Despite known risks of hyperglycemia on postoperative complications, the influence of intraoperative dexamethasone on blood glucose has yet to be evaluated within the diabetic limb salvage population. This study aimed to assess the effect of intraoperative dexamethasone on postoperative blood glucose in diabetic patients undergoing atraumatic major lower extremity amputations. A single-center retrospective review of diabetic patients undergoing below-knee amputation between January 2017 through December 2022 was performed...

The purpose of this study is to determine the financial practicality for the use of nasal povidone-iodine (NP-I) in the preoperative holding area in attempt to decrease the rate of infection that is associated with operative fixation of closed pilon fractures. Institutional costs for treating postoperative infection following a closed pilon fracture, along with costs associated with preoperative NP-I use, were obtained. A break-even equation was used to analyze these costs to determine if the use of NP-I would decrease the current infection rate (17%) enough to be financially beneficial for routine use preoperatively...

Charcot Neuroarthropathy's (CN) anatomic classification was originally formulated by the Brodsky article and the Trepman et al modification, including midfoot (type 1), rearfoot (type 2), ankle (type 3a), calcaneus (type 3b), multi-articular (type 4), and forefoot (type 5). In these classic studies, ankle joint and multi-joint CN are reported as 9% and 6-9%, respectively, but we believe ankle CN to be more common than that in a tertiary setting. We retrospectively reviewed patients presenting initially or as referral between 2004-2020...

The main object of this prospective cohort study was to compare surgical treatment options for primary metatarsalgia and the severe instability of lesser metatarsophalangeal joints. The outcomes of triple Weil osteotomy combined with direct plantar plate repair and triple Weil osteotomy, performed with proximal interphalangeal joint arthrodesis, are analyzed and compared. One hundred and thirteen patients (117 feet) were enrolled in the study. They were split into two groups. In the first group, undergoing Weil osteotomy, combined with the plantar plate repair, good results, including complete pain reduction, elimination of hyperkeratosis, AOFAS improvement, were achieved in 84...

The focal dome osteotomy allows deformity correction through frontal plane rotation, and if needed, anterior or posterior translation. This percutaneous technique allows extracapsular ankle realignment with minimal soft tissue dissection. While circumventing a standard anterior incision, this technique encounters soft tissue structures that must be considered. Focal dome osteotomies were simulated on ten fresh-frozen below the knee cadavers. Centered proximal to the tibial plafond at the physeal scar, a radial arm using a four-hole Rancho cube was used to map the dome...

The purpose of this study was to explore the difference between congruency and incongruency of the first metatarsophalangeal (MTP) joint in hallux valgus using weight-bearing CT (WBCT) and to identify the risk factors for incongruency. From January 2019 to January 2021, WBCT scans were retrospectively analyzed for 110 (191 feet) consecutive patients. According to whether the metatarsal articular surface and phalanx articular surface were parallel, they were divided into congruency (73 feet) and incongruency groups (118 feet)...

The objective of this cadaveric biomechanical study was to evaluate if the center-center surgical technique is a reliable and repeatable method of achieving proper syndesmotic reduction when using dynamic syndesmotic fixation. Nine fresh frozen above-knee cadaveric lower extremities were used. Computerized tomography (CT) scans were first obtained for each intact specimen as the baseline for comparison. A simulated complete syndesmotic disruption was created by transection of all deltoid and syndesmotic ligaments...

The arthroscopic Brostrom procedure is a minimally invasive technique that is a viable option surgeons have to treat patients with chronic lateral ankle instability (CAI). Our hypothesis was that there will be a statistically significant difference in pre- and postoperative scores and that patient satisfaction scores remained consistent at a minimum of 5 years post-operatively. Pre-operative American Orthopedic Foot and Ankle (AOFAS) hindfoot scores, visual analog scale (VAS), foot function index (FFI) were compared with post-operative scores...

The use of bioabsorbable magnesium (Mg) screws is new in foot surgery. Their relative merit over conventional titanium screws has not yet been proven. This prospective case series study was conducted to compare the clinical and radiological outcomes of bioabsorbable Mg screws and titanium screws. A consecutive series of patients (n=60; 11 men and 49 women) underwent corrective hallux valgus surgery. The minimum follow-up period was 1 year. The assessment was based on a patient questionnaire, including the American Orthopedic Foot and Ankle Society (AOFAS) hallux valgus score, visual analog scale, patient's global impression of change (PGIC), and fifth metatarsus circumference (IF5C)...

Radiographic measurements are frequently used to classify deformity and determine treatment options. Correlation coefficients can be used to determine inter- and intra-rater reliability. Reliability is a required feature of any measurement if the measurement is to provide valid information. We calculated correlation coefficients for standard radiographic measurements used to categorize foot deformities: this was done for 52 sets of radiographs assessed by 5 raters. We aimed for generalizability, and kept rater instructions to match what was originally published for each measurement of interest with schematic illustration...

Percutaneous antegrade (anterior to posterior (AP), or proximal to distal) fixation for subtalar joint (STJ) arthrodesis offers various intraoperative and biomechanical advantages. Currently, the entry point for percutaneous antegrade STJ screw fixation is not clearly described and variable. To our knowledge, there are no publications that evaluate anatomic structures at risk or define an anatomically safe entry point for this fixation. The aim of this investigation was to define an anatomically safe and reproducible entry point for percutaneous antegrade STJ arthrodesis fixation, while also describing anatomic structures at risk when undertaking this method of fixation...

Whether secondary to deformity, traumatic injury, infection, neoplasm, or ischemic disease, the transmetatarsal amputation provides a functional means of limb preservation prior to major proximal amputation. With similar readmission rates following inpatient and outpatient surgery, prevention of an unnecessary admission among vulnerable patients, specifically geriatrics, proves beneficial. This investigation examines differences among geriatric patients admitted and not requiring readmission following outpatient transmetatarsal amputation...

Current recommendations on thromboprophylaxis for foot and ankle (FA) surgery are often inconsistent and generally based on weak evidence. The aim of this survey study was to evaluate the current practice among orthopedic surgeons regarding venous thromboembolism (VTE) prophylaxis following FA surgery. From February 2019 to March 2020, an online questionnaire was sent by e-mail to orthopedic societies across the world. The questionnaire was hosted by the International Society of Thrombosis and Haemostais (ISTH) RedCAP platform...

Open reduction with internal fixation of Lisfranc injuries are associated with an increased risk for secondary surgery including hardware removal and salvage arthrodesis. In the current literature, rates of salvage arthrodesis vary due to small sample sizes and a low incidence of Lisfranc injuries. There is little evidence to identify specific surgical and patient-related variables that may result in later arthrodesis. The purpose of this study is to determine the rate of tarsometatarsal joint arthrodesis following Lisfranc ORIF in a relatively large sample size...

Minimally invasive (MIS) surgery has gained popularity for hallux valgus correction in the adult population. The advantage of reproducibility of this procedure can aid in lower operating room costs, quicker recovery, and fewer complications. The purpose of this retrospective study was to compare pre-operative versus post-operative foot widths in patients that underwent MIS hallux valgus correction. The average pre-operative foot width was 101.1 ± 5.67 mm and post-operatively the foot width measured at 12-month follow-up was 95...

The goal of our study is to compare the stability of the anatomic reconstruction of the anterior talofibular ligament (ATFL) with direct repair of the ATFL, in a cadaver model. We performed the following techniques in 18 cadaveric ankles: the intact ATFL was cut, after which a direct repair using two anchors was performed. The repair was sectioned, and anatomic reconstruction was then performed with a tendon autograft. We measured angular displacement in three anatomic planes (axial, coronal, sagittal) for each situation in response to the anterior drawer test (ADT), talar tilt test (TTT) and pivot test (PT), using a specifically constructed arthrometer...

The use of staples has been shown to be a reasonable fixation technique to achieve stability of a 1st MTPJ arthrodesis. Although it has been shown to be a weaker construct than crossed screws or plate and screw combinations, their ease of insertion, low profile, and stability make them a desirable choice for 1st MTPJ arthrodesis fixation. However, because of this relative weakness, the question remains whether immediate weight bearing when using staples is advisable. The aim of this study is to determine whether the use of 2 nickel-titanium alloy (NITINOL) staples, placed at 90 degrees to one another is a stable enough construct to support full, immediate weight bearing following 1st MTPJ arthrodesis...

Split-thickness skin grafts can provide effective autologous wound closure in patients with dysvascular comorbidities. Meshing the graft allows for reduced donor site morbidity and expanded coverage. This study directly compares outcomes across varying meshing ratios used to treat chronic lower extremity wounds. Patients who received split-thickness skin grafts to their lower extremity for chronic ulcers from December 2014 to December 2019 at a single center were retrospectively reviewed. Patients were stratified by meshing ratios: non-meshed (including pie crusting), 1...

The Foot and Ankle Disability Index (FADI) is one of the most commonly used tools for evaluating foot and ankle function. Due to the lack of a Korean version for properly evaluating Koreans, it was not possible to compare Korean data with data from other countries using FADI. Therefore, we created a Korean version of the FADI questionnaire and evaluated its reliability and validity. We translated the English version of FADI and FADI-sport into Korean and then back into English. The Korean version of the FADI and FADI-sport, the previously verified visual analog scale (VAS) score, and the previously validated Medical Outcomes Study Short-Form 36-item questionnaire (SF-36) were administered to outpatients with chronic foot and ankle pain...

The purpose of this paper is to assess the prevalence and injury patterns of the calcaneofibular ligament (CFL) in chronic lateral ankle instability (CAI) patients using ultrasound imaging. This retrospective study included 938 ankle ultrasound images from January 2016 to May 2018. The patients' demographic data and the injury pattern classified by the injury location and the remnant quality were recorded and correlated using t tests, Fisher's exact tests, and post hoc tests accordingly. Of the 938 CAI patients, CFL injury was found in 408/938 (44%)...
