Twelve achondroplastic dwarfs underwent serial limb lengthening during childhood. All had
repeated bilateral simultaneous elongation of their lower limbs. The height of these patients
was plotted on growth curves for children with achondroplasia. The end results were
evaluated after all patients reached skeletal maturity. Growth acceleration was seen in male
patients with achondroplasia, but no such effect was seen in females. The female patients
lost several centimeters as calculated from their predicted final height based on their …
