摘　　要：外固定主要分为单边、环形和混合外固定三种。随着医疗技术的发展,更多的外固定结构出现,但大多是以上3种外固定结构的衍生结构。医工联合日渐紧密,不断有针对外固定材料、结构力学等的研究出现。目前,通过改变外固定材料及结构仍可使临床效果得到优化。无论外固定结构如何,均需要从生物力学角度对其稳定性进行分析,而如何最大化外固定结构的稳定性同时保证足够的微动以产生断端必需的生物力学刺激,至今仍未得出一致结论。随着科学技术的发展,通过与计算机辅助技术结合,高精度的自主复位外固定系统或辅助复位工具将应用于临床。External fixation can be divided into three types:unilateral,ring and mixed external fixation.With the development of medical technology,more external fixation structures are designed,most of which are derived from the above three types.The medical and industrial union is getting closer and closer,and research on external fixation materials and structural mechanics has been seen.Nowadays,the clinical effect can be optimized further by changing external fixation materials and structures.No matter what the external fixation structure is,its stability should all be analyzed from the perspective of biomechanics.However,so far no consensus has been reached on how to maximize the stability of the external fixation structure while ensuring sufficient movement to generate the biomechanical stimulation necessary for the broken ends.With the development of science and technology,by the combination of computer assisted technology,a high-precision autonomous external fixation system for reduction or auxiliary reduction tools will be eventually applied in the clinical practice.
