摘要目的：本回顾性研究的目的是报道骨溶解的发生率，并评估筛查计算机断层扫描（CT）与x线平片相比在检测金属-高交联聚乙烯全髋关节置换术后骨溶解的意义。方法：回顾性分析264例原发性无骨水泥全髋关节置换术211例患者，其中男性24例，女性187例，均在术后7-10年（平均8.2年）接受CT扫描和x线摄影。第一代高交联聚乙烯在所有情况下都使用。结果：随访期间平片未见髋臼骨溶解（0%），股骨骨溶解2例（0.8%）。CT扫描未发现新骨溶解。结论：高交联聚乙烯全髋关节置换术术后7-10年骨溶解发生率极低，本研究不支持常规筛查CT扫描检测骨溶解。
Abstract Objectives: The purpose of this retrospective study is to report the incidence of osteolysis and evaluate the significance of screening computed tomography (CT) compared to plain radiography in detecting osteolysis after total hip arthroplasty with metal-on-highly cross-linked polyethylene bearings. Methods: We retrospectively reviewed 264 primary cementless total hip arthroplasties of 211 patients, 24 males, 187 females, who received postoperative screening CT scan in addition to radiography at postoperative 7–10 years (average 8.2 years). First-generation highly cross-linked polyethylene was used in all cases. Results: On the plain radiographs, no acetabular osteolysis (0%) and two cases of femoral osteolysis (0.8%) were found in the follow-up period. No osteolysis was newly found by screening CT scan. Conclusions: Very low incidence of osteolysis after total hip arthroplasty with highly cross-linked polyethylene at postoperative 7–10 years was confirmed, and routine screening CT scan for detecting osteolysis in this setting was not supported from this study.
