title: Irreducible dorsal subluxation of the first metatarsophalangeal joint: a case report.
abstract: We report a case of dorsal subluxation of the first metatarsophalangeal joint without dislocation of the sesamoids or destruction of the sesamoid complex. Closed reduction was unsuccessful. At surgery, the subluxation was found to be associated with locking of the abductor hallucis tendon onto the medial condyle of the metatarsal. After restoration of the tendon to its normal anatomic alignment, the joint was successfully reduced. One year after the injury, the patient was asymptomatic and had full range of motion of the metatarsophalangeal joint.
