It may be used alone or with other anterior, anterolateral, or posterior spinal systems made of compatible materials. This device is not intended for load bearing applications.

Device Story

LITe® Plate System is an anterior/anterolateral/lateral spinal fixation system; consists of titanium alloy plates and screws; used by surgeons in clinical settings to provide additional support during spinal fusion; implants available in various sizes to accommodate patient anatomy; buttress plate stabilizes allograft/autograft at one level; device provides temporary stabilization to aid fusion; not intended for load-bearing applications; system used alone or with other compatible spinal systems.

Clinical Evidence

Bench testing only. Risk analysis and mechanical testing performed, including static and dynamic compression testing (ASTM F1717-14), static torsion testing (ASTM F1717-14), and buttress plate expulsion testing. All predefined acceptance criteria were met.

Technological Characteristics

Materials: Titanium alloy (Ti6Al4V) per ASTM F136 and ISO 5832-3. Components: Plates and screws. Principle: Spinal intervertebral body fixation. Connectivity: None (manual surgical instrumentation).

Indications for Use

Indicated for skeletally mature patients requiring spinal fusion support for degenerative disc disease, pseudoarthrosis, spondylolysis, spondylolisthesis, spinal stenosis, tumors, trauma (fractures/dislocation), deformities (scoliosis, kyphosis, lordosis), or failed previous fusion. Buttress plate indicated for allograft/autograft stabilization at one level (T1-S1).

Regulatory Classification

Identification

A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.

Dear Dr. Hayeck:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
