title: Endoscopic Resection of Dorsal Boss of the Second and Third Tarsometatarsal Joints.
abstract: Dorsal boss of the foot also known as "tarsal boss," "dorsal exostosis," and "humped bone" is a bone spur that grows from one of the intertarsal or tarsometatarsal joints. It can occur with or without arthritis of the underlying joints. Surgery is indicated if the symptoms do not respond to conservative treatment. Excision of the dorsal boss with or without fusion of the underlying joint is the operative treatment of choice. We report an arthroscopic approach of resection of the dorsal exostosis. Arthroscopic arthrodesis if indicated can be performed through the same portals.
