Irreducible volar rotatory dislocation of the proximal interphalangeal joint.
Volar rotatory dislocation of the proximal interphalangeal (PIP) joint often cannot be reduced by closed manipulation because of interposition of soft tissues. In this case, the condyle of the proximal phalanx was trapped between the central slip and the lateral band. This case is reported to reemphasize the importance of recognizing serious injuries involving the soft tissues around the PIP joint. Deprival of its normal dorsal stabilizing forces can cause a loss of both static and dynamic joint support. Secondary scarring and contractures affect all damaged structures of the joint.
