Femoral neck fractures are an ever-increasing pathology, and with the elderly population on the rise, cases of cemented bipolar hemiarthroplasties are also on the rise. This is a rare case of intraoperative dissociation and migration of the trial components of bipolar hemiarthroplasty. Considering the current literature, all junior surgeons should be aware of this possible development during trial reduction. We present the case of an 82-year-old Caucasian woman suffering from a left femoral neck fracture due to a fall. She was treated surgically with a cemented bipolar hemiarthroplasty, but after trial reduction, the trial components dissociated and migrated inside the pelvis. The attempts at recovery through the current approach failed, and a new incision and approach were needed. A small ilioinguinal incision was performed, and the recovery of the trial cup was successful. The patient recovered with no considerable problems. As the reasons for this rare complication are largely unknown, the surgeon should be careful and take measures to prevent this scenario. Moreover, it is wise to weigh the pros and cons of retrieval through other approaches and choose the best course of action for the patient.
股骨颈骨折是一种日益常见的病症，随着老年人口的增加，骨水泥型双极半髋关节置换术的病例也在增多。这是一例双极半髋关节置换术试验组件术中分离和移位的罕见病例。鉴于当前的文献资料，所有初级外科医生在进行试验复位时都应意识到这种可能出现的情况。我们报告一例82岁白种女性因跌倒导致左股骨颈骨折的病例。她接受了骨水泥型双极半髋关节置换术，但在试验复位后，试验组件在骨盆内分离并移位。通过当前方法进行恢复的尝试失败了，需要新的切口和手术入路。实施了一个小的髂腹股沟切口，成功找回了试验髋臼杯。患者顺利康复，没有出现重大问题。由于这种罕见并发症的原因大多未知，外科医生应谨慎并采取措施预防这种情况。此外，权衡通过其他方法找回组件的利弊并为患者选择最佳行动方案是明智的。
