Laser Spine Surgery vs. Minimally Invasive Spine Surgery

I often see patients for consultations who ask me about laser spine surgery and minimally invasive spine (MIS) surgery. Frequently this question comes from a spine patient who needs surgery and has heard about the now-closed Laser Spine Institute or about MIS surgery. The two are often confused, but they are not the same — and the difference matters when you are deciding on treatment.

What laser spine surgery really was

The Laser Spine Institute (LSI), formerly based in Tampa, Florida, promoted the use of a laser to perform spinal surgery through smaller and smaller incisions. The idea was that patients would recover faster and return to their daily activities more quickly. One of LSI’s print ads showed a young woman on the beach with a band-aid covering her spine surgery incision — the message being that with laser spine surgery, a patient could have surgery through a tiny incision and quickly get back to normal life.

In reality, laser spine surgery was more of a marketing tool than a distinct procedure. The laser was used mainly as an instrument to remove tissue, and that limited its role and function. The laser:

• Could not help in cases where spinal alignment correction or instrumentation is needed to stabilize the spine
• Had limited value when surgery required extensive exposure of the spine

Why traditional surgery meant a hard recovery

Traditional spinal surgery usually requires large incisions to expose the spine. As a result of those large incisions, patients often experience significant post-surgery pain and a slow recovery. For many patients, that made spine surgery a scary proposition — big incisions, long surgical times, and a long recovery period.

What minimally invasive spine surgery (MIS) actually delivers

Unlike laser surgery, minimally invasive spine surgery offers real, measurable patient benefits. The goal of MIS is to limit how much the spine is exposed and to limit soft-tissue disruption. By limiting tissue disruption during surgery, the patient has much less pain — which leads to a quicker recovery and a faster return to normal activities.

The advantages of MIS come from a few key tools and techniques working together:

• Smaller, focused incisions with less tissue and muscle disruption, making the procedure more precise
• The surgical microscope and specialized instruments, which allow the surgeon to operate through a much smaller incision
• Specialized anesthesia, which allows most patients to recover without significant pain and go home the same day

Because of these advances, spine surgery has changed from a procedure that required a hospital stay of two to three days to one that can often be done in an outpatient facility, with the patient returning home the same day. This faster, less painful recovery has been a major advance in treating patients with spinal disorders that require surgery.

The bottom line

The laser used in spine surgery is simply an instrument to remove tissue, and laser spine surgery is very limited in what it can do. The goals of a quicker procedure and faster recovery are better achieved with minimally invasive spine surgery. MIS uses a more focused, targeted incision combined with tools like the microscope and specialized anesthesia to ensure less pain and a faster return to normal activities. For these reasons, MIS — not laser surgery — has become the preferred technique for treating surgical spinal disorders.
