摘要 目的：研究骨基质明胶(BMG)防治人工关节无菌性松动的可行性。方法：制备兔BMC及陶瓷人工股骨头。大白兔40只，随机分成两组，行右人工股骨头置换，一组植入BMC，另一组不植BMC作为对照，并以不同时期作生物力学测定、组织学检查、立体显微摄影和电子探针检测，以了解人工关节周围的成骨情况。结果：BMG组各时期拔出强度明显高于对照组。BMG组人工关节周围成骨速度及骨量明显高于对照组。结论：BMG能加速骨组织与人工关节的结合，可加速人工关节的生物学固定，防止无菌性松动的发生。关键词 骨基质；明胶；人工关节；实验

Abstract Objective：To prevent aseptic koosening after artificiak joint repkacement by bone matrix gekatin(BMG).Methods:BMG and rabbit prosthes is of femorak head were made.Forty rabbits，operated on them for right artificiak repkacement，were divided randomky into two groups.BMG was impkanted into rabbit prothesis in one group ......
