We have followed up a series of total hip arthroplasties performed for secondary osteoarthritis and analysed the results in relation to the osteoblastic response to the disease. This was assessed pre-operatively from the radiographic appearance, according to Bombelli's criteria (1983). Of 63 hips in 55 patients followed up for five to 13 years, 17 were hypertrophic, 24 normotrophic and 22 atrophic in type. The atrophic-type hips showed a high incidence of acetabular loosening, leading to unsatisfactory clinical results in 32%. By contrast, the hypertrophic-type hips had a low incidence of acetabular loosening, while the normotrophic type showed intermediate results. It was concluded that the osteoblastic response to osteoarthritis is closely related to acetabular loosening and to late clinical failure.
我们对一系列因继发性骨关节炎而进行的全髋关节置换术进行了随访，并分析了与疾病成骨反应相关的结果。术前根据Bombelli标准（1983年）通过影像学表现对此进行评估。在55例患者的63个髋关节随访5至13年的过程中，17个为肥厚型，24个为营养正常型，22个为萎缩型。萎缩型髋关节髋臼松动发生率高，32%的临床结果不理想。相比之下，肥厚型髋关节髋臼松动发生率低，而营养正常型则表现为中等结果。得出的结论是，骨关节炎的成骨反应与髋臼松动及晚期临床失败密切相关。
