We prospectively assessed the results of 239 primary total hip replacements performed using a conical stem combined with modular necks of different lengths and inclinations (Modulus System, Lima Corporate San Daniele Del Friuli, Udine, Italia) in 222 patients (50 men, 172 women), undergoing surgery between October 2001 and December 2006 and presenting with anatomical deformities of the proximal femur and/or acetabulum, including developmental dysplasia (DDH), ankylosis, and sequelae of osteotomies or fractures. Such conditions can make hip replacement problematic. The mean age at the time of surgery was 57.6 years (22 ÷ 83). No patients were lost to follow-up. 3 femoral components underwent revision. At a mean of 5 years follow-up the Harris Hip Score showed a significant improvement, increasing from 35 preoperatively to a mean of 96.6. Using Kaplan-Meier analysis the survival rate at 5 years was 98.28%. The Modulus stem showed good mid-term results in terms of survival, as well as clinical and radiographic outcome.
我们前瞻性评估了2001年10月至2006年12月期间，对222例患者（50例男性，172例女性）进行的239例初次全髋关节置换术的结果。这些患者存在股骨近端和/或髋臼的解剖畸形，包括发育性髋关节发育不良（DDH）、关节强直以及截骨术或骨折的后遗症。此类情况会使髋关节置换术面临问题。手术时的平均年龄为57.6岁（22至83岁）。无患者失访。3个股骨组件进行了翻修。平均随访5年时，Harris髋关节评分显示有显著改善，从术前的35分提高到平均96.6分。使用Kaplan-Meier分析，5年生存率为98.28%。Modulus柄在生存率以及临床和影像学结果方面显示出良好的中期效果。
