The use of custom-manufactured femoral prostheses as part of routine total hip arthroplasty (THA) has been suggested. However, there are several disadvantages, including possible inaccuracy of fit, inadequate instrumentation, and high cost. A series of 28 THAs (including 18% for revision of failed, cemented THA) using a press-fit prosthesis of contemporary design were investigated. The average follow-up period was 28 months (range, 12-49 months). Clinical results were overall very good, even in revision cases. Roentgenographic changes included rapid femoral remodeling, which may increase component stability. Given the clinical and roentgenographic results obtained in this complex-problem patient population, it is difficult to justify the use of custom femoral components in routine THA.
有人建议在常规全髋关节置换术（THA）中使用定制制造的股骨假体。然而，存在几个缺点，包括可能的贴合不准确、器械不足和成本高昂。对一系列28例使用当代设计的压配假体的THA（包括18%用于翻修失败的骨水泥型THA）进行了研究。平均随访期为28个月（范围为12至49个月）。临床结果总体非常好，即使在翻修病例中也是如此。X线片变化包括股骨快速重塑，这可能会增加假体稳定性。鉴于在这一复杂问题患者群体中获得的临床和X线片结果，在常规THA中使用定制股骨组件难以得到合理的解释。
