DSS
Paradigm Dynamic Stabilization System
The DSS system is a pedicle-screw based, implantable dynamic spine stabilization system indicated for degenerative disc disease (DDD) of the lumbar spine. The DSSTM system incorporates a hybrid philosophy, combining elements of fusion and motion preservation.
The system was developed over a two-year period in close cooperation with Professor Hans- Joachim Wilke, a world-renowned Professor of Biomechanics from the University of Ulm in Germany, and Dr. Bertagnoli, the most experienced spine arthroplasty surgeon worldwide.
The modularity of the DSSTM system enables the combination of DSS dynamic couplers with DSS fusion couplers at adjacent levels. Therefore, one segment may have functionally dynamic stabilization (non-fusion) while an adjacent segment has rigid segmental fixation (fusion) under the same system.
The DSS dynamic coupler increases the stiffness of the affected motion segment and restricts the range of motion in flexion, extension, lateral bending and rotation while preserving motion. By selecting the appropriate size DSS dynamic coupler, the posterior segmental height can also be adjusted. The DSS fusion coupler provides rigid segmental fixation utilizing the same instrument set. One of the features and benefits of the system is the use of percutaneous screw positioning that facilitates a minimally invasive muscle-sparing approach.
The DSSTM system is one of the first truly dynamic stabilization systems because it increases segmental stiffness while controlling specific ranges of motion.
