Abstract：
We report a patient with intrapelvic prosthetic protrusion associated with infection after hemiarthroplasty for a fracture neck of the femur. We discuss the challenges involved in the management of this complex case with recommendations to manage a vascular injury.
In patients with an intrapelvic prosthesis, thorough preoperative vascular evaluation and vigilant postoperative check are required to prevent a vascular injury. In a suspected vessel injury after primary or revision total hip arthroplasty, it is imperative to get proximal control of the vessel before re-exploration. A combined arterial Doppler and computerized tomography angiogram is more reliable in picking up arterial impingement by acetabular screws.

摘要：
方法：我们报告了1例股骨颈骨折半髋关节置换术后合并感染的患者。我们讨论了处理这一复杂病例所面临的挑战，并提出了处理血管损伤的建议。
结论：在使用骨盆内假体的患者中，全面的术前血管评估和警惕的术后检查是必要的，以防止血管损伤。在初次或翻修全髋关节置换术后疑似血管损伤中，在重新探查之前，必须对血管进行近端控制。合并的动脉多普勒和计算机断层扫描血管造影在通过髋臼螺钉拾取动脉撞击时更可靠。
