RESUMEN
Tri-plane corrective Lapidus surgery has been described as advantageous with respect to its anatomic basis and outcomes. Because the procedure has been broadly publicized, changes in overall Lapidus procedure rates due to increased numbers of patients opting for the tri-plane approach could have occurred. Data supporting this possibility appears lacking. We employed official personnel and health records of the total active-duty US military to conduct a retrospective cohort study of Lapidus surgery rates before and after the advent of the tri-plane corrective Lapidus procedure. Least-squares and locally-weighted scatterplot smoother regression functions were used to confirm time trends. Sociodemographic and occupational traits of Lapidus patients were compared using 2-sided t tests and chi square tests. Lapidus surgery rates among hallux valgus patients decreased during 2014 to 2016 and increased during 2017 to 2021. While multiple factors might explain these trends, they coincide with the advent of and advocacy for tri-plane Lapidus surgery. The results support the possibility that its rise influenced overall Lapidus rates in this population. As these findings represent limited evidence of such an influence, further research is required to confirm a causal link. If such a link is found, and if the ongoing research suggests that superior outcomes are associated with tri-plane Lapidus surgery, substantial implications could exist for this population. Benefits might include enhanced medical readiness due to the importance of lower extremity function during military duties. Additional research is needed to confirm the impact of the procedure and to determine whether Lapidus surgery rate patterns in civilian populations mirror these findings.

BACKGROUND: When the symptoms of hallux valgus persist despite nonoperative management, surgical intervention may be considered to improve pain and restore function. Although most patients return to full or near-full activity after surgery, this is not always the case in higher-demand populations. In fact, little is known about the likelihood of a military servicemember returning to running or military duty, which is analogous to a recreationally active adult, after hallux valgus correction. QUESTIONS/PURPOSES: (1) What percentage of military servicemembers are able to return to full duty, including the ability to run 1.5 to 2 miles, 1 year after hallux valgus surgery? (2) What demographic, radiographic, and surgical variables are associated with an increased likelihood of return to full duty? METHODS: This was a retrospective study of all military servicemembers who underwent surgical correction of hallux valgus deformities at a single tertiary institution from January 2005 to December 2016. We considered military servicemembers who were treated by four fellowship-trained foot and ankle orthopaedic surgeons and who had at least 1 year time-in-service remaining as potentially eligible. A total of 229 people underwent hallux valgus correction during this timeframe, but only 28% (64 of 229) of patients remained eligible: 41% (93 of 229) were excluded because they were not military members, 28% (64 of 229) were ineligible because they had less than 1 year remaining in service, 2% (4 of 229) were excluded because of prior surgery on the ipsilateral extremity, and 2% (4 of 2292) had an incomplete dataset. Interventions included a modified McBride procedure (9% [6 of 64]), distal metatarsal osteotomies (51% [33 of 64]), proximal metatarsal osteotomies (13% [8 of 64]), and Lapidus procedures (27% [17 of 64]). No bilateral procedures were performed. The mean age of our patients was 40 ± 10 years, and the mean BMI was 28 ± 9 kg/m 2 . In addition, 23% (15 of 64) of patients were nicotine users, 38% (24 of 64) were officers, and 45% (29 of 64) were women. The indication for surgery was functionally limiting pain that persisted despite 4 to 6 months of activity modifications, accommodative footwear, and orthotics. Cosmesis was not an indication for surgery. Before surgery, all patients were unable to complete a 1.5- to 2-mile timed run due to pain. The primary outcome measure was the proportion of patients who returned to full duty, which was defined as the ability to complete a 1.5-mile to 2-mile run for a military fitness test in a fixed time allotment, which varies by age and gender, and the ability to perform military-specific physical tasks at 1 year postoperatively. A secondary analysis according to demographic, radiographic, and surgical variables sought to determine any differences between those who did and did not return to full duty; this was assessed using univariable statistical comparisons at a p value of less than 0.01. RESULTS: A total of 28% (18 of 64) of patients who underwent surgery returned to full duty by 1 year after surgery as determined by the ability to complete a time-allotted 1.5- to 2-mile fitness test run. Of the factors we explored, we did not identify any variables associated with return to full duty. We note that our analysis may have been underpowered to detect differences among factors that could be clinically important, like BMI, age, and comparisons of officers versus enlisted servicemembers. CONCLUSION: Although this study analyzed the functional outcomes of a group of military servicemembers after hallux valgus correction, we believe our findings may also apply to recreationally active adults in the general population. Only a minority of military servicemembers (28% [18 of 64]) returned to duty 1 year after hallux valgus correction, as determined by the ability to complete a timed 1.5- to 2-mile run. We believe surgeons can use the findings of this study to set realistic expectations for recreationally active adults, particularly runners, after hallux valgus correction. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: Despite the literature on acute Achilles tendon ruptures, there remains a lack of consensus regarding the optimal treatment. The purpose of this survey study was to investigate treatment preferences among Army orthopaedic surgeons when presented with a standardized case of an acute Achilles rupture and determine if surgeon factors correlated with treatment preference. METHODS: A hypothetical case of a 37-year-old male with history, physical exam, and imaging consistent with an Achilles rupture was sent to board-certified Army orthopaedic surgeons to determine their preferred management. Demographic data was collected to include: practice setting, years from residency graduation, and completion of fellowship. Correlations analyzed between demographics and treatment preferences. RESULTS: Sixty-two surgeons responded. 62% of respondents selected surgical intervention. Of these, 59% chose a traditional open technique. 50% of respondents were general orthopaedic. There was a correlation between fellowship training and operative management (P = 0.042). Within the operative management group there was no statistical difference (P > 0.05) in need for further imaging, technique used, post-operative immobilization, length of immobilization, weight-bearing protocol, and time to release to running. The majority of non-operative responders would splint/cast in plantarflexion or CAM boot with heel lift for < 3 weeks (50%) and keep non-weight bearing for < 4 weeks (63%). Only 38% of respondents would use DVT chemoprophylaxis. CONCLUSION: When provided with a hypothetic case of an acute Achilles tendon rupture, queried Army orthopaedic surgeons would more often treat with a surgical procedure. This difference in treatment is secondary to training, fellowship or other. This propensity of surgical management, likely stems from the highly active population and the desire to return to duty.

The objective of this study was to review the use of liposomal bupivacaine as a multimodal pain management adjunct following hallux valgus surgery. The study was a prospective review of a consecutive series of patients who underwent hallux valgus surgery and received liposomal bupivacaine. From postoperative day (POD) 1 to 4, pain scores, number of narcotic rescue pills used, and adverse events were recorded. Wound complications, narcotic refills, and unscheduled clinic and emergency room (ER) visits or hospital admissions for pain were also recorded. The average pain rating was <3.4 (±2.4) during POD 1 to 4. Four patients (28.6%) reported never experiencing pain (Numeric Rating Scale ≤1). Seventy-one percent used narcotic rescue pills on POD 1. There were no unscheduled office or ER visits or hospital admissions. One adverse event and one wound complication occurred. Liposomal bupivacaine may be a safe and useful adjunct in a multimodal pain regimen for patients undergoing hallux valgus surgery. More rigorous studies are needed to determine its efficacy, safety profile, and cost-effectiveness compared to placebo.

Lower extremity ambulatory assistive devices (LEADs) are important augments that provide mobility and stability when weightbearing is restricted in the setting of injury, surgery, or balance disorders. In order to optimize patient safety and function when prescribing these devices, it is essential for the orthopaedic surgeon to have a firm understanding of their specific indications, proper fitting, energy demand, biomechanical advantages, and potential complications. Comprehension of normal gait cadence, identification of the functional deficit present and knowledge of available options will assist in safely prescribing the proper device. Over the last decade, newer alternatives to traditional LEADs (canes, crutches, walkers) have become available, including the rolling knee scooter and hands-free single crutch. These have been developed to improve mobility and independence; however, it is necessary to appreciate their limitations when prescribing them to patients. This review will provide an update on normal and pathologic gait biomechanics as well as the most common types of LEADs currently available to the orthopaedic surgeon, their indications, important considerations, proper fitting, associated energy expenditure, and complications.

OBJECTIVES: Tibiotalocalcaneal (TTC) nailing in the setting of acute ankle trauma has become increasingly popular. No consensus exists as to whether formal joint preparation is necessary, although there is some concern that residual motion at unprepared joints may lead to implant loosening and/or breakage. The objective of this study was to quantify the proportion of tibiotalar and subtalar articular surface destruction that occurs during reaming for TTC nail fixation. METHODS: Twelve cadaver lower extremities were procured. The specimens were pinned into neutral ankle and hindfoot alignment. A guidewire was inserted under fluoroscopy, followed by a 12-mm opening reamer. The specimens were then dissected, exposing the tibial plafond, talar dome, posterior facet of the talus, and posterior facet of the calcaneus. Images of each joint were obtained, and ImageJ software was used to calculate the total joint surface area and the area of articular destruction. RESULTS: The mean proportion of articular cartilage destruction was 9.3%, 10.3%, 8.9%, and 10.3% for the tibial plafond, talar dome, posterior facets of the talus, and posterior facets of the calcaneus, respectively. No joint destruction was observed in the middle facets of the subtalar joint. CONCLUSIONS: Reaming for TTC nail placement violates approximately 10% of each articular surface of the tibiotalar and subtalar joints. Retention of 90% of the articular surface may allow for residual motion at the joints and therefore potentially substantial stress on the implant. Formal joint preparation for the purposes of achieving fusion during TTC nail placement may be beneficial to prevent implant loosening or breakage.

BACKGROUND: Femoral neck stress fractures (FNSFs) are a unique injury pattern not commonly treated in the civilian trauma population; however, it is particularly high with military trainees engaged in basic combat training. To date, no study has surveyed a population of military orthopedic surgeons on treatment preferences for military service members (SMs) with FNSF. QUESTIONS: We aim to evaluate the extent of clinical equipoise that exists in the management of these injuries, hypothesizing that there would be consensus in the factors dictating surgical and non-surgical intervention for FNSF. PATIENTS AND METHODS: A 27-question survey was created and sent to U.S. military orthopedic surgeon members of the Society of Military Orthopaedic Surgeons. The survey was designed in order to gather the experience among surgeons in treating FNSF and identifying variables that play a role in the treatment algorithm for these patients. In addition, seven detailed, clinical vignettes were presented to further inquire on surgeon treatment preferences. Binomial distribution analysis was used to evaluate for common trends within the surgeon's treatment preferences. RESULTS: Seventy orthopedic surgeons completed the survey, the majority of whom were on active duty status in the U.S. Military (82.86%) and having under 5 years of experience (61.43%). Majority of surgeons elected for a multiple screw construct (92.86%), however the orientation of the multiple screws was dependent on whether the fracture was open or closed. Management for compression-sided FNSF involving ≥50% of the femoral neck width, tension-sided FNSF, and stress fractures demonstrating fracture line progression had consensus for operative management. Respondents agreed upon prophylactic fixation of the contralateral hip if the following factors were involved: Complete fracture (98.57%), compression-sided fracture line >75% (88.57%), compression-sided fracture line >50-75% with hip effusion (88.57%), contralateral tension-sided fracture (87.14%), and compression-sided fracture line >50-75% (84.29%). An FNSF < 50% on the contralateral femoral neck or a hip effusion was indeterminate in surgeons indicating need for prophylactic fixation. Majority of surgeons (77.1%) utilized restricted toe-touch weight-bearing for postoperative mobility restrictions. CONCLUSIONS: Consensus exists for surgical and non-surgical management of FNSF by U.S. military orthopedic surgeons, despite the preponderance of surgeons reporting a low annual volume of FNSF cases treated. However, there are certain aspects in the operative and non-operative management of FNSF that are unanimously adhered to. Specifically, our results demonstrate that there is no clear indication on the management of FNSF when an associated hip effusion is involved. Additionally, the indications for surgically treating contralateral FNSF are unclear. LEVEL OF EVIDENCE: IV.

BACKGROUND: Serial casting has demonstrated efficacy for idiopathic early-onset scoliosis (EOS). Results of casting in nonidiopathic (syndromic and congenital) EOS patients have not previously been well described. METHODS: A total of 53 patients underwent serial casting for EOS from 2005 to 2010 at a single institution. Deformity was classified as idiopathic or nonidiopathic. Diagnosis, time in cast, number of casts, use of bracing, complications, and outcomes were recorded. Radiographic measures included Cobb angle and thoracic height (T1-T12). Thoracic height velocity was calculated and compared with established norms. RESULTS: A total of 36 patients, 19 idiopathic and 17 nonidiopathic (14 syndromic, 3 congenital), completed cast treatment and had >6-month follow-up and were therefore included. Of those, 17% (6/36) experienced resolution of their deformity, 53% (19/26) are currently in braces, and 31% (11/36) had undergone surgery. Surgery occurred on average at age 5.6 years and was delayed by an average of 2.1 years from time of first cast. A 19% complication was observed. There was no statistical difference in the rate of resolution of deformity between idiopathic (5/19) and nonidiopathic (1/17) patients (P=0.182), although there exists a trend toward greater curve correction in idiopathic patients. Surgery occurred in fewer patients (2/19) in the idiopathic group compared with the nonidiopathic group (9/17) (P=0.006). Significant improvements in Cobb angle was observed in the idiopathic group (12.2 degrees) during casting (P=0.003). Nonidiopathic patients did not maintain the correction gained during casting at the time of final follow-up. T1-T12 height increased across all study patients regardless of etiology during the period of casting at similar velocity to established norms of 1.4 cm/y for this age group. CONCLUSIONS: Serial casting offers modest deformity correction in idiopathic deformities compared with nonidiopathic deformities. Thoracic height growth continued throughout the casting period at normal velocity. Serial casting maintained normal longitudinal thoracic growth in all patients with EOS in this cohort. Although many required surgery, the increased thoracic height may have positive implications on ultimate pulmonary function. LEVEL OF EVIDENCE: Therapeutic level III.

BACKGROUND: Although it is generally known that clavicle fractures represent a common injury of the shoulder girdle in the general population, the true incidence in the active duty military population is unknown. Given the implications for such injuries on the ability to perform occupation-specific tasks, determining the incidence in the U.S. military population is worthwhile. The purpose of this study was to determine the incidence of clavicle fractures in the U.S. military and to identify any demographic risk factors for injury. METHODS: We performed a query of the Defense Medical Epidemiology Database with the code from the International Classification of Diseases, Ninth Revision, for clavicle fractures for the years 1999 through 2008. An overall injury incidence was calculated, in addition to multivariate analysis, to determine independent risk factors among the following demographic considerations: sex, race, branch of military service, rank, and age. RESULTS: During the study period, a total of 12,514 clavicle fractures were documented among an at-risk population of 13,770,767 person-years for an incidence rate (IR) of 0.91 per 1,000 person-years in the U.S. Military. Males, when compared with females, were more than twice as likely to sustain a clavicle fracture (IR ratios [IRR], 2.30; 95% confidence intervals [CI], 2.12-2.49). The peak incidence of clavicle fractures occurred in the age groups of <20 and 20 to 24. Compared to black service members, the white service members were associated with significantly higher rate of clavicle fractures (IRR, 2.45; 95% CI, 2.28-2.63). The service members serving in the Marine Corps were associated with a higher IR of clavicle fractures when compared to those in the Navy (IRR, 1.44; 95% CI, 1.35-1.53). Junior enlisted service members were 34% as likely to sustain a clavicle fracture when compared to senior officers (IRR, 1.46; 95% CI, 1.34-1.60 and IRR, 1.12; 95% CI, 0.99-1.28, respectively). CONCLUSIONS: The incidence of clavicle fractures among U.S. military personnel (0.908 per 1,000 person-years) is higher than previous epidemiological reports.

INTRODUCTION: Since January 2002, pre-deployment training of forward resuscitative and surgical units has taken place at the U.S. Army Trauma Training Center (ATTC) in Miami, FL. In June 2019, the 240th Forward Resuscitative Surgical Team (FRST) conducted the first pre-deployment Surgical Readiness Training Exercise (SURGRETE) in San Pedro Sula, Honduras, to allow the team to rehearse in a resource-constrained environment more similar to that expected on deployment. The purpose of this study is to describe and compare the pre-deployment training experiences of the 240th FRST during their SURGRETE in Honduras and ATTC rotation in Miami, FL. MATERIALS AND METHODS: A descriptive analysis of prospectively collected data was performed for surgical cases, trauma resuscitations, and nonsurgical procedures by the 240th FRST over a 2-week SURGRETE in Honduras and 2-week ATTC rotation in Miami, FL. Items accomplished within the Individual Critical Task Lists (ICTLs) of key clinical providers on the team (general surgeon, orthopedic surgeon, emergency medicine physician, and Certified Registered Nurse Anesthetist) were identified and compared to those accomplished at the ATTC. RESULTS: During the SURGRETE in Honduras, 64 surgical cases, 1 trauma resuscitation, 2 Advanced Cardiac Life Support codes, and 213 nonsurgical procedures were performed collectively by the team. During ATTC rotation, the team performed a combined total of 10 surgical cases, 6 trauma resuscitations, and 56 nonsurgical procedures. For each key clinical provider, more of their assigned ICTLs were conducted during the Honduras SURGRETE than during ATTC rotation. The ATTC, however, offered more cases of acute life-threatening trauma. CONCLUSION: Appropriately planned SURGRETEs can provide a concentrated case volume in a resource-constrained setting and challenge the team to consider definitive management algorithms. The cases performed may not necessarily reflect the type and acuity of operations performed in a deployed environment; however, they facilitate repetition of basic skills, team cohesion, and cross-training. The SURGRETE experience could be improved by locating a facility with a trauma-dominant patient population that allows increased autonomy of U.S. physicians.

BACKGROUND: Although most combat-related amputations occur early for unsalvageable injuries, >15% occur late after reconstructive attempts. Predicting which patients will abandon limb salvage in favor of definitive amputation has not been explored. The purpose of this study was to identify factors contributing to late amputation for type III open tibia fractures sustained in combat. METHODS: Operative databases were reviewed to identify all combat-related type III open diaphyseal tibia fractures from March 2003 to September 2007. Patients were categorized based on their definitive treatment: group I, limb salvage; group II, early amputation (<12 weeks postinjury); group III, late amputation (≥ 12 weeks postinjury). Injury, treatment, and complication data were extracted from medical records and compared across groups. RESULTS: We identified 213 consecutive fractures, including 166 (77.9%) treated definitively with limb salvage, 36 (16.9%) with early amputation, and 11 (5.2%) with late amputation. There was no difference in fracture severity among the three groups. Before amputation, group III was more likely to use autograft and bone morphogenic protein (27.3%), compared with group I (4.8%) and group II (0%), and was more likely to undergo rotational flap coverage (45.5%), compared with group II (0%). Group III patients had the highest average number of revision surgeries and rate of deep soft tissue infection and were more likely to have osteomyelitis (54.5%) before amputation compared with group I (13.9%) and group II (16.7%). CONCLUSION: Patients definitively managed with late amputation were more likely to have soft tissue injury requiring flap coverage and have their limb salvage course complicated by infection.

Management of displaced midshaft clavicle fractures in the military, a largely shoulder-bearing population, is controversial. We aimed to report the military-relevant functional outcomes after plate fixation. We performed a nested cross-sectional analysis of active duty service members enrolled in an ongoing multicenter, randomized trial on clavicle plating. For this analysis, we included subjects with 26 months follow-up. Outcome measures included radiographic appearance, physical examination, a military-specific questionnaire, and validated shoulder surveys. Mean follow-up for 28 clavicle fractures was 13 months. Union rate by 12 weeks was 93% (26/28). There was one case of soft tissue irritation requiring hardware removal. At latest follow-up, 75% of patients were satisfied; 68% had mild/no pain; 79% had full range of motion; 75% could perform push-ups; and 21% have deployed. For the majority of active duty personnel, rapid healing, return to military-specific tasks, and satisfaction with outcome are possible after plate fixation of clavicle fractures. However, approximately 25% report some functional limitations at 1 year.

BACKGROUND: Posterior malleolar fractures within a trimalleolar ankle fracture pattern are challenging to manage. Posterior ankle arthroscopy provides a means to assess the intra-articular and syndesmotic reductions, while removing loose bodies. The purpose of this study was to determine the radiographic and patient reported outcomes of posterior arthroscopic reduction and internal fixation (PARIF) in trimalleolar ankle fractures. METHODS: From November 2015 to March 2019, we prospectively enrolled consecutive trimalleolar ankle fractures that underwent PARIF by a single surgeon. Preoperative and postoperative computed tomography (CT) scans were interpreted by 2 blinded musculoskeletal radiologists for articular reduction, syndesmosis congruity, and presence of ossific loose bodies. Patient outcomes were assessed using the Foot and Ankle Disability Index (FADI), American Orthopaedic Foot & Ankle Society (AOFAS) ankle score, Olerud-Molander Ankle Score (OMAS), and visual analog scale (VAS). A total of 28 trimalleolar ankle fractures were treated with PARIF. Mean patient age was 36 years (range, 19-69). RESULTS: Preoperative CT identified 18 intra-articular loose bodies (range, 0-4) in 36% of ankles and 75% (n = 21) syndesmosis incongruity. Postoperative CT scans demonstrated anatomic intra-articular reduction in all fractures, 41.7% (5/12) syndesmosis incongruity without fixation, and 0% (0/9) with suture-button fixation. At mean 2-year follow-up, the results were good to excellent with mean VAS score 1 (range, 0-4), AOFAS score 84 (range, 63-100), FADI 85 (range, 59-100), and OMAS 76 (range, 40-100). CONCLUSION: The PARIF technique for displaced posterior malleolar fractures was effective in achieving anatomic intra-articular reduction, syndesmosis congruity, and intra-articular loose body removal, while safely preserving the soft tissues. LEVEL OF EVIDENCE: Level IV, prospective case series.

BACKGROUND: As the movement toward evidence-based medicine grows and publication rates rise each year, critical analysis of the orthopedic literature has become increasingly important. To aid readers in assessing the scientific quality of published research, Foot & Ankle International (FAI) began assigning levels of evidence to all clinical articles in 2008. The purpose of this study was to analyze trends in the characteristics and levels of evidence of articles published in FAI between 2000 and 2015. METHODS: All articles published in FAI from the years 2000, 2005, 2010, and 2015 were reviewed and categorized into article type (clinical, basic science, review, or technical tip). Each clinical article was assigned a level of evidence (I-V) and study type (prognostic, therapeutic, economic, or diagnostic). Descriptive information was gathered pertaining to country of origin, author credentials, and funding. Statistical analysis was performed using chi-squared tests to detect any trends in levels of evidence and publication characteristics. RESULTS: A total of 647 articles were reviewed. From 2000 to 2015, there was a statistically significant increase in the publication of clinical research articles (70% to 83%; P = .013), while the number of basic science articles decreased (29% to 17%; P = .013). Of the clinical articles, there was a significant increase in therapeutic studies (41% to 58%; P = .003). During the study period, the publication of Level I and II evidence significantly increased (2% to 14%; P = .002). Although Level III and V evidence also increased (65% to 71%, P > .99), this was not found to be statistically significant. Publications originated from a total of 39 countries, with a significant increase in the proportion of international papers (33% to 48%; P = .007) over the study period. The proportion of articles authored by Doctors of Podiatric Medicine (DPMs) during the study period significantly decreased (4% to 2%, P = .035). Finally, the percentage of studies that disclosed the use of outside funding increased during the study period, with reported funding from grants or professional groups rising from 3% to 16% (P < .001) and reported funding from commercial sources rising from 0% to 9% (P = .002). CONCLUSION: The proportion of Level I and II studies published in FAI significantly increased from 2000 to 2015. The publication of clinical research rose, with a majority being therapeutic studies. There was a significant increase in articles published by international authors and a significant decrease in articles published by DPMs. During the same time period, there was a rise in the proportion of articles reporting the use of outside funding, both professional and commercial.
RESUMEN
BACKGROUND: A 9-grid scheme has been integrated into the foot and ankle literature to help clinicians and researchers localize osteochondral lesions of the talus (OLTs). We hypothesized that fellowship-trained orthopedic foot and ankle surgeons would have a high rate of intra/inter-observer reliability when localizing OLTs, therefore validating the scheme. METHODS: We queried our institution's foot and ankle radiographic database for magnetic resonance images with OLTs. Each MRI was reviewed by the senior author, and 2 key images (widest OLT diameter) from each tangential view were copied and combined onto one slide. Fifty consecutive deidentified images of ankles were then sent to 4 practicing fellowship-trained foot and ankle surgeons. Each was asked to identify which zone the OLT was localized within. A radiologist's report served as the control. Statistical analyses were performed using Cohen and Fleiss kappa tests. RESULTS: The reviewers demonstrated majority consensus on 45/50 images with substantial agreement for zones 4 and 6. The interobserver reliability was moderate with a κ = 0.55. The mean intraobserver reliability was substantial, with a κ = 0.79. A musculoskeletal radiologist determined there were 3 lesions in zone 7, 18 lesions in zone 4, and 29 lesions in zone 6. CONCLUSION: This study is the first to critically evaluate the 9-grid scheme and its reliability among orthopedic foot and ankle surgeons. Our study found that the 9-grid scheme is an accurate method of localization for OLTs with high intra- and moderate interobserver reliability between surgeons. LEVEL OF EVIDENCE: Level IV, retrospective diagnostic study.
RESUMEN
BACKGROUND: Weightbearing restrictions following foot and ankle surgery require the use of appropriate assistive devices for nonweightbearing ambulation during the recovery period. Selecting an appropriate assistive device that safely optimizes mobility and participation in daily activities is important to patient compliance and satisfaction. The purpose of this study was to compare physiologic demand, perceived exertion, and patient preference between a hands-free single crutch (HFSC) and standard axillary crutches (SACs) in foot and ankle patients. METHODS: Using 44 preoperative orthopedic foot and ankle patients who had a mean age of 32 (19-51) years, a prospective, randomized, crossover study was performed. The sample consisted of 35 males and 9 females. The mean body mass index (BMI) was 26 (19-36), the mean height was 1.7 m, and the mean weight was 82 kg. Patient data and preactivity heart rate were recorded for all patients, who were then randomized to either an HFSC or SACs. Each patient was randomly assigned to the device they would utilize first using a random number generator. They then crossed over to the other device after vitals returned to within 10% of their baseline heart rate. Every subject completed a 6-minute walk test (6MWT) using both assistive devices in a crossover manner. Immediately following each 6MWT, postactivity heart rate, self-selected walking velocity (SSWV), perceived exertion using the OMNI Rating of Perceived Exertion (OMNI-RPE), and perceived dyspnea using the Modified Borg Dyspnea Scale were obtained. After completing both 6MWTs, patients were asked which assistive device they preferred the most. RESULTS: The HFSC was preferred by 86% of patients. Significantly lower dyspnea scores (2.8 vs 5.3; P < .001), fatigue scores (2.4 vs 5.5; P < .001), preactivity and postactivity change in heart rate (28 vs 46 bpm; P < .001), and mean postactivity heart rate (107 vs 122 bpm; P < .001) were found using the HFSC compared with the SACs. The SAC group trended toward a higher SSWV (0.8 vs 0.77 m/s; P = .08). Those with a BMI greater than 25 also preferred iWALK over SACs (P < .05). Neither group had any falls. Sixty-eight percent of patients complained of axillary/hand pain with the SACs, while 7% complained of proximal leg strap discomfort with the HFSC. CONCLUSION: The results of the current study in our relatively healthy cohort found that foot and ankle patients who were nonweightbearing preferred the HFSC over SACs. They experienced less physiologic demand as well as discomfort and perceived less exertion when using the HFSC compared with SACs. LEVEL OF EVIDENCE: Level II, prospective comparative study.

UNLABELLED: Despite major improvements in surgical technique and implant designs in total ankle arthroplasty (TAA), wound healing complications are still commonly encountered. Not only do these problems delay postoperative recovery and threaten functional outcomes, they also carry an increased risk of progression to deep wound infection, which can jeopardize ultimate retention of the implant. In an effort to reduce the high frequency of wound-related complications after TAA, we have incorporated the use of continuous external tissue expansion (CETE) to augment our closures of the anterior ankle incision. CETE is an innovative technique that is currently being used to aid in the rapid closure of acute and chronic full thickness soft tissue defects, including fasciotomy wounds, high grade open fractures, and chronic foot ulcers. By exploiting the viscoelastic properties of the skin, this technique not only facilitates wound edge approximation of full thickness defects, it also helps take tension off tenuous incisions, thus allowing them to heal and reducing the chance for wound dehiscence. This is the first description of the use of an external tissue expander for the prevention of wound healing complications in the setting of TAA. Since introducing CETE to the closure of our TAA incisions, we have seen a decrease in the number of postoperative wound complications and time to wound healing. Based on our experience, we believe that the use of CETE for the prophylactic management of tenuous surgical incisions, specifically those used in the anterior approach to the ankle during TAA, is both safe and efficacious.

BACKGROUND: An Achilles sleeve avulsion occurs when the tendon ruptures distally from its calcaneal insertion as a continuous "sleeve." This relatively rare injury pattern may not be appreciated until the time of surgery and can be challenging to treat because, unlike a midsubstance rupture, insufficient tendon remains on the calcaneus to allow for end-to-end repair, and unlike a tuberosity avulsion fracture, any bony element avulsed with the tendon is inadequate for internal fixation. This study aimed to highlight the characteristics of Achilles sleeve avulsions and present the outcomes of operative repair using suture anchor fixation. METHODS: A retrospective analysis was conducted on 11 consecutive Achilles tendon sleeve avulsions (10 males, 1 female; mean age 44 years) that underwent operative repair between 2008 and 2014. Patient demographics, injury presentation, and operative details were reviewed. Postoperative outcomes were collected at a mean follow-up of 38.4 (range, 12-83.5) months, including the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot score, visual analog scale (VAS) for pain, plantarflexion strength, patient satisfaction, and complications. RESULTS: Eight patients (72.7%) had preexisting symptoms of insertional Achilles disease. Ten of 11 (90.9%) injuries were sustained during recreational athletic activity. An Achilles sleeve avulsion was recognized preoperatively in 7 of 11 (64%) cases, where lateral ankle radiographs demonstrated a small radiodensity several centimeters proximal to the calcaneal insertion. Intraoperatively, 90.9% of sleeve avulsions had a concomitant Haglund deformity and macroscopic evidence of insertional tendinopathy. All patients healed after suture anchor repair. The average AOFAS score was 92.8 and VAS score was 0.9. Ten patients (90.9%) were completely satisfied. One complication occurred, consisting of delayed wound healing. CONCLUSIONS: Achilles tendon sleeve avulsions predominantly occurred in middle-aged men with preexisting insertional disease, while engaged in athletic activity. Suture anchor fixation, combined with addressing concomitant insertional pathology, was a reliable and safe technique for the operative management of Achilles tendon sleeve avulsions. The majority of patients returned to their preinjury levels of work and recreational activity. LEVEL OF EVIDENCE: Level IV, retrospective case series.
