Engineered to Expand

The First & Only Expandable
Interlaminar Fixation System

FDA-cleared expandable system. Expands in-situ to patient anatomy. Engages both laminae for stronger supplemental fixation. Single-level, T1–S1.

FDA cleared for use with clamp; representative image is shown of Implant without clamp for illustrative purposes. 

LAMINA VS. SPINOUS PROCESS

Why Lamina Engagement

Traditional interspinous fixation depends on spinous process strength. Laminae support 4.8x more load. KeyLift engages both.

STRONGER ANCHOR

Laminae sustain 1,966 N vs. spinous process at 405 N

ADJUSTABLE HEIGHT

Expands to patient anatomy—multiple heights available

SINGLE-LEVEL, T1–S1
FDA-cleared for trauma, tumor, stenosis, DDD, spondylolisthesis

BIOMECHANICAL DATA

Laminae Are 4.8x Stronger Than the Spinous Process

Laminae sustain significantly higher loads than the spinous process—the foundation for KeyLift’s design.

  • 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.
