Arthroscopic resection of navicular osteoid osteoma: A case report.

Abstract

This is the second navicular osteoid osteoma (OO) reported in the English literature and the first case of navicular OO treated by lateral arthroscopy of the sinus tarsi. The patient was a 32-year-old man who complained of chronic foot pain linked to an OO observed on computed tomography scan, magnetic resonance imaging, and scintigraphy. Endoscopic surgery was proposed after the failure of radiofrequency ablation, allowing total excision of the lesion. No complications were reported, and there was no residual pain at the 16-month follow-up. Most reported cases of OOs in the foot and ankle were located in the talar neck and distal tibia. The success rate of arthroscopic excision was 96%. Arthroscopic excision of OO by lateral approach represents a safe and effective alternative to radiofrequency ablation. V.
