摘要
目的 研究人工全关节置换术后股骨近端骨溶解问题。方法 对52例患者56髋进行随访，男性组26例28髋，女性组26例28髋，两组患者在年龄、所用假体、术前诊断方面采用匹配性研究。最短随访时间9个月，最长10年6个月。并用计算机图像分析的方法定量研究骨密度改变的规律。结果 52例（56髋）患者股骨近端均发生不同程度骨溶解，最早术后9个月，术后1-5年内骨溶解改变最明显，第6年呈减缓趋势。结论 人工全髋关节置换术后骨溶解在男性以及女性患者中都存在，二者无显著差异（P〉0．05）。
Objective To investigate the prevalence of femoral osteolysis in total hip replacement, Methods The prevalence of femoral osteolysis in male patients was compare with female patients , in a retrospective matched-pair study of the results of primary total hip arthroplasty ,fifty six hips in fifty two patients who had a Harris-Galant porous-coated total hip prosthesis in age ,kinds of component, duration of following up and diagnosis, Regular pattern of the bone density of the proximal femur was quantitatively determined by using computer image analysing. Results Osteolysis developed in all patients （100 percent）. Obvious osteolysis appeared one or five years after operation,and lessened at the sixth year. Conclusion The prevalence of femoral osteolysis associated with male patients or female patients in total hip replacement. No significant difference is observed in two groups of patients.
