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.
The Camber TLIF (Transforaminal Lumbar Interbody Fusion) device is a single-component device manufactured from PEEK-OPTIMA, with one tip and two anterior-posterior titanium-alloy imaging markers. Titanium coating is plasma sprayed onto the device integration surfaces.
The Camber is anatomically shaped to fit the lumbar disc space optimally, with two different lengths and multiple heights to restore disc height. The tapered nose makes insertion of the device simpler. The titanium-coated surfaces and large bone graft window improve osseointegration with the vertebral endplates and bone graft, resulting in a more stable construct. The procedure for insertion of the Camber is simple and time efficient, with easy-to-use instrumentation that allows a minimally invasive approach when used in conjunction with the SOLFIX MIS system. The placement instrument, along with a titanium alloy hinge in the device, facilitates pivoting between the vertebral bodies and results in a smaller surgical incision. It is recommended to augment the Camber with supplemental posterior fixation using the SOLFIX2/ SOLFIX MIS pedicle screw and rod systems.
