## Indications for use
1. CAVUX Facet Fixation System (CAVUX FFS): CAVUX Facet Fixation System (CAVUX FFS) is posterior spinal instrumentation with integrated screw fixation intended to provide immobilization and stabilization of spinal segments. CAVUX FFS is placed bilaterally through a posterior surgical approach and spans the interspace with points of fixation at each end of the construct. CAVUX FFS is intended for temporary stabilization as an adjunct to posterior cervical fusion in skeletally mature patients. CAVUX FFS is indicated for patients requiring a revision for an anterior pseudarthrosis at one level, from C3 to C7, with autogenous and/or allogenic bone graft. 2. CORUS-LX Implant: CORUS-LX Implant is posterior spinal instrumentation with integrated screw fixation intended to provide immobilization and stabilization of spinal segments. CORUS-LX is placed bilaterally through a posterior surgical approach and spans the facet interspace with points of fixation at each end of the construct. CORUS-LX is intended to provide temporary stabilization as an adjunct to a 1 or 2 level interbody lumbar fusion with autogenous and/or allogenic bone graft and must be accompanied with an FDA cleared intervertebral body fusion device implanted at the same spinal level(s), and may be used with a pedicle screw and rod system implanted at the same spinal level(s). CORUS-LX is indicated for the treatment of patients with lumbar degenerative disc disease (DDD) from L4 to S1 in skeletally mature patients who have failed conservative care.
