Materials and Methods

35 consecutive tibial lengthenings were done for limb length discrepancy (LLD) in 26 patients. Gradual lengthening by an external fixator from a tibial (usually diaphyseal) osteotomy was followed by internal fixation with a lateral tibial submuscular plate. The mean age at the time of the lengthening was 10.3 years (4.8 – 16.8 years). The aetiology for LLD was congenital in 21, acquired in 3, and developmental in 2 patients. The mean follow-up was 4.3 years (8 months – 9.9 years).
