Oncologic reconstructive surgery of the talus with structural allograft: Case report

Abstract

Introduction and importance: Introduction and importance: Bone tumors of the foot constitute 3 % of all bone tumors, within these, the location in the talus constitutes between 8 and 23 % of bone tumors. Within the oncological management of these lesions, preservation surgery has had a great boom in the last 10 years, however, the use of massive structural allograft is not a conventional surgery and there is little literature on its use, which is why we consider important to document clinical cases. Case presentation: we document 2 clinical cases of bone tumor in the talus that were surgically managed with tumor resection plus reconstruction with total and partial talus allograft. Clinical discussion: Bone tumors involving the talus are rare and management techniques have emphasized intralesional resection plus bone graft application. In the literature consulted, no report of reconstructive surgery was found with the use of total and partial structural talus allograft. Conclusions: The use of structural talar allografts, both partial and total, has shown good functional results in short-term follow-up (18 months), so we consider it important to continue long-term follow-up to evaluate the evolution of this surgical technique.
