## Indications for use
When used as a lumbar intervertebral fusion device, TrellOss™-L MPF is indicated for use at one or two contiguous levels in the lumbar spine, from L2-S1, in skeletally mature patients who have had six months of non-operative treatment 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. Additionally, TrellOss™-L MPF can be used as an adjunct to fusion in patients diagnosed with degenerative scoliosis. TrellOss™-L MPF is intended for use with autograft and/or allograft comprised of cancellous and/or corticocancellous bone graft and with supplemental fixation. TrellOss™-L MPF interbody implants with 14° lordosis or greater are only indicated for lumbar levels L2–L5 and are to be used with at least a 1-hole Timberline® MPF plate and screw construct.
