摘　　要：目的:通过对不同治疗克雷氏骨折方法的比较,探讨桡骨长度丢失的原因及其动力来源。方法:将患者分为4组。A组采用常规复位,小夹板及纸压垫固定,麻醉消退后练习握拳。B组在A组的基础上前3周限制握拳。C组同A组治疗方法,只是将尺侧板加长使腕部置于轻度尺偏位以控制腕过度尺偏,练习握拳。D组在C组的治疗情况下前3周限制握拳。结果:4组患者从桡骨长度丢失、掌倾角丢失、尺偏角丢失、旋转功能受限及外观畸形各方面评价结果表明,D组效果最好,A组最差,C组优于B组(P<0.05)。结论:导致克雷氏骨折桡骨长度丢失的主要动力来源为屈指肌群及桡侧屈伸腕肌。Objective： To explore the reasons of the loss of radius length after Colles＇s fracture reduction through comparing the results of the different treatments. Methods： The patients were randomly divided into four groups. Routine closed reduction,splints and pads fixation and fisting exercise were performed after the anaesthesia vanished in group A. Fisting exercise was inhibited during the early 3 weeks in group B at the base treatment of group A. The different method in group C was to use the lengthened ulnar splint,which controlled the wrist at the low-grade ulnar inclination,and prevented excess ulnar inclination. The start exercise time of fisting was as same as group A. The treatment in group D was the same as that in group C, but fisting exercise was inhibited in the early 3 weeks. Results： The outcomes of 4 groups were evaluated for the lost of radius length, palm tilt angle, ulnar inclination angle, the rotation malfunction and malformation of the wrist. The outcome of group D was the best,and the outcome of group A was the worst. The outcome of group C was better than that of group B （P 〈 0.05）. Conclusion： The source of power which causes the lost of radius length is flexor digiterum,flexor and extensor carpi radialis.
