SASCA - Southern Anterior Screw Cage


  • Stable fusion construct using an anterior approach

  • Low imaging signature provides high quality post-operative MR images

  • Multiple heights in two footprints, with lordotic and scoliotic correction profiles

Procedure Description
Spinal fusion is performed in the treatment of severe back pain or a neurological deficit that has not responded to conservative treatment. The symptoms are caused by compression on a nerve or nerve root, commonly as a result of: damaged discs (discogenic pain or degenerative disc disease), abnormal slippage and motion of the vertebra (spondylolisthesis or spondylolysis), or other degenerative spinal conditions, including facet joint degeneration. Spinal fusion may be indicated for any condition that causes excessive instability of the spine, such as certain fractures, infections, tumours, and spinal deformity (such as scoliosis).

Treatment is achieved by decompressing the nerve and preventing motion at the effected segment and allowing for the adjacent vertebrae to permanently fuse.

Product Description
The Southern Anterior Screw Cage (SASCA™) comprises of a PEEK-OPTIMA body with posterior titanium-alloy imaging markers, and titanium-alloy bone-anchoring screws. It is provided with one superiorly angled screw hole and two inferiorly angled screw holes, as well as two cavities for bone inserts/bone graft.

The SASCA™ is anatomically-shaped to fit the lumbar disc space optimally, with two footprint sizes and multiple heights to restore disc height. Surface serrations prevent the device from being displaced between the vertebrae. The device is provided in two different lordotic angles for treatment of lordosis, as well as two scoliosis-correcting profiles. Large bone graft windows accommodate bone graft or synthetic bone inserts, improving osseointegration with the vertebral endplates. The bone-anchoring screws incorporate dual-start thread for quicker insertion, as well as locking thread that, while allowing for easier explantation if required, interferes with the screw holes to prevent screw back-out.
