The Wenzel Spine VariLift-LX Interbody Fusion Device is a self-tapping, expandable device with an interior sliding wedge and a posterior end cap. The VariLift-LX is a grooved and fluted device with large graft windows positioned each of its four quadrants that provide bony contact with the endplates. VariLift-LX is designed to be implanted bi-laterally via a PLIF or TLIF approach, and may be implanted with or without supplemental fixation.
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.
