Lumbar disc prosthesis M6-L

The M6-L artificial lumbar disc 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-L 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-L’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-L 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.
