Category: Midfoot/Forefoot Introduction/Purpose: The Weil osteotomy (WO) is frequently used for treating metatarsalgia and metatarsophalangeal (MTP) instability. Nevertheless, it presents complications, being the floating toe the most frequent one. A modification has been proposed to decrease the beforementioned complication, removing a slice from the osteotomy (modified Weil osteotomy, MWO). Additionally, it has been proposed that stabilizing the toe interphalangeal joints when treating hammer toes may contribute to decrease the floating toe complication, given that all flexors contribute to MTP flexion. The objective of this research is to describe complications and functional score in patients operated with MWO with and without interphalangeal stabilization. Methods: 110 patients (250 toes) treated for metatarsalgia and hammer toe deformity were retrospectively collected and prospectively followed for 66 months (SD 15). 2 groups were studied, 45 adults with isolated MWO and 65 adults with MWO with toe stabilization. Average age 55. Patients with Diabetes, previous surgeries and infections were excluded. LEFS, AOFAS and satisfaction index were recorded. A physical examination looking for floating toe, MTP instability and metatarsalgia was performed. Statistical analysis included logistic regression spearmen correlation test, Mann-Whitney test and student T test. Results: LEFS and AOFAS scores were 70 and 73 respectively, with no differences between patients operated with isolated MWO or with toe stabilization. Satisfaction index average result was “minor reservations”. Floating toe incidence was 24%, with no difference between groups. There was no difference in functional scores and satisfaction index if floating toe was present or absent. There was no correlation between functional scores and satisfaction index. Metatarsalgia was present in 31% of patients, and there is a direct correlation of floating toe occurrence and pain (4 times more chance to have pain). Conclusion: There was no clinical significant consequence of floating toe on LEFS, AOFAS or satisfaction. There was no difference in complication rate, functional scores and patient satisfaction if the interphalangeal joint was fixed or not. Although floating toe didn’t influence on functional scores, it was associated with pain. It can be suggested that the scores utilized were not able to detect the negative influence of floating toe on every patient. The high prevalence of floating toe using the MWO should make us look for additional factors which we may be overlooking when treating metatarsalgia, such as plantar plate damage.

Published: September 2018

Category: Hindfoot Introduction/Purpose: Lateral column lengthening (LCL) is a common procedure for reconstruction of stage II flexible adult acquired flatfoot deformity (AAFD). The recent development of porous titanium wedges for this procedure provides an alternative to allograft and autograft. The purpose of this study was to report radiographic and clinical outcomes achieved with porous titanium wedges in LCL. Methods: A retrospective analysis of 34 feet in 30 patients with AAFD that received porous titanium wedges for LCL from January 2011 – October 2014. Deformity correction was assessed using both radiographic and clinical parameters. Radiographic correction was assessed using the lateral talo-first metatarsal angle, the talonavicular uncoverage percentage, and the first metatarsocuneiform height. The hindfoot valgus angle was also obtained. Results: Patients were followed from a minimum of six months up to 48 months (mean 16.1 months). Patients underwent concomitant procedures including medial displacement calcaneal osteotomy (94.1%), flexor digitorum longus transfer (70.6%), posterior tibial tendon tenolysis (64.7%), gastrocnemius recession (20.6%), and cotton osteotomy (4.9%). Postoperative radiographs demonstrated significant correction in all three radiographic criteria as well as the hindfoot valgus angle compared to their preoperative measurements. There were no cases of nonunion, no wedge migration, no infections, and no patients required removal of hardware. The most common complication was calcaneocuboid joint pain (14.7%). Conclusion: AAFD is a problem with various treatment modalities. Porous titanium wedges in LCL can achieve good radiographic and clinical correction of AAFD with a low rate of nonunion and other complications.

Published: September 2018

Category: Ankle Arthritis Introduction/Purpose: Ankle arthrodesis is commonly performed for patients with end stage ankle arthritis. However, with improvements in long-term outcomes following total ankle arthroplasty it is possible that rates of ankle arthrodesis will decrease as utilization of ankle arthroplasty increases. The purpose of this study is to assess the current and future trends of ankle arthrodesis utilization. Methods: National Inpatient Sample (NIS) data from 1997-2014 was used to identify trends in the utilization of ankle arthrodesis. United States Census Bureau data from 1997-2014 was used to identify historical population data and future population estimates. A linear regression model was created using Mathematica v11.3 to project future demand for ankle arthrodesis. The data was stratified to show past and future trends based on gender and age. Results: The overall utilization rate of ankle arthrodesis remained relatively constant from 5897 procedures in 1997 to 5330 procedures in 2014. The overall demand for ankle arthrodesis is expected to increase slightly by 15 percent with 6141 procedures projected in 2045. Stratified by age groups, the number of procedures is predicted to decrease by 75% in ages 18-44 and 6% in ages 45-64, and predicted to increase by 133% in ages 65-84 by 2045. Stratified by gender, ankle arthrodesis is predicted to increase by 47% in males and decrease by 14% in females in 2045. Conclusion: Based on our projection model, the rate of ankle arthrodesis is predicted to stay relatively stable overall but decrease in younger populations. A projected increase in total ankle arthroplasty will likely contribute to decreased utilization of ankle arthrodesis. However, ankle arthrodesis will still be a valuable tool in the surgeon’s armamentarium to treat ankle arthritis.

Published: September 2018

Category: Ankle Introduction/Purpose: Obesity is a public health concern in the United States, with an overall prevalence of greater than one-third. From a surgical perspective, obesity may increase risk for postoperative complications, including delayed wound healing, infection or compromise of fixation/repair constructs. The purpose of this study was to retrospectively review outcomes data from the American College of Surgeons: National Surgical Quality Improvement Program (NSQIP) to delineate the impact that obesity has on operative treatment of ankle fractures. Methods: Perioperative data was collected from patients undergoing operative intervention for distal fibular or bimalleolar ankle injuries. Patients were identified from the 2006-2015 NSQIP database using current procedural terminology (CPT) codes. Obese (body mass index>30 kg/m2) and non-obese (body mass index<30 kg/m2) cohorts were identified to elucidate the influence of obesity on perioperative /postoperative complications after undergoing operative treatment for distal fibular or bimalleolar ankle injuries. Univariate and multivariate logistic regression models were created to identify independent risk factors for complications. Results: Our study identified a total of 8,377 patients including, 4,357 undergoing surgical bimalleolar ankle fracture repair and 4,020 patients undergoing surgical repair of distal fibular ankle fracture. Obese patients undergoing surgical repair of either distal fibular or bimalleolar ankle fractures were more likely to have a longer length of hospital stay (p < 0.05). Patients undergoing distal fibular fixation were found have a longer operative time. Analysis using logistic regression demonstrated no significant association obesity and DVT/sepsis (bimalleolar ankle fracture fixation) and re-operation/deep incisional SSI/wound complication/UTI (distal fibular ankle fracture fixation) Obesity was not determined to be associated with postoperative complications following distal fibular nor bimalleolar ankle fracture repair. ankle fracture repair. Conclusion: This study demonstrated that, after adjusting for potential confounders, obesity is not significantly associated with adverse outcomes following bimalleolar or distal fibular ankle fracture repair. Further analysis demonstrated that operative time and length of stay are lengthened in ankle fracture fixation in obese patients.
Can Patient Reported Outcomes Guide Therapy Needs in Foot and Ankle Patients?

Category: Other Introduction/Purpose: The patient acceptable symptom state (PASS) is a validated question establishing if patients activity and symptoms are at a satisfactory low level for pain and function. Surprisingly, ~20% of foot and ankle patients at their initial visit present for care with an acceptable symptom state (i.e. PASS yes). These patients are important to identify to prevent over treatment and avoid excessive cost. It is also unclear what health domains (Pain Interference (PI), Physical Function (PF), or Depression (Dep)) influence a patients judgement of their PASS state (i.e. why they are seeking treatment). The purpose of this analysis is to document the prevalance of PASS state and determine the health domains that discriminate PASS patients and predict PASS state at the initiation of rehabilitation. Methods: Patient reported outcomes measurement information system (PROMIS) computer adaptive test (CAT) scales PF, pain PIand Dep and PASS ratings starting in summer 2017 were routinely collected for patient care. Of 746 unique patients in this data set, 114 patients had ICD-10 codes that were specific to the foot and ankle. Average age was 51years (±18) and 54.4% were female. Patients were seen an average of 19.8(±15.9) days from their referral and were billed as low (51.7%), moderate (44.7%) and high complexity (2.7%) evaluations per current procedural code (CPT) visits. ANOVA models were used to evaluate differences in PROMIS scales by PASS state (Yes/No). The area under receiver operator curve (AUC) was used to determine the predictive ability of each PROMIS scale to determine a PASS state. Thresholds for near 95% specificity were also calculated for a PASS Yes state for each PROMIS scale. Results: The prevalance of PASS Yes patients was 13.2% (15/114). Pass Yes patients were significantly better by an average of 7.2 to 8.0 points across all PROMIS health domains compared to PASS No patients (Table 1). ROC analysis suggested that Dep (AUC=0.73(0.07) p=0.005) was the highest predictor of PASS status followed by PI (AUC=0.70(0.08) p=0.012) and PF (AUC=0.69(0.07) p=0.18). The threshold PROMIS t-score values for determining PASS Yes with nearest 95% specificity were PF = 51.9, PI = 50.6, and Dep = 34. Conclusion: Surprising, yet consistent with previous data, 13.2% of patients at their initial physical therapy consultation rated themselves at an acceptable level of activity and symptoms. Health domains of physical function, pain interference, and depression were better in these patients and showed moderate ability (AUC~0.7) to identify these patients. The PROMIS thresholds suggest patients are identified by pain and physical function equal to the average of the US population (PROMIS T-Score ~50) and extremely low depression scores (34). Clinically it is important to recognize these patients and purposefully provide treatments that reinforce their self efficacy and prevent unnecessary costly treatments.

Authors: Indino Cristian , D’Ambrosi Riccardo , Usuelli Federico Giuseppe 
Published: September 2018

Category: Ankle Arthritis Introduction/Purpose: The purpose of this systematic review was to report clinical outcomes on total ankle replacement (TAR) whose data were extracted from national registers. Methods: A systematic review of the literature, to identify all studies reporting outcomes after total ankle replacement, was performed. Two independent investigators performed the research using MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Embase and Cochrane Databases (1950 to December 2017). Results: Analysis of the literature included 18 articles from 2007 to 2017. Of these 5 articles performed a comprehensive analysis of the national registers, 5 articles evaluated complications and reasons of failure after TAR, 6 articles made a specific outcome register analysis, one article compared TAR and ankle arthrodesis while the last one analysed the role of TAR in patients with rheumatoid arthritis. Conclusion: Scientific publications extracted from national joint registers for total ankle replacement provide useful but heterogeneous information on implants survivorship, implant models and risk factors. There is still a discrepancy between the data reported by designers in clinical studies and the data reported by the registries. The centralization of registers in specialized hospitals with dedicated surgeons, the use of patient reported outcomes (PROMs) in association with surgeon assessments and periodical publications can improve the development of registries and consequently of the literature in this regard.

Authors: Kim Hak Jun 
Published: September 2018

Category: Trauma Introduction/Purpose: Identifying predictors of compartment syndrome in the foot after a fracture of the calcaneus may lead to earlier diagnosis and treatment. The aim of our study was to identify any such predictors. Methods: We retrospectively reviewed 303 patients (313 fractures) with a fracture of the calcaneus who presented to us between October 2008 and September 2016. The presence of compartment syndrome and potential predictors were identified by reviewing their medical records. Potential predictors included age, gender, concomitant foot injury, mechanism of injury, fracture classification, time from injury to admission, underlying illness, use of anticoagulant/antiplatelet agents, smoking status and occupation. Associations with predictors were analyzed using logistic regression analysis Results: Of the 313 fractures of the calcaneus, 12 (3.8%) developed a compartment syndrome. A Sanders type IV fracture was the only strongly associated factor (odds ratio 21.67, p = 0.007). Other variables did not reach statistical significance. Conclusion: A Sanders type IV fracture is the best predictor of compartment syndrome after a fracture of the calcaneus.

Authors: Miao Xu-dong , Cao Le 
Published: September 2018

Category: Trauma Introduction/Purpose: Transfer of a flexor hallucis longus (FHL) tendon can not only reconstruct the Achilles tendon but also provide ischemic tendinous tissues with a rich blood supply to enhance wound healing. This retrospective study aims to investigate clinical outcomes in patients who underwent repair of Kuwada grade IV chronic Achilles tendon rupture with long hallucis longus tendons harvested using a minimally invasive technique. Methods: 35 patients who were treated for Kuwada grade IV Achilles tendon injuries from July 2006 to June 2011 were included in this retrospective study. The age ranged between 23 and 71 years. The duration from primary injury to surgery ranged from 29 days to 34 months (mean value, 137.6 days). All 35 patients had difficulties in lifting their calves. 32 were followed up for a mean 32.2 months (range 18-72 months), whereas 3 were lost to follow-up. Magnetic resonance imaging (MRI) showed that the tendon rupture gap ranged from 6.0 to 9.2 cm. Postoperative appearance and function were evaluated by physiotherapists based American Orthopedic Foot and Ankle Society-ankle and hindfoot score (AOFAS-AH), and Leppilahti Achilles tendon ratings. Results: Results were assessed in 32 patients. Except for one patient who suffered complications because of wound disruption 10 days after the operation, all other patients had primary wound healing, with 28 of 32 able to go up on their toes at last follow-up. The AOFAS-AH score was increased from preoperative (51.92 ± 7.08) points to (92.56 ± 6.71) points; Leppilahti Achilles tendon score was increased from preoperative (72.56 ± 7.43) to (92.58 ± 5.1). There were statistically significant differences. The result of the total excellent and good rate was 93.8% (30/32). MRI of Achilles tendon showed even signal without evidence of tear or cystic degeneration. Conclusion: Reconstruction of a chronic Achilles tendon rupture with an FHL tendon harvested using a minimally invasive technique showed good outcomes.

Published: September 2018

Category: Trauma Introduction/Purpose: To assess participation in sport and physical activity following open reduction and internal fixation of a Lisfranc injury in a cohort of recreational athletes. Methods: Our study identified all adult patients aged 55 or less, who presented to our institution with a Lisfranc injury and underwent open reduction and internal fixation (ORIF) using a Lisfranc screw combined with bridge plating technique. Sports and physical activity participation was assessed with a new sports-specific, patient-administered questionnaire. Clinical outcomes were assessed with the Foot and Ankle Outcome Score (FAOS). Results: Thirty-three patients qualified for the study (21 males/12 females). Mean age and follow-up: 31.2 (range, 18-55) years and 2.9 (range, 1.5-5.4) years, respectively. Post operatively, 31 patients (94%) were able to return to some form of sport. Twenty-two patients (66%) returned to playing sport at or above their pre injury level. Of the 11 patients who played less sport, 6 had ongoing pain, and the remaining 5 were asymptomatic but were participating less frequently due to other lifestyle reasons. In addition, of the 33 patients, 11 (33%) had some degree of ongoing pain that might limit their ability to return to sports and physical activities. There was strong correlation between overall FAOS and the Sports Questionnaire. Conclusion: The majority of patients sustaining a Lisfranc injury can return to sport and physical activity after ORIF. Patients should be counseled preoperatively that about one in three might experience continued pain at the injury site
Does Use of Demineralized Bone Matrix Affect the Union Rate in Arthroscopic Ankle Fusions?
Authors: Neumann Julie , Weinberg Maxwell , Zhang Chong , Saltzman Charles , Barg Alexej 
Published: September 2018

Category: Ankle Introduction/Purpose: Despite DBM having positive effects on union rates in other subspecialties of orthopaedics, there is a general lack of evidence about bone graft substitutes in foot and ankle surgery. To our knowledge, orthopaedic surgeons have never evaluated the use of demineralized bone matrix (DBM) as it pertains to the union rate of arthroscopic ankle fusions. The purpose of this clinical study is to compare the rate of union in arthroscopic ankle fusions in patients that have had DBM to those without DBM. The hypothesis of this study was that use of DBM would increase the union rate in all patients undergoing arthroscopic ankle arthrodesis. Methods: This is a retrospective review of 521 consecutive patients from October 2002 to April 2016. Seventy-one ankles from 68 patients met inclusion criteria. These patients underwent primary arthroscopic ankle arthrodesis. Forty patients had DBM and 31 patients did not have DBM. Age, gender, body mass index, smoking, and preoperative radiographic deformity were controlled. The primary outcome measure was union rate of arthroscopic ankle arthrodesis. Secondary outcome measures were time to union, rate of wound complications, rate of return to operating room, and rate of development of post-operative deep vein thrombosis (DVT). Results: Seventy-one patients were available for final follow-up. Average age of the patients was 55.3 +/- 17.6 years. The mean follow-up time was 39.5 months. Unions were assessed on routine post-operative radiographs. If there was a concern for nonunion, patients were further assessed with a computerized tomography scan. Nonunion rate of patients who did have DBM was 7/40 (18%) and nonunion rate of those who did not have DMB was 8/31 (26%) (p=0.40). There was no statistically significant difference between those who did have DBM and those who did not have DBM in wound complication rate (5% vs 6%, p=1.0), rate of return to the operating room (35% vs 39%; p=0.75), and DVT rate (0% vs 0%), respectively. There were no major complications in this study. Conclusion: This study is the largest study to directly compare union rate and complications in patients who had DBM versus those who did not in the setting of arthroscopic ankle fusion. In this study, use of DBM does not affect union rate in patients undergoing arthroscopic ankle arthrodesis. Additionally, use of DBM does not affect the rate of wound complications, return to the operating room, and development of post-operative DVT.
