Answer

Posterior PIP fracture-dislocations occur with volar lip fractures and volar dislocations with dorsal avulsion fractures. Posterior fracture-dislocations usually involve some degree of axial compression, comminution, and involvement of the volar articular surface. Treatment methods are grouped into the following 5 categories: static immobilization, dorsal extension block splinting, longitudinal traction, open reduction and internal fixation, and palmar plate arthroplasty.
