AbstractThe rates of survival of the amputated part and the functional outcomes were studied retrospectively after seventy-three replantations and eighty-nine revascularizations in the upper extremity in 120 children. All operations were performed between January 1974 and December 1988 after partial and complete amputations at various levels. The ages of the patients ranged from three days to sixteen years. The average duration of follow-up was thirty-six months (range, fourteen months to seven years) for the patients who had had a replantation and thirty months (range, fourteen months to eight years) for the patients who had had a revascularization. The rate of survival of the amputated part was significantly higher (p < 0.0002) after revascularization (seventy-eight parts [88 per cent]) than after replantation (forty-six parts [63 per cent]). There was no association, for either group, between survival and the preoperative duration of ischemia, the level of the injury, the digit that had been injured, the number of arteries that had been repaired, or the use of venous grafts. The rate of survival after replantation of completely amputated parts was 72 per cent (twenty-eight of thirty-nine parts) when the amputation had resulted from a laceration injury and 53 per cent (eighteen of thirty-four parts) when the amputation had resulted from a crush or an avulsion injury. The rate of survival after revascularization of incompletely amputated parts was 100 per cent (all forty-five parts) when the injury had been the result of a laceration and 75 per cent (thirty-three of forty-four parts) when it had been the result of a crush or an avulsion. We did not find any relationship between the age of the patient and the rate of survival of the amputated part after revascularization; however, there was a significantly higher rate of survival (p , 0.02) after replantation in children who were less than nine years old (77 per cent [twenty-four of thirty-one parts]) compared with the rate in those who were nine to sixteen years old (52 per cent [twenty-two of forty-two parts]). The viability of the digit was in jeopardy after twenty-nine (40 per cent) of the seventy-three replantations and nineteen (21 per cent) of the eighty-nine revascularizations. Immediate reoperation resulted in the salvage of only two of the twenty-one replanted parts and six of the twelve revascularized parts that had a reoperation.(ABSTRACT TRUNCATED AT 400 WORDS)
