Subtalar Distraction Arthrodesis

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.
