Patient Specific Talus Spacer

The Patient Specific Talus Spacer is an additively manufactured implant, made from cobalt chromium metal alloy, that is intended to match the anatomy of the patient’s talus. The implant is used in adult patients only who have avascular necrosis (AVN) of the ankle joint. It allows patients who have limited treatment options and are at high risk for fusion or amputation to regain motion and reduce pain until the time a fusion becomes necessary. Movement in the ankle joint can occur where the distal tibia and the Patient Specific Talus Spacer connect. According to clinical data, the rate of reoperation was low, with 9.4% of cases (total of 32 cases, 31 patients) resulting in reoperation or correction.
