The KeyLift system, cleared under FDA 510(k) K232484, is designed for supplemental fusion in the non-cervical spine, specifically targeting conditions such as lumbar spinal stenosis, spondylolisthesis, and degenerative disc disease. Unlike traditional pedicle-based constructs, KeyLift attaches to the spinous processes and lamina. This approach is supported by research suggesting that these posterior elements offer superior bone mineral density and cortical thickness compared to pedicles, potentially providing more robust fixation.

Amplio Spine is rolling out the platform in two configurations: the KeyLiftXL for general lumbar anatomy and the KeyLiftXS, a slim-profile version engineered for the constrained geometry of the lumbosacral junction at L5–S1. Founder and CEO Joshua Lambert stated that the company’s immediate focus is on clinical adoption through evidence-based outreach rather than broad market noise. By leveraging the late Peter Harris’s engineering lineage and an established distributor network, the firm aims to integrate the technology into standard surgical workflows for spine specialists.
