[Proximal interphalangeal joint dorsal dislocations without fractures--four cases report].

Four patients with proximal interphalangeal joint (PIP) dorsal dislocation without fracture had been treated at Chang Gung Memorial Branch (Kaohsiung and Keelung) Hospital from June 1987 to Jan. 1989. All four cases were open dislocations, only one patient received immediate diagnosis and treatment, while the other 3 cases were delayed diagnosis and treatment. Open reduction, repair of the ruptured ligaments and joint capsule, reinsertion of the disrupted volar plate were given in these 4 patients. The patient with immediate surgical treatment received rehabilitation program, the other three patients with delay surgical management did not receive rehabilitation program. The rehabilitation program included early active exercises of the PIP joint, started from the second week postoperatively. The rehabilitation period was about three to six months. The prompt diagnosis, reduction, institution of appropriate treatment and rehabilitation might result in better function of the PIP joint after dorsal dislocation.
