Read the full statement (211 words)

Internal fixation implants are load-sharing devices intended to stabilize and maintain alignment until normal healing occurs. Implants are not intended to replace normal body structures or bear the weight of the body in the presence of incomplete bone healing.

The Modular Spinal Fixation System, when properly used, is intended for posterior pedicle screw fixation of the non-cervical posterior spine in skeletally mature patients and for pediatric patients to treat adolescent idiopathic scoliosis (4.75 systems only). It provides stabilization and immobilization of spinal segments as an adjunct to fusion. Pediatric pedicle screw fixation is limited to a posterior approach.

When used as a posterior spine thoracic/lumbar system, the Modular Spinal Fixation System is indicated for one or more of the following: (1) degenerative disc disease (is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), (2) trauma (i.e. fracture or dislocation), (3) curvatures (scoliosis, kyphosis, and/or lordosis), (4) spinal tumor, (5) failed previous fusion (6) pseudarthrosis, (7) spinal stenosis, (8) spondylolisthesis.

In order to achieve additional levels of fixation in skeletally mature patients, the Modular Spinal Fixation System may be connected to the Solstice OccipitoCervicoThoracic Fixation System’s 3.5mm rod. The Modular Spinal Fixation System is intended to be used with autograft or allograft.

Indications for use as stated in the FDA summary.
