摘要：

背景：随着体育竞赛对抗性和竞争激烈性的提高，运动参与者受内外部暴力影响的因素越来越多。而形状记忆合金作为一种新型的骨科内固定材料在临床治疗方面取得了良好效果。
目的：介绍形状记忆合金的治疗机制，并对骨折相关疗效进行阐述。
方法：由第一作者用计算机检索中国期刊全文数据库(CNKI：1980/2011)和pubMed (1980/2011)数据库，检索词分别为“记忆合金，骨，内固定，治疗”和“memory alloy，bone，internal fixation，treatment”，从形状记忆合金对骨折治疗的机制和疗效进行了阐述和总结。
结果与结论：共检索到138篇，按纳入和排除标准对文献进行筛选，共纳入29篇文章。综述了形状记忆合金的治疗机制，包括材料学特征、不同器材的工作原理与临床应用情况、骨折不同部位临床治疗措施与效果等方面的研究内容。结果提示，形状记忆合金具有诸多骨内固定材料的优点，是一种新型且良好的材料，但也存在一定的手术风险。而根据骨折部位的解剖形态学特征和特殊功能的要求，参照内固定材料的形状、大小及金属特性，妥善选择针对性强的内固定材料对治疗效果尤为重要。

Abstract:

BACKGROUND: With the elevation of opposability and intensity of athletic competition, participants were affected by varied internal and external violence. Shape memory alloy, as a novel internal fixation material in the department of orthopedics, has obtained good outcomes in clinical therapy.
OBJECTIVE: To introduce therapeutic mechanisms of shape memory alloy, and to analyze the fracture-related outcomes.
METHODS: The author retrieved China National Knowledge Infrastructure from 1980 to 2011 and PubMed from 1980 to 2011. The key words were “memory alloy, bone, internal fixation, treatment”. The mechanism and outcomes of shape memory alloy on fracture were summarized.
RESULTS AND CONCLUSION: A total of 138 articles were retrieved, and 29 articles were included in accordance with inclusion criteria and exclusion criteria. The therapeutic mechanisms of shape memory alloy were summarized, including material feature, working principle and clinical application of different instruments, clinical therapeutic measures and outcomes of fracture at different sites. Results indicated that shape memory alloy has many advantages of bone internal fixation materials, is a novel perfect material, but still has a certain operation risk. It is important to choose specialized internal fixation material for therapeutic outcomes in accordance with the anatomic morphological features of fracture site, requirement of special functions, shape, size and metal property of internal fixation material.
