Functional Testing and Lifespan of the
Spinal Kinetics M6-C Cervical Disc Replacement
Lifespan of the Spinal Kinetics M6-C Cervical disc replacement
The Spinal Kinetics M6-C is an cervical intervertebral disc replacement
designed to replicate the anatomic structure and biomechanical
performance of the natural disc. Its unique design allows for a
controlled range of motion in all 6 degrees of freedom. The
compressible viscoelastic polymer nucleus of the M6-C disc replacement is designed
to simulate the function of the native nucleus, while the surrounding
multi-layer high tensile strength Ultra-high-molecular-weight polyethylene fiber annulus provides
progressive resistance to motion and a physiologically restrained
construct.
Results
All testing indicated an extremely robust device that successfully
lasts the projected life of the implant. The functional kinematic
testing and physiologic dynamic testing demonstrated that the
M6-L passed all acceptance criteria. The assembly and all the
components remained fully intact and functional. The device
remained fully functional after 20 million cycles. The axial compressive
stiffness of the M6-C remained in the physiologic range throughout
and at completion of all cycles of testing. The results demonstrate
the durability of the M6-C: despite being subjected to highly
non-physiologic loading up to the limits of the test equipment,
no mechanical or functional failures were achieved.
The results of the creep testing and the worst case physiologic
sheath retention testing provide further verification of the
robustness of the M6-C.
Conclusion
The M6-C was subjected to rigorous testing which confirms the
inherent robustness of the device. The disc remains fully intact
and functional after functional kinematic testing to 20 Million cycles of
combined motion; physiologic dynamic compression, compression
shear, and torsion; creep to the equivalent of 100 years; and worst
case physiologic extension over 30,000 cycles. Even when highly
nonphysiologic static loads are applied, the device does not
exhibit any mechanical or functional failures.
The static and dynamic mechanical characterization of the M6-C
lumbar disc demonstrated that the device has the structural
integrity to last the life of the implant and that it exceeds the
necessary criteria for device safety over the life of the patient.
Dr. Ritter-Lang is now offering the breakthrough Spinal Kinetics M6 implant for the Cervical and Lumbar spine. The first disc replacement implant to truly deserve the title "Artificial Disc". This implant achieves the ultimate goal of replicating the healthy human disc. By providing shock absorption and graded variable motion resistance (to prevent facet arthrosis), the M6 works in concert with the remaining human discs, to provide the best possible outcome. This "Quality of Motion" is a major benefit not available in any other implant we have seen!
Are you confused about what treatment is the best option for you?
Maybe you have been told you are not a candidate for Disc Replacement. Many are told that fusion is their only option in error. Others are considering a temporary solution like discetomy, laminectomy or laser surgery.
