Authors: Mesregah Mohamed 
Published: September 2017

Category: Hindfoot Introduction/Purpose: The operative treatment of calcaneal fractures has been a controversial topic. Open reduction and internal fixation is associated with a high incidence of postoperative soft tissue complications. Closed reduction and percutaneous K-wires fixation was used to preserve soft tissue. The aim of our study is to evaluate the outcome of closed reduction and percutaneous K-wires fixation of displaced intra-articular calcaneal fractures. Methods: Twenty two displaced intra-articular calcaneal fractures were treated by closed reduction and percutaneous K-wires fixation. The clinical evaluation was based on Maryland Foot Score. According to Sander’s Classification, Eleven fractures were type II, nine were type III and two were type IV. Bimanual compression across the calcaneus was applied to reduce the calcaneal width. A Schanz screw was inserted into the calcaneal tuberosity and was forcibly pushed downwards to elevate the depressed fragment. Two parallel 2 mm K-wires were placed from the posterior inferior corner of the calcaneus across the posterior facet and into the talar body. The reduction of the articular surface was maintained by two crossing subchondral 2 mm K-wires. If the reduction was not satisfactory, a 1-2 cm long transverse incision was used just below the tip of the lateral malleolus. A small tipped periosteal elevator was introduced to elevate the depressed fragment before K-wire fixation. Results: The mean follow up period was 7.68 months. The clinical outcome revealed 18 fractures (81.8%) of satisfactory (14 excellent and 4 good), and 4 patients (18.2%) of unsatisfactory results (4 fair and 0 poor). The mean time of radiological union was 11.86 (range 10 – 14) weeks. One patient had pin tract infection. One patient developed heel widening. Conclusion: Closed reduction and percutaneous K-wires fixation of calcaneal fractures minimizes the soft tissue complications and postoperative scar formation. The mini approach for elevation of the depressed posterior facet restores the articular surface and decreases late subtalar arthritis.

Category: Bunion Introduction/Purpose: First Metatarsophalangeal joint (MTPJ) osteoarthritis is a common forefoot disease. It leads to joint surface destruction and erosions limiting function and causing pain. The disease can be classified to mobile and non mobile or traumatic and atraumatic disease. The gold standard for treatment of stage III and IV remains MTPJ arthrodesis. In this case series we demonstrate MTPJ arthroplasty in mobile MTPJ with stable first interphalangeal joint (IPJ) can achieve short and medium-term results that are comparable to arthrodesis with high satisfaction rate. Methods: Retrospective analysis of 48 MTPJ arthroplasties performed by single surgeon in the period between 2011 to 2016. Patient were included if they had mobile first MTPJ osteoarthritis in the absence of IPJ hypermobility. The Surgical procedure included resurfacing the 1st metatarsal head using Arthrosurface® Hemicap implant and Extensor Digitorum Brevis (EDB) graft on the phalangeal surface of the joint. Radiological parameters collected using weight bearing x-rays prior to surgery, immediate radiological correction after surgery, 6 month and 2 years radiological analysis following the index surgery. Physiotherapy data were collected by senior physiotherapist prospectively during the time of postoperative rehabilitations and it included AOFAS and VAS scores. Results: 48 patients underwent 1st MTP joint arthroplasty using Arthrosurface® Hemicap implant for the metatarsal head with EDB graft on the phalangeal aspect. 44 patients had primary OA of the 1st MTP joint, 4 were conversion of MTPJ arthrodesis to arthroplasty and 3 were treated for non-union of MTP joint arthrodesis. Average postoperative ROM in the sagittal plane was 30 degrees and no valgus deformity in the coronal plane. 3 Patients (0.68%) had residual pain following the surgery due to soft tissue impingement and required further surgical intervention. 1 patient remained dissatisfied after the revision surgery. Conclusion: In short to medium-term follow up, the first MTP joint arthroplasty with Arthrosurface® implant and EDB graft provides an excellent functional outcome in the management of moderate to severe OA. In some selected cases this can be an option for treatment of patient with failed arthrodesis or patients requiring the reversal of the arthrodesis due to other issues.
Intramedullary Nail Fixation of the Fibula as a Treatment Alternative of Ankle Fractures in a High Risk Patient Population
Authors: Moody Christian , Weatherby Brian 
Published: September 2017

Category: Trauma Introduction/Purpose: Traditional plate osteosynthesis for ankle fractures in a high risk patient population can predispose to complications as a result of the necessary soft tissue dissection and periosteal stripping. Complication rates among patients with multiple comorbidities has been shown to be as high as 30% in those who undergo traditional plate and screw fixation. 1 An alternative fixation construct, thought not widely used or recognized in the American literature is the locking intramedullary fibular nail. Intramedullary nails offer the theoretical advantages of stable fixation while utilizing smaller, percutaneous incisions and no periosteal stripping. The purpose of this study is to analyze the outcomes and complications of high risk patients who underwent ankle surgery using the intramedullary fibular nail. Methods: The medical records of all high risk patients who underwent ankle fracture fixation with a locking intramedullary fibular nail from 1/2011 through 6/2015 at our institution were reviewed. Fracture patterns included unstable lateral malleolar, bimalleolar, and trimalleolar fractures. Patients were considered high risk if they had medical comorbidities at the time of injury that have been shown in current literature to increase surgical complication risk. These comorbidities include neuropathy, uncontrolled diabetes, peripheral vascular disease, congestive heart failure, etc. We recorded patient demographics, fracture type, period of post-op NWB, time until discharge, time to weight bearing, complications, tourniquet time, size and length of nail implanted, and estimated blood loss. Attempts were made to contact all patients to complete a follow-up questionnaire regarding their satisfaction. Results: Twenty-two high risk patients with 23 ankle fracture were included. The average age was 64.8 years (SD 10.2, range 41- 82). The average follow up was 5.7 months (SD 5.7, range 2-30). There were no surgical site infections, wound complications, or non-unions. Two (8.7%) required a return to the operating room for symptomatic screw removal. The average tourniquet time was 35.8 minutes (SD 20.1, range 0-72) and the average operative time was 49.3 minutes (SD 14.3, range 25-70) respectively. The Olerud & Molander average score was 77.9 (SD 17.7, range 40-100). Fourteen of the twenty two patients could be contacted for a follow up questionnaire and 13 of the 14 (93%) said they were either very satisfied (64%) or satisfied (29%) with their injury outcome. Conclusion: The locking intramedullary fibular nail provides an alternative fixation technique that allows for protection of soft tissue, stable fracture fixation and satisfactory outcomes in the high risk patient population.

Category: Lesser Toes, Midfoot/Forefoot Introduction/Purpose: Residual pain and recurrent deformity following forefoot surgery can cause significant disability. In patients with rheumatoid arthritis, first metatarsophalangeal (MTP) joint arthrodesis with lesser metatarsal head resection – often referred to as a rheumatoid forefoot reconstruction – has been shown to be a reliable operation for pain relief and deformity correction. Limited data, however, has been published on outcomes of the same forefoot reconstruction operation in the non- rheumatoid patient. Here, we review our experience with this procedure in patients without rheumatoid disease, hypothesizing improved clinical and radiographic outcomes following surgery. Methods: Following chart review and surveying billing codes, we retrospectively identified patients from 2007-2015 without a diagnosis of rheumatoid arthritis who underwent first MTP arthrodesis with lesser metatarsal head resection (rheumatoid forefoot reconstruction). Phone surveys were then conducted to assess clinical outcomes including pain and satisfaction scores. Preoperative and postoperative radiographs were reviewed for 1, 2 intermetatarsal angle (IMA), hallux valgus angle (HVA), 2nd MTP angle (MTP-2), and lesser MTP alignment (in both sagittal and axial planes). Postoperative radiographs were also assessed for radiographic union. Results: We identified 14 non-rheumatoid patients (16 feet) who underwent forefoot reconstruction – of those, 13 patients (15 feet) were successfully contacted via follow-up phone survey. Mean postoperative follow up was 42.3 (range: 12-76) months from surgery to phone interview. Mean postoperative satisfaction scores were 9.1 (out of 10), and no patients required further surgery after forefoot reconstruction. Pain scores significantly decreased from 6.2 preoperatively to 2.0 postoperatively (P<.001). Radiographic parameters (IMA, HVA, MTP-2, and lesser MTP alignment in the sagittal plane) all improved with surgery (P<.05). All 16 feet achieved union of the first MTP arthrodesis. Conclusion: With decreased pain, high satisfaction rates, and improved radiographic parameters, first MTP arthrodesis coupled with metatarsal head resection (rheumatoid forefoot reconstruction) is a viable surgical option for non-rheumatoid patients who have failed prior attempts at forefoot reconstruction or have chronic forefoot pain with deformity.

Category: Ankle Introduction/Purpose: Evidence increasingly indicates the importance of orthopedic health literacy, sleep quality, and a propensity for pain catastrophization in orthopedic patient outcomes. Using previously validated questionnaires including the Literacy in Musculoskeletal Problems (LiMP), Pain Catastrophization Scale (PCS), and the Pittsburgh Sleep Quality Index (PSQI), this study investigated the relationship between these factors and common functional outcome instruments including the Disability of Arm, Shoulder, and Hand (DASH) and the Foot and Ankle Outcome Score (FAOS). Methods: 245 patients in outpatient clinics of one foot and ankle surgeon and three hand surgeons were approached. Inclusion criteria required age greater than 18, English proficiency, and a newly presenting chief complaint. Enrolled patients completed a demographics form, LiMP, PCS, PSQI, and the DASH or FAOS based on extremity. Clinical history was reviewed retrospectively. DASH and FAOS scores were normalized to the same scale (0 – 100, best to worst) and termed “functional survey” (FS). Correlations were calculated between FS scores, subjective questionnaires, and demographic/clinical information. For the variables of race and education level, one-way ANOVA analysis was conducted to determine if FS scores differed based on these variables. Variables that were significantly correlated with FS score were entered into a multivariate linear regression analysis to assess their effect on FS score. Results: 231 patients (131 hand/wrist, 100 foot/ankle) were enrolled and completed all questionnaires. ANOVA analysis found that there were no significant differences in FS scores based on education or race (p > 0.05). Multivariate regression analysis was conducted with FS score as the dependent variable, and factors that were significantly correlated with FS score, including PCS, PSQI Global Score, visit type (trauma vs. non-trauma), and insurance type (private vs. public) as the independent variables. Health literacy was not significantly correlated with OS score. Results from this analysis can be found in Table 1. The model significantly (p < 0.05) accounted for 19.2% of variation in OS score. Conclusion: There is a strong correlation between tendency to catastrophize pain, sleep quality, and FS score. Every 1 unit increase in the PSQI/PCS corresponds with a 1.8/0.38 point increase in FS score; indicating higher functional disability. Given the strong correlation at baseline, such factors as poorly controlled tendency to catastrophize pain may confound functional outcomes. No significant correlation was noted between health literacy and FS scores. This suggests that an increased level of orthopedic knowledge does not affect perception of functional disability. However, our results show that sleep quality and catastrophic thinking may confound functional outcome scores.

Published: September 2017

Category: Ankle Arthritis Introduction/Purpose: Advanced to end-stage ankle osteoarthritis in highly active older individuals has traditionally been treated using tibiotalar arthrodesis. Distal tibial osteotomy without fibular osteotomy, a type of joint preservation surgery, has garnered attention in recent years, but patient satisfaction has yet to be compared between the two treatments. Objective: To compare distal tibial osteotomy and tibiotalar arthrodesis for ankle osteoarthritis (stage IIIb and above under the Takakura classification) in older individuals. Methods: Subjects and Method: A total of 35 patients aged>60 years old who showed medial ankle arthritis were examined. Patients were either treated with tibiotalar arthrodesis (n=18) or distal tibial osteotomy (n=17). The patients’ mean age was 72.1 years (range, 60–81 years) in the tibiotalar arthrodesis group and 67.2 years (range, 60–80 years) in the distal tibial osteotomy group. For distal tibial osteotomy, a circular external fixator was used in all cases. Osteotomy was performed after performing synovectomy and microfracture surgery using ankle arthroscopy. At the time of fixation with a circular external fixator, foot ring (calcaneal) fixation was also performed. In addition, joint distraction was performed, and distraction arthroplasty was also simultaneously performed. Results: The mean preoperative VAS score was 8.2 for tibiotalar arthrodesis (TA) and 8.0 for distal tibial osteotomy (DTO). The mean postoperative VAS score was 1.9 for TA and 1.7 for DTO. The mean preoperative AOFAS score was 40.1 for TA and 43.1 for DTO. The mean postoperative AOFAS score was 86.2 for TA and 90.0 for DTO. The mean preoperative SF-36 physical component score was 30.5 for TA and 38.5 for DTO. The mean preoperative SF-36 mental component score was 33.5 for TA and 37.5 for DTO. The mean postoperative SF-36 physical component score was 42.5 for TA and 56.4 for DTO. It was significantly higher with the DTO (p<0.05). Conclusion: The mean postoperative SF-36 mental component score was 44.0 for TA and 59.7 for DTO. It was significantly higher with the DTO (p<0.05).Superior SF-36 scores were obtained for DTO compared to TA. The fact that the Japanese lifestyle involves tatami mats was thought to have contributed to the superiority of DTO in patient satisfaction.
Screw in Lisfranc Ligament
Authors: Panchbhavi Vinod , Sierra Stephen 
Published: September 2017

Category: Trauma Introduction/Purpose: The Lisfranc ligament is an interosseous ligament connecting the medial cuneiform with the second metatarsal. Current treatment of displaced Lisfranc injury is rigid fixation using a transarticular screw. The purpose of this study was to observe the amount of ligamentous disruption with the placement of a transarticular screw from the second metatarsal to the medial cuneiform. Methods: This cadaveric study included a total of 15 preserved cadavers and 23 feet. Blunt dissection down to bone, with removal of soft tissue, was performed on each foot for visualization of the Lisfranc joint. A guide-wire was inserted in a dorsolateral to plantar medial direction from the base of the second metatarsal into the medial cuneiform. Then over the guide- wire a 40 mm, 4.0 partially threaded, cannulated screw was inserted. The Lisfranc ligament was then carefully identified with more dissection. The screw was then removed. Separation of the second metatarsal from medial cuneiform was performed by transecting the dorsal, Lisfranc (interosseous), and plantar ligaments. Digital photographs of the Lisfranc ligament, medial cuneiform and second metatarsal articular surfaces were recorded and measurements were taken. Results: Of the 23 feet, the screw came in contact with the Lifranc ligament in 20 feet. The screw fully penetrated the ligament in 7 feet, partially disrupted it in 4 feet, and had <1 mm of contact in 9 feet. In 3 feet, there was no contact with the ligament with an average distance of 1.5 mm. Conclusion: Our results reveal the amount of disruption a transarticular screw, placed in a dorsolateral to plantar medial direction, will have on the Lisfranc ligament. Although the screw came into contact with the ligament in 20 out of 23 feet, only 13 feet had partial disruption or minimal contact and 3 feet had no contact at all. This is clinically relevant because ligamentous damage due to insertion and/or presence of screw in anatomic location of the ligament may interfere with its healing.
The NFL Combine as a Predictor of On-field Success
Authors: Parekh Selene , Patel Akul 
Published: September 2017

Category: Sports Introduction/Purpose: The NFL scouting combine is utilized annually by NFL franchises for prospect evaluation. It consists of a series of physical tests, medical evaluation, and intelligence exam (the Wonderlic). The relationship between physical measures such as vertical jump height and subsequent on-field performance has not been adequately explored in the medical literature. Such information could be useful for athletes training for a career in football or for athletes returning from injury seeking to maximize their chance of subsequent on-field success. The purpose of this study is to see if physical characteristics, as measured in the combine, are correlated with subsequent on-field performance. Methods: Physical testing performance at the combine for all NFL positions from 2006 to 2013 was obtained from a publically available NFL draft scout website. NFL performance data for all players (n=1306) who entered the combine was obtained from the commercial website Pro Football Reference. Pearson’s linear correlation coefficients were utilized to analyze relationships between combine physical and intelligence test measurements and subsequent on-field performance for each offensive and defensive position. On-field performance was measured using a wide variety output statistics. Examples include yards per carry or reception and yards per attempt for offensive positions and sacks and tackles per game for defensive positions. Results: A number of combine measures were statistically significantly associated with improved on-field NFL performance (p<0.05). These measures differed per position and for offensive and defensive players and varied in correlation strength. For example, quarterbacks and running backs with faster forty-yard dash speeds were associated with better NFL rushing statistics. Conclusion: Certain physical characteristics, as measured in the NFL combine, are associated with improved on-field performance in the NFL. Further studies are needed to discern the relationship between the NFL combine and subsequent on- field performance.

Published: September 2017

Category: Diabetes Introduction/Purpose: Investigations using the Medical Outcomes Study Short Form 36 Healthy Survey (SF-36) and the American Orthopaedic Foot and Ankle Society Diabetic Foot Questionnaire (AOFAS-DFQ) have demonstrated a poor quality of life in patients with Charcot Foot arthropathy. The Short Musculoskelatal Function Assessment (SMFA) questionnaire has been widely used in patients with a broad range of musculoskeletal disorders. Methods: Twenty-five consecutive patients undergoing surgical correction for diabetes-related Charcot Foot Arthropathy of the midfoot completed the Short Musculoskeletal Functional Assessment (SMFA) prior to undergoing surgery. There were 16 males and 9 females. The average BMI was 37.35 (range 25.83-50.22), and the average Hemoglobin A1C was 7.54 (range 5.3-10.1) prior to surgery. Results: All twenty-five patients exhibited significant impairment in all six domains of the SMFA (p<0.0001) as compared to the normative data. There was a high correlation between each of the six domains of the SMFA, even after correcting for BMI. Conclusion: Charcot foot severely impairs quality of life in impacted patients beyond the impact of morbid obesity. This impairment equally impacts all of the functional and emotional domains measured with the SMFA as compared with population norms. This investigation provides an excellent benchmark for measuring the impact of surgical correction. In addition, the SMFA appears to be a valid tool for evaluating this complex patient population.

Category: Ankle Introduction/Purpose: Understanding the morphometry of the ankle joint is crucial to improve total ankle replacement (TAR). Despite improvements of the implant material TAR did not reach comparable success rates to total hip or knee arthroplasty. Recent studies queried whether current designs match with the articular geometry. The present study was performed to evaluate the ankle morphometry and thereby gain information about the joint axis. Methods: We analyzed 96 high-resolution CT-scans of complete caucasian cadaver legs. Using the software Mimics and 3-Matic (Materialize) 22 anatomic parameters of the talocrural joint were assessed, including the length, width and surface area of the tibial and talar bearing areas. Additionally the radii of the bearing areas, the medial distal tibial angle and the height of the talar dome were determined. Therefore we analyzed defined sagittal, axial and frontal planes. Results: The radius of the central trochlea tali was 44.6 ± 4.1 mm (mean ± SD). The central trochlea tali arc length was 40.8 ± 3.0 mm and its width was 27.4 ± 2.5 mm. Additionally we determined 47.0 ± 4.4 mm for the tibial sagittal radius, 27.6 ± 3.0 mm for the tibial arc length and 27.4 ± 2.5 mm for the central tibial width. Conclusion: The present study describes the three-dimensional morphometry of the caucasian ankle joint. Our results might be considered for the development of total ankle replacements.
