Depending on the extent and type of surgery necessary, incisions can often be small. Once the procedure is complete, the tubular retractor can be removed, allowing the dilated tissues to come back together. Sometimes, the surgeon will also utilize an endoscope or microscope focused down the tube to assist with performing the surgery through a minimal access strategy. By using tubes to keep the muscles out of the way, the surgeon works through the incision without having to expose the area widely. This technique involves progressive dilation of the soft tissues, as opposed to cutting directly through the muscles. Localized infections, no matter how small the incision areaĪnd, though uncommon, there is always a small chance that the initial MIS surgery cannot be completed, requiring either a second procedure or full open surgery. Unexpected blood loss during the procedure.Possible adverse reaction to the anesthetic.In addition, some MIS surgeries are performed as outpatient procedures and utilize only local anesthesia - so there is less risk for an adverse reaction to general anesthesia.Īs with any surgical procedure, no matter how minimal, there are certain risks associated that include, but are not limited to: Diminished reliance on pain medications after surgery.Faster recovery from surgery and less rehabilitation required.Reduced risk of infection and postoperative pain.Reduced risk of muscle damage, since less or no cutting of the muscle is required.Better cosmetic results from smaller skin incisions (sometimes as small as several millimeters).Because of the reduced trauma to the muscles and soft tissues (compared to open procedures), the potential benefits are: In general, the goal of minimally invasive spine (MIS) surgery is to stabilize the vertebral bones and spinal joints and/or relieve pressure being applied to the spinal nerves - often a result of conditions such as spinal instability, bone spurs, herniated discs, scoliosis or spinal tumors.Īs opposed to open spine surgery, minimally invasive surgical approaches can be faster, safer and require less recovery time.
