distraction osteogenesis
A surgical technique that gradually separates bone segments to stimulate new bone formation, commonly used for limb lengthening.
Full Definition
Distraction osteogenesis is a biological process and surgical technique that generates new bone tissue by gradually separating bone segments after an osteotomy. The process follows three distinct phases: latency (initial healing period), distraction (gradual separation at approximately 1mm per day), and consolidation (maturation of new bone). This technique exploits the bone's natural healing capacity and is commonly used for limb lengthening, treating bone defects, and correcting deformities. The gradual distraction also allows simultaneous lengthening of muscles, vessels, and nerves, minimizing complications compared to acute corrections.
Usage
Usage note: Often abbreviated as 'DO' in clinical notes.
