Spinal decompression surgery is a general term that refers to various procedures intended to relieve symptoms caused by pressure, or compression, on the spinal cord and/or nerve roots. You have several options, including a corpectomy, a discectomy, a laminotomy, a foraminotomy, or osteophyte removal.
Spinal Disc Replacement
It is a type of spine surgery that is used to treat the herniated disc in the vertebrae. A disc separates two vertebrae and if it herniates inwards it presses on the spinal nerves causing pain. In discectomy all or part of the disc is removed.
A surgical technique used to join two vertebrae. Spinal fusion may include the use of bone graft with or without instrumentation (eg, rods, screws). There are different types of bone graft, such as your own bone (autograft) and donor bone (allograft). A fusion can be accomplished by different approaches:
ALIF, PLIF, TLIF, LIF: All pertain to lumbar interbody fusion used to stabilize the spinal vertebrae and eliminate movement between the bones.
- Anterior Lumbar Interbody Fusion
- Posterior Lumbar Interbody Fusion
- Transforaminal Lumbar Interbody Fusion indicates a surgical approach through the foramen.
- Lateral Interbody Fusion in which the minimally invasive approach is from the side of the body.
Examples of spinal instrumentation include plates, bone screws, rods, and interbody devices; although, there are other types of devices your surgeon may recommend in treatment of your spinal disorder. The purpose of instrumentation is to stabilize or fix the spine in position until the fusion solidifies.
- An interbody cage is a permanent prosthesis left in place to maintain the foraminal height (eg, space between two vertebral bodies) and decompression following surgery.
- Interspinous process devices (ISP) reduce the load on the facet joints, restore foraminal height, and provide stability in order to improve the clinical outcome of surgery. An advantage of an ISP is that it requires less exposure to place within the spine and therefore is a MISS procedure.
- Pedicle screws help to hold the vertebral body in place until the fusion is complete.
