缝匠肌骨瓣移植空心拉力钉固定治疗青壮年股骨颈骨折

目的：通过采用缝匠骼骨瓣移植、空心拉力钉固定治疗青壮年股骨颈骨折,获得更好的疗效。方法：自１９９２年１月～１９９９年１２月,采用缝匠肌骨瓣移植桥接与空心拉力钉固定治疗青壮年股骨颈骨折,随访时间１～５年,平均４年。结果：７３例新鲜骨折中１例骨折不愈合,股骨头坏死,１例骨折愈合股骨头坏死;２７例移位型陈旧骨折中３例骨折不愈合,股骨头坏死,２例骨折愈合后股骨头坏死。骨折愈合率９６％,股骨头坏死率７％。结论：缝匠肌骨瓣移植可改善股骨头血供并使植骨以“活骨骨折愈合”的方式完成,陈旧性骨折股骨颈吸收的可重建股骨颈,井有一定的强度支撑防止股骨头坏死应力塌陷,与空心拉力钉有协同支撑固定作用。三根空心拉力钉固定创伤小而连接控制面积大是理想的内固定物。

Fixed treatment for femoral neck fracture of young adults by bone flap M. sartorious transplanting and hollow pulling nails

Objective: To achieve better effects through the application of bone flap M. Sartorious transplanting and hollowpulling nails for the treatment of the femoral neck fracture of young adults. Methods: From 1,1992 to 12, 1999, We treatedfemoral neck fracture of young adults by bone flap M. Sartorious transplanting and hollow pulling nails with one to five yearsfollow-up,averaging 4 years. Results: Among 73 fresh (new) fracture 1 not healed up,femoral head necrosis, 1 healed up, withtemoral head necrosis;27 transferred old fractures, 3 not healed up, femoral head necrosis, 2 healed up, femoral head necrosis.Fracture healing rate was 96 percent, femoral head necrosis rate was 7 percent. Conclusion: That the bone flap M. Sartorioustransplanting can improve femoral blood supply, finish bone transplanting in a way of"live bone fracture healing up", rebuildfemoral neck for old fracture and together with hollow pulling nails prevent femora from necrosis. Three hollow pulling forcenails make little wound and large joined controlling area. They are the ideal inner fixed objects.
