FDA has approved Premia Spine’s TOPS System as an alternative to spinal fusion for treating certain patients with degenerative spondylolisthesis with moderate to severe lumbar spinal stenosis. The implant is designed to attach to the spine, and unlike a spinal fusion procedure, the TOPS System allows motion in the lower (lumbar) spine and may also reduce pain and help people return to normal activities, FDA says.

“In a posterior arthroplasty procedure, your surgeon removes the bony elements that press on your nerves,” the company says. “Thereafter, the doctor implants the TOPS System to stabilize and reestablish a controlled range of movement of the lumbar spine.”

The TOPS System is used at a single level between L2 through L5 — the segments most commonly affected by spinal stenosis. “It can also be combined with the Versalink Fusion System for multi-level disease between L1 and S1,” Premia says.
