BDyn
Posterior dynamic stabilization system
The BDyn device is intended to restore stabilization of the spinal segment from the T10 thoracic vertebra to the S1 sacrum while maintaining anatomical lordosis and intervertebral joint damping. It consists of a BDyn spinal damper fixed to the vertebrae using pedicle screws.
Clinical benefits
- Preserves mobility
- Delays segment fusion
- Stress damping
- Small footprint (11.5 mm)
- Versatility
- Dynamic assembly
- Topping-off
- Freedom of choice pre-operatively and intra-operatively:
- Non-fusion
- Fusion
- Elastomer damping
- 14° polyaxial flexible upper rod
- 10° angled lower rod to respect lordosis
- Maintenance of segment mobility:
- Flexion
- Extension
- Lateral bending
- Axial rotation
- Axial compression
Indications
The BDyn device is intended for posterior stabilization from the thoracic vertebra
T10 to the sacrum S1, with or without bone graft, for the following indications:
- Degeneration of the intervertebral disc and/or facet joints confirmed by additional examinations
- Lumbar spinal canal stenosis
- Grade 1 degenerative spondylolisthesis
- Segmental hypermobility
