The Wenzel Spine VariLift-C Cervical Interbody Fusion Device System consists of a self-tapping, expandable device with an interior expansion plate, and is grooved and fluted with large graft windows positioned between each of its four quadrants that provide bony contact with the endplates. VariLift-C may be used with or without supplemental fixation. VariLift-C is indicated for use in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine with accompanying radicular symptoms at one disc level. DDD is defined as discogenic pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have at least six weeks of non-operative treatment prior to treatment with VariLift-C. These DDD patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level. The VariLift-C 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 at the C3 to C7 disc levels using autograft bone.
A device intended to be implanted into the space of an intervertebral disc that has been partially or totally removed during surgery in order to allow bone fusion between two contiguous vertebral bodies, typically in the treatment of degenerative disc disease (DDD). It is in the form of a hollow, porous, threaded and/or fenestrated cylindrical or geometrical device made of metal [e.g., titanium (Ti)] that provides mechanical stability and sufficient space for therapeutic spinal bone fusion to occur; bone graft is typically used to help with osseointegration. Fixation screws and devices associated with implantation may be included with the device.
