The purposes of this study was to determine the prevalence of the accessory anterolateral talar facet (AALTF); to evaluate the relationship between AALTF, focal abutting bone marrow edema (FABME), and sinus tarsi edema; and to study the prevalence of tarsal coalitions in patients with the AALTF utilizing ankle MR images. 5-T ankle MR images were re...

Hindfoot valgus malalignment has been assessed on coronal MRI by the measurement of the tibio-calcaneal (TC) angle and apparent moment arm (AMA). This study aimed to determine if the calcaneofibular ligament (CFL) angle could be used as a further marker of hindfoot valgus malalignment on routine non-weight-bearing ankle MRI. One hundred ninety-five...

BackgroundWeightbearing of the hindfoot affects positional changes of the ankle joint and subtalar joint (ankle-joint complex [AJC]). However, it is difficult to assess the kinematic changes in the hindfoot in a natural full weightbearing condition using conventional CT or cone beam computed tomography (CT) due to limitations of acquiring foot imag...

Ankle impingement refers to a chronic painful mechanical limitation of ankle motion caused by soft-tissue or osseous abnormality affecting the tibiotalar joint or extraarticular soft tissues. Impingement can be associated with a prior single traumatic event or repetitive microtrauma, often in an adolescent with anatomical predisposition. Impingemen...

Category: Hindfoot, Trauma Introduction/Purpose: Surgical treatment of avulsion fractures of the calcaneus has a reported fixation failure rate as high as 23%, and there is much controversy surrounding the best method of treatment for these fractures. We present a technique for fixation of calcaneal avulsion fractures utilizing a bone anchor suture...

Category: Hindfoot Introduction/Purpose: Patient Reported Outcomes Instrumentation System (PROMIS) pain interference (PI) and physical function (PF) scales were recently validated for foot & ankle surgery. Few studies have explored PROMIS in advanced posterior tibial tendon dysfunction (PTTD) surgery. We examined the change in PROMIS scores after P...

Category: Ankle, Ankle Arthritis, Hindfoot, Midfoot/Forefoot Introduction/Purpose: Degenerative conditions of the ankle, hindfoot, and midfoot can markedly limit mobility. The Life-Space Assessment (LSA) is a questionnaire quantifying how patients mobilize after a medical event as they return to their previous daily settings. Current outcome measur...

Category: Hindfoot, Trauma, Ankle Introduction/Purpose: Complete talar extrusion is a rare injury resulting from high-energy trauma, with dissociation of the talus from surrounding bony and soft-tissue structures. Complications after complete talar extrusion include infection, osteonecrosis, posttraumatic osteoarthritis, and leg-length discrepancy....

Category: Hindfoot Introduction/Purpose: Subtalar arthrodesis is an invaluable tool in managing arthritis, deformity, and muscular imbalance of the hindfoot. However, failed arthrodesis is complicated by bone necrosis, sclerosis with loss of bone, less than ideal biologic settings, and the literature reports a high rate of non-union. The aim of thi...

Category: Ankle, Arthroscopy, Hindfoot, Sports Introduction/Purpose: Posterior ankle/hindfoot arthroscopy (PAHA) is an established surgical option for treating pathologies, of posterior ankle and subtalar joints, which otherwise would require open incisions. Arthroscopic procedures are less invasive, provide magnified visualization and allow earlie...
