双动人工股骨头与全髋关节置换治疗高龄股骨颈骨折的疗效比较

目的 比较双动人工股骨头置换与全髋关节置换治疗高龄股骨颈骨折的疗效，明确双动人工股骨头置换治疗高龄股骨颈骨折的优越性。方法 对1996年1月-2000年1月采用人工髋关节置换治疗的高龄股骨颈骨折87例进行回顾性分析，其中双动人工股骨头置换(FHR)56例，平均随访4年1个月，全髋关节置换(THR)31例，平均随访4年3个月。结果 FHR组术中出血量明显少于THR组，手术时间明显短于THR组，术后早期并发症的发生率明显少于THR组，且两组Harris功能评分无明显差异。结论 高龄股骨颈骨折采用双动人工股骨头置换的手术安全性高，术后并发症少，关节功能好，疗效满意，应优先选用。

Comparative analysis of bipolar femoral head replacement and total hip replacement for the treatment of femoral neck fractures in the elderly

Objective: To compare the effect of bipolar femoral head replacement (FHR) and total hip replacement (THR) for the treatment of femoral neck fractures in the elderly Methods: From January 1996 to January 2000,87 patients over 75 years old with displaced femoral neck fractures were analyzed postoperatively.56 cases were treated with FHR and followed up for the average of 4 years and 1 month,31 cases with THR and followed up for 4 years and 3 months.Results: The bleeding volume of FHR group was significantly lower than that of THR group during operation and the operative time of FHR was significantly shorter than THR group.The early complication after FHR was significantly less than after THR and the Harris score in follow-up was no different between two groups.Conclusion: The bipolar femoral head replacement is safe and satisfactory method,which will be the first choice for the treatment femoral neck fractures in the elderly.
