## Indications for use
The intended use of the Mariner Pedicle Screw System 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, - severe spondylolisthesis (Grades 3 and 4) of the L5-S1 vertebra in skeletally mature patients receiving fusions by autogenous bone graft having implants attached to the lumbar and sacral spine (L3 to sacrum) with removal of the implants after the attainment of a solid fusion, - spondylolisthesis, - trauma (i.e., fracture or dislocation), - spinal stenosis, - deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis), - spinal tumor, - pseudoarthrosis, and/or - failed previous fusion.
