Distraction Osteogenesis
Surgical technique that gradually lengthens bone by creating controlled separation at a fracture site or osteotomy.
Full Definition
Distraction Osteogenesis is a surgical procedure that stimulates new bone formation through the gradual mechanical separation of bone segments. The technique involves creating an osteotomy or utilizing an existing fracture, then applying an external fixation device that slowly distracts the bone segments at a controlled rate, typically 1mm per day. This gradual distraction stimulates new bone and soft tissue formation in the gap, allowing for limb lengthening or reconstruction of bone defects. The process consists of three phases: latency (initial healing), distraction (gradual lengthening), and consolidation (bone maturation). Documentation must include specific distraction rates, pin care protocols, and monitoring for complications such as pin tract infections or premature consolidation.
Usage
Usage note: Often associated with Ilizarov technique; specify distraction rate and method when documenting.
