Limb lengthening is a surgical procedure designed to increase the length of the bones in the arms or legs. The procedure involves the use of external fixators or internal devices that gradually stretch the bone and surrounding tissues over time. Limb lengthening is commonly performed to correct limb discrepancies, treat conditions like achondroplasia (a form of dwarfism), or for cosmetic reasons. The process includes the initial surgery to place the lengthening device, followed by a period of gradual distraction where the device slowly lengthens the bone, and a final phase of consolidation to ensure proper bone healing and strength.
