Bone growth after replantation in children.
Bone growth and the development of epiphyseal plates are disturbed after the replantation of amputated extremities in children, but the potential for continued skeletal growth is almost always maintained in the replanted part. In this reported series of 12 children, all younger than 15 years old, 13 amputated parts of the upper limb have been successfully replanted. After long-term follow-up (from 21 to 216 months), bone growth of the replanted parts was clinically and radiologically evaluated. Two different growing segments were distinguished: the proximal bone segment, directly injured from the initial trauma, and the distal replanted part. Average longitudinal growth recorded was 94.5 percent and 92.7 percent, respectively. Two young patients demonstrated overgrowth of the proximal bone segment, which attained 110 percent and 118 percent of expected growth. Although it is difficult to determine all the parameters affecting the prognosis of post-traumatic reactions in growing cartilaginous plates, the level of amputation is considered to be a significant prognostic factor for the epiphyseal growth of the replanted part.
