32 patients (age range 1.5-22 years) were treated for leg-length discrepancy. 39 lengthening procedures were performed of which 36 involved gradual distraction, in 2 cases chondrodiasthesis was used, and 1 had 1-step elongation. Gradual distraction was done according to Ilizarov, including corticotomy and a 1-week delay before the initiation of distraction. In 33 cases Wagner's external fixator was used, in 2 Ilizarov frame and in 1 an orthofix fixator. There was complete clinical and radiologic union in all but 1 case. Significant correction of leg-length discrepancy and equalization of leg-length was achieved in most patients. In some growing patients over-correction was successfully achieved. The most prevalent complications were pin-site problems, axis deviation, joint subluxation and joint contractures. At latest follow-up most of these complications had disappeared. 91% of the patients either functioned normal or were only mildly limited.
