Clinical & radiological analysis of results of primary hemiarthroplasty using cemented bipolar modular prosthesis in fracture neck of femur

Abstract

Single assembly total hip prosthesis, which sought to provide a completely mobile head elements and an additional head surface to allow movement within the acetabulum. Thus he aimed to create a compound system providing for a greater distribution of bearing forces, which could minimize wear both on implant and on articular cartilage, it was proved to have greater stability and decreased chances of dislocation and increased range of motion compared to unipolar prosthesis. Finally it was expected that bipolar arthroplasty could be more easily revised than total hip arthroplasty in cases of acetabular deterioration.
