Palmar fracture dislocation of the PIP joint is very unusual. We reported one case who sustained this injury. The patient was a 35-year-old man. He sustained a palmar fracture dislocation of the PIP joint of the left long finger on a frontal clash of a car. The dorsal aspect of the middle phalanx seemed to be hit by a dashboard. X-ray photograph showed palmar dislocation of the middle phalanx with displaced dorsal base fracture fragment and depressed fracture of the articular surface. Open reduction and internal fixation with three Kirschner wires were performed at four days following the injury. Immobilization was continued for four weeks. The patient complained of no pain and acquired almost full ROM of the PIP joint at six months after surgery. This injury might occur when a great force was applied to the dorsal aspect of the middle phalangeal base on flexed PIP position.
