The Signature Orthopaedic C-Zero Pedicle Screw System and Freedom Pedicle Screw System are 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 and deformities of the thoracic, lumbar, and sacral spine: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis, trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis and/or lordosis); tumor; and failed previous fusion (pseudarthrosis). In addition, the C-Zero Pedicle Screw and Freedom Pedicle Systems are intended for skeletally mature patients in the treatment of severe spondylolisthesis (Grades 3 and 4) of the L5-S1 vertebra and degenerative spondylolisthesis with objective evidence of neurologic impairment.
