The Wenzel Spine VariLift Lumbar Interbody Fusion Device is a self-tapping, expandable device with an interior sliding wedge and a posterior end cap. The VariLift-L is a grooved and fluted device with large graft windows positioned each of its four quadrants that provide bony contact with the endplates. VariLift-L is designed to be implanted bi-laterally via posterior (PLIF) approach or as a single device via a transverse (TLIF) approach. VariLift-L may be implanted with or without supplemental fixation and is intended for use with autograft to facilitate fusion. VariLift-L is indicated for intervertebral body fusion of the lumbar spine, from L2 to S1, in skeletally mature patients who have had six months of non-operative treatment. The device is intended for use at either one level or two contiguous levels for the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies.
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.
