Abstract

The subtalar joint can be altered in its anatomy and biomechanical behavior. It is important to know how to assess the talar declination angle in order to assess the deformity at the subtalar joint. Consider a straight posterior approach to the subtalar joint and remain liberal in the use of z-shaped Achilles tendon lengthening. A structural bone graft should be used to elevate the talus. Positioning screws should be used to lock the construct.

摘要

距下关节的解剖结构和生物力学行为可能会发生改变。了解如何评估距骨倾斜角度对于评估距下关节的畸形情况很重要。考虑采用直接的后路入路至距下关节，并在使用Z形跟腱延长术时保持灵活。应使用结构性骨移植来抬高距骨。应使用定位螺钉来锁定结构。
