Why KeyLift®
Three Engineering Choices that Define the System.
Built on a Proven Category. Engineered to Move it Forward.
Interlaminar supplemental fixation has a decade-plus history in lumbar spine surgery as a less‑invasive way to support segmental fusion after decompression. KeyLift was engineered as the next generation of that approach. Cleared by FDA as the KeyLift Expandable Interlaminar Stabilization System — a posterior, non‑pedicle supplemental fixation device intended for use with bone graft to achieve supplemental fusion in the non‑cervical spine — KeyLift advances the category where it matters most:
-
- True in‑situ expansion, for tailored intraoperative fit
- A laminar load path, anchoring to the strongest posterior bone of the spinal column
- A purpose‑built L5–S1 construct, extending the approach into anatomy earlier interlaminar devices were not designed to address
KeyLift is not intended for stand‑alone use.
01
Support
Support at the lamina — not the spinous process. Fixates close to the instantaneous axis of rotation for a more mechanically stable construct.
02
Lift
In-situ expansion distracts up to 4 mm intraoperatively. Restores foraminal height and decompresses the neural elements without aggressive bone removal.
03
Stabilize
Positioned close to the spine’s instantaneous axis of rotation, balancing the intervertebral disc and promoting a stable, biomechanically favorable fusion environment.
Designed for the Realities of the Procedure
Every reason a physician chooses the predicate over fusion, smaller incision, faster case, minimally invasive posterior approach, and supplemental fixation without pedicle screws, is consistent with KeyLift’s design intent. What KeyLift adds is the ability to distract intraoperatively and the only configuration in the platform engineered specifically for L5–S1, alongside the T1–L5 KeyLift XL.
