Thirty-one patients with unstable displaced pelvic or acetabular fractures were admitted and underwent an open reduction and internal fixation of their fracture. All patients were studied prospectively for the incidence of proximal deep vein thrombosis (DVT) utilizing venous duplex ultrasound. Duplex scans were repeated at 1 week postoperatively in all patients. Additional scans were performed when clinically indicated. A total of 61 scans were completed. DVT developed in three patients (approximately 10%). Two of the three positive scans were noted only on postoperative examination. The third scan was positive on the preoperative phase. Duplex ultrasound was easily applied and well tolerated by the multiply injured patient.
31例不稳定型移位骨盆或髋臼骨折患者入院并接受了骨折切开复位内固定术。所有患者均采用静脉双功超声对近端深静脉血栓形成（DVT）的发生率进行前瞻性研究。所有患者术后1周重复进行双功扫描。临床有指征时进行额外扫描。共完成61次扫描。3例患者发生DVT（约10%）。3例阳性扫描中有2例仅在术后检查时发现。第3次扫描在术前阶段为阳性。双功超声易于应用，且多重受伤患者耐受性良好。
