Stand-alone Fusion for Degenerative Spine

The S-LIF Procedure using VariLift®-LX and S-ACDF using VariLift®-C are true MIS alternatives to traditional spine fusion techniques, requiring significantly less hardware while preserving healthy anatomy.

Why Choose Stand-alone?

VariliftFusion_Benefits

We have partnered with 300+ surgeons across the U.S. to provide a simple, alternative approach for spine fusion procedures. VariLift® is the only FDA-cleared expandable solution for stand-alone posterior lumbar and cervical interbody fusion that can be used with or without supplemental fixation.

Stand-Alone Solution

FDA-Cleared and On-Label Stand-Alone TLIF, PLIF, ACDF Procedure

Expands in Situ

Restores up to 8-9º segmental lordosis in lumbar, 7º in cervical

Zero Impact Insertion

Insert device without disrupting the cortical endplates

Generous Graft Chamber

Substantial graft capacity for ultimate fusion growth

Broadest Clearance for Patient Optimization

VariLift® provides proven clinical outcomes and fewer postoperative complications, allowing surgeons to approach any existing procedure conservatively.

MIS-TLIF, Single-Incision PLIF, Zero-Profile ACDF
1 or 2 Level Stand-Alone for Lumbar, 1 Level Stand-Alone for Cervical
With or Without Fixation
Inpatient or Outpatient, ASC-Friendly

Flexible Treatment Option for Adjacent Segment Disease

Significant clinical success and high fusion rates for the treatment of symptomatic ASD cases. Proven to reduce VAS scores and clinical symptoms without the need for supplemental fixation.

A) Pre-operative MRI showing ASD, B) Post-operative lateral radiograph, C) Post-operative A/P radiograph with placement of the 2 standalone devices at L2-3 and L3-4 and continued presence of the pre-existing anterior/posterior fusion construct.

Designed to Resist Migration and Subsidence

The VariLift® surgical technique advances the device into the disc in a manner that preserves the endplate cortical bone and limits causes of subsidence. Clinical experience with VariLift^® has demonstrated a very low subsidence rate that is further supported by bench-top subsidence testing per ASTM standards³⁰ and FEA studies comparing the VariLift^® device to cylindrical cages.²³As the VariLift®-LX is expanded, the near cylindrical shape of the device becomes wedged with 7º (cervical) to 8-9º (lumbar) of lordosis. The grooves on the surface of the device provide stable primary fixation with the endplate surface to resist migration.

Expands in Situ creating a Large Graft Chamber

Designed to Help Treat Collapsed Disc Spaces and Provide Immediate Stabilization

With a leading edge as small as 6mm for lumbar and 5mm for cervical, the VariLift® enters into the disc space in a near cylindrical shape and expands in situ. The expansion causes the device edges to gain further purchase into the cortical endplates and provide immediate stability while a large graft chamber allows for insertion and overpacking of material to promote fusion.

“My motto for my patients all along has always been ‘Faster Safer Better’ and VariLift®, as an FDA-approved stand-alone interbody, is the ultimate evolution of that.”
