Hemiarthroplasty is a common treatment for fracture neck of femur in elderly patients. Unipolar hemiarthroplasty has shown good results, though there is high incidence of erosion, protrusion and needs revision in future. The concept of dual bearing surfaces results in sharing of motion at the two surfaces and hence reduction of net wears at either surface, thus reducing erosion at the acetabular-joint interface. From our relatively short term prospective nonrandomized study, we conclude that bipolar hemiarthroplasty gives good results.
