Management of nonreducible lesser toe interphalangeal dislocation: an unusual injury.

Interphalangeal joint dislocations of the lesser toes are relatively rare in clinical practice. Most nonreducible interphalangeal joint dislocations occur as a result of rupture or interposition of the plantar plate or of the collateral ligament in the joint space, thus hindering a closed reduction and, in most cases, compelling an open reduction. A post-reduction radiologic exploration is then essential to identify such an entity and proceed consequently. In some cases, such as the one introduced herein, a misdiagnosis, along with an inadequate surgical correction may lead to recurrence of the deformity and, ultimately, to a salvage arthrodesis.
