What kind of doctor provides Minimally Invasive Spine Surgery?
A spine surgeon performs minimally invasive spine surgery. This is often an orthopedic surgeon, a bone and joint surgeon, or a neurosurgeon, a surgeon who treats the nerves and spine. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Minimally invasive spine surgery, also called MISS, reaches the spine through smaller cuts than open surgery. A smaller cut avoids significant damage to the muscles around the spine. The goal is to steady the spine bones and joints, take pressure off the spinal nerves, or both.
Why a doctor might recommend it
Doctors use MISS for problems such as a herniated disc, spinal stenosis, and spinal instability. A disc is a cushion between the spine bones. A herniated disc can press on nearby nerves and cause pain. Spinal stenosis is a narrowing of the vertebral canal that can squeeze nerves. The reasons for surgery are the same as for open surgery. Spine surgery is usually recommended only after a period of treatment without surgery.
How to prepare
Before surgery, these steps come first.
- Your doctor can tell you which MIS operations, if any, may be an option for you.
- Your doctor will go over each risk with you.
What happens during it
With general anesthesia, you are asleep for the whole operation. With regional anesthesia, you may be awake but have no feeling from the waist down. The most common method uses a tubular retractor. The surgeon makes a small cut. The retractor goes through the skin and soft tissues down to the spine. The tube keeps the muscles out of the way. The surgeon typically uses a microscope to view the spine. At the end, the tube is removed and the muscles return to their original position. Some surgeons use an endoscope, a small camera, to reach the problem area. Spinal fusion joins spine bones so they heal into one solid bone.
Recovery
In general, patients go home the same day or in 1 to 2 days. Your doctor may recommend physical therapy to help you regain strength. After a fusion, it may be several months before the bone is solid. Contact your surgeon if you have chills or a fever of 101°F (38.3°C) or higher. Also call for more pain where you had surgery or drainage from the wound. Also call for swelling or calf pain. Also call if back pain gets worse and does not get better with rest and pain medicine. Call 911 or go to the emergency room if you have trouble breathing, chest pain or discomfort lasting two minutes or more, fainting or loss of consciousness, or bleeding that will not stop.
Risks and side effects
As with any operation, MISS has risks. These include the following.
- Infection, which is why antibiotics are given around the time of surgery.
- Pseudarthrosis, where a spinal fusion does not fully heal, which may need a second surgery.
- Nerve or blood vessel injury, which is very rare.
- Blood clots in the legs, which are uncommon but can travel to the lungs.
Smokers are more likely to develop pseudarthrosis. Though uncommon, the surgery may not be finished as planned. This can mean a second procedure or open surgery.
Who performs it
A spine surgeon, such as an orthopedic surgeon or a neurosurgeon, performs minimally invasive spine surgery. Because the opening is smaller, the surgery is harder for the surgeon.
Common questions
How is minimally invasive spine surgery different from open surgery?
The main difference is that it uses smaller cuts and causes less muscle damage. Typically, this means less pain after surgery and a faster recovery.
How long is the hospital stay after minimally invasive spine surgery?
In general, the hospital stay is the same day or 1 to 2 days. In some cases, there is no hospital stay.
Is a laser used in minimally invasive spine surgery?
Lasers are very rarely used in these operations. Surgeons guide instruments or tiny video cameras through small cuts.
Can every spine problem be treated with minimally invasive surgery?
No, not every spine problem can be treated this way. In some situations, it may not be as safe or effective as open surgery.
How does a direct primary care or concierge doctor fit in?
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
