distraction osteogenesis
Surgical technique that gradually lengthens bone by creating controlled fractures and slow separation.
Full Definition
Distraction osteogenesis is a surgical procedure that stimulates new bone formation by gradually separating bone segments after a controlled osteotomy. The technique involves placing a distraction device that slowly pulls apart bone fragments, typically at a rate of 1mm per day, allowing new bone to form in the gap. This method is commonly used in craniofacial surgery for mandibular lengthening, midface advancement, and correction of various congenital deformities.
Usage
Usage note: Often abbreviated as 'DO' in surgical notes.
