Category:HindfootIntroduction/Purpose:Many patients with talar avascular necrosis have limited treatment options to manage their symptoms. Historically, surgical options have included pan-talar fusions, tibio-talar-calcaneal fusions, and revascularization procedures. Unfortunately, these treatment options can leave patients with little ankle and hind-foot motion, can increase adjacent joint arthritis, and have significant failure rates. Recently, the use of custom 3D printed total talar replacements has arisen as a treatment option for these patients. Theoretically, this allows for better preservation of hind-foot motion as well as possibly less adjacent joint arthritis.Methods:We retrospectively reviewed 15 patients who underwent a 3D printed total talus replacement by a single surgeon over 2 years. Each patient had pre-operative CT scans of both the affected and non-affected talus. Custom 3D printed implants were made in two sizes based on templating performed on the contralateral talus. All total talus...
