| 摘 要： | 目的:分析天鹅记忆加压接骨器(swan-likememoryconnector,SMC)固定肱骨时不同应力加载的选择,为今后肱骨骨折治疗时内固定器械的放置部位、载荷的施加方向及大小等提供力学依据。方法:选择湿肱骨标本行CT成像得到肱骨每层横截面图像,采用大型有限元分析软件ANSYS5.6建立肱骨、SMC以及SMC固定肱骨的三维模型。结果:所构建SMC固定肱骨三维模型,逼真反映真实解剖形态及生物力学行为,同时获得不同加载方式下肱骨的受力情况。结论:SMC固定肱骨三维有限元模型的构建,可以为肱骨正常力学行为以及骨折后内固定的力学基础研究提供精确模型。

| Abstract: | AIM:To analyze the selection of different stress to fixate the fracture humeru s with swan-like memory connector(SMC)and to find out its biomechanical signifi cance so as to provide a new method for continued research. METHOD:One wet humerus sample from corpse was scaned by CT and the image of ev ery layer of cross-section of humerus was obtained, and the humerus,SMC and fra cture humerus fixated with SMC model was constructed by means of ansys 5.6 softw are. RESULTS:The constructed three dimensional humerus, SMC model and fracture hume rus fixated with SMC model was clearly reflected the real humerus anatomy and bi omechanical behavior,then its truth was judged by contrast of humerus CT image. |

| Keywords: | The construction of humerus fixated with SMC three dimensional mode l can provide exacted humerus model for the research of normal mechanical behavi or or internal fixation mechanical basis after fracture. |
