Southern Anterior Screw Fixated Cages are indicated for use as stand-alone anterior interbody fusion devices in the lumbar spine. The devices are designed to be used with the bone screws provided and the interior cavity must be filled with autograft. Supplementary spinal fixation is not required.

The devices are indicated for use in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L1 to S1. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. These DDD patients may also have up to Grade I spondylolisthesis at the involved level(s). The devices may also be used in patients with pseudarthrosis / non-union from previous unsuccessful fusion surgery. Patients should have undergone at least six months of non-operative treatment.

Indications for use as stated in the FDA summary.
