Aneurysmal Bone Cyst of Talus: A Case Report

Segla Pascal Chigblo et al. J Orthop Case Rep. 2025 Sep.

Abstract

Introduction: Aneurysmal bone cyst (ABC) is a metaphyseal bone tumor that is frequent in children. Talar location is exceptional.

Case report: We report a case of this rare lesion managed in our department. It was a 16-year-old girl who presented with heel pain at walk, without any trauma. Radiologic explorations found a pathologic fracture of the right talus due to a bone cyst. A surgical procedure was proceeded, with curettage, and bone grafting completed by a plastered immobilization. Histopathology confirmed the diagnosis of ABC. Consolidation was achieved in 2 months, and there was no recurrence after 5 years.

Conclusion: ABC of the talus is a rare etiology of heel pain, which must not be forgotten in children.

Keywords: Aneurysmal bone cyst; bone grafting; curettage; pathological fracture; talus.
