Irreducible longitudinal distraction-dislocation of the hallux interphalangeal joint.

Although volar and dorsal dislocations have been described in the literature, dislocation of the hallux interphalangeal joint is a disorder rarely encountered by orthopedic and foot surgeons. In this article, we report a case of a distinct irreducible longitudinal distraction-dislocation that originally presented to the emergency department but required open reduction in the operating room. We also describe the presentation, anatomy, and treatment of this unique disorder.
