What is it indicated for?
The MIS Z-Pedicle Screw System is intended to provide immobilization and stabilization of the spinal segments for posterior, non-cervical pedicle fixation in skeletally mature patients as an adjunct to fusion for the following indications:
degenerative disc disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies);
spondylolisthesis (grades 3 and 4) at L5-S1
trauma (i.e., fracture or dislocation)
spinal stenosis
curvatures (i.e.,scoliosis, kyphosis, and/or lordosis)
tumor
pseudoarthrosis
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.
