The Wenzel Spine VariLift-C Interbody Fusion System is indicated for use in skeletally mature patients with cervical disc degeneration (DDD) and/or cervical spinal instability, as confirmed by imaging studies (radiographs, CT, MRI) that
results in radiculopathy, myelopathy, and/or pain at one or multiple contiguous levels from C2/C3 to C7/T1. These DDD
patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s).
The Wenzel Spine VariLift-C Interbody Fusion System is used to facilitate intervertebral body fusion in the cervical spine
and is placed in a unilateral or a bilateral fashion via an anterior approach using autogenous and/or allogeneic bone graft
comprised of cancellous, and/or corticocancellous bone graft, or a bone void filler as cleared by FDA for use in
intervertebral body fusion to facilitate fusion. When used at one disc level, the Wenzel Spine VariLift-C interbody Fusion
System may be used with or without supplemental fixation. When used at multiple contiguous levels, the Wenzel Spine
VariLift-C Interbody Fusion System is intended to be used with supplemental fixation. Patients should have at least six (6)
weeks of non-operative treatment prior to treatment with an intervertebral fusion device.
Indications for use as stated in the FDA summary.
