Spinal Kinetics M6 Lumbar Disc Replacement
Top Spine Surgeon Dr. Ritter-Lang finds the elasto-metric properties of the ESP Disc Replacement to be a bit stiff.
Dr. Ritter-Lang "the visco-elastic properties of the Spinal Kinetics M6 are more consistent with restoring natural motion."
The Spinal Kinetics M6 Lumbar Disc Replacement offers a "Quality of Motion" that is not present in any other implant we have seen!
Unlike early Disc Replacement designs, the Spinal Kinetics M6 lumbar artificial disc is designed to replicate the structure and performance of a natural disc. Its innovative design incorporates an artificial nucleus to allow shock absorption and a woven fiber annulus for graded variable motion resistance in all directions.
These characteristics accurately replicate the natural disc, allowing the implant to work in concert with the remaining human discs. Unlike earlier "ball-in-socket" implants, with the M6 disc replacement the resulting natural functionality of the entire spinal curve will provide the best chance for a full recovery. In addition, future complications will be eliminated by reducing adjacent level degeneration and strain on the muscles and ligaments.
This "Quality of Motion" is a major patient benefit not available in any other implant!
The Spinal Kinetics M6 Lumbar artificial disc replacement offers an innovative option compared to other artificial lumbar disc replacement because of its unique design, which is based on the qualities of the natural disc.
The M6 Lumbar Disc Replacement is the only artificial disc that incorporates an artificial nucleus (made from polycarbonate urethane) and a woven fiber annulus (made from polyethylene). The M6-L artificial nucleus and annulus are designed to provide the same physiologic motion characteristics of a natural disc. Extensive biomechanical testing with the M6-L artificial lumbar disc has demonstrated equivalent Quality of Motion compared to the healthy disc.
Together, the M6 Lumbar’s artificial nucleus and annulus provide compressive capabilities and a controlled range of natural motion in all 6 degrees of freedom. This “natural” motion is designed to provide the freedom to move your back naturally.
The M6 Lumbar Disc Replacement has two titanium outer plates with keels for anchoring the disc into the bone of the vertebral body. These outer plates are coated with a titanium plasma spray that promotes bone growth into the metal plates, providing long-term fixation and stability of the disc in the bone.
