INTRODUCTION: Patient-specific instrumentation (PSI) has been developed for total ankle arthroplasty (TAA), with proven benefits. One concern regarding PSI is the need for more soft tissue dissection in order to accurately position the PSI guides, which has the theoretical disadvantage of increased osteolysis. The purpose of our study is to compare the incidence and magnitude of osteolysis for the INFINITY Total Ankle System between PSI and standard referencing (SR) techniques. METHODS: Sixty-seven patients who underwent primary TAA using Prophecy (PSI) or SR technique between 2013 and 2015 were reviewed in a retrospective observational study...

We sought to determine whether significantly displaced Lisfranc injuries had a higher rate of loss of reduction after fixation compared to those with low displacement. Forty-five patients who had fixation of an acute Lisfranc injury from 2005 to 2014 were retrospectively reviewed. All patients underwent subsequent hardware removal at 3 to 15 months after their index procedure. Radiographs were reviewed from the time of injury, 2 weeks, and 6 months postoperative. Lisfranc joint reduction was assessed using criteria previously described in the literature and graded as malreduced if displacement was >2 mm...

The anterior lateral malleolar artery (ALMA), which usually originates from the anterior tibial artery (ATA), courses transversely and laterally, passing under the extensor digitorum longus and peroneus tertius tendons. Variations in the origin of the ALMA from the ATA can occur. Branches of the ATA, such as the ALMA, are prone to pseudoaneurysm. This study reviewed the origin of the ALMA from the ATA and aimed to identify problems in anterior ankle arthroscopy that might cause injury to the ALMA. Enhanced computed tomography scans of 24 feet of 24 fresh cadavers (13 males, 11 females; average age 78...

BACKGROUND: While biomechanical characteristics of locking screw fixation versus traditional plating has been studied extensively in orthopaedic literature, clinical outcome studies are lacking. The goal of this study was to evaluate the efficacy and complications rate of locking versus traditional nonlocking screws in complex ankle fractures employing distal fibula internal fixation with 1/3 semitubular small fragment plates. METHODS: A retrospective review was performed between January 2010 and June 2013 of all patients in whom internal fixation of the fibula in an ankle fracture (open or closed) was performed using only 1/3 semitubular small fragment fibular plates...

Diabetic foot ulcers (DFUs) are usually treated with conservative management based on debridement, topical agents, and nonsurgical off-loading; however, the recurrence rate following such standard care is reported to be high. In the case of recalcitrant or recurrent ulcers, a surgical off-loading technique such as the metatarsal osteotomy (MO) is indicated. Thus, the aim of this study is to conduct a meta-analysis evaluating the efficacy of MO in treating DFUs. Four relevant studies were identified, including 119 patients with 129 DFUs; all wounds were refractory to a previous conservative treatment of a mean duration of 10...

INTRODUCTION: Peroneal tendon disorders pose a diagnostic conundrum to the clinician. Magnetic resonance imaging (MRI) is widely used to assess tendon pathology. A recognized artifact of MRI, the magic angle effect (MAE), can lead to spurious results and inappropriate management. The aim of this study is to assess whether T2 fat-suppressed sequences (T2FSs) reduce the frequency of MAE compared with proton density fat-suppressed (PDFS) images. METHODS: MRI scans of 18 patients were prospectively assessed for MAE...

BACKGROUND: We hypothesized that the cause of second-ray pathology with hallux valgus is excessive relative length of the second metatarsal and performed Weil osteotomy to shorten it, with correction of hallux valgus. The purpose of this study is to evaluate the outcome of second-ray pathology after distal chevron osteotomy (DCO) with Weil osteotomy to correct metatarsal parabola. METHODS: We performed concomitant Weil osteotomy of the second metatarsal with DCO of the first metatarsal as part of hallux valgus with second-ray pathology correction surgery in 45 feet (40 patients)...

Chronic kidney disease (CKD) is a major concern in patients with foot disease because it is associated with high rates of neuropathy, peripheral vascular disease, and poor wound healing. The purpose of this study was to evaluate renal dysfunction as a risk factor for reamputation after initial transmetatarsal amputation (TMA). Patients who underwent a TMA were retrospectively identified in the American College of Surgeons National Surgical Quality Improvement Program database. Of 2018 patients, reamputation after TMA occurred in 4...

INTRODUCTION: Soft tissue defects in the distal leg and foot are challenging conditions for reconstruction. The widely used reverse sural fascio-cutaneous flap (RSFCF) has been reported with large variation in complication frequency. Some authors reported higher complications in the diabetic population when compared with trauma patients. We compared the reliability of the RSFCF in treating such defects among both populations. METHODS: This is a retrospective series with a prospective data collection of 24 patients (11 with type 2 diabetes and 13 in trauma settings) treated with an ipsilateral RSFCF for soft tissue defects of the distal leg and the rear foot...

INTRODUCTION: Obesity is an increasingly common comorbidity that may negatively affect outcomes following orthopaedic surgery. It is valuable to determine whether obese patients are vulnerable for postoperative complications. The purpose of this study was to analyze data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) to determine the effect of obesity on surgical treatment of Achilles tendon ruptures. METHODS: Patients who underwent a surgical repair of the Achilles tendon were retrospectively identified through the ACS NSQIP...

BACKGROUND: Lateralizing calcaneal osteotomy (LCO) is a common procedure used to correct hindfoot varus. Several complications have been described in the literature, but only a few articles describe tibial nerve palsy after this procedure. Our hypothesis was that tibial nerve palsy is a common complication after LCO. METHODS: A retrospective study of patients undergoing LCO for hindfoot varus between 2007 and 2013 was performed. A total of 15 patients (18 feet) were included in the study...

Allogenic bone graft has long been accepted as a standard of care in the surgical arthrodesis of the foot and ankle and treatment of certain high-risk, comminuted fracture types that have greater potential for delayed union or nonunion. It has been shown in multiple studies to be equivalent to autograft in regard to union rates without the morbidity associated with bone graft harvest. We present a retrospective study on the efficacy of an allogenic cancellous/periosteal cellular bone matrix with mesenchymal stem cells and angiogenic growth factors...
