BackgroundAnkle-foot conditions are ubiquitous in the US Military. The objective of this study was to evaluate the burden and associated factors of Achilles tendinopathy (AT).MethodsThe Defense Medical Epidemiology Database was used to identify all diagnosed AT in military personnel from 2006 to 2015. Prevalence of AT was calculated and compared by year, service branch, and military rank. Unadjusted and adjusted assessment of injury risk were calculated.ResultsOfficers incurred 37,939 episodes at a prevalence of 17.65 per 1000 (male officers: 18.20 per 1000; female officers: 14.80 per 1000). Among enlisted personnel, there were 116,122 episodes of AT that occurred in 12.22 per 1000 (male enlisted: 12.07 per 1000; female enlisted: 13.22 per 1000). All officer specialties had significantly higher risk of AT episodes compared to the ground and naval gunfire officers (PR: 1.04-1.43), with aviation demonstrating a significant protective effect (PR: 0.65). Among enlisted specialties, maritime/naval specialties had reduced risk (PR: 0.82), with all specialties (except aviation) having increased risk of AT compared to infantry (PR: 1.07-1.71). There were multiple associated factors identified, to include sex, age, rank, military occupation, and service branch.ConclusionsAT was ubiquitous in the US military, with a progressive increase in prevalence during the study epoch. There were multiple associated factors identified, to include sex, age, rank, military occupation, and service branch. These findings highlight both the need for prophylactic interventions and identification of the populations with the greatest need.

Background This study assessed patient perceptions of the Physician Payments Sunshine Act and opinions toward physicians who receive gifts and/or payments from pharmaceutical or medical device companies. Methods During their office visit, patients attending different specialty clinics volunteered to complete our survey. The survey asks if the patient knows what the Sunshine Act is, then asks questions on 5-point response scales to assess the patient's opinions toward physicians who receive compensation from companies, their self-rated knowledge of physician compensation, and how they believe this compensation affects the cost of care. Results Over 13 months, 523 responses were collected: 8.6% of patients reported having knowledge of the Sunshine Act, 56.8% rated their knowledge of physician compensations as “poor,” and 67.1% agreed with the statement that patients should be aware of the compensation physicians receive. When asked how their opinion toward their physician would change if they learned the physician received free meals or gifts from companies, 58.9% replied “not at all,” and 36.11% of patients did not believe their cost of care would increase if their physician received compensation from companies. Conclusions Most patients were unfamiliar with the Sunshine Act, and believe their knowledge of physician compensation is poor. Over half of the respondents would not change their opinion of their physician based on knowledge of their physician receiving payments/gifts from companies, and over one-third of respondents did not believe such compensation increased the cost of care. The majority of respondents agreed that patients should be aware of payments/gifts to physicians.

Introduction: Women have historically been underrepresented in orthopaedics. This study analyzes the geographic distribution of female orthopaedic foot and ankle (OFA) surgeons, as well as geographic patterns between their training locations and current practices. Methods: American Orthopaedic Foot and Ankle Society (AOFAS) data regarding fellowship completion from 1988 to 2021 were analyzed. Internet searches were then performed to identify medical school, residency, and current practice locations of individual surgeons. States were categorized into regions and divisions based on US Census Bureau guidelines. Results: Of the 1088 OFA surgeons analyzed, 166 (15.26%) were women and 922 (84.74%) were men. The South has a higher number of female OFA surgeons; however, this region and the Midwest have the lowest percentages of female representation. The West and Northeast had significantly higher percentages of female representation and higher retention rates for women. There was high variability in the number and percentage of female OFA surgeons in divisions both within and between regions. Conclusion: Although the number of female OFA surgeons has increased, their representation remains low. Geographically, the East South Central division of the United States consistently had the least number of OFA surgeons, whereas the South Atlantic division had the highest. Level of Evidence: Not applicable.

Posterior tibial tendon dysfunction (PTTD) and tarsal tunnel syndrome (TTS) are debilitating conditions reported to occur after ankle sprain due to their proximity to the ankle complex. The objective of this study was to investigate the incidence of PTTD and TTS in the 2 years following an ankle sprain and which variables are associated with its onset. In total, 22,966 individuals in the Military Health System diagnosed with ankle sprain between 2010 and 2011 were followed for 2 years. The incidence of PTTD and TTS after ankle sprain was identified. Binary logistic regression was used to identify potential demographic or medical history factors associated with PTTD or TTS. In total, 617 (2.7%) received a PTTD diagnosis and 127 (0.6%) received a TTS diagnosis. Active-duty status (odds ratio [OR] 2.18, 95% confidence interval [CI] 1.70–2.79), increasing age (OR 1.03, 95% CI 1.02–1.04), female sex (OR 1.58, 95% CI 1.28–1.95), and if the sprain location was specified by the diagnosis (versus unspecified location) and did not include a fracture contributed to significantly higher (p

Background: Female representation varies geographically among orthopaedic residency programs, with the southern region of the United States reported as having relatively lower rates of female orthopaedic surgeons. Purpose: To determine the gender and geographic distributions of US-based orthopaedic sports medicine surgeons and analyze geographic patterns between their training locations and present-day practices. Study Design: Cross-sectional study. Methods: American Orthopedic Society of Sports Medicine (AOSSM) fellowship completion data from the 2016-2021 academic years were analyzed with regard to gender and fellowship location. Medical school, residency, and current practice locations were obtained via internet searches for all individuals identified within the databases. Locations were categorized into regions based on the US Census Bureau definitions. Descriptive statistical analysis was performed on the data. Results: A total of 1268 sports orthopaedic surgeons who graduated fellowship from 2016 to 2021 were analyzed: 141 (11%) were female and 1127 (89%) were male. The percentage of female sports medicine surgeons in fellowship remained constant (11%-12%) from 2016 to 2021. On average, the annual percentage of female orthopaedic sports medicine fellows was 7.2% in the South, 10.4% in the West, 14.2% in the Midwest, and 14.7% in the Northeast. Based on the orthopaedic sports medicine fellowship graduates from 2016 to 2021, the mean percentage of current female orthopaedic sports medicine surgeons in practice was 7.4% in the South, 11.7% in the Northeast, 12.8% in the Midwest, and 14.4% in the West. Conclusion: Approximately 11% of our sample was female; however, this percentage varied heavily by region, with the southern region having significantly lower rates of gender diversity.

Ankle fractures are common injuries treated by orthopedists. Indications for operative repair of deltoid ligament (DL) injuries in ankle fracture patients are debated. The purpose of this review is to determine the indications for operative DL repair. Ovid MEDLINE, CINAHL, and Scopus were searched up to December 2019. Web of Science was searched up to August 2018. Search terms included "Deltoid" and "Ligament" or "Ligaments." Comparative studies assessing conservative vs operative DL repair were searched for. Articles meeting inclusion criteria were screened in two stages to determine eligibility. Out of 1,542 articles, nine were included in our qualitative synthesis. These nine studies included 449 patients, of which 233 were treated with open reduction internal fixation (ORIF) with or without trans-syndesmotic (TS) screw fixation, and 205 of which were treated with ORIF with DL repair. The remaining 21 patients were managed nonoperatively, had no evidence of DL injury, or were lost to follow-up. There is a lower rate of malreduction associated with DL repair compared to TS screw fixation. Moreover, DL repair may be useful in treating patients with Weber Type C fractures, concomitant DL-syndesmotic disruption, or residual valgus instability following ORIF in isolated lateral malleolar fractures.

Hallux valgus is one of the most common conditions treated by foot and ankle orthopedists; over 140 surgical procedures have been developed for management of the condition. A rare complication of hallux valgus repair is nonunion, and the literature regarding nonunion after hallux valgus repair is correspondingly sparse. We present a 39-year-old active duty male who underwent operative management after developing nonunion and transfer metatarsalgia following a proximal oblique metatarsal osteotomy. The patient underwent nonunion correction and metatarsal lengthening via bone allografting. No complications were observed during the intra- or perioperative periods. At 2.5-years postoperatively, the patient’s symptoms had largely resolved. He expressed high satisfaction with his outcome and was able to continue activity duty. Our findings indicate that nonunion repair can have excellent clinical outcomes with high patient satisfaction, even in an active military population.

Background Ankle osteoarthritis is increasing, thus creating greater demand for high-volume total ankle arthroplasty (TAA) surgeons. The Medicare Provider Utilization and Payment Data Public Use File (MPUPD-PUF) provides volume and reimbursement data for procedures performed by physicians participating in Medicare. This study analyzes surgeon prevalence, surgeon distribution, and factors affecting surgeon prevalence in metropolitan areas. Methods The MPUPD-PUF was reviewed from 2012 to 2015, and data were extracted for physicians performing ≥11 TAA procedures. Physicians in metropolitan areas (population >1 million) were grouped together, and reimbursement, number of high-volume surgeons, and procedures were calculated. Presence of an American Orthopaedic Foot and Ankle Society (AOFAS) fellowship program was analyzed for associations with high-volume TAA surgeons. Results Fifty-three surgeons performed ≥11 TAA procedures (1,960 total) covered by Medicare. Of these surgeons, 66% practice in metropolitan areas with a population >1 million. Fifty-one percent of US major metropolitan areas contained no surgeon who submitted >10 traditional Medicare claims for TAA. Areas with an AOFAS fellowship had nominally more TAA claims submitted. Conclusions The distribution of high-volume TAA surgeons among major metropolitan areas in the United States is highly unequal. Analyzing the data with this method aids in targeting TAA surgeons to currently underserved areas. Levels of Evidence Level IV: Retrospective-comparative study

Vitamin D is critically important to numerous physiologic functions, including bone health. Poor vitamin D status is a common but underrecognized problem that predisposes the military population to stress fracture and completed fracture. This has significant implications for force health protection, warfighter readiness, attrition, and cost. Despite this, vitamin D deficiency is still underdiagnosed and undertreated in the military. This is a major hindrance to military readiness and one that could easily be modified with awareness, prevention, and early treatment. In this commentary, we review the literature on vitamin D deficiency and critically examine the current status of policies and clinical practice related to vitamin D in the military health system. We offer several practical recommendations to increase awareness and readiness while decreasing musculoskeletal injury and the associated costs.

BackgroundThe objective of this study was to evaluate sex differences in the incidence and risk of ankle-foot complex (AFC) stress fractures among U.S. military personnel, which could assist in developing management strategies as females assume a greater role in U.S. military operations.MethodsThe Defense Medical Epidemiological Database was used to identify all diagnosed AFC stress fractures in military personnel from 2006 to 2015. Cumulative incidence of AFC stress fractures was calculated and compared by year, service branch, and military rank. Sex differences in the risk of AFC stress fractures by occupation were examined, and integrated (i.e., male and female) occupations were compared with non-integrated (i.e., male-only) occupations.ResultsA total of 43,990 AFC stress fractures were identified. The overall incidence rate was 2.76 per 1,000 person-years for males and 5.78 per 1,000 person-years for females. Females consistently had higher incidence of AFC stress fractures across all subgroups, particularly among enlisted personnel. Female enlisted service members had the highest risk of AFC stress fractures in aviation [relative risk (RR) = 5.74; 95% confidence interval [CI] 4.80–6.87] and artillery/gunnery (RR = 5.15; 95% CI 4.62–5.75) occupations. Females in integrated occupations had significantly higher rates of AFC stress fractures than males in both integrated and non-integrated occupations (i.e., special forces, infantry, and mechanized/armor).ConclusionsFemales in the U.S. military have a higher risk of AFC stress fractures than males. As integration of females into previously sex-restricted occupations continues, focused prevention efforts may be needed to reduce injury burden and maximize medical readiness.

Background: The preferred patient-reported outcome measure for the assessment of shoulder conditions continues to evolve. Previous studies correlating the Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive tests (CATs) to the American Shoulder and Elbow Surgeons (ASES) score have focused on a singular domain (pain or physical function) but have not evaluated the combined domains of pain and physical function that compose the ASES score. Additionally, previous studies have not provided a multivariable prediction tool to convert PROMIS scores to more familiar legacy scores. Purpose: To establish a valid predictive model of ASES scores using a nonlinear combination of PROMIS domains for physical function and pain. Study Design: Cohort study (Diagnosis); Level of evidence, 3. Methods: The Military Orthopaedics Tracking Injuries and Outcomes Network (MOTION) database is a prospectively collected repository of patient-reported outcomes and intraoperative variables. Patients in MOTION research who underwent shoulder surgery and completed the ASES, PROMIS Physical Function, and PROMIS Pain Interference at varying time points were included in the present analysis. Nonlinear multivariable predictive models were created to establish an ASES index score and then validated using “leave 1 out” techniques and minimal clinically important difference /substantial clinical benefit (MCID/SCB) analysis. Results: A total of 909 patients completed the ASES, PROMIS Physical Function, and PROMIS Pain Interference at presurgery, 6 weeks, 6 months, and 1 year after surgery, providing 1502 complete observations. The PROMIS CAT predictive model was strongly validated to predict the ASES (Pearson coefficient = 0.76-0.78; R2 = 0.57-0.62; root mean square error = 13.3-14.1). The MCID/SCB for the ASES was 21.7, and the best ASES index MCID/SCB was 19.4, suggesting that the derived ASES index is effective and can reliably re-create ASES scores. Conclusion: The PROMIS CAT predictive models are able to approximate the ASES score within 13 to 14 points, which is 7 points more accurate than the ASES MCID/SCB derived from the sample. Our ASES index algorithm, which is freely available online ( https://osf.io/ctmnd/ ), has a lower MCID/SCB than the ASES itself. This algorithm can be used to decrease patient survey burden by 11 questions and provide a reliable ASES analog to clinicians.

Introduction: First metatarsal phalangeal joint (MTPJ) arthroplasty has a high failure rate due to aseptic loosening, which leads to bone loss. The salvage procedure is conversion to an arthrodesis, but bone loss can make obtaining screw fixation difficult. Herein, we report a unique case of revision first-metatarsal arthrodesis without the use of hardware after a failed arthroplasty. Case Report: A 60-year-old women presented to us with first MTPJ pain in the setting of failed arthroplasty. We performed an arthrodesis; however, intraoperatively, hardware fixation could not be obtained due to bone loss. We utilized allograft bone struts to maintain first ray length and to hold the correct hallux position during arthrodesis maturation. Conclusion: Bone loss is a frequently encountered problem in revision surgery to a first MTPJ arthrodesis. An arthrodesis can be obtained without the use of hardware in scenarios where bone loss precludes screw fixation. Keywords: Hallux rigidus, revision, bone loss, arthrodesis

BACKGROUND Medical device recalls have increased in the previous two decades. Orthopedic devices are estimated to constitute 12% of all medical devices recalled. Medical devices enter the market via the Food and Drug Administration's (FDA's) premarket approval (PMA) or 510(k) pathways. This article evaluates orthopedic hip device recalls between Jan. 1, 2007, and Dec. 31, 2017. We hypothesized that the 510(k) approval process would have substantially higher recall rates for defective devices. METHODS The FDA's device recall database was queried for all orthopedic hip devices from Jan. 1, 2007, to Dec. 31, 2017. Each recall included product description, recall number, device class, date of recall posting, date of recall termination, manufacturer, FDA-determined cause for recall, number of recalled units, distribution, product classification, and method of approval [510(k), PMA, or unspecified]. RESULTS In total, 774 orthopedic hip devices were recalled between Jan. 1, 2007, and Dec. 31, 2017. The 510(k) approval process constituted 85% of hip device recalls. The most common FDA-determined cause of hip device recalls was device design, which constituted 37% of 510(k)-approved device recalls but only 6% of PMA-approved device recalls. The most recalled hip devices were hip prostheses. Orthopedic hip device recalls have shown a decrease of about 10 recalls per year during the 11-year period of analysis. CONCLUSION Devices approved through the 510(k) process, compared with the PMA process, were more likely to be recalled for design defects. Although device design is the most common reason for device recall, many recalls are due to suboptimally standardized processes (e.g., packaging, process controls, device labeling). Overall, orthopedic hip device recalls decreased during the period of analysis (2007-17).

We present a unique case of chronic deltoid ligament disruption in a 34-year-old high-level military operator with a 12-month history of acute-onset medial ankle pain. Magnetic resonance imaging showed an isolated chronic disruption of the superficial and deep deltoid ligament. The patient was managed operatively with a semitendinosus allograft. No complications were observed during the intra- or perioperative periods. At 12-month follow-up, the patient reported near-complete pain resolution and was able to return to unrestricted active duty. Use of allograft ligamentous reconstruction of the deltoid ligament in a highly active soldier was successful, allowing return to unrestricted active duty.

Category: Ankle; Bunion; Hindfoot; Lesser Toes; Midfoot/Forefoot Introduction/Purpose: There is a growing trend to perform surgical procedures at freestanding ambulatory surgical centers. No literature exists evaluating the rate of adverse events and overall safety of foot and ankle outpatient surgeries at a freestanding ambulatory surgery center (ASC). Methods: A retrospective review of all foot and ankle cases performed over a two year period at a single freestanding ASC. A total of 313 cases were performed. Adverse events are state-reported events that cause harm or lead to additional treatment. Using state-reported adverse events criteria and previous literature from hand and upper-extremity cases, we categorized our adverse events into seven categories: 1) infection requiring intravenous abx or return to the operating room, 2) postoperative transfer to a hospital, 3) wrong-site surgery, 4) retention of a foreign object, 5) postoperative symptomatic thromboembolism (DVT), 6) medication error, and 7) bleeding complications. Results: The overall rate of adverse events was 3.5% with 11 events identified over the two year period. There were a total of 10 infections and 1 symptomatic DVT. There were no cases that resulted in transfer to a hospital, hospital admission after discharge, medication error, bleeding complications, wrong-site procedures, or retained foreign bodies. Conclusion: Outpatient foot and ankle procedures are not without complications, but the overall rate of complications postoperatively is farly low (3.5%). Overall, foot and ankle surgeries can be performed safely in an outpatient setting at an ASC.

Introduction The medical device industry has grown substantially in recent years. There is limited research examining orthopedic subspecialties and the recall of orthopedic devices. We hypothesize that knee arthroplasty devices cleared through the Food and Drug Administration (FDA) 510(k)-notification process would have a higher recall rate than the premarket approval (PMA) process. Methods The FDA database was thoroughly queried for all knee arthroplasty surgical devices from January 1, 2007 through December 31, 2017. Recalled devices were analyzed by manufacturer, type of implant, recall class, manufacturer-determined reason, FDA-determined reason, quantity affected, submission type, and distribution within the United States or internationally. Results Out of over 30,000 medical devices on the market, a total of 300 knee arthroplasty devices from 18 different companies were recalled during the time frame of this study. Tibial components accounted for 35.33% of devices, polyethylene implants for 38.67%, and femoral components for 15%. The most common reason for recall was device design (n = 134, 44.67%), followed by process control (n = 32, 10.67%). Of the 300 knee arthroplasty devices recalled, 267 (89.0%) were cleared through the 510(k) premarket notification process and 33 (11.0%) devices were approved through the PMA process. Conclusions A larger proportion of knee arthroplasty surgical devices cleared through the 510(k) process were recalled compared to implants approved through the stricter PMA process. Changing the 510(k) process may enable manufacturers to improve upon the safety of their devices.

We present a unique case of chronic peroneal tendon dislocation in a 47-year-old active duty military member with a 2-mo history of acute onset lateral ankle pain due to sports injury. Magnetic resonance imaging revealed superficial peroneal retinaculum (SPR) disruption, a flattened retrofibular groove, dislocation of the peroneus longus tendon, and a tear of the peroneus brevis tendon. The patient was managed operatively with fibular groove deepening, SPR reconstruction, peroneus brevis debridement, and peroneus longus tubulurization. No complications were observed during the intra- or perioperative periods. At their 3-mo follow-up, the patient reported near complete resolution of pain and the ability to ambulate without any brace or support. He returned to running and was able to deploy fit for full duty 4.5 mo from injury.

Haglund’s deformity is a common cause of foot pain, with high success rates of surgical intervention. Because early weightbearing rehabilitation correlates with better surgical results, the integrity of anchors employed in these surgeries needs to be evaluated for proper fixation strength, leading to improved postoperative outcomes. The ultrasonically interdigitated anchor is a biodegradable suture anchor that is melted into bony trabeculae using ultrasound, leaving a small biological footprint and less interference on computed tomography and magnetic resonance imaging scans, without loss of fixation strength. We performed a review of 44 patients aged 26 to 84 years treated with either ultrasonically interdigitated anchors or fully threaded titanium anchors during Haglund’s deformity excision. Overall, 7 of 14 patients who received an ultrasonically interdigitated anchor reported raw PROMIS (Patient-Reported Outcomes Measurement Information System) scores averaging 14.3, with an average return to ambulation time of 4.2 weeks. Fifteen of 30 patients receiving a fully threaded titanium anchor reported raw PROMIS scores averaging 9.7, with an average return to ambulation time of 3.5 weeks. We found little difference between the outcomes between the 2 anchors and no massive failures or infections in either group, implying that ultrasonically interdigitated anchors are a viable option for Achilles tendon reattachment during Haglund’s deformity repair surgery.

Background This study evaluates the safety of foot and ankle outpatient surgeries at a freestanding ambulatory surgery centers. Methods A total of 1352 cases were evaluated for adverse events in a retrospective review of all foot and ankle cases performed over a 5-year period at a single center. Results The rate of adverse events was 2.3%, with 31 identified over the 5-year period (23 infections, 5 symptomatic thromboembolisms, 3 postoperative hospital transfers). Discussion The rate of postoperative adverse events in outpatient foot and ankle procedures is low. These surgeries can be performed safely in an outpatient setting at an ASC. Level of evidence Level IV, Case Series.

Background. The goal of this systematic review is to determine the most commonly used outcome measurement tools used by foot and ankle specialists and determine their limitations, such as whether they are validated, have floor/ceiling effects, and so on. Methods. A literature search was conducted to identify primary publications between January 1, 2012 and July 1, 2017 that concern care of the foot and ankle and use any established grading criteria to evaluate patients. Results. In 669 publications, 76 scoring systems were used. The 10 most common were American Orthopaedic Foot and Ankle Score (AOFAS), visual analog scale (VAS), Short Form–36 (SF-36), Foot Function Index (FFI), Foot and Ankle Outcome Score (FAOS), Foot and Ankle Ability Measure (FAAM), SF-12, Short Musculoskeletal Function Assessment (SMFA), Ankle Osteoarthritis Scale (AOS), and Foot and Ankle Disability Index (FADI). AOFAS was used in 393 articles, VAS in 308, and SF-36 in 133 publications. AOFAS, VAS, and SF-36 were used to evaluate 23,352, 20,759, and 13,184 patients respectively. AOFAS and VAS were used simultaneously in 172 publications. Conclusion. While there are many different scoring systems available for foot and ankle specialists to use to assess or demonstrate the effectiveness of treatments, the AOFAS, while it is an unvalidated scoring system, is the most commonly used scoring system in this review. Clinical Relevance. This review presents data about commonly used patient reported outcomes systems in foot and ankle surgery.Levels of Evidence: Level III: Systematic review.

Category: Ethics Introduction/Purpose: The objective of our study was to analyze COI nondisclosure for US based research articles that were published to three prevalent orthopaedic journals from the beginning of 2014 to the end of 2016. Methods: All US-based research articles published to FAI, JBJS, and JOA from the beginning of 2014 to the end of 2016 were reviewed. COI disclosure sections were analyzed to determine if a disclosure was made for first and/or last authors. Authors disclosing any financial relationship involving employment, royalties/licensing, speaking, and consulting fees were recorded as having disclosed a potential COI. First and last authors were then searched for using CMS Open Payments search tool to determine if they had received any of the aforementioned payment types. To determine if a COI nondisclosure (disclosure discrepancy) was present, an author’s disclosure statement for a published article was compared to CMS Open Payments data from the year prior to publication of the article. We used CMS data from the year prior to a publication to account for the time it takes to construct a paper and have it published. Results: Across all journals and years, we obtained disclosure accuracy data for 3,465 total first and last authors publishing 1,770 research articles. Within this sample, 7.1% (245/3,465) of the authors had a recorded undisclosed conflict-of-interest and 13.2% (233/1,770) of articles had a first and/or last author with an undisclosed potential conflict-of-interest. When looking at each journal individually over the three-year period, FAI contained the highest percentage of authors with undisclosed COI’s (42.3%), JBJS contained the lowest percent of authors with an undisclosed COI (4.6%), and JOA had an intermediate amount of authors with an undisclosed COI (7.0%). Conclusion: Discrepancies between payment disclosures made by authors and those published in the CMS database were present in all three journals reviewed in this study. The percentage of articles containing an author with a disclosure discrepancy varies widely between these journals. However, when analyzing the percentage of disclosure discrepancies by year, no trend was found.

The Centers for MedicareMedicaid Services (CMS) Open Payments public database, resulting from the Physician Payments Sunshine Act of 2010, was designed to increase transparency of physicians' financial relationships with pharmaceutical manufacturers. We compared physician-reported conflict-of-interest (COI) disclosures in journal articles with this database to determine any discrepancies in physician-reported disclosures.COIs reported by authors from 2014 through 2016 were analyzed in 3 journals: FootAnkle International (FAI), The Journal of BoneJoint Surgery (JBJS), and The Journal of Arthroplasty (JOA). Payment information in the CMS Open Payments database was cross-referenced with each author's disclosure statement to determine if a disclosure discrepancy was present.We reviewed 3,465 authorship positions (1,932 unique authors) in 1,770 articles. Within this sample, 7.1% of authorships had a recorded undisclosed COI (disclosure discrepancy), and 13.2% of articles had first and/or last authors with a disclosure discrepancy. Additionally, we saw a great variation in the percentage of authorships with disclosure discrepancies among the journals (JBJS, 2.3%; JOA, 3.6%; and FAI, 23.7%).Discrepancies exist between payment disclosures made by authors and those published in the CMS Open Payments database. Although the percentage of articles with these discrepancies varies widely among the journals that were analyzed in this study, no trend was found when analyzing the number of discrepancies over the 3-year period.COI disclosures are important for the interpretation of study results and need to be accurately reported. However, COI disclosure criteria vary among orthopaedic journals, causing uncertainty regarding which conflicts should be disclosed.

Background: Hallux valgus has been associated with a widened forefoot. Most surgical procedures for the correction of hallux valgus have the potential to reduce forefoot width. Success after hallux valgus surgery is correlated with relief of toe pain in conventional shoes and improvement in the appearance of the foot. Therefore, reduction in forefoot width, referred to as metatarsal span (MS), likely correlates with both criteria and may be a reliable radiographic indicator of success after hallux valgus surgery. Methods: Preoperative and postoperative radiographs of 52 patients who underwent correction of hallux valgus with a distal Chevron osteotomy and Akin osteotomy were evaluated by 4 observers. The observers measured the hallux valgus angle (HVA), the intermetatarsal first and second angle (IMA), and the MS. Results: Preoperative HVA ranged from 14° to 48°, IMA ranged from 6° to 25°, and MS ranged from 74.2 to 110.6 mm. The average HVA improvement was 19.4°, IMA improvement was 6.7°, and MS reduction was 8.7 mm. No correlation was identified with regard to correction of the HVA or IMA to MS. Conclusion: Digital radiographic linear measurements were easily and reliably made. Therefore, linear measurements as described in this article can be used as a tool to evaluate if clinical outcomes correlate with reduction of MS. A distal Chevron with an Akin osteotomy has the potential to reduce forefoot width. Levels of Evidence: Level IV: Case series

Category: Total Ankle Arthroplasty Introduction/Purpose: Although demand for total ankle arthroplasty (TAA) is increasing, access to high-volume TAA surgeons may vary in different geographic regions. Given that low-volume TAA surgeons have demonstrated higher revision rates compared to higher-volume surgeons, access to these high-volume centers is a matter of patient and public health interest. The recent public release of the Medicare Provider Utilization and Payment Public Use File (MPUP-PUF) now allows for identification of individual providers who perform specific procedures. This study analyzed surgeon prevalence, distribution and factors that correlate with higher or lower high-volume surgeon population in metropolitan areas. Methods: The MPUP-PUF was reviewed for the 2012-2015 calendar years and data were extracted for all physicians who performed a minimum of eleven TAA procedures among traditional Medicare patients. These physicians were grouped into major metropolitan areas (population of one million or more). Average reimbursement, number of high-volume TAA surgeons and number of total procedures were calculated per major metropolitan area. The presence of an American Orthopaedic Foot and Ankle Society (AOFAS) fellowship and mean geographic reimbursement were analyzed for correlation with number of high- volume TAA surgeons. Results: The MPUP-PUF for 2012 to 2015 included 58 unique surgeons who performed a minimum of 11 TAA procedures in any of those calendar years, with a combined total 2,281 Medicare TAA procedures. Of these surgeons, 81% practice within major metropolitan areas with population greater than one million. Distribution among major metropolitan areas is highly unequal and higher numbers of surgeons are present in cities with an AOFAS fellowship. Conclusion: Access to high-volume ankle replacement surgeons among the Medicare population is lacking in multiple major metropolitan areas in the United States due to the uneven distribution of these surgeons. This method of analysis allows for opportunities to target training programs as well as placement of physicians to ensure access to high-volume ankle arthroplasty surgeons.

Case A 33-year-old woman with Glanzmann thrombasthenia presented to us with a distal tibia nonunion. We attempted to treat her with a multiplanar ring external fixator, but the patient was unable to tolerate the correction, so we resorted to a tibiotalocalcaneal fusion. Hemostasis was difficult to achieve despite the use of antithrombinolytics, factor VII, and platelet transfusions. Conclusion Bleeding can be difficult to control in patients with Glanzmann thrombasthenia. However, overaggressive preadministration of antithrombinolytics should be avoided because it may have adverse effects such as acrocyanosis. The presence of thrombasthenia does not seem to affect the success of arthrodesis.

Background: Inversion ankle injuries are extremely common, sometimes causing injury to the peroneus brevis tendon. If more than 50% of the tendon is injured, it oftentimes requires tenodesis to the adjacent peroneus longus tendon. Both Pulvertaft (PT) and side-to-side (SS) techniques have been used for joining the 2 tendons. The purpose of this study was to compare the strength and stiffness of these 2 techniques. Methods: Five matched pairs of cadaver ankle specimens were randomized to receive either an SS or PT tenodesis of the peroneus brevis to longus tendons. Following the tenodesis, the specimens were tested for failure load, displacement, energy absorbed at failure, and peak load. Stiffness was also calculated. Paired t tests were performed to detect differences between the 2 conditions. Results: There were no statistically significant differences between the SS and PT tenodesis for any of the metrics measured. For stiffness, the techniques were very similar (SS = 10.14 [4.35], PT = 12.85 [1.72]). Conclusion: There is no difference in failure load, displacement, energy absorbed at failure, peak load or stiffness between the PT and SS techniques for peroneal tenodesis. Level of Evidence: Level V, cadaver study.

Introduction Orthopaedic devices represent 12% of all medical device recalls. Products are approved through pre-market approval (PMA) or the 510(k) premarket notification process. No previous evaluation was found in the literature evaluating foot and ankle device recalls. The field of foot and ankle subspecialty has seen a rapid growth in innovation related to implants in recent years. Methods The Food and Drug Administration (FDA) Device Recall database was evaluated for all foot and ankle devices from 2007 through 2017 for the manufacturer, process of approval, type of implant, recall class, dates of initiation and termination of the recall, manufacturer determined reason, quantity affected, and distribution within the United States or internationally. Results A total of 161 products from 33 companies were identified with 158 (98.1%) approved through the 510(k) process. The most common reason for device recall was due to the device breaking intraoperatively or postoperatively. The average length of the recall was 487.5 days. Conclusions Device recall is not an uncommon event with the majority of products approved through the less demanding 510(k) process.

Lisfranc injuries are typically treated in the acute setting with open reduction and internal fixation (ORIF). The type of hardware that provides the best fixation for these injuries has not been definitively determined. Recently, dorsal bridge plating has increased in popularity. We report a case of partial extensor hallucis longus (EHL) injury after dorsal bridge plate fixation of a Lisfranc injury. The patient was successfully treated with hardware removal, tendon debridement, and tubularization. This case highlights a potential complication of dorsal bridge plating in the treatment of Lisfranc injuries.

Background The predictors of erroneous publication reporting among orthopaedic surgery residency applicants have not been established. Methods A retrospective analysis of the reported scholarly activity of candidates who applied to our orthopaedic surgery department for a first-year residency position in 2017 was conducted to determine the incidence of scientific publication misrepresentation and analyze its association with pre-residency criteria. Results Out of 510 candidates, 264 (51.8%) applicants included accepted, in-press, or published scholarly activity on their resumes. The incidence of misrepresentation was 20.5%, and did not differ statistically based on the candidates’ academic performance (United States Medical Licensing Examination – USMLE – steps 1 and 2 scores), Alpha Omega Alpha (AOA) membership, immigration status, or or additional academic degrees (p > 0.05). Conclusions Misrepresentation is a persistent problem among residency training program applicants, and did not correlate with an applicant's academic performance, AOA membership, immigration status, or additional advanced academic degrees.

Background. Residency programs use the annual Orthopaedic In-Training Examination (OITE) prepared by the American Academy of Orthopaedic Surgeons (AAOS) to monitor resident progress and prepare them for the part 1 of the American Board of Orthopaedic Surgeons (ABOS) Certifying Examination. The purpose of this study was to determine resources residents currently use to prepare for the OITE and also to learn about their perception of training they receive in the foot and ankle subspecialty in their program and their interest in foot and ankle fellowship after residency. Methods. An anonymous survey was sent to both allopathic programs and osteopathic residents to learn what resources residents used to study for the OITE, preparatory question sets, on-call resources, their perception on training received in foot and ankle surgery, and their intent to pursue fellowship training. Results. A total of 130 residents participated in the survey. The majority of residents in allopathic and osteopathic residencies used Orthobullets (OB) to prepare for the OITE and use this resource while on-call. Most residents also used OB question sets to study along with the AAOS self-assessment examinations. In total, 43.2% of osteopathic residents felt they did not get enough exposure to foot and ankle subspecialty while in training, in contrast to 31.2% of allopathic residents. A total of 35% of all orthopaedic surgery residents felt they lacked enough exposure to foot and ankle orthopaedic surgery. Only 7 residents (6%, 6 allopathic, 1 osteopathic) intended to pursue a foot and ankle fellowship following graduation. Conclusion. Online resources such as OB continue to be frequently used by residents for preparation for the OITE. Greater than one-third of orthopaedic residents feel they do not get enough exposure to foot and ankle orthopaedic surgery. Improvement in this area could be helped by continued endeavors from the American Orthopaedic Foot and Ankle Society such as the Visiting Professor Program and Resident Scholarship Program.

Background: Diagnosis of distal tibiofibular syndesmotic injuries includes assessment of radiographs; however, there exist no agreed on standard diagnostic criteria. Previous studies lack consistency with radiographic evaluation methods. The dynamic nature of the ankle joint supports analyzing anatomical parameters using weight-bearing films to assess for tibiofibular syndesmotic integrity. Methods: Weight-bearing tibiofibular syndesmosis radiographs of 39 male and 40 female patients were retrospectively analyzed by 3 investigators, at different levels of orthopaedic training. Measurements 1 cm above the tibial plafond for the anterior tibiofibular overlap (TFO) and tibiofibular clear space (TCS) were recorded and standardized by the fibular width (FW) at 2 time points. Data were compared to check for agreement between the sets of measurements for each rater and agreement between investigators, and to ascertain underlying gender differences. Results: There was good intraobserver correlation (intraclass correlation coefficient [ICC] > 0.90) among investigators for each parameter. A significant difference in the TFO was noted between genders (P < .05). We establish the following radiographic (anteroposterior view) parameters for an intact syndesmosis: male patients, TCS 9.29 mm or TFO/FW > 57%; female patients, TCS 7.41 mm or TFO/FW >51%. Conclusions: Our study provides a more objective approach by utilizing weight-bearing radiographs and performing all measurements 1 cm above the tibial plafond. Levels of Evidence: Level IV

Introduction The impact of the interview date on matching in orthopaedic surgery residency is unknown. Materials and methods A retrospective review of interviewed applicants for a first-year orthopaedic surgery residency was conducted to determine the likelihood of matching based on being interviewed early versus late at our program. The United States Medical Licensing Examination (USMLE) scores were compared between early and late interviewees. Results Between 2012 and 2016, 316 candidates interviewed for residency positions. Twenty matched at our program and 230 at other institutions. No difference existed in USMLE scores. Late interviewees had significantly higher chances of matching at our center, but not nationwide in orthopaedic surgery (p = 0.025 and p = 0.58, respectively). Conclusion Later applicant interview was associated with greater chance of matching at our institution, but did not impact the candidate's ability to match in orthopaedic surgery at other programs.

Synovial chondromatosis of the ankle is rare and sparsely documented. Traditional surgical intervention is open loose body excision and synovectomy. Upon literature review, only two other cases were found to be managed arthroscopically. We report a case of synovial chondromatosis in a 54-year-old man leading to pain and limited range of motion of his ankle. This unique case of extensive nodule formation was treated via a three-port arthroscopic approach. Removal of loose bodies and synovectomy were successfully performed arthroscopically. A total of 76 loose bodies were removed and synovectomy performed using a 3.5 mm diameter full radius shaver. This case demonstrates that a three-port arthroscopic approach can provide adequate treatment while maintaining the superior risk profile inherent to arthroscopic intervention.

Background There is a noticeable lack of studies examining the connection between psychiatric illness and orthopaedic injury. The goal of this study is to determine if a relationship exists between calcaneus fracture and psychiatric illness or use of psychotropic medication. Methods A retrospective review was undertaken of calcaneus fracture patients at our institution from January 2011 through January 2014, and those with a diagnosis of psychiatric illness or history of psychotropic medication usage were identified. Medication records were analyzed along with medical histories taken during the initial encounter. If the patient was admitted, hospital notes for the hospitalization were reviewed to determine if any information was missed during the initial encounter. The date of injury, age, sex, insurance status at the time of initial encounter, psychiatric diagnoses or psychotropic medication use, and mechanism of injury were recorded. Any specific psychiatric diagnoses were collected from the patient charts, as was the presence of any specific prescribed psychotropic medications. After completion of the data collection, an attending psychiatrist verified the recorded data to ensure an accurate psychiatric assessment. Results A total of 85 calcaneus fractures met the inclusion criteria. In the population, there were 71 males and 14 females. The average age of the patients was 41.74 years, with 24% of patients having a diagnosis of psychiatric illness at the time of injury. The relative risk of a psychiatric illness in males compared to females was 0.31 (p = 0.009) while the relative risk of using psychotropic medication in males compared to females was 0.17 (p = 0.0007). Males were less likely to undergo operative intervention than females (p = 0.0001). The average age of a patient who either had a diagnosis or took medication for a psychiatric illness was 48.4 years, as compared to 39.7 years in those who did not (p = 0.014). Conclusion Males were less likely to have a psychiatric illness or be currently treated with psychotropic medications. A dedicated review of psychiatric history and prior medication may be useful during preoperative, perioperative, and postoperative treatment planning. Level of Clinical Evidence: 4.
