摘　　要：肩袖撕裂是临床3大骨骼肌肉系统疾患之一,而冈上肌腱是最常见的病变部位。肩袖撕裂可引起慢性肩痛、力弱及关节活动受限,并导致肩关节的继发性退行性变。由于传统的生物力学实验受到测量技术和伦理问题的限制,肩袖的生理及病理状态下的应力分布几乎无法获取。近年来,随着计算机技术、软件开发和图像处理的不断发展,构建肩袖有限元模型的技术日臻成熟,已经为肩袖撕裂的发病机制及手术技术的研究提供了强有力的支持,成为肩袖生物力学研究不可缺少的工具。因此,在查阅近几年国内外相关文献后,本文仅就有限元分析在肩袖撕裂的发生及发展机制、肩袖修复手术中的应用进展作一综述,以资参考。Rotator cuff tears are one of the three most prevalent musculoskeletal disorders,with the supraspinatus tendon as the most common lesion site.It may lead to chronic shoulder pain,weakness and limited joint motion,and eventually to secondary degeneration of the shoulder.As traditional biomechanical experiments are limited by measurement techniques and ethical issues,it is almost impossible to clarify the stress distributions at the rotator cuff under physiological and pathological conditions.Recently,advances in computer science,software development and image processing have rapidly improved finite element models of shoulder joint which promote the researches into pathogenesis of rotator cuff tears and their surgical techniques,making finite element analysis an indispensable means in the biomechanic research of rotator cuff.This paper reviews the recent literature available in China and abroad to expound on the element models of shoulder joint applied in the researches into pathogenesis and surgery of rotator cuff tear.
