Salvage procedures for calcaneus fractures

Salvage procedures reverse the anatomic factors that cause widening and mechanical misalignment of the hindfoot. Posttraumatic arthrosis of the subtalar joint is treated by arthrodesis, using techniques that improve alignment. The easily measured goal is to restore the normal plantar alignment of the talus (Meary's line) and return the calcaneal tuberosity to the weightbearing line beneath the talus. The subtalar joint is the joint most often treated by arthrodesis, although a triple arthrodesis is sometimes required when Chopart's joint is involved.
