Abstract:
Objective To determine the factors influencing the survival rate and then quantifying the indication in digital replantation. Methods From January 1999 to November 2002,1 231 digit replantations were reviewed retrospectively.Analysis of Logistic regression was carried out between survival rate and injury degree of artery,skin,tendon,bone and nerve,mechanism of injury,severed levels,repassing duration and haemoglobin levels. Records of 50 failed and 50 succeeded fingers were selected at random and discriminant equation was made according to the factor selected by Logistic regression. Results The factors of injury degree of artery and skin,mechanism of injury,severed levedls and haemoglobin levels affected the survival rate significantly.The discriminant equation was that Z=6.42X 1+5.31X 1+4.35X 3+3.26X 4+3.15X 5. Conclusions The five factors mentioned above affect the survival rate of digital replantation.The indication of digital replantation could be quantified with the discriminant equation.
