Irreducible proximal interphalangeal dislocation of the fourth toe: a case report

Dislocation of the interphalangeal joints of the lesser toes is an uncommon injury, and complex (irreducible) dislocation has rarely been reported. All previous reports note that, during open reduction, the volar plate is interposed within the joint, thereby blocking reduction. In this case, the medial collateral ligament was the primary obstruction to reduction. Clinically, these dislocations are difficult to appreciate. It is recommended that x-ray studies be performed so that this diagnosis is not overlooked.
