The CHARITÉ™ Artificial Disc is comprised of proven orthopaedic materials; cobalt chromium Endplates and an Ultra-High Molecular Weight Polyethylene (UHMWPE) Sliding Core. Preclinical testing indicates that the unique mobile core design incorporates a floating center of rotation (FCOR), enabling independent translation & rotation, key components of physiologic motion. The mobile core moves dorsally during flexion and ventrally during extension.
The CHARITÉ Artificial Disc System includes an extensive range of core heights, endplate sizes and endplate angles providing the surgeon with numerous options to help ensure proper sizing, placement, and segmental lordosis.
The CENTRELINE™ TDR Instrumentation aids in midline placement for optimal performance.
- Preclinical testing indicates that this system is designed to:
- Maintain motion of the operative spinal segment.
- Maintain segmental stability.
- Restore proper disc height.
- Re-establish lordotic alignment.
About Lumbar Artificial Disc
Artificial disc replacement (ADR) is newer type of spinal disc procedure that utilizes an anterior (front – through the abdominal region) approach to replace a painful, arthritic, worn-out intervertebral disc of the lumbar spine with a metal and plastic prosthesis (artificial disc). Artificial disc replacement is primarily considered for patients with isolated 1-level (one disc only) degenerative disc disease. Prior to the development of ADR, spinal fusion was the principal treatment for painful degenerative disc disease that failed to improve with nonoperative management. ADR is generally NOT recommended for patients with spinal fractures, instability, neurologic compression, or multiple level degenerative disc disease – spinal fusion remains the treatment of choice for these conditions. The advantages of ADR include a faster recovery time than spinal fusion and preserved motion at the disc level. The theoretical long-term advantage of ADR, which remains unproven, is the possibility of decreased adjacent level stress and arthritis compared with spinal fusion.
