Venous Thromboembolism Prophylaxis After Pelvic and Acetabular Fractures: A Survey of Orthopaedic Surgeons' Current Practices.

Introduction: The goal of this study was to identify the current practices and rationale of orthopaedic surgeons regarding venous thromboembolism (VTE) prophylaxis for pelvic and acetabular (P&A) fractures.

Methods: A 25-item web-based questionnaire was made available to all Orthopaedic Trauma Association (OTA) members on the OTA website. Analysis of data was performed after the three-month study period.

Results: One hundred three active OTA members completed the survey. Most respondents practiced at an academic level I trauma centers. The most important factor in selecting a VTE regimen was its effectiveness, whereas cost was the least important. Low-molecular-weight heparin (LMWH) remains the preferred agent for VTE prophylaxis after P&A trauma. Factors such as surgical intervention and weight-bearing had a variable effect on surgeons' opinions regarding the type and duration of VTE prophylaxis.

Conclusion: Most surgeons treating P&A fractures use LMWH for VTE prophylaxis, but the decision on which agent to use and duration of treatment is multifactorial. Published VTE prophylaxis literature and guidelines provide some guidance, but there is no consensus. Overall, LMWH appears to be the VTE prophylaxis agent of choice for most orthopaedic trauma surgeons, irrespective of nonsurgical or surgical management of these fractures.
