Arthroscopic Ankle Arthrodesis

Video Transcription

This is a short video of an arthoscopically assisted ankle arthodesis. Fluid is coming trough the posterlateral portal, we’re viewing through the anteromedial, and a 6mm oval burr is coming in through the anterlateral portal, removing fibrocartilage and subchondral bone from the talus and also the tibial plafond. The burr needs to be maneuvered extremely carefully so as not to take too much tissue by way of subchondral bone from either the talus or the tibia. The burr is mobilized carefully over the convect surface of the talus, exposing bleeding subchondral bone. It’s important also, to properly clear the medial and lateral gutters to allow the talus to eventually snug up properly into the concave surface of the tibial plafond. It’s also important to remove the anterior tibial and dorsal talar spurs also to eventually allow good congruenty between the talar dome and the tibial plafond. One can see here that all subchondral bone has been exposed.
