摘要

目的:探讨双重空心加压螺钉（Ideal compression screwI

.CO.S.）在治疗股骨颈骨折中的生物力学作用

并为临床上选择合适空间构型的2枚此类螺钉治疗股骨颈骨折提供一定的理论依据。方法:采集20具尸体股骨标本

模拟股骨颈头下型骨折

随机分为I.CO.S.组（实验组）和普通空心加压螺钉组（对照组）

每组各10个标本

分别随机采用2枚水平位（2枚螺钉前后平行位于股骨颈轴心上方）和垂直位（2枚螺钉上下平行位于股骨颈轴心上下方）固定各5个。测定各组载荷下的应变值、股骨头的水平和垂直位移、并进行屈服力学性能测试。结果:在生物力学稳定性方面I

.CO.S.在水平位移和屈服载荷方面较普通空心加压螺钉好

螺钉水平位固定在应变、水平位移和屈服载荷方面较垂直位好。结论I:.CO.S.固定股骨颈骨折的稳定性较好

且2枚I.CO.S.水平位固定有较高的稳定性可应用于临床。

Abstract

Objective:To explore the biomechanical stability for treatment of femoral neck fracture with ideal compression screw(I.CO.S.)and to provide theoretical basis for choosing appropriate geometric configurations of two I.CO.S.s in clinical application.Methods:20 cadaveric human femurs were selected and divided randomly into two groups:experiment group and control group

10 in each one which was then divided equally into two sub-groups.The model of subcapital femoral neck fracture was made

then given anatomical reduction and fixed with I.CO.S.(experiment group)and general cannulated compression screw(control group)separately with two different configurations:horizontal one(parallel screws in superior as pect of femoral neck)and vertical one(parallel screws in sagittal plane of femoral neck).The different biomechanical performances were evaluated through experimental stress analysis.Results:In biomechanical stability aspect

I.CO.S.was better than general screw in the horizontal displacement and yield load;the horizontal one was better than the vertical one in respect of the straining

horizontal displacement and yield load.Conclusion:There exists good biomechanical stability for treatment of femoral neck fracture with I.CO.S.

and the horizontal I.CO.S.internal fixation with higher stability can be used for treatment of femoral neck fracture.
