Todd Lanman, MD, and Jared Ament, MD, performed the first known case combining the Motus total joint replacement implant and the Tops system at adjacent levels.
The landmark case was performed on a man with severe facet disease, according to a May 20 news release. The Motus device was implanted at segments L5-S1, and the Tops system was implanted at segments L4-L5.
“This is the first time the Motus total joint replacement has been placed at the bottom level of the spine with a Tops device directly above it,” Dr. Lanman said in the release. “The biomechanical challenge was significant. L5-S1 is a high-load bearing level, and placing Motus beneath a Tops device at L4-5 required precise alignment, careful load distribution planning and complete mastery of both technologies. This patient’s severe facet disease made him an ideal candidate for this innovative construct, and we are thrilled with the early outcomes.”
Motus is a posterior total joint replacement device from 3Spine. Premia Spine’s Tops system is an alternative to spinal fusion.
