In the development of cementless hip prosthesis, first generation cementless femoral component become major concerned that included increase risk of stress-related bone resorption, thigh pain, osteolysis and component instability. So required more improved femoral component design features addressing these problems.
Multilock cementless femoral stem design is changed for increasing stability with distal locking, avoiding stress shielding by increasing implant flexibility, promoting long-term implant performance compared to first generation cementless stem. The purpose of this study was to evaluated the short term result of Multilock cementless femoral stem.
We analyzed 33 cases of Multilock cementless hip replacement in 27 patients performed at the Department of Orthpaedic Surgery, College of Medicine Soonchunhyang University, from December 1991 to June 1993. The follow-up period more than 1 year, the average being 21 months. And authors report clinical & radiographic analysis of this study. the results were as follows.
1. The causes were avascular necrosis in 28 cases(85%), degenerative osteoarthritis in I case(3%), fracture of femur neck in 2 cases(6%), traumatic arthritis in 1 case(3%), acetabular fracture in I case(3%).
2. The average Harris hip score improved from 47.8 preoperatively to 91.6 in one year follow-up and 95.5 in two year follow-up.
3. Complication were intraoperative linear fracture in 3 hips, dislocation of prosthesis in 2 hips.
4. In radiographic analysis, a radio dense femoral line was found in 9 hips(27%), it was not always
