ANATOMIC STRUCTURES AT RISK - COMBINED SUBTALAR AND ANKLE ARTHRODESISWITH A RETROGRADE INTRAMEDULLARY ROD

Retrograde intramedullary redding from the calcaneus, through the talu s, and into the tibia is currently an evolving procedure being used fo r salvage of severe foot/ankle deformity, arthritis, tumor, and instab ility. In this study, retrograde redding was performed on six cadaver specimens. The specimens were then dissected to determine the subcalca neal structures at risk and the optimal insertion point for the rod. T his study elucidated the structures most at risk and showed the optima l insertion site to be at the junction of the sustentaculum tall and t he body of the calcaneus.
