A study of hip arthroplasty using bipolar endo-prothesis for fracture neck of femur

The first efforts on treating hip fractures concentrated on alignment of fracture fragments by traction and closed reduction. The reduction was maintained by long term traction, spica casts or internal fixation. However, despite the most accurate anatomic alignment and most rigid fragment fixation, many patients failed to regain normal use of their hips. Non-union of the femoral neck, avascular necrosis of the femoral head and the degree of fracture commination affected results in many. Nonanatomic reduction and inadequate fixation cause prolonged disability, pain, immobility and repeated surgical procedures.
