To present initial experience of the first 71 cases of cementless total hip replacement in Al Razi Hospital.
Between 1996 and 2004, total hip replacement was performed in 71 patients (40 male, 31 female, average age 40.7 years, range 17-74) using Zweymüller cementless prosthesis. The patients were followed clinically and radiologically over an average period of 36 months (range 6-84). The results were assessed according to Merle d'Aubigne clinical score. Radiological assessment included position of the implant, behavior of the prosthesis/bone interface and signs of osteointegration.
Average clinical score during the 3 years' follow-up period was 17.8 points. Most of the implants were in optimal positions. No significant radiological modifications of the implant-bone interface were observed.
Zweymüller total hip prosthesis gives excellent clinical and radiological results in short-term follow-up.
