Various techniques of reconstruction of deformed Charcot hindfoot using different internal fixation devices have been described in the literature. We present our surgical technique using specific principles that has resulted in improved outcomes to allow correction of deformity, obtain stability and allow progression to weightbearing in orthotic sh...

Magnetic resonance imaging (MRI) plays a critical role in disease characterization of intra-articular tenosynovial giant cell tumor. To characterize the MRI features of intra-articular tenosynovial giant cell tumor in children with respect to disease subtype and anatomical location. This retrospective study included children with tenosynovial giant...

The aims of this study were to compare male versus female and dominant versus non-dominant kinematics in the ankle and hindfoot, and to characterize coupled motion between the subtalar and tibiotalar joints during the support phase of gait. Twenty healthy adults walked on a laboratory walkway while synchronized biplane radiographs of the ankle and ...

Midfoot and ankle movement dysfunction in people with diabetes mellitus and peripheral neuropathy (DMPN) is associated with midfoot deformity and increased plantar pressures during gait. If midfoot and ankle motion during heel rise and push-off of gait have similar mechanics, heel rise performance could be a clinically feasible way to identify abno...

Pes cavovarus is a foot deformity that can be idiopathic (I-PC) or acquired secondary to other pathology. Charcot-Marie-Tooth disease (CMT) is the most common adult cause for acquired pes cavovarus deformity (CMT-PC). The foot morphology of these distinct patient groups has not been previously investigated. The aim of this study was to assess if mo...
Introduction: In three-dimensional gait analysis, anatomical axes are defined by and therefore sensitive to marker placement. Previous analysis of the Oxford Foot Model (OFM) has suggested that the axes of the hindfoot are most sensitive to marker placement on the posterior aspect of the heel. Since other multi-segment foot models also use a simila...

Bone defects to the distal tibia, foot, and ankle can be challenging to reconstruct. The induced membrane (Masquelet) technique has become an established method of repair for challenging areas of bone loss. It has been applied in acute open fractures, chronic nonunion, osteomyelitis, and gout erosion. This article presents a systematic review of di...

Category: Hindfoot Introduction/Purpose: The primary aim of this study was to calculate the mean values of three most frequently measured parameters for hindfoot alignment determination in asymptomatic subjects - hindfoot alignment angle (HAA), hindfoot alignment ratio (HAR), and hindfoot moment arm (HMA). The secondary aim was to determine the rel...

Category: Hindfoot; Trauma Introduction/Purpose: Fractures of the talar head are very rare accounting for just 5-10% of talus fractures and fewer than 1% of all fractures. As such, limited clinical literature is available to guide management of these injuries. We present the largest clinical series on talar head fractures to date. Methods: We perfo...

Category: Hindfoot Introduction/Purpose: Tibiocalcaneal (TC) arthrodesis is commonly performed in patients with severe hindfoot disease. These include severe Charcot deformities, ankle malformations, chronic osteomyelitis (COM), and avascular necrosis (AVN). The talar vasculature becomes disrupted to the point that the bone can no longer be salvage...
