颗粒骨植骨在人工髋关节置换术中的应用

目的 探讨颗粒骨植骨在人工髋关节置换术中的应用效果。方法对16例（18髋）合并骨质疏松者行人工髋关节置换术，术中将切下的股骨头及股骨颈松质骨制成1～3mm颗粒骨打压植入股骨髓腔，同时安放假体。结果18例均获随访，时间6—63个月，Harris评分从术前的22～59（45．7±0．3）分提高到最后评估时的73～96（85．3±0．2）分。X线片未见有明显的股骨假体下沉。结论骨质疏松患者行人工髋关节置换术中进行颗粒骨打压植骨疗效满意，中、短期的临床效果良好，长期效果有待进一步观察。

Morselized bone grafting in the hip arthroplasty

Objective To explore the effect of morselized bone grafting in hip arthroplasty. Methods 16 cases （ 18 hips） with osteoporosis were undergone hip arthroplasty. The spongy bone of femur head and femur neck was made into morselized bone of 1 - 3 ram, and impacted into femoral cavity. Results The mean Harris Hip Score was improved from 22 - 59 （45.7 ± 0. 3 ） points p,＇eoperatively to 73 - 96 （ 85.3±0. 2） points at final evaluation. No femoral stem subsidence was found. Conclusions The morselized bone impavtion grafting in artificial hip replacement is an attractive procedure for patients with osteoporosis and the short and mid-term results are good. Longer follow-up is needed to evaluate the long term result.
