目的:探讨新型塑质克雷氏夹板在不同力学状态下的力学参数,为临床应用提供依据。

方法:取6套塑质夹板和6套柳木夹板,随机分为2组,每组再随机编号,分别进行横向及纵向弯曲测试,得出两个方向的弯曲最大载荷和对应位移,并进行对比,从而也计算出两种夹板的弹性模量。

结果:在横向弯曲方向塑质夹板明显大于柳木夹板(P<0.01);在纵向弯曲方向两者无显著性差异(P>0.05)。新型塑质夹板在不同受力状态下的弹性模量相同,而柳木夹板在不同受力状态下弹性模量不同,两者间有显著性差异(P<0.01)。

结论:新型塑质夹板力学性质稳定,是一种理想的外固定材料。

Mechanical test of a new plastic splint

Abstract:

Objective:To study the mechanical parameters of a new plastic splint in order to provide a theoritical basis for clinical application

Methods:6 series of new plastic splints and 6 series of willow splints were divided into 2 groups randomly;the load of bend of transverse and longitudinal orientation were applied to the splints separately.Also modulus of elasticity of two kinds of splints were calculated

Results:The new plastic splint in the load of transverse orientation was much greater than the willow splint(P<0.01),but there was no significance in the load of longitudinal(P>0.05).Modulus of elasticity of the new plastic is more stable than the willow splint in various mechanical conditions(P<0.01).

Conclusion:The character of the new plastic splint is stable and it is a perfect external fixation system.
