A retrospective analysis of 63 primary total hip arthroplasty cases was done using repeated computed tomography scans to evaluate the pelvic osteolytic lesions in early stage. The progression rate of osteolysis of hips with small osteolytic volume less than 766.97 mm(3) in initial CT was 85.82 mm(3)/year, and that of hips with osteolysis more than 766.97 mm(3) was 456.3 mm(3)/year (P < 0.001). Younger patients less than 52 years old with good Harris Hip Scores (more than 80) frequently showed much faster progression in volume of osteolytic lesions. The rate of osteolysis was accelerated when the amount of osteolysis reached a certain threshold volume in active young patients in a cascade manner even in early stage.
对 63 例初次全髋关节置换术病例进行了回顾性分析，使用重复 CT 扫描来评估早期的骨盆溶骨性病变。在初始 CT 中，小溶骨量（小于 766.97mm³）的髋关节骨溶解进展率为 85.82mm³/年，而溶骨量大于 766.97mm³的髋关节骨溶解进展率为 456.3mm³/年（P<0.001）。年龄小于 52 岁且 Harris 髋关节评分良好（大于 80）的年轻患者，其溶骨病变体积的进展速度通常更快。在早期，即使是在活跃的年轻患者中，当溶骨量达到一定的阈值体积时，溶骨的速度也会呈级联方式加速。
