PROMIS Physical Function Computer Adaptive Test Compared With Other Upper Extremity Outcome Measures in the Evaluation of Proximal Humerus Fractures in Patients Older Than 60 Years.

Objectives: To compare the PROMIS Physical Function Computer Adaptive Test (PROMIS PF CAT) to commonly used traditional PF measures for the evaluation of patients with proximal humerus fractures.

Design: Prospective.

Setting: Two Level I trauma centers.

Comparison of locked plate fixation and nonoperative management for displaced proximal humerus fractures in elderly patients.

Use of locked plate fixation for proximal humerus fractures in elderly patients has increased markedly in recent years. We conducted a study to compare outcomes of operative (locked plate fixation) and nonoperative management of these fractures. From our database, we identified 207 displaced proximal humerus fractures that met all inclusion and exclusion criteria.

Delayed Primary Closure of Fasciotomy Incisions in the Lower Leg: Do We Need to Change Our Strategy?

Objectives: The primary purpose of this study is to determine whether a strategy of bringing patients back to the operating room for successive debridements allows for the eventual delayed primary closure (DPC) of fasciotomy wounds.

Design: Retrospective cohort study. Data were collected from medical records and radiographs.

Does fluoroscopy improve acetabular component placement in total hip arthroplasty?

Background: The success of THA largely depends on correct placement of the individual components. Traditionally, these have been placed freehand using anatomic landmarks, but studies have shown poor accuracy with this method.

Questions/purposes: Specifically, we asked (1) does using fluoroscopy lead to more accurate and greater likelihood of cup placement with the Lewinnek safe zone than does freehand cup placement; (2) is there a learning curve associated with the use of fluoroscopy for cup placement; (3) does the use of fluoroscopy increase operative time; and (4) is there a difference in leg length discrepancy between freehand and fluoroscopic techniques?

Methods: This series consisted of 109 consecutive patients undergoing primary THA, conversion of a previous hip surgery to THA, and revision THA during a 24-month period.

Effect of surgical treatment on mortality after acetabular fracture in the elderly: a multicenter study of 454 patients.

Objectives: Controversy exists regarding the effect of operative treatment on mortality after acetabular fracture in elderly patients. Our hypothesis was that operative treatment would confer a mortality benefit compared with nonoperative treatment even after adjusting for comorbidities associated with death.

Design: Retrospective study.

Predictive factors of distal femoral fracture nonunion after lateral locked plating: a retrospective multicenter case-control study of 283 fractures.

Introduction: Reported initial success rates after lateral locked plating (LLP) of distal femur fractures have led to more concerning outcomes with reported nonunion rates now ranging from 0 to 21%. Reported factors associated with nonunion include comorbidities such as obesity, age and diabetes. In this study, our goal was to identify patient comorbidities, injury and construct characteristics that are independent predictors of nonunion risk in LLP of distal femur fractures; and to develop a predictive algorithm of nonunion risk, irrespective of institutional criteria for clinical intervention variability.
