锁骨骨折内固定有限元分析的研究进展

Research progress on finite element analysis of internal fixation for clavicular fracture

锁骨骨折为常见的上肢骨折,由于其特殊解剖结构直接影响着肩关节的功能。锁骨骨折不同的损伤机制影响着内固定的力学效果,因此选择何种内固定方式一直困扰着骨科医生。有限元分析作为现代计算机力学软件分析,通过对锁骨骨折内固定的有限元分析,不仅能够了解骨折病因机制、内固定物的生物力学性能及骨折并发症等因素,还能为术前规划上提供指导意见,有利于术前规划并进行手术方式的个体化选择,有望成为锁骨骨折术前规划中不可缺少的一部分。该文就有限元分析在锁骨骨折的病因机制、相关影响因素、内固定的选择、术后并发症以及有限元分析过程中出现的问题进行综述。

Clavicular fracture is a common upper-limb fracture.Because of its special anatomical structure,it directly affects the function of the shoulder joint.The different injury mechanisms of clavicular fracture affect the mechanical effect of internal fixation,so the selection of internal fixation method has been puzzling orthopedists.As a modern computer-based mechanical analysis,finite element analysis application in the internal fixation of clavicular fracture can not only clarify the pathogenesis of fractures,biomechanical properties of internal fixators and complications of fractures,but also provide guidance for preoperative planning.Therefore,it is beneficial to preoperative planning and individualized selection of surgical methods,and is expected to become an indispensable part in preoperative planning for clavicular fracture.In this paper,the pathogenesis,related influencing factors,selection of internal fixation and postoperative complications of clavicular fracture based on finite element analysis and problems during finite element analysis were reviewed.
