Engineered to Expand

A New Approach to
Interlaminar Fixation

KeyLift® is the first and only expandable interlaminar stabilization system FDA-cleared that is indicated for single-level supplemental fusion in the non-cervical spine (T1–S1).

The Problem

Traditional Interspinous Fixation Depends Heavily on the Spinous Process

Published biomechanical literature has reported lower failure strength in the spinous process compared with the lamina, highlighting the importance of fixation strategies designed to incorporate lamina engagement.

*Reported in published literature. Data may vary by device type, study design, patient population, testing method, bone quality, and follow-up period. Bench and clinical literature involving other devices may not predict KeyLift outcomes.

The Solution

Lamina-Engaging Interlaminar Support

KeyLift is designed for posterior non-pedicle supplemental fixation with lamina engagement and spinous process fixation/attachment, consistent with its cleared indication.

Support

Lamina-engaging interlaminar placement is designed to support posterior non-pedicle supplemental fixation.

Lift

An expanding distal end increases height between the vertebral bodies at the treated level.

Stabilize

Designed for supplemental fusion with autograft or allograft bone.

Why KeyLift

How KeyLift Compares

KeyLift combines expandable interlaminar placement with posterior non-pedicle supplemental fixation
for single-level use in the non-cervical spine, T1–S1.

Expandable

An expanding distal end increases height between vertebral bodies, with multiple implant heights available to accommodate patient anatomy.

Interlaminar

Designed for posterior placement between the lamina and spinous processes, with lamina engagement and spinous process fixation/attachment.

Supplemental Fusion

FDA-cleared for supplemental fusion with autograft or allograft bone. 

BIOMECHANICAL DATA

Biomechanical Bench Testing — Failure Strength (N)

Published biomechanical data have reported higher laminar failure strength compared with the spinous process. KeyLift is designed for posterior non-pedicle supplemental fixation with lamina engagement and spinous process fixation/attachment, consistent with its cleared indication.

  • Reported Laminar Failure Strength: 1,966 N 80% 80%
  • Reported Spinous Process Failure Strength: 405 N 20% 20%
*Values reported in published biomechanical literature. Testing methods, loading direction, vertebral level, bone quality, and specimen characteristics may vary. Bench and biomechanical data may not predict clinical outcomes. KeyLift™ has not been clinically proven to reduce fracture, migration, or reoperation compared with other devices.

CLEARED INDICATIONS

Single-Level Supplemental Fusion for Non-Cervical Spine Conditions

KeyLift is FDA-cleared as a posterior non-pedicle supplemental fixation device for single-level use in the non-cervical spine, T1–S1. It is intended for use with autograft or allograft bone and is not intended for stand-alone use.
