In a series of 100 total hip arthroplasties revised due to various noninfectious causes, intraoperative determinations of the stability of the socket were compared with conventional preoperative radiographs. All seven hips without radiolucency around the cemented socket were found to be stable. Loosening was demonstrated in 6%-31% of the hips with radiolucency, depending on the classification system. Significantly, 35% of sockets with radiographic signs of migration were found to be stable. Radiographic evaluations of socket stability are difficult and require serial images obtained in precisely defined positions.
在因各种非感染性原因而翻修的100例全髋关节置换术中，将髋臼稳定性的术中测定结果与传统术前X线片进行了比较。发现所有7例骨水泥固定髋臼周围无透亮线的髋关节均稳定。根据分类系统，在有透亮线的髋关节中，6%-31%显示有松动。值得注意的是，35%有影像学移位征象的髋臼被发现是稳定的。髋臼稳定性的影像学评估很困难，需要在精确界定的位置获取系列图像。
