Abstract

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), under- going 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.
