Non-Pedicle Screw Fixation
When used as an anterior spinal system the Thoracolumbar Spinal Rod System is intended for the treatement of DOD (degenerative disc disease defined as back pain of discogenic origin with degeneration of the disc confirmed by history or radiographic studies), pseudoarthrosis, stenosis, deformities (scoliosis, kyphosis, lordosis), spondylolisthesis, fracture, previous failed fusion, or tumor resection. The Thoracolumbar Spinal Rod System is limited to non-cervical use.
When used as a posterior, non-pedicie spinal system (consisting of hooks and sacralliliac screws), the Thoracolumbar Spinal Rod System is intended for the treatement of DDD (degenerative disc disease defined as back pain of discogenic origin with degeneration of the disc confirmed by history or radiographic studies), pseudoarthrosis, stenosis, deformities (scoliosis, kyohosis, lordosis), spondylolisthesis, fracture, previous failed fusion, or tumor resection. The Thoracelumbar Spinal Rod System is limited to non-cervical use.
Pedicle Screw Fixation
When used as a pedicle screw system, in the spine of skeletally mature patients, the Thoracolumbar Spinal Rod System is indicated for patients: (a) having severe spondylolisthesis (Grades 3 and 4) at the L5-S1 joint; (b) who are receiving fusions using autogenous btone graft only; (c) who are having the device fixed or attached to the lumbar and sacral spine (L3 and below); and (d) who are having the device remaved after the development of a solid fusion mass.
In addition, when used as a pedicle screw system, in the non-cervical spine of skeletally mature patients, the Thoracolumbar Spinal Rod System is intended to provide immobilization and stabilization of spinal segments, as an adjunct to fusion, in the treatment of the following acute and chronic instabilities of the thoracic, lumbar, and sacral spine: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphesis, spinal tumor, and failed previous fusion (pseudarthrosis).
