Total hip arthroplasty (THA) is a safe and reliable surgical procedure. However, THA also has intra- and postoperative complications. A dreaded and frustrating intraoperative complication during total hip arthroplasty is dislocation of the femoral trial head from the neck into the pelvis.
Here, we report on the case of a 71-year old female patient with osteoarthritis of the left hip. Total hip arthroplasty was performed in a lateral position through a standard posterior approach. During intraoperative trial reduction, the femoral trial head dissociated from the taper and dislocated into the psoas compartment. Several unsuccessful attempts, including an additional ventral approach, were made to immediately retrieve the femoral trial head.
Postoperative a Computerized Tomography (CT) was performed to locate the trial head, a secondary explorative laparotomy was undertaken to retrieve it. The retrieval of the femoral trial head should be performed in a planned second surgical procedure to avoid possible complications during the manipulation necessary for retrieval.
全髋关节置换术（THA）是一种安全可靠的外科手术。然而，THA也存在术中及术后并发症。全髋关节置换术中一种可怕且令人沮丧的术中并发症是股骨试验头从颈部脱位进入骨盆。
在此，我们报告一例71岁左髋骨关节炎女性患者的病例。通过标准后外侧入路在侧卧位下行全髋关节置换术。术中试行复位时，股骨试验头从锥度处分离并脱位至腰大肌间隙。进行了几次尝试，包括额外的前路入路，试图立即找回股骨试验头，但均未成功。
术后进行计算机断层扫描（CT）以定位试验头，并进行了二次探查性剖腹手术以找回试验头。应在计划好的第二次手术中进行股骨试验头的找回，以避免在找回所需操作过程中可能出现的并发症。
