塑性弹力夹板治疗伸直型桡骨远端骨折疗效及生物力学定性分析

Biomechanics of plastic splint on the treatment of Colles fracture

[目的]探讨塑性弹力夹板治疗伸直型桡骨远端骨折的临床疗效,并对塑性弹力夹板进行生物力学原理定性分析。[方法]2002年9月～2008年8月选择105例桡骨远端伸直型骨折患者,骨折整复后应用塑性弹力夹板固定。观察周期结束后3个月按照Gartland、Werley评分系统对腕关节功能进行评价。[结果]治疗过程中,有2例患者行塑性弹力夹板固定后失去联系,以依从性差给予脱落;合计完成病例103例,完成率为98%。观察周期结束后3个月随访进行腕关节功能评价:优80例,良13例,中7例,差3例,优良率达到90.3%。[结论]采用塑性弹力夹板对桡骨远端伸直型骨折进行中立位固定,临床疗效确切,而其有效性主要依赖于合理的生物力学设计。

[Objective]To evaluate the clinical effect of the plastic splint on treatment of Colles fracture.[Method]A total of 105 patients with Colles fracture were collected between September 2002 and August 2008.All patients were perfromed using the plastic splint afrer diaplasis.According to Gartland and Werley scoring syste,the function of wrist was evaluated after 3 months.[Result]There are only 2 cases losing during treatment,103 cases were finished.The average excellent to good case was 90.3%,including 80 cases of being excellent,13 of being good,7 of being fair and 3 of being poor.[Conclusion]The plastic splint is exactly effective to treatment Colles fracture,especially,it could effectively relieve swelling and improve the contour of the wrists.Theses all rely on reasonable biomechanics design.
