Minimally invasive surgical procedures can be good options for treatment of herniated discs or compression fractures. Inova has the latest in minimally invasive spine surgical technologies including robot-assisted equipment and augmented reality instrumentation for spine surgeries.
Commonly Performed Spinal Surgery Techniques
Lumbar Disc Replacement and Cervical Disc Replacement
Lumbar and cervical disc replacements are similar in concept to hip or knee replacements. Surgeons remove the damaged, painful disc in the cervical or lumbar spine and replace it with a metal and plastic implant. The implant is designed to move like a normal disc and recreate spinal motion and function.
Laminaplasty is a procedure in which the lamina (the bony arches on the vertebrae) are cut free along one side and hinged open like a door to enlarge the spinal canal and relieve pressure on the spine.
A laminectomy removes the bony arches on one or more vertebrae to relieve pressure on the spinal cord or a nerve branching from the spinal cord.
Spinal fusion connects two or more vertebrae together and keeps them from moving until they have a chance to grow together, or fuse. Surgeons place metal screws into the vertebrae and attach them to metal plates or rods that are bolted together in the back of the spine. Bone is grafted into the spaces between the vertebrae.
This device is a shock absorber that fits between two vertebrae to provide cushioning and stability, and relieve pressure on the spine.
Microendoscopic Discectomy for Herniated Discs
Surgeons insert a tiny metal tube to access the herniated disc and remove the portion pressing on the nerve. Muscle is displaced rather than cut, so when the tube is removed, the muscle falls back into its natural location.
Kyphoplasty for Compression Fractures
Surgeons insert a balloon tamp at the site of the compression fracture and inflate it, pushing the bone back to its normal height and shape. The cavity is filled with bone cement. When it hardens, the tubes are removed.
