Authors: Nandakumar Venkata Abinaya , Chattu Vijay Kumar , Kumary Soosanna , Naidu Rahul 
Published: September 2018

Background: Oral health touches every aspect of our lives and still it is been taken for granted. The access and affordability to oral health care services are very limited and expensive especially in developing countries. Objectives: The article highlights the importance of global oral health and how it can tackle the growing noncommunicable diseases (NCDs) epidemic. Dental caries remains a significant problem even among the developed nations affecting 60% to 70 % of the children. Oral cancers, Qat chewing, craniofacial anomalies, and dental trauma contribute significantly to the global burden of diseases. Despite the magnitude of oral illness, there is neglect in global oral health, resulting in lack of combined action and support within the arena. Conclusions: Oral conditions share many common risk factors with NCDs and are also affected by similar social determinants. The Political Declaration of the High-level Meeting on the prevention and control of NCDs recognizes that oral diseases pose a significant burden for many countries and these diseases also share common risk factors of NCDs and can benefit from the multisectoral and multipronged approaches to NCDs. To address the existing inequities and inequalities in oral health care services globally, it is vital to ensure coverage for the poor and disadvantaged populations. Recommendations: There is a great need to develop some measurable oral health goals for global comparison in order to track, reduce oral disease burden, and to promote good oral health thereby advancing global public health.

Published: September 2018

Category: Ankle Arthritis Introduction/Purpose: Total hip and knee arthroplasty (THA and TKA) are performed far more commonly than total ankle arthroplasty (TAA), so patients and the orthopaedic community have a better understanding of the complication profile for THA and TKA than for TAA. The present study compares adverse event rates, the rate of blood transfusion, operative times, length of stay, and the rate of hospital readmission between TAA, THA, and TKA procedures. Methods: Patients were identified who underwent TAA, THA, or TKA during 2006-2016 as part of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP). Multivariate regression was used to compare TAA to THA and TKA in terms of adverse event rates, the rate of blood transfusion, operative times, length of stay, and the rate of hospital readmission. All analyses were fully adjusted for differences in baseline demographic, comorbidity, and procedural characteristics, including type of anesthesia. The level of significance was set at p<0.05. Results: A total of 138,325 patients were identified as having undergone THA, 223,587 TKA, and 839 TAA. The total complication rate was lower for TAA (2.98%) compared to THA (4.92%, p=0.011) and TKA (4.56%, p=0.049; Table 1). Similarly, the rate of blood transfusion was lower for TAA (0.48%) compared to THA (9.66%, p<0.001) and TKA (6.44%, p<0.001). Interestingly, operative time was approximately an hour longer for TAA (157.7 minutes) compared to THA (93.6 minutes, p<0.001) and TKA (93.7 minutes, p<0.001). Length of stay was approximately one day shorter for TAA (1.9 days) compared to THA (2.9 days, p<0.001) and TKA (3.0 days, p<0.001). Finally, the rate of readmission was lower for TAA (1.5%) compared to THA (3.7%, p=0.002) and TKA (3.4%, p=0.005). Conclusion: TAA is a relatively rare procedure to which patients may not have had much exposure. Patients considering TAA are more likely to have had exposure to more common procedures such as THA and TKA (through family, friends, their own procedures, etc.). Patients can be counseled that relative to THA and TKA, TAA is a safer procedure in the perioperative time frame, with significantly lower rates of adverse events, blood transfusion, additional surgery, and hospital readmission. Their procedures can be expected to take longer, but their hospital stays can be expected to be shorter.

Published: September 2018

Category: Ankle Arthritis Introduction/Purpose: Metal component failure in total ankle arthroplasty(TAA) is difficult to treat. Traditionally, to an arthrodesis has been advocated. Revision TAA surgery has become more and more common with availability of revision implants and refinement of bone conserving primary implants. It this study, patient reported results and clinical outcomes are analyzed for patients undergoing revision total ankle arthroplasty. Methods: We retrospectively reviewed prospectively collected data on 45 patients (cases) with a mean age of 63.7 +/-10.2 years who developed loosening or collapse of either major metal component in the primary total ankle arthroplasty. Cases of isolated polyethylene exchange, infection, or extra-articular realignment procedures were excluded. Prospectively collected patient reported outcomes measures including the American Orthopaedic Foot and Ankle Society(AOFAS) hindfoot score, Visual Analog Scale (VAS), Short Form 36 (SF-36), Short Musculoskeletal Function Assessment (SMFA), and the Foot and Ankle Outcomes Score (FAOS) questionnaires were collected. Clinical data was collected through thorough review of the electronic medical record to identify clinical failure defined as explant and second revision or conversion to arthrodesis or amputation. Results: The causes of failure of primary TAA in this study were aseptic loosening of both components (40%), talar component subsidence/loosening (37.7%), tibial loosening (8.8%), coronal talar subluxation (8.8%) and talar malrotation (2.2%). Twenty-four patients (53.3%) underwent revision of all components, nineteen (42.2%) just the talar and polyethylene components, and two (4.4%) the tibial and polyethylene components. The average time to revision was 5.56 years +/- 5.71 with a follow-up of 3.02 years +/- 1.25 after revision. Ten (22.2%) revision arthroplasties required further surgery; five required conversion to arthrodesis and five required second revision TAA. VAS scores, SF36 scores, SMFA scores, AOFAS Hindfoot scores, and FAOS all improved after revision surgery but took 2 years to reach scores comparable to 1 year after primary TAA. Conclusion: Clinical and patient reported results of revision ankle arthroplasty after metal component failure were comparable to those after primary ankle arthroplasty. In our series, 22.2% of revision TAAs required a second revision TAA or arthrodesis surgery. Various prosthesis performed similarly when used in revision scenarios. Patients recovered faster from primary ankle arthroplasty when compared to revision ankle arthroplasty but all scores were comparable by the two-year follow-up visit after revision arthroplasty surgery.

Published: September 2018

Category: Midfoot/Forefoot Introduction/Purpose: Interposition arthroplasty is an interim procedure for the treatment of first metatarsophalangeal osteoarthritis demonstrating excellent survivorship. The procedure is commonly performed at our institution and successful long-term results have been described. Furthermore, we have utilized concentrated, autologous, bone marrow aspirate (BMAC) to augment and accelerate patient recovery, decrease postoperative pain, reduce postoperative narcotic requirement, and improve tissue healing for a variety of ankle and foot pathology. The purpose of this study was to compare the early outcomes of interpositional arthroplasty with patients receiving BMAC augmentation versus controls and to evaluate postoperative analgesia and narcotic requirements. Methods: After IRB approval, patients undergoing interposition arthroplasty for hallux rigidus at our institution from 2009-2014 were identified. All cases were performed using autograft capsular interposition by a single surgeon. 18 BMAC cases with complete records were identified. These were matched to controls in a 1:1 manner by age, gender, and laterality. A retrospective analysis of prospectively collected data was performed. Demographics, clinical range of motion, complications, VAS scoring, FAAM, FFI, AOFAS scores were recorded and analyzed. Postoperative analgesia requirements, narcotic usage, and prescription data were collected. Follow-up was conducted at 2,6,12,24, & 52 weeks postoperatively. Time experiencing pain and time to achieve maximum functional satisfaction were recorded. Results: 89% (32/36) of patients undergoing interposition arthroplasty were female, average age 58 years (range, 39-74). The average number of weeks experiencing pain, narcotic utilization, and time to achieve functional satisfaction was statistically lower in the BMAC group, 11 weeks (range, 6-24) versus controls, 27.4 weeks (range, 6-52), (p=0.001). The number of post-operative days of pain requiring narcotic analgesia was significantly lower in patients receiving BMAC 4.2 days (range, 1-14) compared to controls averaging 13.8 days (range, 2-48) (p=0.02). Both groups demonstrated improvements in pre- and postoperative VAS scores, increase in motion, SF-36, FAAM, FFI, and AOFAS scores at 52 week follow up. There were no failures and there was one superficial infection requiring oral antibiotics. Conclusion: This study confirms that patients undergoing interpositional arthroplasty demonstrate excellent clinical improvements in short-term follow-up with few complications. Moreover, augmentation of this procedure with BMAC results in a significant decrease in narcotic utilization and recovery time post-operatively. BMAC may be a useful adjunct in diminishing postoperative narcotics we prescribe to our patients.

Published: September 2018

Category: Midfoot/Forefoot Introduction/Purpose: The importance of preoperative evaluation of the position and degree of arthritic changes of the medial sesamoid bone before hallux valgus correction is emerging. This is an observational study to evaluate the magnetic resonance imaging (MRI) findings of hallux valgus deformity, and assess the severity of and identify the factors that influence the arthritic changes in medial sesamoid-metatarsal (mSM) joints. Methods: We reviewed weight-bearing anteroposterior radiographs, forefoot axial radiographs and MR images of 514 feet of 405 patients who underwent hallux valgus correction. On MRI, the degrees of the arthritic changes in the first metatarsophalangeal (MTP) and mSM joints were categorized into 5 classes. Binary logistic regression analysis was performed to identify the factors affecting the arthritic changes. Results: The binary logistic regression analysis showed that advanced age, more lateralized position of medial sesamoid bone on forefoot axial radiograph, and higher MRI grade of arthritic change of the 1st MTP joint were significant factors contributing to medial sesamoid arthritis (P <0.001, 0.001. 0.006, respectively). Conclusion: Medial sesamoid arthritis can be assessed using MRI. The position of medial sesamoid bone on forefoot axial radiographs can strongly help predict the possibility of mSM joint arthritis.

Published: September 2018

Category: Lesser Toes Introduction/Purpose: To explore the surgical method of using the modified coughlin osteotomy for surgical treatment of high-grade tailor’s bunion and report the clinical outcomes Methods: From March 2013 to April 2015, the modified coughlin osteotomy was used for surgical treatment of high-grade tailor’s bunion. Twenty-two patients with 31 feet high-grade tailor’s bunion were hospitalized for treament in Xuzhou Central Hospital. There were 3 male (3 feet) and 19 female (28 feet) cases, aged 26 -78 years (mean 45.3y) old. The mean course of the painful bunionette disease was 6.7 years (range, 2 to 38 y). The average 4-5 intermetatarsal angle, fifth metatarsophalangeal angle and lateral deviation of the fifth metatarsal angle were 16.3°±5.1°, 10.7°±3.5° and 5.8°±2.6°, respectively. Main outcome measures included the 4-5 intermetatarsal angle, the fifth metatarsophalangeal angle, pain and appearance. Patients were scored using the American Orthopaedic Foot & Ankle Society (AOFAS) Lesser Toe Metatarsophalangeal-Interphalangeal Scale. Results: All operations were performed with no complications. Primarily healing of the wound was achieved in all cases. All the patients were followed up for a mean time of 17.8 months (range, 6 to 30 months). The mean fracture healing time was 11.6 weeks(range, 6 to 14 weeks), X-ray photograph proved fracture healing with a good positoin.All the patients had satisfactory appearance and sensory function witout callosum and metastatic metatarsalgiaat the final follow-up. The preoperatively average 4- 5 intermetatarsal angle, fifth metatarsophalangeal angle and lateral deviation of the fifth metatarsal angle were 5.9°±1.6°, 6.1°±2.3° and 2.2°±1.2°, respectively. The mean AOFAS score was 89.0±8.4. Conclusion: The modified coughlin osteotomy is a safe and easy treatment option for the high-grade tailor’s bunion deformity and provides patient satisfaction results
Treatment of Hallux Valgus Deformity Using a Suture Button Device
Authors: Gonzalez Tyler , Smith Jeremy , Ready Lauren , Chiodo Christopher 
Published: September 2018

Category: Bunion Introduction/Purpose: Hallux valgus (HV) is commonly treated with proximal or distal first metatarsal osteotomies. Despite good correction, these procedures bear inherent risks such as malunion, nonunion, metatarsal shortening, loss of fixation, and avascular necrosis (AVN). Suture button fixation has been used as another form of HV treatment that avoids the use of corrective osteotomies and maintains reduction of the intermetatarsal angle (IMA). The goal of this study was to assess the radiographic and functional outcomes of patients undergoing HV correction with a distal soft tissue procedure and proximal suture button fixation. Methods: Twenty-two patients underwent HV correction utilizing a distal soft tissue correction and proximal fixation with the Mini TightRope (Arthrex, Inc, Naples, Florida) device. The IMA, hallux valgus angle (HVA), and sesamoid station were measured on radiographs obtained preoperatively as well as in the immediate post-operative period and at final follow-up. Preoperative and postoperative Short Form-36 (SF-36) and Foot and Ankle Ability Measure (FAAM) scores were collected. Postoperative Visual Analog Scale (VAS) scores, complications, and any additional surgical procedures performed were also recorded. Results: Mean follow-up was 27.7 months.The mean preoperative IMA and HVA were 16.9 and 32.6 degrees.The mean immediate postoperative IMA was 5.2 degrees(p<.0001)and the mean HVA was 9.8 degrees(p<.0001).At final follow-up, the mean IMA was 8.2 degrees(p<.0001)and the mean HVA was 16.7 degrees(p<.0001).Sesamoid station assessment at two-week follow-up showed that 22 patients(100%)were in the normal position group;at final follow-up,17 patients(77%)were in the normal position group and five patients(23%)were in the displacement group.Asymptomatic radiographic recurrence was noted in 5 patients(23%)who had a final HVA>20degrees.All components of the FAAM and SF-36 showed improvement from preoperative to final follow-up, although these changes were not statistically significant.The average final postoperative VAS was11.05.Of the 22 cases, three experienced complications, including an intra-operative second metatarsal fracture, a postoperative second metatarsal stress fracture, and a postoperative deep vein thrombosis(DVT). Conclusion: The use of a distal soft tissue procedure in conjunction with proximal suture button fixation is a safe and effective procedure for treating symptomatic HV deformity. Our results show that this technique can correct the IMA, HVA, and sesamoid station without the need for osteotomy and with minimal risk of complications.

Published: September 2018

Category: Ankle Arthritis Introduction/Purpose: Ankle arthritis can be a debilitating disease that results in decreased daily activity and chronic morbidity. Many patients elect for surgical intervention to minimize pain and improve function. To curb costs associated with the increasing demand for total joint arthroplasty (TJA) in the growing elderly Medicare population, CMS announced the Comprehensive Care for Joint Replacement (CJR) model, which included total ankle arthroplasty. To provide continued quality care and cost containment, it is necessary to determine the optimal surgical intervention for patients that could fall within the CJR program. Therefore, we sought to determine the impact of surgical fixation on functional outcomes, systemic utilization, and medical expenditures for patients with ankle arthritis. Methods: We reviewed a prospectively collected and maintained database to identify all patients who underwent a total joint replacement from April 2016 to September 2017. Patients were identified based on DRG codes for primary arthritis of a lower extremity joint, then specifically for foot and ankle, as well as CPT codes for ankle arthroplasty (27702) or ankle arthrodesis (27870/28725). Functional outcomes were assessed based on insurance type. The cohorts were matched for age, comorbidities, and gender. Statistical analysis was performed using chi-squared and paired t-test to assess for differences in patient reported outcomes. Descriptive statistical analysis was used to assess for differences in cost between the cohorts. Results: A total of 573 patients were included.There were 48 replacements and 47 fusions. Arthrodesis procedures costs approximately $6,500 less per case than the system costs for patients who underwent arthroplasty procedures. The average length of stay for patients who underwent total ankle arthroplasty was 1.6 days compared to outpatient surgical centers utilized for most arthrodesis patients. Overall, patients reported improved pain and a 30.96 increase in FAAM scores. Most patients had a global rate of change that was “very much better” or “much better” (68%). Based on insurance type, patients who underwent a total ankle replacement in the CJR program had improved outcomes and lower cost than patients commercially insured. Conclusion: With the CJR, there is greater emphasis on the optimal intervention for elective operations. There should be coordinated efforts to optimize quality care, while minimizing financial waste within the healthcare system. The price differential suggests an annual potential for financial savings as high as $325,000 for a system that supports intervention for ~50 cases per year. As such, these results suggest that arthroplasty may be optimal for patients with severe symptomatic ankle arthritis, while most patients have adequate relief with an ankle fusion. More importantly, quality improvement efforts should focus on the impact of surgical intervention on functional activity.

Published: September 2018

Category: Ankle Introduction/Purpose: The treatment of posterior malleolar fractures is developing. Our previous study on the anatomy of the posterior malleolar fracture identified only 49% of rotational push off fractures of the posterior malleolus had syndesmotic instabilities. This was against general thinking that fixation of such a fragment would stabilize the syndesmosis. Our aim in this study was to identify the extent of the posterior inferior tibiofibular ligament insertion on the posterior tibia and its relation to push off fractures. Methods: We examined 10 cadaveric lower limbs that had been preserved for dissection at the Human Anatomy and Resource Centre at Liverpool University in a solution of formaldehyde. The lower limbs were carefully dissected to identify the ligamentous structures on the posterior aspect of the ankle. Results: In all specimens, the tibial insertion of the PITFL encompassed 1/3 of the distal posterior tibia. In addition, the posterior intermalleolar ligament inserted onto the posterior tibia just medial to the tibialis posterior groove. Thus a rotational push off fracture would only cause syndesmotic injury if greater than a 3 rd of the posterior tibia was injured or occurred in combination with a ligamentous injury. This is in keeping with the clinical findings of only 49% syndesmotic instabilities with Haraguchi type 1 posterior malleolar fractures. Conclusion: Haraguchi type 1 posterior malleolar fractures (less than a 3 rd of the width of the posterior tibia) are unlikely to cause syndesmotic instabilities without the addition of a ligamentous injury.

Published: September 2018

Category: Ankle Introduction/Purpose: A controlled ankle movement (CAM) walker boot is often prescribed for patients with a lower extremity injury or disorder. CAM boot wear, however, may cause gait alterations and leg-length discrepancy, which are commonly associated with joint pain. This study evaluates the location, frequency and duration of secondary site pain relating to immobilization in a CAM walker boot. Methods: Patients wearing a CAM walker boot for treatment of a foot or ankle injury were prospectively enrolled and evaluated for new or worsened secondary site pain. Surveys at four time points were completed to evaluate the presence of secondary site pain, its severity, and its impact on overall function. Results: The final study population included 46 patients (mean age 49 years). At transition out of the boot (mean, 4.2 weeks), 31 patients (67%) reported secondary site pain either new or worse than baseline with an average of 1.6 secondary pain sites. The secondary sites most susceptible to pain were the lower back, contralateral hip, and ipsilateral knee. A majority (84%) of these pains began within the first two weeks of boot wear. Secondary site pain was less common after transition out of the boot: 18 patients (39%) at 1 month, 15 patients (33%) at 3 months. The mean VAS for secondary site pains at transition out of boot was 51.2. Statistical significance was found correlating secondary site pain and a history of chronic pain (P=.04). Conclusion: Secondary site pain after CAM walker boot wear was common. The frequency and severity of pain lessened with time after transition out of the boot. Yet, one-third of patients still had new or worsened secondary site pain three months after cessation of boot wear.
