[Biomechanical principles, indications and early results of bipolar hip arthroplasty].
The authors present indications and early results of bipolar hip arthroplasty in 58 patients (46 females, 12 males) aged 38-84 (mean 65 years). Femoral neck fracture in 51 patients, femoral neck pseudoarthrosis in 3, pathological fracture of the femoral neck in 2 and early type of hip osteoarthritis constituted the indication for bipolar hip replacement. No infection or dislocation has occurred. Mean follow-up was 1.5 years (6-36 months). Revision of the replacement was necessary in one patient due to faulty size of chosen implant. Results in remaining patients were rated excellent to good (mean Harris Hip Score was 93 points) with great range of movement in the operated hip. No signs of acetabular cartilage deterioration or prosthetic protrusion was observed.
