Multicenter Study
Tibiotalocalcaneal fusion using the hindfoot arthrodesis nail: a multicenter study.
Tibiotalocalcaneal arthrodesis is a salvage option for severe ankle and hindfoot deformities, arthritis of the ankle and subtalar joints, avascular necrosis of the talus, failed total ankle arthroplasty, and Charcot arthropathy. This multicenter study reports clinical experience with the hindfoot arthrodesis nail (HAN) in the treatment of patients with severe ankle and foot abnormalities. ⋯ Level IV, retrospective case series.

Flexor hallucis longus (FHL) and flexor digitorum longus (FDL) tendon transfers are frequently used to restore the function of a deficient tibialis posterior tendon in stage II adult acquired flatfoot deformity (AAFD). Either transfer causes some loss in toe flexion force, although the decision to tenodese the cut tendon to restore associated function remains controversial. This study quantified changes in plantar force before and after tendon transfer and with or without distal tenodesis in a cadaveric model. ⋯ This cadaveric study shows that the FHL is more biomechanically suitable for tibialis posterior tendon insufficiency than the FDL, which may be a basis for a study to investigate whether it is superior in a clinical situation.

Successful screw fixation of reduced posterior facet fragments to the unexposed, nondisplaced sustentaculum tali avoids breaching the subtalar joint or disrupting surrounding soft tissue structures. Safe passage for screw fixation through this narrow bony corridor has not been rigorously defined. ⋯ The operative guidelines described in this study may assist surgeons in the placement of screws for the fixation of posterior facet fragments to the sustentaculum tali.

Comparative Study
Correction and recurrence of ankle valgus in skeletally immature patients with multiple hereditary exostoses.
Ankle valgus is encountered in children with a variety of congenital musculoskeletal disorders, including multiple hereditary exostoses (MHE). Guided growth with temporary distal tibial medial hemiepiphysiodesis (DTMH) may correct the deformity; however, exostoses about the ankle commonly observed in MHE patients may hinder correction and increase the risk of recurrence. Thus, the purpose of this study was to review the outcomes of DTMH in treatment of ankle valgus in MHE versus other diagnosis (non-MHE). ⋯ Level III, retrospective comparative study.

A fairly high prevalence of wound complications after open reduction and internal plate fixation (ORIF) of closed calcaneal fractures via the extensile lateral approach has been reported. The goal of this study was to analyze and identify independent risk factors for wound complications among closed calcaneal fractures undergoing ORIF. ⋯ Level III, retrospective comparative series.
