Abstract

Composite grafting remains a technique which is used reluctantly and without great hope of success. In the recent two years, unexpectedly good result of composite graft was gained from 30 cases. The purpose of our study is to identify factors influencing success and to overlook long-term problems from a cosmetic and a functional view point. A retrospective review and a questionnaire about 30 fingers of 29 patients which were operated for composite graft at Kyongju hospital of Dongguk university from March 1997 to February 1999 were carried out. In all cases of composite grafting, tie-over dressing and heat lamp were applied and left for five days. And following result and conclusion were obtained. 1. 24(80%) of 30 finger tips replaced as composite graft were survived completely or partially. 2. At children with an age range 1 to 14, the survival rate (100%) of composite grafted tips was higher than that (75%) at adults. So, patient's age was important factor for success. 3. The type of injury was more important factor than the level of amputation. The survival rate(100%) of tips to cutting injury was higher than that(75%) of tips to crushing injury. 4. The delay in time from amputation and replacement did not significantly correlate with the survival rate. But, all tips replaced within 3 hours were survived completely or partially. 5. Even if partial necrosis on grafted tips was present, a result of long-time conservative treatment with minimal debridrement was excellent. Especially in children, the tips with conservative treatment showed normal appearance, several months later. 6. Cosmetic and functional results were better in child group and in groups with higher survival rate. Most common problem in cosmetic aspect was a short digit and that in functional aspect was a tender tip. 7. As a heat lamp increased blood supply, we could obtain better outcome.
