title: A unique osteochondral fracture of the first metatarsophalangeal joint.
abstract: Presented is a case report of an osteochondral fracture occurring at the base of the proximal phalanx of the hallux secondary to trauma. Initial radiographic and clinical examination did not reveal the diagnosis. However, prolonged symptoms of pain, swelling, and limitation of first metatarsophalangeal joint range of motion led to further radiographic evaluation, which confirmed a suspected diagnosis of an osteochondral fracture. This is regarded as a most interesting case by the authors, in light of the fact that review of the literature revealed a paucity of descriptions of osteochondral fracture of the first metatarsophalangeal joint. In addition, all of the previously described lesions have been localized to the first metatarsal head. A review of the literature failed to reveal any fractures occurring at the base of the proximal phalanx of the hallux.
