Summary

Amplio Spine, LLC announced on June 18, 2026, the acquisition and national commercialization launch of the KeyLift® Expandable Interlaminar Stabilization System from FloSpine, LLC. This FDA-cleared (K232484) device is a posterior, non-pedicle, supplemental fixation system for single-level use in the non-cervical spine (T1–S1). It is indicated for plate fixation/attachment to the spinous processes/lamina to achieve supplemental fusion in conditions like lumbar spinal stenosis, degenerative disc disease, spondylolisthesis, trauma, and tumor, always with allograft or autograft bone. KeyLift is unique within its FDA classification (21 CFR 888.3050, Class II, product code PEK) for its "expandable" attribute and specific fixation method. The system is offered in two configurations, KeyLiftXL for lumbar anatomy and KeyLiftXS for lumbosacral anatomy, across eight sizes. Anatomic research supports its design, indicating stronger bone density in the lamina compared to pedicles.

Key takeaway

For spine surgeons and interventionalists evaluating supplemental fusion systems, KeyLift® presents a unique, FDA-cleared option targeting the lamina and spinous processes for potentially stronger fixation. You should assess its utility for single-level non-cervical spine cases, particularly for conditions like lumbar spinal stenosis or degenerative disc disease, where its expandable design and specific fixation method may offer advantages over traditional pedicle-based constructs. Consider reviewing the device's Indications for Use and available clinical training.
