Seventy-seven total hip arthroplasty procedures performed between 1982 and 1989 for osteoarthritis by the same surgeon using a cementless acetabular component were reviewed retrospectively after a mean follow-up of 3.5 years. Clinical outcomes were similar to those seen with cemented implants. Roentgenographic analysis of acetabular position detected migration of 19 implants (25%). Actuarial survival analysis showed that the migration-free survival rate of acetabular components was 74.5% nine years after insertion. Bony consistency of the acetabulum after reaming was the only factor that significantly influenced the likelihood of acetabular component migration. Increased acetabular density after previous conservative hip surgery was associated with a significant reduction in the risk of migration (p = 0.003). Because anchorage quality was not predictable, we discontinued use of cementless acetabular components.
回顾性分析了1982年至1989年间，同一位外科医生使用非骨水泥髋臼假体为骨关节炎患者实施的77例全髋关节置换手术，平均随访3.5年。临床结果与使用骨水泥假体相似。髋臼位置的X线分析发现19枚假体（25%）发生移位。精算生存分析显示，髋臼假体植入9年后无移位生存率为74.5%。扩髓后髋臼的骨质情况是显著影响髋臼假体移位可能性的唯一因素。既往保守性髋关节手术后髋臼密度增加与移位风险显著降低相关（p = 0.003）。由于锚固质量不可预测，我们停止使用非骨水泥髋臼假体。
