Purpose  Management of finger amputations of the proximal interphalangeal (PIP) joint is still controversial. Regrettably, injured PIP joints seldom regain normal active motion; thus, many investigators recommend revision amputation with skeletal injury at or proximal to the PIP joint. We report the functional outcome of patients with replantation or revascularization following complete or incomplete amputations of the PIP joint.    Methods  A total of 15 digital replantations or revascularization were performed on 11 patients (9 males and 2 females, age, 26–69 years) with severe finger injuries at the PIP joint at our Medical Center from 2010 through 2012. Seven patients with 10 complete amputations underwent replantations, and 4 with 5 incomplete avulsion amputations underwent revascularization. PIP arthrodesis was performed in all cases. Routine postoperative evaluation was performed in 13 successfully treated patients.    Results  The 13 successfully treated cases were tracked over a follow-up of 12 to 55 months. Arthrodesis of PIP caused significantly lower total active range of motion (TAM; 85–120°). The mean DASH score was 37/100 (range: 10–64 points). Although mobility is poorer in PIP replantations, adequate PIP joint fixation improves DASH score and hand function.Conclusions   PIP replantation along with arthrodesis at a functional position for a finger amputation should be performed when the patient wishes to undergo replantation, which facilitates patient satisfaction.

Proximal interphalangeal replantation with arthrodesis facilitates favorable esthetics and functional outcome
