Digital radiographic images in the anterior-posterior and lateral view have been gold standard for evaluation of peri-acetabular osteolysis for patients with an uncemented hip replacement. We compared digital radiographic images and computer tomography in detection of peri-acetabular osteolysis and devised a classification system based on computer tomography. Digital radiographs were compared with computer tomography on 206 hips, with a mean follow up 10 years after surgery. The patients had no clinical signs of osteolysis and none were planned for revision surgery. On digital radiographs, 192 cases had no osteolysis and only 14 cases had osteolysis. When using computer tomography there were 184 cases showing small or large osteolysis and only 22 patients had no osteolysis. A classification system for peri-acetabular osteolysis is proposed based on computer tomography that is easy to use on standard follow up evaluation.
数字 X 光前后位和侧位片一直是评估非骨水泥髋关节置换术后髋臼周围骨溶解的金标准。我们比较了数字 X 光片和计算机断层扫描在检测髋臼周围骨溶解中的作用，并基于计算机断层扫描制定了一个分类系统。对 206 髋进行了数字 X 光片和计算机断层扫描比较，术后平均随访 10 年。这些患者没有骨溶解的临床症状，也没有计划进行翻修手术。在数字 X 光片上，192 例无骨溶解，仅 14 例有骨溶解。使用计算机断层扫描时，有 184 例显示小或大的骨溶解，只有 22 例无骨溶解。我们提出了一个基于计算机断层扫描的髋臼周围骨溶解分类系统，该系统易于在标准随访评估中使用。
