摘　　要：目的:比较四种肌腱转移固定修复扁平足畸形的牢固程度。方法:本实验采用6具新鲜尸体骨标本,每一具标本依次采用腓骨长肌腱法、胫前肌腱法1、胫前肌腱法2及异体跟腱法4种转移肌腱固定方法修复扁平足模型。每一种标本模型分别固定在试验机上,轴向压缩100、300及600N,观察足底下移距离。结果:在100、300及600N力作用下轴向压缩,4种方法中足底下移距离比较,用腓骨长肌腱修复扁平足后产生的位移最小,与其他方法相比差异有显著性意义(P<0.05),其余三种方法之间差异无显著性意义。结论:本实验所研究的4种修复扁平足的方法中,腓骨长肌腱法修复扁平足最牢固。Objective：To explore the best method to treat flatfoot deformity with muscle tendon reconstruction. Methods：Six fresh-frozen adult cadaveric specimens were used to produce flatfoot models. Four tendon reconstruction methods, including long peroneal muscle tendon method, anterior tibial muscle tendon method 1, anterior tibial muscle tendon method 2, and heterogenous muscle tendon method,were applied to each models in the study. Each model was placed in an CSS -44020 materials-testing machine. The plantar downward displacement was tested under axial pressure of 100,300, and 600 N. Results： The pressure-migrating curve showed that when the pressure was 100,300 and 600 N, a small plantar downward displacement was produced by long peroneal muscle tendon method as compared with other three aforementioned methods（ P 〈 0.05 ）. There was no significant difference in the displacement among other three methods. Conclusion：Among the four methods of reconstruction,the long oeroneal muscle tendon method can obtain the strongest fixation.
