Abstract

Although osteochondral lesions are well-described in previous literature, lesions located at the proximal phalangeal base of the hallux are extremely rare. Here, the authors report the case of a 21-year-old male who presented with chronic right great toe pain, which was eventually diagnosed as an osteochondral lesion at the proximal phalangeal base of the hallux. The diagnosis presented herein should be kept in mind and included in the differential diagnosis when patients complain of chronic pain in the great toe.
