Modified Blair Tibiotalar Arthrodesis for Post-traumatic Avascular Necrosis of the Talus: A Case Report

摘要

Surgical treatment of post-traumatic avascular necrosis of the talus coupled with collapse often results in limited treatment options. Of those options, the Blair tibiotalar arthrodesis has been beneficial in preserving limb length and subtalar motion. The complications associated with Blair tibiotalar arthrodesis have led to modifications to improve stability and functional outcomes with rigid internal fixation. We present the case of a 29-year-old female with a history of an open fracture dislocation of the talus 10years previously, with subsequent development of avascular necrosis of the talus. The purpose of the present case report was to describe the surgical approach and use of an anterior compression plate to augment the modified Blair tibiotalar arthrodesis.
