摘　　要：本院研制的新型交锁加压髓内钉能广泛应用于股骨干稳定与不稳定骨折,且具有动力稳定性。本生物力学试验采用七具男新鲜湿润尸体股骨,使用新型交锁加压髓内钉固定,与国外GK钉比较,并与国内广泛采用的梅花钉比较。结果表明其极限承载能力、强度、刚度均高于GK钉与梅花钉。三者具有显著性差异(P<0.01)。新型交锁加压髓内钉经临床应用三十余例证明疗效显著,无生物应力遮挡作用,且具有安全,可靠,操作简单特点。The author designed a newtype compression intramedullary locking screw with dynamic stability, which is extensively used in the hospital for femoral fracture. This locking screw was mostly satisfactory by biomechanics test compared with GK and cloverleaf type intramedullary nail, for its greater bearing capacity, stronger and harder than the later two(P<0.01). The clinical results were shown better in thirty cases and the application of it is noted for its safety .reliability and simplicity.
