The MOSS Miami Spinal System is intended for non-cervical use in the spine.

When used with anterior screw fixation or posterior hook, non-pedicle screw fixation the MOSS Miami Spinal System is intended to treat scoliosis, kyphosis and lordosis, fracture, loss of stability due to tumor, spinal stenosis, spondylohsthems a previously failed fusion surgery or clegenerative disc disease (i.e. dlscogemc back pain with degeneration of the disc confirmed by patient history and radiographic studies).

When used with pedicle screw fixation, the MOSS Miami Spinal System is intended for use in patients with severe spondylolisthesis (Grades 3 and 4) at the L5-S1 vertebral joint, having fusions with autogenous bone graft, with the device fixed or attached to the lumbar and sacral spine (levels of pedicle screw fixation are L3 and below), and for whom the device system is intended to be removed after the development of a solid fusion mass.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
