What is it indicated for?
The OLYMPIC Posterior Spinal Fixation System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of thoracic, lumbar, and sacral spine (T1-S2/Ilium): degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, deformities or curvatures (i.e. scoliosis…
Read the full statement (192 words)
The OLYMPIC Posterior Spinal Fixation System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of thoracic, lumbar, and sacral spine (T1-S2/Ilium): degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, deformities or curvatures (i.e. scoliosis, kyphosis, and/or lordosis), spinal tumor, and failed previous fusion (pseudarthrosis). When used as an adjunct to fusion, the OLYMPIC Posterior Spinal Fixation System is intended to be used with autograft/allograft.
In addition, the OLYMPIC Posterior Spinal Fixation System is intended for treatment of severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft, having implants attached to the lumbosacral spine and/or ilium with removal of the implants after the attainment of a solid fusion. Levels of pedicle and non-pedicle fixation for these patients are L3-sacrum/ilium.
When used for posterior non-cervical pedicle and non-pedicle fixation in pediatric patients, the OLYMPIC Posterior Spinal Fixation System is intended to be used with autograft and/or allograft. Pediatric pedicle and non-pedicle fixation is limited to a posterior approach.
Indications for use as stated in the FDA summary.
