The aim of this prospective clinical controlled trial was to investigate the early and midterm results of shaft fractures in children treated with elastic stable intramedullary nailing (ESIN).From January 1997 to December 2001, elastic stable intramedullary nailing was carried out on 112 children with 118 diaphyseal fractures. The mean age was 7.7 years. There were 51 fractures of the lower arm, 46 femoral fractures, 14 of the lower leg, and 7 of the humerus. A total of 92 children have been followed up for more than 12 months. The mean time of follow-up was 38months.The mean time of fluoroscopy was 2.2 min. Open reduction was necessary in 3.4 %. In children with injuries of the lower extremity, full weight bearing was achieved after a mean period of 9.3 days. In 1.8% of the children, reoperation was necessary within the first 10 days after the operation. In 3.6 % there was painful skin irritation due to the protruding end of a nail. No infection or delayed union was observed. Implant removal was done after a mean time of 5.6 months. There was no rotational or angular deformity of more than 5 degrees in children with isolated fractures of the lower extremity. Mean lengthening of the injured leg was 2.4 mm. In three children who had fractures of the upper extremity, a deficit in range of motion of the adjacent joints was detected.The current results show that intramedullary fixation of displaced diaphyseal fractures in children with a flexible titanium nail is a safe, minimally invasive surgical technique producing excellent functional and cosmetic results.
