[Bone growth after finger replantation in childhood].

Following replantation in childhood, growth disorders of the affected epiphysis can influence function and aesthetic appearance of the hand. In a retrospective study long-term results of replantation in the upper limb in childhood were analysed with respect to factors influencing further growth. 22 patients with 29 replanted fingers were reviewed clinically and radiologically after an average interval of ten years. An average bone growth of 93% compared to the contralateral non-injured side was found. With the epiphysis affected, bone growth was reduced to 86% of the contralateral side. Analysis of single phalanges showed a growth rate of 71 to 100% in phalanges distal to the amputation and also in phalanges initially severed. Potential factors influencing bone growth were assessed separately. Best results were achieved in straight injuries without epiphyseal affection. An influence of anoxia time or number of anastomosed vessels could not be found. Even though replantation in childhood affects growing bone, almost normal bone growth can be expected afterwards.
