Hyperextension injury involving the PIP of the finger can avulse the volar plate which is commonly associated with a volar avulsion fracture at the base of the middle phalanx.
When the volar avulsion fracture involves a significant portion of the articular surface, instability and dorsal dislocation of the middle phalanx can occur.
