In ten- to 18-year clinical and roentgenographic results of 46 cemented total hip arthroplasties (THAs) in 34 patients younger than 50 years of age, surviving primary implants achieved a mean Harris hip score of 93 points. Survivorship analysis revealed failure rates of 2% at seven years, 10% at ten years, and 12.7% at 12 years. Roentgenographic analysis demonstrated either no signs of failure or benign mechanical failure modes in 73% of cases. No correlation was found between the Charnley category or the diagnosis and the clinical or the roentgenographic assessments. Cemented THA in the young would appear to provide durable restoration of hip function, with a revision rate similar to that reported in the elderly. For reliable early detection of progressive mechanical failure before loss of bone stock occurs, annual roentgenographic examinations are advisable.
在对34名年龄小于50岁的患者进行的46例骨水泥型全髋关节置换术（THA）的10至18年临床和X线结果中，存活的初次植入物的Harris髋关节平均评分为93分。生存分析显示，7年时失败率为2%，10年时为10%，12年时为12.7%。X线分析表明，73%的病例无失败迹象或为良性机械性失败模式。未发现Charnley分类或诊断与临床或X线评估之间存在相关性。年轻患者的骨水泥型THA似乎能持久恢复髋关节功能，翻修率与老年人报告的相似。为了在骨量丢失之前可靠地早期检测进行性机械性失败，建议每年进行X线检查。
