Bone lengthening is a surgical procedure indicated to correct differences in limb length, whether congenital (dwarfism) or acquired (following trauma). This procedure helps to harmonize the figure and improve the function of the affected limbs. It can be performed on the upper or lower limbs, bilaterally or unilaterally.
Lengthening techniques are varied, using devices such as external or internal fixators and intramedullary nails. These devices create a microfracture in the bone (osteotomy),which is gradually expanded at a rate of about 1 mm per day, stimulating the formation of new bone tissue.
