BACKGROUND
Ceramic bearings in total hip arthroplasty (THA) have been introduced in clinical practice to minimize the problem of polyethylene particle-induced osteolysis. The aim of the study is to report the results of 68 consecutive alumina-on-alumina THAs done in 61 patients for avascular necrosis (AVN) of the femoral head.
MATERIALS AND METHODS
In all implants a press-fit cup was used; it was combined with a 32-mm alumina head and with titanium-alloy stems. The mean age at surgery was 50 years. At an average follow-up of 13 years two hips have been revised, one for periprosthetic infection and one for excessive abduction of the cup.
RESULTS
No revision for aseptic loosening is recorded; one anatomical cementless femoral stem had radiological evidence of definite aseptic loosening. No dislocations occurred, and no osteolysis was observed.
CONCLUSIONS
The results support the application of alumina-alumina THA for long-lasting replacements.
背景
全髋关节置换术中使用陶瓷轴承已在临床实践中得到应用，以最大程度地减少聚乙烯颗粒引起的骨溶解问题。本研究的目的是报告在 61 例因股骨头缺血性坏死（AVN）而接受 68 例氧化铝-氧化铝全髋关节置换术（THA）的连续结果。
材料和方法
所有植入物均使用压配合杯，与 32mm 氧化铝头和钛合金柄组合使用。手术时的平均年龄为 50 岁。平均随访 13 年后，有 2 髋进行了翻修，1 例因假体周围感染，1 例因髋臼过度外展。
结果
未记录到无菌性松动的翻修；1 例解剖型非骨水泥股骨柄有明确无菌性松动的影像学证据。未发生脱位，也未观察到骨溶解。
结论
结果支持氧化铝-氧化铝 THA 用于长期置换。
