The Effect of Obesity on Hemiarthroplasty and Total Hip Arthroplasty for Femoral Neck Fractures.

Obesity is a well-recognized global epidemic that can lead to longer operative times as well as a greater technical demand. Despite this, the available literature evaluating the impact of obesity on hip hemiarthroplasty (HA) and total hip arthroplasty (THA) when treating fractures about the femoral neck is scarce. Between 2015 and 2018, we retrospectively reviewed all patients that had a HA or THA performed as treatment for an isolated fracture of the femoral neck. Patients were classified as obese and nonobese depending on current body mass index (BMI) when the index procedure was performed. Preoperative and postoperative variable were obtained from the electronic medical record. A total of 157 patients underwent hip HA or THA for an isolated fracture of the femoral neck. In those patients undergoing HA, obesity was associated with an increase in operative times (P = 0.021) and was associated with a nonsignificant increase in total operating room time (P = 0.088) and duration of anesthesia (P = 0.14). In those patients undergoing THA, obesity was associated with longer operative times (P = 0.043), total operating room time (P = 0.032), and duration of anesthesia (P = 0.045). There were no significant differences in complication rates postoperatively between obese and non-obese patients undergoing either procedure. The treatment of isolated fractures of the femoral neck with HA or THA leads to an increase in operative time without an increase in postoperative complications in obese patients.

Early Definitive Fixation of Talus Fractures Is Safe: A Retrospective Review.

BACKGROUND: Talus fractures are often result of high energy mechanisms and can lead to devastating complications. Treatment is often operative; however, the appropriate timing of this has been debated. The purpose of this study is to determine the efficacy and safety of the early treatment of talus fractures. METHODS: Patients aged 18 years or older who underwent definitive operative stabilization of their talus fracture at a single urban level 1 trauma center were retrospectively reviewed. Patients were split into 2 groups based on their time to definitive fixation: ≤ or >24 hours. Pertinent demographic, surgical, and follow-up data were collected and analyzed. RESULTS: A total of 108 fractures were treated with 65 in the ≤24 hours fixation group and 43 in the >24 hours fixation group. Fractures involving the talar neck were the most commonly treated fracture pattern followed by the body and the head. There was no difference between the 2 groups in length to full weight bearing, union, or time to union. Open fracture was found to be the only significant risk factor for nonunion in both groups. There was no significant difference in infection or arthrodesis rates between the 2 groups. CONCLUSION: Definitive treatment of talus fractures within 24 hours from presentation is both safe and effective with equal outcomes and without increased complications when compared with those injuries that undergo delayed or staged definitive fixation. LEVEL OF EVIDENCE: Level III.
