摘　　要：目的:探究谢式夹板外固定对Colles骨折(伸直型桡骨远端骨折)手臂的皮肤、骨骼及夹板等结构的生物力学特性影响。方法:对谢式夹板和解剖夹板外固定的手臂桡骨Colles骨折患者,采集两种夹板形式下的CT数据并进行影像重建,基于有限元方法建模仿真手臂皮肤及骨骼、夹板等结构的应力云图,并进行生物力学特性分析。结果:采用谢式夹板对手臂外固定后,在手臂皮肤表面不同区域出现明显的应力集中现象,同时由于受绷带压力、棉压垫、竹板、包裹纸板及侧向纸板的共同约束作用,导致谢式夹板本身结构应力分布也相对较显著。相比较而言,在桡骨骨折处手臂内侧、背侧对应的皮肤上谢式夹板的整体应力分布明显高于解剖夹板。结论:谢式夹板对手臂桡骨Colles骨折外固定后在桡骨骨折附近抵抗骨折错位移动有着较好的治疗作用。Objective:To study the biomechanical properties of Xie's splint external fixation on the skin,bone,splint and other structures of Colles'fractured arm.Methods:Xie's splint and anatomical splint were used for the external fixation of Colles fracture of arm radius.CT data of the two groups in the form of splint were collected and image reconstruction was carried out.The stress nebulogram of arm skin,bone,splint and other structures were simulated based on finite element method,and biomechanical analysis and research were carried out.Results:When the arm was externally fixed with the Xie's splint,significant stress concentration appeared in different areas of the arm skin surface.The structural stress distribution of the splint itself was also relatively significant.In comparison,the overall stress distribution of Xie's splint on the skin on the medial and dorsal sides of the arm at the radial fracture was significantly greater than that of the anatomical splint.Conclusion:Xie's splint has a good therapeutic effect on resisting fracture dislocation movement near radial fractures after external fixation of Colles fractures of the arm.
