Current literature reports excellent rates of union following various lesser metatarsal osteotomy techniques. However, it is our experience that segmental midshaft shortening osteotomies heal very slowly and have a greater potential for nonunion than has previously been reported. The purpose of this study was to assess union rates and report the time required for segmental midshaft shortening osteotomies to achieve radiographic union. ⋯ Level IV, retrospective case series.

Preoperative computer navigation and patient-specific instrumentation have had promising results in total knee arthroplasty and in a previous cadaveric total ankle arthroplasty (TAA) study. Potential benefits of patient-specific guides include improved implant alignment and decreased surgical time. The purpose of this retrospective case series was to evaluate the accuracy, reproducibility, and limitations of TAA tibia and talar implant placement and radiographic alignment using preoperative computed tomography (CT) scan-derived instrumentation in a clinical setting. ⋯ Level IV, retrospective case series.

Impact of Diabetes on Outcome of Total Ankle Replacement.
As the incidence of diabetes mellitus (DM) grows, managing patients with diabetes and concomitant ankle arthritis poses a challenging clinical dilemma. While diabetes is known to be a risk factor for complications relating to open reduction and internal fixation of ankle fractures, it is unclear if DM is a risk factor for negative outcomes after total ankle replacement (TAR). ⋯ Level III, retrospective comparative study.

Chronic ruptures of the tibialis anterior tendon are often associated with tendon retraction and poor-quality tissue, resulting in large segmental defects that make end-to-end repair impossible. Interpositional allograft reconstruction has previously been described as an operative option in these cases; however, there are no reports of the clinical outcomes of this technique in the literature. ⋯ Level IV, retrospective case series.
