Medial fracture dislocation of hallucal interphalangeal joint. A case report.

A case of medical fracture dislocation of the hallucal interphalangeal joint is presented. The patient did not recall the specific mechanism that caused this injury. However, this type of injury would have to entail a substantial lateral-to-medial force at the distal phalanx. The authors' review of the literature did not reveal a similar case involving a medial dislocation of the distal phalanx. This transverse plane pathology was treated with closed reduction because of a lack of sesamoid or volar plant involvement in the joint.
