The prognosis of limb length discrepancy is a major subject in paediatric orthopaedic surgery. The strategy depends on the prognosis and must be adapted to each patient. The residual growth of the lengthened segment often remains unknown, but is dependent on age, the percentage of lengthening and other factors. Using a large cohort of 150 children who had undergone bone lengthening procedures, we describe five patterns of post-intervention growth and identify factors that are favourable for normal residual growth. The criteria for bone lengthening which should maintain good residual growth are-bone age at lengthening should be before the pubertal growth spurt; the interval between two lengthening procedures should be over three years; the percentage of lengthening should be <30% of the initial segment; and no more than two lengthening procedures should be carried out during infancy.
