in compensating Moore-Ransdell because her injury did not arise out of her 

employment, in that her injury came from a hazard or risk to which she was equally 

exposed in normal nonemployment life. Specifically, Randolph County argues that the 

risk was simply the act of bending over, which was not unique to Moore-Ransdell's job 

and was nothing more than a risk of everyday life to which she was equally exposed in 

her normal nonemployment life.

For an injury to arise out of employment under Section 287.020.3(2)(b), there 

must be "a causal connection between the injury at issue and the employee's work 
11

activity." Johme v. St. John's Mercy Healthcare, 366 S.W.3d 504, 510 (Mo. banc 2012). 

A causal connection does not exist if the injury "merely happened to occur while working 

but work was not a prevailing factor" and the risk involved was one to which the worker 

would have been equally exposed in normal nonemployment life. Miller v. Mo. Highway 

& Transp. Comm'n, 287 S.W.3d 671, 674 (Mo. banc 2009). The injury must have 

occurred because the risk was due to some condition of the worker's employment. Id. In 

other words, the employee must have been injured because she was at work and not 

simply while she was at work. Pope v. Gateway to West Harley Davidson, 404 S.W.3d 

315, 320 (Mo. App. E.D. 2012).

Applying these principles, the Supreme Court in Miller found that an employee 

whose knee popped while he was walking briskly on an even road surface to retrieve 

materials needed for his job as a road crew worker failed to prove a causal connection 

between his work activity and his injury. Id. at 672-74. The court noted that the injurycausing risk -- walking -- was one to which the employee would have been equally 

exposed in normal nonemployment life and that "[n]othing about work" caused the 

employee's knee to pop. Id. at 674. Thus, the court determined that, while the 

employee's injury may have arisen during the course of his employment because it 

occurred while he was at work, it did not arise out of his employment under Section 

287.020.3(2)(b). Id. 

Similarly, in Johme, 366 S.W.3d 504, the Supreme Court determined that an 

employee who was injured in an office kitchen while making coffee when she turned and 

twisted her ankle, which caused her foot to fall off her high-heeled shoe, failed to show a 
12

causal connection between her work and her injury. The court noted that "the evidence 

did not link her act of making coffee as the cause of her injury and fall," and the only 

connection her turning, twisting her ankle, and falling off her shoe had to her work 

activity was that it occurred while she was at work. Id. at 511. Because the employee's 

risk of injury from turning, twisting her ankle, and falling off her shoe was a risk to 

which she would have been equally exposed in her normal nonemployment life, the court 

held that, under section 287.020.3(2)(b), her injury was not compensable. Id. at 511-12.

Randolph County argues that, like the risk of injury from the employee's walking 

in Miller and from the employee's turning, twisting her ankle, and falling off her shoe in 

Johme, the risk of injury from Moore-Ransdell's bending over was one to which she was 

equally exposed outside of work. Randolph County mischaracterizes the risk in this case. 

The evidence shows that Moore-Ransdell did not suffer the low back injury after merely 

"bending over" at her place of employment. Rather, she credibly testified that, in 

attempting to perform her work activity of updating property cards, she squatted down to 

pull out a lower file drawer that was "extremely full," reached into the back of the file 

drawer, and twisted to remove the file from the tightly packed drawer. In doing so, she 

experienced immediate extreme pain in her lower back.

Unlike in Miller and Johme, the evidence here specifically linked MooreRansdell's work activity as the cause of her low back injury. She was required to update 

property cards as one of her primary job duties. Due to Randolph County's storing the 

property cards in full file drawers, Moore-Ransdell had to squat down, reach into the 

back of a file drawer, and twist to remove the file containing the property card that she 
13

needed to update. Moore-Ransdell injured her back because she was at work, not merely 

while she was at work. See Pope, 404 S.W.3d at 320. Her risk of injury from squatting 

down, reaching into the back of a file drawer, and twisting to remove files from full file 

drawers was a risk to which she would not have been equally exposed in her normal 

nonemployment life. 

Point One is denied.

Point Two

In Point Two, Randolph County contends that the Commission's determination 

that Moore-Ransdell suffered a compensable injury was not supported by competent and 

substantial evidence and was against the weight of the evidence because the medical 

evidence showed that her work-related accident was merely a triggering or precipitating 

factor and not the prevailing factor in causing her medical condition and disability. 

"Medical causation, which is not within common knowledge or experience, must 

be established by scientific or medical evidence showing the relationship between the 

complained of condition and the asserted cause." Bond, 322 S.W.3d at 170 (internal 

quotation marks and citations omitted). See also T.H. v. Sonic Drive In of High Ridge, 

388 S.W.3d 585, 591 (Mo. App. E.D. 2012) (affirming Commission's determination in 

light of the standard of review that medical testimony was sufficient competent evidence 

of medical causation where that testimony and claimant's testimony supported 

determination that sexual assault was prevailing factor in stress and depression); Johnson 

v. Indiana W. Exp. Inc., 281 S.W.3d 885, 892 (Mo. App. S.D. 2009) ("When the right to 

compensation depends on the acceptance of one of two competing medical theories, the 
14

issue is one of fact and the commission's finding will not be disturbed unless the 

commission acted unreasonably in accepting testimony that was not substantial or 

decided the issue contrary to the overwhelming weight of the evidence."). The weight 

ascribed to a medical expert's opinion is a matter within the Commission's discretion. 

Bond, 322 S.W.3d at 170 (citation omitted). "[W]here the right to compensation depends 

on which of two medical theories should be accepted, the issue is peculiarly for the 

Commission's determination." Id. (internal quotation marks and citations omitted). 

Moreover, "[i]n determining compensability and disability, where inconsistent or 

conflicting medical opinions exist, objective medical findings shall prevail over 

subjective medical findings. Objective medical findings are those findings demonstrable 

on physical examination or by appropriate tests or diagnostic procedures." 

§ 287.190.6(2). However, "[d]eterminations with regard to causation . . . are questions of 

fact to be ruled upon by the Commission, and the reviewing court may not substitute its 

judgment on the weight of the evidence or on the credibility of witnesses for that of the 

Commission." Spencer v. Sac Osage Elec. Co-op. Inc., 302 S.W.3d 792, 800 (Mo. App. 

W.D. 2010). 

In this case, the Commission relied upon Dr. Highland's testimony that the work 

accident caused Moore-Ransdell's low back condition and need for treatment, including 

surgery. While the Commission noted Dr. Chabot's conflicting opinion as to causation, it 

expressly found Dr. Highland's testimony more persuasive than Dr. Chabot's. It was the 

Commission's prerogative to discount Dr. Chabot's testimony in favor of Dr. Highland's, 
15

and we defer to its decision in that respect. Hornbeck v. Spectra Painting, Inc., 370 

S.W.3d 624, 632 (Mo. banc 2012); Bond, 322 S.W.3d at 169.

5

 

The issue, then, is whether Dr. Highland's testimony, when examined in the 

context of the whole record as the Supreme Court prescribed in Hampton, constituted 

competent and substantial evidence to support the Commission's determination that the 

injury Moore-Ransdell suffered in the work accident was the primary factor in causing 

her low back condition and permanent partial disability. As the Commission noted in its 

award, Dr. Highland testified that the February 26, 2008 accident "caused the condition 

that [he] treated her for"; necessitated the course of treatment that he provided, including 

the anterior fusion surgery; was "the primary factor" that contributed to "[t]he overall 

condition of her lumbar spine"; and was the "prevailing cause" . . . "of this condition that 

she had when she came to see [him]."

The record contains sufficient competent evidence to support the Commission's 

determination that Moore-Ransdell's workplace accident was the "prevailing" or 

"primary" factor that caused her injuries. § 287.020.3(1) (As noted above, "[t]he 

prevailing factor'" is defined to be the primary factor, in relation to any other factor, 

causing both the resulting medical condition and disability.") To begin, the medical 

history indicates that Moore-Ransdell was "well" before her injury as to "her low back 

and lower extremities" and that her problems were new as of her first visit to Dr. Komes 

soon after the work injury. Additionally, the Commission expressly found that Moore-

 

5Randolph County also asserts that the Commission erred in finding that Moore-Ransdell testified credibly 

about the onset and extent of her low back pain. Again, we defer to the Commission's credibility determinations. 

Clark, 274 S.W.3d at 617. 
16

Ransdell "testified credibly to the squatting and twisting necessitated in pulling a file out 

of a low, full file drawer in the course of her employment for the Randolph County 

assessor's office and the immediate and intense low back pain resulting from that injury." 

Further, the Commission also expressly determined that Dr. Highland was "more 

persuasive" than Dr. Chabot, and the Commission stated that it based its award on the 

testimony of Moore-Ransdell and Dr. Highland. The Commission therefore found 

credible Dr. Highland's testimony that the lumbar strain from Moore-Ransdell's 

workplace accident "was the primary factor" in her overall condition. Smoking was 

another "possible" factor, but the workplace injury was the prevailing medical cause of 

her condition. Finally, the question presented is whether the workplace accident was the 

prevailing factor in Moore-Ransdell's injury, not whether the compensable injury is the 

prevailing factor in her overall resultant medical treatment. Tillotson, 347 S.W.3d at 518.

As noted above, Dr. Highland's key diagnoses were these: "(1) Acute lumbar 

strain in February 2008; (2) Internal disc disruption L3-4, L4-5 and L5-S1 secondary to 

work injury in February 2008; (3) Status post anterior and posterior fusion L3-4, L4-5 

and L5-S1 secondary to work injury in February 2008." Dr. Highland's testimony 

explains the diagnoses of the lumbar strain as well as the two conditions related to the 

discs, both of which are secondary to the work injury. Dr. Highland maintained 

throughout his care of Moore-Ransdell that her continuing symptoms and need for 

surgery were due to the work injury. His board-certified medical opinion was that the 

secondary diagnoses were not merely precipitated by that work accident, but rather that 

the squatting down and twisting resulted in lumbar strain that "was the primary factor" of 
17

the overall condition. Hence, Dr. Highland's testimony and diagnoses, once found 

credible by the Commission, leave little room to question the foundation of the 

Commission's decision. As noted above, "determinations with regard to causation . . . are 

questions of fact to be ruled upon by the Commission, and the reviewing court may not 

substitute its judgment on the weight of the evidence or on the credibility of witnesses for 

that of the Commission." Spencer, 302 S.W.3d at 800 (citation omitted). The 

Commission weighed competing medical explanations regarding the causation of MooreRansdell's injury and rejected the theory posited by Dr. Chabot. 

In reaching the opposite conclusion, the Dissent attempts to characterize the 

degenerative disc issues as apparently inevitable in spite of the workplace strain or that 

the disability determination is based only on the continuing pain Moore-Ransdell suffers 

rather than on the workplace injury. That analysis simply does not bear out upon a full 

review of Dr. Highland's expert testimony, the sole expert deemed persuasive. Certainly 

there was evidence from which the Commission could have determined that the 

workplace injury merely "triggered" or "precipitated" the condition rather than being the 

"primary" or "prevailing" factor.6 In any event, however, our standard of review renders 

that hypothetical determination moot under these facts. Our job is to review the record to 

determine whether there is sufficient competent evidence to support the decision of the 

 

6

In fact, as the Dissent points out, Dr. Highland responded affirmatively when defense counsel asked him 

whether it was his opinion that the "incident then triggered a pain from the underlying discs." Defense counsel 

asked several questions using the term "trigger." While it is true that "but for" causation alone is not sufficient to 

establish compensability under the Act because a claimant must establish that the injury was the "prevailing factor," 

see Dissenting Opinion at n.3, an action can be the "but for" cause of a medical condition or the "trigger" of a 

medical condition and also be the "prevailing factor," even though as a matter of law neither the "but for" cause nor 

a "trigger" alone mandates coverage under the Act. Additionally, Dr. Highland's testimony establishes necessary 

medical treatment "as may reasonably be required after the injury," which is a lower standard than the prevailing 

factor threshold. Tillotson, 347 S.W.3d at 518; § 287.140.1.
18

Commission, not to search through the record to see whether there is any evidence which, 

if found credible, may undermine the Commission's finding.

Notably, the Dissent excises incidental testimony that an MRI did not indicate that 

the work accident caused Moore-Ransdell to suffer a "fracture or anything acute like 

that." But an extended quote from the record provides helpful context for this comment: 

Q: And just kind of quickly, I looked through the operative note 

and the MRI film reports and all that. There wasn't a piece of a disc that 

had been -- come loose and had to be removed or a fracture or anything 

acute like that that you specifically addressed, was there?

A: No.

That there was nothing akin to a loosened piece of disc or a fracture is not the 

same as saying that there was not "anything acute." In fact, Dr. Highland diagnosed 

Moore-Ransdell in part with an "acute lumbar strain." Regardless, that there was no 

fracture or injury "like that" does not yield the conclusion that the work accident 

necessarily could not be the prevailing cause of the injury. Nor should we conclude that 

the work accident was not the prevailing cause of the injury based on incidental 

testimony that the source of the pain was disc degeneration or that the strain caused the 

degeneration to become symptomatic or that lumbar strain was an "injury to the muscles 

and ligaments, which is usually a more short-term issue" (emphasis added). While it is 

true that the statute requires more than a simple aggravation of a preexisting condition, it 

is also true that the record reflects Dr. Highland's medical opinion that "in this patient," 

the lumbar strain "was the primary factor" of the overall condition. Dr. Highland's expert 

medical opinion may leave open the possibility that a lumbar strain in another patient 
19

would not necessarily be the prevailing cause of a similar medical condition, but 

surmising what might hypothetically be the case in another patient ignores what Dr. 

Highland testified about in "this patient." There is no conflict in Dr. Highland's 

testimony, and even if there were, the Commission is free to believe some, all or none of 

any witness's testimony, so the minor portions which the dissent argues are in conflict 

may have been found not to be credible. Additionally, our standard of review is clear that 

"it is irrelevant that there is supportive evidence for the contrary finding." Hornbeck, 370 

S.W.3d at 629. The record as a whole, read in proper context, is clear that Dr. Highland 

was not merely using conclusory "magic words" in testifying that the workplace accident 

was the "prevailing factor" in Moore-Ransdell's medical condition.

Point Two is denied.

CONCLUSION

The Commission's final award is affirmed.

DISSENTING OPINION

The Labor and Industrial Relations Commission concluded that a workplace accident in 

which Tammy Moore-Ransdell squatted and twisted to reach into a low, over-filled filing cabinet 

drawer was the prevailing factor causing her permanent partial disability. Because I believe this 

conclusion is unsupported by sufficient competent evidence in the record considered as a whole, 

I respectfully dissent from affirmance of the Commission‟s final award.

As the majority explains, when competing medical causation testimony is presented, it is 

the Commission‟s prerogative to choose which testimony to believe. See, e.g., Bond v. Site Line 

Surveying, 322 S.W.3d 165, 171 (Mo. App. W.D. 2010). In this case, the Commission found 

that the testimony of Moore-Ransdell‟s treating orthopedic surgeon, Dr. Thomas Highland, was 

the most credible concerning the cause of her disability. And Dr. Highland testified, to a 

reasonable degree of medical certainty, that the February 26, 2008 workplace incident was “the 

prevailing cause” and “primary factor” which produced the medical condition which rendered 

her permanently partially disabled.
2

The majority‟s analysis of the causation issue essentially ends here. And normally, I 

would tend to agree that, if a medical expert has testified that a workplace accident was the 

prevailing factor causing a disability, and the Commission indicates that it believes that 

testimony, we are required to defer to the Commission‟s credibility determination, and affirm.

But our review function is not limited simply to determining whether any evidence in the 

record supports the Commission‟s decision. Instead, Article V, § 18 of the Missouri Constitution 

requires us to decide whether the Commission‟s decision is “supported by competent and 

substantial evidence upon the whole record.” (Emphasis added.) The Missouri Supreme Court 

has explained that, under the constitutional standard, “[w]hether the award is supported by 

competent and substantial evidence is judged by examining the evidence in the context of the 

whole record.” Hampton v. Big Boy Steel Erection, 121 S.W.3d 220, 223 (Mo. banc 2003). “A 

reviewing court considers whether the Commission „could have reasonably made its findings, 

and reached its result, upon consideration of all the evidence before it.‟” Hornbeck v. Spectra 

Painting, Inc., 370 S.W.3d 624, 629 (Mo. banc 2012) (quoting Wood v. Wagner Elec. Corp., 197 

S.W.2d 647, 649 (Mo. banc 1946)). Importantly, in conducting our review we do not view the 

evidence in a light most favorable to the Commission‟s decision. Hampton, 121 S.W.3d at 223 

(overruling decades of contrary precedent on this point).

In this case, the rule that we must consider the whole record dovetails with a second wellestablished rule: “[t]he ultimate importance of the expert testimony is to be determined from the 

testimony as a whole.” McGrath v. Satellite Sprinkler Sys., Inc., 877 S.W.2d 704, 708 (Mo. 

App. E.D. 1994) (overruled on other grounds by Hampton, 121 S.W.3d 220).1 In addition, an 

 

1 Quoted in Thorsen v. Sachs Elec. Co., 52 S.W.3d 611, 619 (Mo. App. W.D. 2001) (overruled on other 

grounds by Hampton, 121 S.W.3d 220); see also, e.g., Hinrichs v. Young, 403 S.W.2d 642, 646 (Mo. 1966); 

Morales v. State, 323 S.W.3d 466, 471 (Mo. App. E.D. 2010) (“In determining whether the expert's opinion is

expert‟s expression of an ultimate conclusion, standing alone, does not constitute substantial 

competent evidence to support an administrative decision; instead, the expert must provide 

specifics explaining how and why his or her opinions apply to a particular case.2

Therefore, the fact that Dr. Highland may have “said the magic words,” by expressing an 

ultimate causation opinion which parroted the statutory standard, does not end our inquiry. We 

must look beyond Dr. Highland‟s statement of his ultimate conclusions.

The issue here is not one of choosing between competing medical theories – the 

Commission has already done that. The issue, instead, is determining what Dr. Highland’s 

testimony means, when considered in the context of that testimony as a whole.

Looking beyond the conclusory statements on which the majority relies, the remainder of 

Dr. Highland‟s testimony, and his medical records, establish that Randolph County is not liable 

for Moore-Ransdell‟s permanent disability. Instead, Dr. Highland‟s testimony establishes that 

the February 2008 work accident merely triggered Moore-Ransdell‟s preexisting degenerative 

disc disease to become symptomatic, and that it was this preexisting degenerative condition – not

the workplace incident – which caused her permanent partial disability.

Dr. Highland testified that, before the work accident, Moore-Ransdell had degenerative 

disc disease, which is a condition that progresses over time due to aging and normal activities. 

The progression of Moore-Ransdell‟s condition may also have been exacerbated by her thirtyseven-year smoking habit. Dr. Highland testified that people with degenerative disc disease like

substantial and competent evidence); Kansas City Power & Light Co. v. Searcy, 28 S.W.3d 891, 896 (Mo. App.

Moore-Ransdell can experience pain, and even the need for surgery, spontaneously and without 

any work-related accident.

Dr. Highland testified that the February 2008 work accident caused Moore-Ransdell to 

suffer a lumbar strain. He explained that this lumbar strain was an “injury to the muscles and 

ligaments, which is usually a more . . . short-term issue.” Dr. Highland did not find, and the 

MRIs did not indicate, that the work accident caused Moore-Ransdell to suffer a “fracture or 

anything acute like that.” 

As opposed to the “short-term issue” presented by the lumbar strain, Dr. Highland 

testified that “the continued pain” that Moore-Ransdell experienced “was from the deteriorating 

discs that she had.” Dr. Highland stated that it was this continuing pain from Moore-Ransdell‟s 

underlying degenerative disc condition that he treated; in particular, he testified that “that the 

primary problem that the [three-level fusion] surgery addressed was the underlying degenerative 

condition of the back that had just become symptom[at]ic.”

Importantly, Dr. Highland testified that the February 2008 incident did not cause MooreRansdell‟s degenerative disc condition to become worse. Instead, he stated unequivocally that 

the workplace accident “didn‟t advance the degeneration of the spine. It just caused the 

degeneration to become symptomatic.” In other words, the workplace accident merely 

“triggered a pain from the underlying discs.” Dr. Highland agreed “that any similar incident, 

even a minor one outside of work, could have just as easily triggered some kind of pain 

mechanism” in Moore-Ransdell‟s back.

Dr. Highland‟s medical records are consistent with his deposition testimony. Thus, Dr. 

Highland‟s notes on his initial visit with Moore-Ransdell in May 2008 identify disc degeneration 

and stenosis as the source of her complaints:
5

I reviewed her x-rays she brought with her . . . Her lumbar spine shows 

three-level degenerative disease at L3-4, 4-5 and 5-1, but she has some bulging of 

the 4-5 disc and it is causing some stenosis. There is some facet hypertrophy 

probably contributing, but there is some stenosis at 4-5. I think this is where her 

problem is coming from.

Dr. Highland did not see Moore-Ransdell for approximately two years from August 2008 

until August 2010. His notes from her August 30, 2010 visit state the following as his entire 

“Impression” of her condition: “Severe degenerative disc disease L5-S1 with mild degenerative 

disc disease at L3-L4 and L4-L5.”

Following her August 2010 visit, an MRI was taken of Moore-Ransdell‟s lumbar spine. 

Based on the MRI results, Dr. Highland‟s told her that she required a three-level spinal fusion to 

treat the significant disc degeneration from which she suffered. His notes state:

I talked to Tammy Ransdell about her MRI scan. It does show further 

degeneration at L3-L4 and L4-L5 with some inflammatory changes at L5-S1. She 

has increasing bulging of the L3-L4 disc with some nerve root compression at that 

level.

I told her I thought she needed to treat this with an anterior fusion and we 

should possibly consider a laminotomy at L3-L4 and L4-L5, but I thought her 

primary surgery needed to be an anterior fusion at those three levels.

Finally, in a letter to Moore-Ransdell‟s counsel in October 2010, Dr. Highland again 

stated that her degenerative disc condition was the cause of her continuing pain:

[Moore-Ransdell] came back to see me in August 2010 because of 

persistent pain in her back and increasing pain and numbness and weakness in the 

left leg. I re-evaluated her including x-rays and an MRI scan. She has continuing 

degeneration of all three segments and increasing stenosis. She has continuing 

degeneration of all three segments in her back which were the source of her pain. 

When I saw her in 2008 it included L3-4, L4-5 and L5-S1.

(Emphasis added.)3

In his October 2010 letter, and in a subsequent letter to counsel in January 2012, Dr. Highland stated that 

the “[i]nternal disc disruption to L3-4, L4-5 and L5-S1” which Moore-Ransdell was experiencing was “secondary to 

work injury in February 2008,” and that her need for surgery was directly related to the February 2008 incident. Dr. 

Highland also testified on direct examination during his deposition that the workplace incident “caused” the 

condition which he treated with surgery. These statements support the conclusion that the February 2008 workplace 
6

Reviewing Dr. Highland‟s testimony and clinical notes in their entirety establishes that, 

while the February 2008 incident may have triggered continuing pain from Moore-Ransdell‟s 

degenerative disc condition, it is the degenerative condition – not the February 2008 incident –

which is the prevailing factor causing Moore-Ransdell‟s ongoing disability. In these 

circumstances, the Commission‟s final award must be reversed. As amended in 2005, 

§ 287.020.3(1)4requires that, to be compensable, a workplace accident must be “the prevailing 

factor in causing both the resulting medical condition and disability,” meaning that the work 

accident is the “primary factor, in relation to any other factor, causing both the resulting medical 

condition and disability.” The statute makes emphatically clear that “[a]n injury is not 

compensable because work was a triggering or precipitating factor.” § 287.020.2. It also 

specifies that “[o]rdinary, gradual deterioration, or progressive degeneration of the body caused 

by aging or by the normal activities of day-to-day living shall not be compensable.” 

§§ 287.067.2, .3. Under the 2005 amendments to the Worker‟s Compensation Law, “[i]t is not 

sufficient that the [work-related] event simply aggravates a preexisting condition.” Johnson v. 

Indiana W. Express, Inc., 281 S.W.3d 885, 892-93 (Mo. App. S.D. 2009) (citing Gordon v. City 

of Ellisville, 268 S.W.3d 454, 459 (Mo. App. E.D. 2008)). 

Fairly read in its entirety, Dr. Highland‟s testimony shows only that the February 2008 

workplace incident triggered symptoms from Moore-Ransdell‟s pre-existing degenerative disc 

condition. The prevailing factor causing the continuing pain, surgical treatment, and permanent 

disability is Moore-Ransdell‟s pre-existing degenerative disc condition, not the lumbar strain 

 

accident was a “but for” cause of Moore-Ransdell‟s degenerative disc condition becoming symptomatic when it did. 

But this sort of “but for” causation is not sufficient to establish compensability under the “prevailing factor” 

standard. See, e.g., Mo. Alliance for Retired Ams. v. Dep’t of Labor & Indus. Relations, 277 S.W.3d 670, 684-85 

(Mo. banc 2009) (Teitelman, J., dissenting) (“prevailing factor” causation standard of § 287.030.3(1) exceeds 

proximate causation standard applicable in common-law tort cases).

caused by the February 2008 accident.5 While our standard of review is deferential, “deference 

does not imply abandonment or abdication of judicial review.” Miller–El v. Cockrell, 537 U.S. 

322, 340 (2003).6 We should reverse the Commission‟s final award.

In her briefing, Moore-Ransdell suggests that the issue here is not whether the workplace accident was the 

“prevailing factor” causing a compensable injury, but instead whether particular medical treatments were necessary 

to cure or relieve the effects of the compensable injury she undeniably suffered (namely, the lumbar strain). MooreRansdell cites Hornbeck v. Spectra Painting Inc., 370 S.W.3d 624, 633-36 (Mo. banc 2012), and Tillotson v. St. 

Joseph Medical Center, 347 S.W.3d 511, 517-21 (Mo. App. W.D. 2011), to support her argument. It is clear from 

the record, however, that the Commission‟s disability determination is based on the continuing pain Moore-Ransdell 

suffers as a result of what Dr. Highland testified was a degenerative disc condition. Moreover, as explained in the 

text, Dr. Highland‟s testimony establishes that the medical treatment he provided to Moore-Ransdell related solely 

to the degenerative disc condition, not to the “short-term” lumbar strain which may have triggered her degenerative 

condition. All of the medical expenses for which Moore-Ransdell sought to recover were for dates of service in 

October 2010 or thereafter, more than 2 1⁄2 years after the filing-cabinet incident.

significance of that distinction.”
