The Milestone Spinal System is indicated for interbody fusion with autogenous bone graft in patients with degenemative disc disease (DDD) at one or two levels from L2 to SI. These DDD patients may also have up to Grade I Spondylolisthesis or retrolisthesis at the involved level. These patients should be skeletally mature and have had six months of non-operative treatment. These implants may be implanted via an open or a minimally invasive posterior approach. Alternatively, these implants may also be implanted via transforaminal approach. These implants are to be used with aulogenous bone graft.
DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies.
These devices are intended to be used with supplemental fixation instrumentation, which has been cleared by the FDA for use in the lumbar spine.
Indications for use as stated in the FDA summary.
