Comparative Study
Biomechanical Comparison of Intramedullary Screw Versus Low-Profile Plate Fixation of a Jones Fracture.
Intramedullary screw fixation of fifth metatarsal Jones fractures often produces satisfactory results, however, nonunion and refracture rates are not negligible. The low-profile "hook" plate is an alternative fixation method that has been promoted to offer improved rotational control at the fracture site, but this remains to be proven. The purpose of this study was to document biomechanical performance differences between this type of plate and a contemporary solid, dual-pitch intramedullary screw in a cadaveric Jones fracture model. ⋯ Although low-profile "hook" plates offer an alternative for fixation of fifth metatarsal Jones fractures, intramedullary screw fixation may provide better resistance to bending and initiation of fracture site rotation. The influence of these mechanical characteristics on fracture healing is unknown, and further clinical investigation is warranted.

Comparative Study
Predictors of Postoperative Wound Necrosis Following Primary Wound Closure of Open Ankle Fractures.
Most open malleolar ankle fracture wounds can be closed primarily after meticulous debridement. However, the development of wound necrosis following operative treatment of open malleolar ankle fractures can have catastrophic consequences. The aim of this study was to identify risk factors predisposing to postoperative wound necrosis following primary wound closure of open malleolar ankle fractures. ⋯ Level III, retrospective comparative series.

Comparative Study
Correlation of Postoperative Position of the Sesamoids After Chevron Osteotomy With Outcome.
Postoperative incomplete reduction of the sesamoids has been identified as a potential risk factor for hallux valgus recurrence after proximal osteotomy. However, it is not known whether the postoperative sesamoid position is a risk factor in hallux valgus correction via distal chevron osteotomy with or without dorsal webspace release (DWSR). ⋯ Level III, retrospective comparative study.

Bunionette deformity is characterized as head hypertrophy, lateral bowing, or splaying of the fifth metatarsal, or a combination of these deformities. Most previous studies have focused on the fourth and fifth metatarsals; few have analyzed the radiographic morphologic characteristics of the entire foot. The morphologic characteristics of the entire foot in cases of symptomatic bunionette deformity were analyzed with a radiographic image-mapping system. ⋯ Level III, retrospective comparative study.

Comparative Study
Effect of Obesity on Clinical and Radiographic Outcomes Following Reconstruction of Stage II Adult Acquired Flatfoot Deformity.
Obesity is a known risk factor for the development of adult acquired flatfoot deformity (AAFD), but obesity's effects on outcomes following AAFD reconstruction are unknown. We hypothesized that obesity would negatively impact outcomes following joint-preserving stage II AAFD reconstruction. ⋯ Level III, retrospective cohort study.
