Use of Computed Tomography (CT) to evaluate syndesmotic reduction following injury has significantly increased in recent years. The aim of this study was to compare existing clinical measurements of syndesmotic reduction to gold standard measurements of fibular motion obtained from a full 3D model. ⋯ While the clinical measurements were adequately reproducible, they showed only moderate to small correlations with the 3D measurements of movement of the fibula in the longitudinal, medial/lateral or rotational directions. The only fibular translation measured by the 3D model that was well described by the three clinical measures was fibular movement in the anterior/ posterior direction. This work demonstrates a need for improved clinical measurements of syndesmotic congruity on axial CT scans to serve as surrogates for the true movement of the fibula.

Periprosthetic distal femur fractures are severe injuries occurring in the often osteoporotic bone of the elderly. Far cortical locking (FCL) screws, which have been shown to promote increased callus formation in animal models, have recently become available for clinical use. The purpose of this study is to report preliminary healing and complication rates of periprosthetic distal femur fractures treated with FCL constructs. ⋯ The initial results of this study are comparable to results reported for distal femur periprosthetic fractures treated with locking plate fixation without FCL screws, although it was difficult to compare time to healing between previously published studies. It is the impression of the authors that callus appears earlier and is more robust and uniform between the three cortices in FCL cases compared to their previous experiences with traditional locking plate periprosthetic distal femur fractures. This work suggests that FCL screws may be superior to traditional locking constructs but further studies are needed to directly compare the two methods.

The medial patellofemoral ligament (MPFL) is the most frequently injured soft tissue structure following acute lateral patellar dislocation. MPFL reconstruction has become a popular option to restore patellar stability following lateral patellar dislocation due to the high incidence of recurrent instability following conservative management. Anatomic reconstruction of the MPFL minimizes graft length changes during full knee range of motion and restores patellar stability. ⋯ Anatomic MPFL reconstruction displays similar lateral restraining force compared to the intact MPFL at low levels of lateral displacement. At higher levels of displacement, the reconstructed MPFL provides increased lateral restraining force compared to the intact MPFL, improving patellar stability in pathologic knees.

Randomized, controlled study in a laboratory setting. Blinded observations/assessment of study outcomes. ⋯ In this commonly used rabbit posterolateral fusion model, SiCaP EP utilized as a stand-alone, as a stand-alone with BMA, and as an autograft (ICBG) extender produces results that are clinically and radiographically similar to ICBG.

Outcomes following operative treatment of open fractures of the distal radius: a case control study.
To report radiographic, clinical, and patient-based functional outcomes following contemporary operative treatment of patients who sustained an open distal radius fracture and compare them to a similar group of patients treated operatively for closed distal radius fractures. ⋯ Open distal radius fractures treated with early debridement and fixation achieved similar outcomes to surgically treated closed fractures of the distal radius when followed for a year or more postoperatively.
