The bipolar endoprosthesis (Hastings hip) operations performed in 41 hips between 1985 to 1990 were retrospectively reviewed.There were 31 cases of femoral neck fractures, 5 cases of aseptic necrosis of the femoral head and 5 cases of osteoarthritis.The mean age at surgery was 77.0 years (ranging from 65 to 87).The follow up period was 3.2 to 9.3 years postoperatively (mean 5.6 years).Preoperative complications were seen in 68.3% and the survival rate was significantly lower in such cases.The average JOA score was 81.0, while in osteoarthritic cases this was 74.6 showing a statistical difference between these two groups (p<0.05).The rate of survival, analysed according to Kaplan-Meier's method shows that the cumulative population was 91.2% after five years, declining to 80.2% ten years postoperatively.The Hastings hip system is more simple, reliable and cheaper than other bipolar prosthesis systems. We consider that the Hastings hip is a good choice for elderly patients with a femoral neck fracture.
