Subtalar joint brake is a prosthesis that is implanted into the tarsal sinus to limit the movement of subtalar joint. With the deepening of the understanding of subtalar joint brake, its clinical application has expanded from flexible flatfoot to subtalar joint dislocation and posterior tibial tendon dysfunction, and the operation mode has also expanded from single subtalar joint brake to subtalar joint stabilization. We reviewed the literature on subtalar joint brake. This article will review the new progress in subtalar joint brake classification, biomechanics, clinical application and complications.
