Read the full statement (329 words)
The aprevo® anterior lumbar interbody fusion device with interfixation (ALIF-X) is intended for
interbody fusion in skeletally mature patients and is to be used with supplemental fixation
instrumentation cleared for use in the lumbar spine. The aprevo® anterior lumbar interbody fusion
device with interfixation is indicated for use as an adjunct to fusion at one or more levels of the
lumbar spine in patients having an ODI >40 and diagnosed with severe symptomatic adult spinal
deformity (ASD) conditions. These patients should have had six months of non-operative treatment.
The devices are intended to be used with autograft and/or allogenic bone graft comprised of
cancellous bone and/or cortico-cancellous bone. These implants may be implanted via a variety of
open or minimally invasive approaches. The aprevo® anterior lumbar interbody fusion device with
interfixation is intended to be used with the screws that accompany each implant and with
supplemental fixation.
The aprevo® anterior lumbar interbody fusion device with interfixation (ALIF-X) is indicated for use at
one or more levels of the lumbosacral spine as an adjunct to fusion in patients with the following
indications: degenerative disc disease (DDD), disc herniation (with myelopathy and/or
radiculopathy), spondylolisthesis, deformity (degenerative scoliosis or kyphosis), spinal stenosis, and
failed previous fusion (pseudarthrosis). DDD is defined as discogenic back pain with degeneration of
the disc as confirmed by history and radiographic studies. These patients should be skeletally mature
and have had at least six (6) months of non-operative treatment. aprevo® lumbar interbody fusion
devices are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or
corticocancellous bone. These devices are intended to be used with supplemental fixation systems
that have been cleared for use in the thoracolumbosacral spine (e.g., posterior pedicle screw and rod
systems). These implants may be implanted via a variety of open or minimally invasive approaches.
The aprevo® anterior lumbar interbody fusion device with interfixation is intended to be used with the
screws that accompany each implant and with supplemental fixation.
