Management of Talar Avascular Necrosis with Total Talus.

Avascular necrosis (AVN) of the talus is a difficult pathology to treat. Patient-specific factors such as functional status, comorbidities should be considered. Previous standard care for talar AVN was centered around arthrodesis procedures and loss of motion about the joints of the rearfoot and ankle. With the advent of 3D printed talar implants, patients are afforded an option to maintain ankle joint motion. Literature is limited due to the recent development of total talus replacement (TTR) technology. This article aims to review literature, surgical techniques, and pearls to better help foot and ankle surgeons treat cases of talar AVN.
