Anterior Lumbar Devices
The main method of motion preservation for the lumbar spine is total disc replacement, there are many different devices that can be used for this type of disc replacement along the anterior. They all vary in size or shape, and their use depends upon your specific needs. Common devices include the Charite device, the FlexiCore device, and the NuVasive XL. Total disc replacement for the lumbar spine isn’t without its possible complications, hemorrhage, vascular injury, infection, peritoneal entry, or vertebral fracture are all possible, however, not likely.
For the anterior lumbar spine, partial disc replacement is also possible, this is known as Disc Nucleus Replacement. The damaged nucleus pulposus is replaced or augmented with an injectable or preformed device. However, devices for this type of procedure are rare, and often have to be retrofitted in some capacity. This procedure is rare.
Posterior Lumbar Devices
These devices can address pain that originates from posterior elements such as facet joints, ligaments, tendons, or muscles. They can also help in the treatment of spinal stenosis. There are three main types of posterior devices:
- Interspinous Process Spaces: Used to open the central canal and the opening of the nerve roots along the spinal canal, known as the foramen. Help with pain as well as restricted movement. The main benefit of these devices is that they can be implanted in a relatively quick, less-invasive procedure.
- Dynamic Stabilization Devices: These devices act similar to an internal brace for the spine, allowing for more controlled motion, and relatively normal movement. They are typically used to treat patients with spondylolisthesis and degenerative disc disease.
- Facet Replacement or Total Element Replacement Devices: Facet replacement devices replace the facet joints in the back of the spine to limit or control motion, while total element replacement devices replace all the elements in the back of the spine.
