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.

A prior study demonstrated statistical widening of the syndesmosis within weeks of elective screw removal. However, no information is available as to the radiographic outcomes of screw retention. The aim of this study was to evaluate radiographic syndesmotic widening and talar shift over time in patients treated with syndesmotic screws and to compare screw removal with retention along with other potential risk factors that may have led to tibia-fibula diastasis after weightbearing. ⋯ 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.

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.

A popliteal nerve block is a common analgesic procedure for patients undergoing surgery on their knee, foot, or ankle. This procedure carries less risk in a surgical setting compared with other forms of anesthesia such as a spinal block. Previous reports demonstrated few to no complications with the use of this nerve block, but it is unclear whether these data are consistent with the recent increase in use of this analgesic procedure for lower extremity surgery. ⋯ Level IV, retrospective case series.
