Lumbar disc prosthesis
activL® is the lumbar disc prosthesis for the motion preserving treatment of degenerative disc disease of the lumbar spine. The main objectives of the treatmentare fast pain reduction and the preservation/restoration of segmental function and motion. The specific design of activL® allows the protection of the adjacent level. The unique translational movement of activL® is designed to minimize biomechanical stress at the facet joints and to avoid facet joint arthrosis in a medium- and long-term prospect.
Advantages
- Unique translational movement to avoid biomechanical stress at the facet joint
- Unique translational movement for an effective protection of the adjacent disc levels
- Anterior and antero-lateral approach possible
- Specific instrumentation for the antero-lateral approach
- Design of prosthesis plates adapted to the anatomy of vertebral body endplates
- Unique PE-Material (Inlay) to reduce wear rate to 12-17% of other lumbar prosthesis types
- Specific prosthesis design treatment of L5-S1
- Plasmapore® coating for a fast and safe bony integration of the prosthesis plates to the vertebral body endplates
- Spikes and/or Keels as primary stability structures. Can be used together in any combination.
