distraction osteogenesis
Surgical technique that gradually lengthens bone by applying controlled tension to stimulate new bone formation.
Full Definition
A surgical procedure that exploits the natural bone healing process to create new bone tissue through gradual, controlled separation of bone segments. The technique involves making a surgical cut in the bone, then slowly pulling the segments apart using an external or internal device. This creates tension that stimulates cellular proliferation and new bone formation in the gap, allowing for significant lengthening or reshaping of skeletal structures without bone grafting.
