BDyn is a posterior dynamic motion preservation system
which is designed for application from thoracic vertebrae T10 to sacrum S1.
The dynamic rod BDyn is composed of a silicone cushion, that helps to decrease intradiscal pressure
and to relieve facet loads
, and an elastomere ring that controls hyper mobility and limits extention of the spine segment
BDyn enables all anatomical motion such as flexion/extension, axial rotation as well as lateral bending.
Beside a one level motion preservation device, BDyn has also a version with a longer fusion rod to combine 1 or 2 levels of fusion with motion preservation for the adjacent segment.
BDyn is indicated for lombar surgery in case of :
- Degenerative intervertebral disc disease
- Spinal canal stenosis
- Degenerative spondylolisthesis grade 1
- Segmental instability
