Read the full statement (106 words)
The intended use of the Mariner Pedicle Screw System in a posterior or anterolateral approach is 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 or deformities of the thoracic, lumbar, and sacral spine.
The indications for use are as follows:
degenerative disc disease (DDD) as defined by back pain of discogenic origin with degeneration of the disc confirmed
by patient history and radiographic studies,
spondylolisthesis,
trauma (i.e., fracture or dislocation),
spinal stenosis,
deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis),
spinal tumor,
pseudarthrosis, and/or
failed previous fusion.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
