A lumbar disk replacement is a type of back or spine surgery. Your spine is made up of bones called vertebrae that are stacked on top of each other. Disks between the vertebrae work like cushions to allow the vertebrae to rotate and move without rubbing against each other. The lumbar vertebrae and disks are at the bottom of your spine. Lumbar disk replacement involves replacing a worn or degenerated disk in the lower part of your spine with an artificial replacement made of metal or a combination of metal and plastic.
Lumbar disk replacement is a relatively new procedure to relieve low back pain. It’s generally seen as an alternative to the more common spinal fusion surgery that permanently joins two vertebrae together. Lumbar disk replacement is a major surgery that requires general anesthesia and a hospital stay.
The main reason you would need a lumbar disk replacement is to treat low back pain. Still, not everyone with low back pain is a good candidate for a lumbar disk replacement surgery. Your doctor will need to do some tests to determine if it’s the right procedure for you.
In general, lumbar disk replacement surgery might be recommended if:
Like all surgeries, lumbar disk replacement poses some risks. A disk replacement requires greater access to the spine than standard lumber fusion surgery. This also makes it a riskier procedure.
Some of the potential risks of this surgery include:
There may be other risks, depending on your specific medical condition. Be sure you understand the risks and benefits of lumbar disk replacement and discuss any concerns with your surgeon before the procedure.
Along with a physical exam and medical history, you may need X-rays, an MRI and/or CT scan, and blood tests. These help the doctor identify the true nature and extent of your back pain and spinal damage. They may also be needed to get a better view of the spine and decide whether you are able to get the surgery and whether it’s right for you.
You may be asked to stop smoking as part of getting ready for spine surgery.
Tell your doctor about all prescription and over-the-counter medications and any vitamins, herbs, and supplements that you are taking. Some of these may affect things like healing and blood clotting, so you may need to stop taking them before the procedure.
You may be told to not eat or drink anything for several hours before the surgery. You will probably have to stay in the hospital for a few days, and may not be allowed to drive for some time after surgery. You may need some help at home (with things like bathing, dressing, cleaning, and shopping) for a short time after surgery, so you may want to arrange this ahead of time.
Talk to your healthcare provider so you know exactly what you need to do before your procedure.
You will have an IV line put into a vein in your hand or arm through which an anesthetic is given. The medicine will put you into a deep sleep and keep you from feeling pain during the surgery. You will be lying on your back for this surgery.
A team of surgeons (usually a vascular surgeon and an orthopedic or neurosurgeon) will perform the disk replacement together. The surgeon will make an incision in your abdomen. Your organs and blood vessels will be moved to the side to allow access to your spine.
The surgeon will remove the damaged disk and put the new artificial disk in place. Your organs and blood vessels will be allowed to go back in place and the incision will be closed.
You will be taken to a recovery area for close monitoring until you are awake from the anesthesia. You will still have an IV line and may also have a catheter in your bladder to make urination easier. When you are fully awake and alert, you will be taken to your hospital room.
Talk with your healthcare provider about what you can expect your lumbar disk replacement procedure to be like.
You will probably need to stay in the hospital for a few days after your lumbar disk replacement surgery. Because a lumbar disk replacement doesn’t require bone to heal, the recovery period may be faster than with other back surgeries. You’ll be given pain medicines if you need them, and may be encouraged to stand and walk within the first day after surgery. Your IV and bladder catheter will be removed within a few days of surgery.
You will be shown how to move properly and how to do exercises, such as gentle trunk twists. This will keep your spine limber and help you have a quicker rehabilitation and recovery. As your recovery progresses, you’ll be encouraged to walk and stretch. You’ll need to avoid any jarring activities or motions for quite awhile. Your recovery may take from a few weeks to a few months.
A lumbar disk replacement generally improves pain, but it does not eliminate it completely. Talk with your doctor to get a realistic idea about what you can expect after this surgery. Also talk to your healthcare provider about instructions you need to follow after surgery, what you can and cannot do, how to care for your incision, signs of problems you need to watch for, and when you need to follow-up with the doctor.
