Methods of limb elongation with congenital inequality in children

During the period 1973-1978 elongation with a distraction-compression apparatus was performed on 78 children with congenital limb length inequality. The length of follow-up ranged from 2 to 6 years. Inequality in limb length measured 4 to 6.5 cm in 51 children, 6.5 to 8 cm in 24, and more than 8 cm in three. The final results in 72 children were judged satisfactory in that equal limb length was obtained. Equalization was accomplished with lengthening up to 6 cm in a one-stage procedure; lengthening greater than 6 cm was accomplished in two stages. During distraction two fractures and six pin tract infections occurred; four patients with joint stiffness adjacent to the segment under elongation required additional measures.
