【摘要】 １９８９年１２月，我们参阅了ＧａｍｍａＬａｃｋｉｎｇＮａｉｌ的资料并改良制成交锁钉和手术器械，治疗股骨转子骨折３２例。术后６～１３天病人可离床活动，钉无折弯或断裂，未发生伤口感染或并发症。２９例随访５～１９个月，骨折全部愈合，髋关节恢复或基本恢复功能。２例髋内翻和１例患肢缩短２．５ｃｍ。我们认为该钉符合生物力学原理，适用于治疗各种类型的股骨转子骨折，骨折固定牢靠。更多还原

【Abstract】 AbstractWe improved and made the intramedullarv inter-locking nail and it’s instrument for surgical operationin December 1989 by consulting the reported materialof the gamma locking nail.32 cases of the femoraltrochanteric fracture were treated by using this fixationsystem. The results were satisfactory. The patientscould stand up and move about beginning from 6th to13th day after operation. No mechanical failure of im-plat,infection and other complications occurred in ourseries. 29 cases were followed-up for 5 to 19 monthsand showed all of the fractures were healed. Their hipfunct ions were completly or basically recovered.Coxavara deformity occurred in two cases and one had a2.5cm shortening of the lower limb.We consider thatthe intramedullary interlocking nail conforms to theprinciple of human biomechanics and it may be used asan effective surgical treatment with the fracture fixa-tion of superior strength and stability for every type offemoral trochanteric fractures.更多还原
