RESUMO
Pain, premature degenerative arthritis, stiffness and persisting subluxation are common sequalae of fracture dislocations of the proximal interphalangeal joints of the fingers. With disruption of greater than 40% of the volar articular surface of the middle phalanx, it is un- likely that congrous stable reduction can be achieved. And the most severe injuries are caused by longitudinal compression force, which drives the middle phalanx where the middle phalanx eventually comes to rest. Many authors had reported a variety of method for the treatment of the unstable fracture dislocation with no satisfactory results except Eaton(1980). In his ten years experience the volar plate arthroplasty for acute and chronic fracture dislocations got a good results with satisfactory range of motion and no pain on motion. Authors had been treated two cases of chronic fracture dislocations of the proximal interphalangeal joint with Eatons volar plate arthroplasty followed by good results in one year followed-up study.
