title: Irreducible open dorsal dislocation of the proximal interphalangeal joint: a case report.
abstract: We report a rare case of open dorsal dislocation of the proximal interphalangeal joint which needed operative reduction. A 39-year-old man injured his right middle finger while playing baseball. There was a laceration on the proximal interphalangeal crease, and the condyles of the proximal phalanx protruded through the wound. The flexor tendons had slipped behind the radial condyle, and made reduction impossible. After the flexor tendons and volar plate were replaced back into their normal position, the reduction was successful. Finally, the patient had full and painless motion of the digit. We review the reported cases of this injury in the relevant literature.
