There are five stages of Distraction
The surgery in which the bone is cut and the distractor device is fixed
Osteotomy- Bone cut and distractor device
The time between the surgery and start of active distraction process
Latency Period- before activation of distractor
The period during which the distractor device is turned at a rate of 1 mm per day till the desired length is reached. The cut bone segments move apart.
Distraction period- distractor pushing the cut bone segments apart creating new bone in between
Activation of the distractor is stopped and the bone formed in the gap is allowed to mature. The distractor device is removed at the end of this phase.
Consolidation period- active distraction is stopped and bone is allowed to mature -comparison of CT scans before and after treatment
Remodeling of bone occurs after the distractor device is removed
