Amplio Spine Acquires FloSpine’s KeyLift Expandable Interlaminar Stabilization

Amplio Spine has closed the asset acquisition of the KeyLift expandable interlaminar stabilization from FloSpine and began a national launch of the technology.

KeyLift is a posterior, non-pedicle, supplemental fixation device for use at a single level in the non-cervical spine (T1-S1). It’s meant for plate fixation and attachment to the spinous processes/lamina to achieve supplemental fusion in lumbar spinal stenosis, degenerative disc disease, spondylolisthesis, trauma, and/or tumor. The device is intended for use with allograft or autograft bone and not intended for standalone use.

The acquisition transferred the full IP portfolio, 510(k) clearance, finished inventory, and established distributor relationships. The transaction’s financial terms were not disclosed—Amplio Spine is privately held and founder-funded, operating without outside institutional capital.

Posterior spinal fixation has long been pedicle-based, and pedicle screw constructs are the standard of care for many indications. In a cadaveric study published in Global Spine Journal, authors measured bone mineral density, cortical volume, and cortical thickness across seven anatomical regions of the lumbar vertebrae and reported the lamina (along with the inferior articular process) showed significantly greater cortical thickness and bone mineral density than the pedicles, concluding that the lamina and inferior articular processes “may offer stronger fixation of the lumbar spine.”

“The surgical world of spine treatment has progressed through the years from what one might describe as maximally invasive to minimally invasive,” said Stephen H. Hochschuler, MD, chairman, Texas Back Institute; founding board member, Global Spine Initiative; advisory board member, Amplio Spine The KeyLift technology is perhaps among the most secure minimally invasive spinal fusion developments. I believe, when appropriately applied by both well-trained surgeons and interventionalists, it will rise quickly to a preferred technique.”
