WARNING
Danger of insufficient bone segment mobilization!
Insufficient mobilization will result in higher forces acting upon the distraction system. This
can lead to deformation or fracture of the distraction system. Therefore, please note:
The bone segments to be distracted must be mobilized before starting the distraction
•
process (corticotomy or complete osteotomy). To verify sufficient mobilization, an
activation test must be performed intraoperatively on the implanted distraction system.
The test activation must cover at least 1 – 3 mm and a continuous osteotomy gap must
be produced in the process.
Never allow the distraction system to get deformed during the distraction process!

Prior to Distraction (Latency Phase)
Once the distraction system has been implanted, a latency period must be observed before
starting the distraction process. The length of the latency period depends on the indication and
must be determined by the surgeon. It usually covers approx. 5 – 7 days (depending on
patient).
