Extensive Osteochondroma of Talus Presenting as Tarsal Tunnel Syndrome: Report of a case and Literature Review

Document Type : CASE REPORT


Department of Orthopaedics, Pondicherry Institute of Medical Sciences, Pondicherry, India


Osteochondroma or exostosis is the most common benign bone tumor, and occurring frequently in the proximal humerus, tibia, and distal femur. It rarely affects talus. Osteochondroma of talus is a very rare etiology of tarsal tunnel syndrome (TTS). We report a rare case of extensive osteochondroma of the talus in a 60 year old female presenting with multiple swellings around the ankle and symptoms suggestive of tarsal tunnel syndrome. En-block excision of the multiple masses was done. Histopathological examination confirmed the diagnosis of osteochondroma. Although most of the osteochondromas are being treated conservatively, those presenting with multiple swellings, restriction of movements and compressive neuropathies should be treated with surgical excision. Excision is a successful method of treatment for symptomatic osteochondromas with low recurrence.
