Abstract: | Background:The fingertip is the most frequently injured and amputated segment of the hand. There are controversies about defining clear indications for microsurgical replantation. Many classification systems have been proposed to solve this problem. No previous study has simultaneously correlated different classification systems with replant survival rate. The aim of the study is to compare the outcomes of fingertip replantations according to Tamai and Yamano classifications.Results:Of the 34 fingertips, 26 (76.4%) survived. Ten (66.6%) of 15 digits replanted in Tamai zone 1 and 16 (84.2%) of 19 digits replanted in Tamai zone 2 survived. There were no replantation failures in Yamano type 1 injuries (100%) and only two failed in Yamano type 2 (75%). Replantation was successful in 14 of 20 Yamano type 3 injuries, but six failed (70%). The percentage of success rates was the least in the hybridized groups of Tamai zone 1-Yamano type 2 and Tamai zone 1-Yamano type 3. Although clinically distinct, the survival rates between the groups were not statistically significantly different.Conclusions:The level and mechanism of injury play a decisive role in the success of fingertip replantation. Success rate increases in proximal fingertip amputations without crush injury. |
