Abstract
OBJECTIVES: Describe the incidence of venous thromboembolism (VTE) in patients with pelvic and lower extremity long bone trauma in the setting of modern prophylaxis. DESIGN: Retrospective health-system database study. SETTING: Multi-center health care system. PATIENTS: Database query from 2010 to 2017 identified 11,313 adult trauma patients who received open reduction internal fixation of pelvic, acetabular, femoral neck, or intertrochanteric fractures, or received intramedullary nailing (IMN) of the femoral or tibial shaft. Patients with incomplete prophylaxis, prior history of VTE, coagulopathy, or concomitant lower extremity fracture were excluded. INTERVENTION: Mechanical and chemical VTE prophylaxis following pelvic or lower extremity fracture fixation. MAIN OUTCOME MEASUREMENTS: VTE rates. RESULTS: The overall VTE rate was 0.82% [0.39% deep venous thromboses (DVT); 0.43% pulmonary emboli (PE)]. By procedure, pelvic open reduction and internal fixation (ORIF) and femoral IMN had the highest VTE rates 1.70% (0.98% DVT; 0.78% PE) and 1.33% (0.75% DVT; 0.58% PE), whereas tibial IMN had the lowest incidence of VTE 0.34% (0.17% DVT; 0.17% PE). Among hip fractures, femoral neck ORIF had a VTE rate of 0.98% (0.59% DVT; 0.39% PE), whereas intertrochanteric ORIF had lower rates of 0.59% (0.20% DVT; 0.39% PE). CONCLUSIONS: Despite adherence to modern VTEp protocols, nonpreventable VTE occur in 0.82% of pelvic and lower extremity orthopaedic trauma patients. Incidence ranged between 0.34% and 1.70% depending on injury/fixation method with the highest rate observed in pelvis ORIF followed by femoral IMN. In the era of pay for quality performance, it is important for health systems and auditing agencies to reconcile the difference between preventable and nonpreventable VTEs. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
