Distraction Osteogenesis
A surgical technique that lengthens bone by creating a controlled fracture and gradually separating the bone segments.
Full Definition
Distraction osteogenesis is a biological process of new bone formation that occurs when bone segments are gradually separated following a controlled osteotomy. The technique involves three phases: a latency period allowing initial healing, an activation period with gradual distraction, and a consolidation period for bone maturation. This method is particularly valuable in oral and maxillofacial surgery for correcting skeletal deficiencies and reconstructing bone defects.
Usage
Usage note: Often abbreviated as DO in clinical notes.
