Read the full statement (120 words)
The EARP Interbody System is intended for intervertebral body fusion in the lumbar spine in
skeletally mature patients with degenerative disc disease (DOD) at one or two contiguous levels
from L2 to S1 of the lumbosacral spine. DOD is defined as back pain of discogenic origin with
degeneration of the disc confirmed by history and radiographic studies. These patients should have
had six months of non-operative treatment prior to treatment with an intervertebral cage. DOD
patients may also have Grade 1 spondylolisthesis or retrolisthesis at the involved levels. The device
system must be used with supplemental fixation and autograft and/or allogeneic bone graft
composed of cancellous, cortical, and/or corticocancellous bone to facilitate fusion and are
implanted via a posterolateral approach.
Indications for use as stated in the FDA summary.
