What is it indicated for?

The CastleLoc-P 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.
