摘　　要：下胫腓联合的各条韧带具有不同的生物力学作用,在踝关节活动过程中下胫腓联合存在微动,并且下胫腓联合的损伤与踝关节体位和受力方式有关。关于下胫腓联合的最优固定仍存有争议,下胫腓联合的畸形复位会导致踝关节压力分布异常,弹性固定可能更符合下胫腓联合的生理活动。回顾下胫腓联合的生物力学研究进展,旨在为下胫腓联合损伤的合理治疗提供参考。Each of the syndesmotic ligaments has different biomechanical effects. Minimal movement occurs in the syndesmosis during the motion of the ankle joint,and the syndesmotic injury is associated with the ankle position and the patterns of external forces. Controversy still exists with respect to the optimal fixation of the syndesmosis. Malreduction of the syndesmosis would lead to abnormal pressure distribution on the ankle joint. Therefore,the flexible fixation might more accord with the physical movement of the syndesmosis. In this article,the biomechanical studies on syndesmosis are reviewed to provide the reference for proper treatment method for syndesmotic injury.
