Lumbar disc prosthesis activ® L

activL® 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. Features - Unique translational movement - Convex prosthesis plates - Anatomical adapted footprint - Differentiated implant design for L5-S1 - Spikes and/or Keel - Plamapore® coating - Specific PE material for the Inlay - Smallest height with 8.5 mm - Instrumentation for the lateral approach - Free choice of direction of approach (angulation) - Revision instruments
