What is it indicated for?
The SMG Anterior Cervical Plate System is intended for anterior screw fixation to the cervical spine (C2-C7). The System is indicated for use in the immobilization and stabilization of the spine as an adjunct to fusions in patients with:
* degenerative disc disease (as defined by neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies),
* spondylolisthesis,
* trauma (i.e. fractures or dislocations),
* tumors,
* deformity (defined as kyphosis, lordosis, or scoliosis),
* failed previous fusion (pseudoarthrosis)
* spinal stenosis.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
