The FOCUS Interbody System is intended to be used as a lumbar intervertebral fusion device at one or two adjacent levels from L2 to S1. This system should be limited to skeletally mature patients who have had six months of non-operative care for the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis or retrolisthesis at the involved spinal level(s). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. In addition, the FOCUS Interbody System can be used as an adjunct to fusion in patients diagnosed with degenerative scoliosis. The FOCUS Interbody System is intended for use with autograft and/or allograft comprised of cancellous and/or corticocancellous bone graft and/or demineralized allograft bone with bone marrow aspirate. These implants are intended for use with supplemental fixation indicated for lumbar spinal fusion procedures such as the OrthoCircle Spine Pedicle Screw System.
Indications for use as stated in the FDA summary.
