Minimally invasive lumbar surgery is a surgical technique that may be performed to treat degenerative disc disease, tumor, spinal stenosis and spinal infections. This technique includes surgical procedures like lumbar fusion, lumbar discectomy and lumbar laminectomy. Dr. Andrew K. Simpson provides personalized nonsurgical and surgical treatment for a wide range of spine conditions in Chestnut Hill, Boston, and Foxborough, MA. He also provides specialized aftercare for patients. Contact Dr. Simpson for an appointment today.
Spinal surgery can be performed by two different approaches; one is the conventional open surgical approach and the other is the advanced minimally invasive approach. Each approach has its own advantages and preferences. However, the minimally invasive technique is a more advanced approach with a higher success rate and a minimal level of patient discomfort.
A minimally invasive technique is more beneficial for a few lumbar surgeries. Some of the common minimally invasive lumbar surgical procedures include lumbar discectomy, lumbar fusion, and lumbar laminectomy.
Procedure for Minimally Invasive Lumbar Surgery
As compared with the conventional open surgery, minimally invasive surgery requires small incisions and highly advanced tools for the surgery, which hasten the recovery and decrease the chances of damage to the surrounding soft tissues. The basic steps involved in minimally invasive lumbar surgery are as follows:
- X-ray imaging is employed to decide the precise location of the small incisions, to approach the affected segment of the spine.
- Specially designed portals called trocars are then inserted through these incisions to aid in the use of the operating instruments.
- The entire procedure is conducted under fluoroscopic guidance.
- During the surgery, real-time X-ray imaging through the C arm assists in the use of specially designed instruments such as sextant device. Sextant device is employed for drilling a tunnel into the spine for fixing the screws and plates which stabilize the spine.
- After the procedure, all the instruments along with the portals are removed and the incisions are closed with surgical glue.
Advantages of Minimally Invasive Surgeries
Minimally invasive lumbar surgery has many advantages over the conventional surgical procedure, which include:
- Minimal damage to the adjacent tissues
- Reduced post-operative pain
- Reduced hospital stay
- Shorter recovery phase
- Reduced blood loss
- Minimal patient stress
The patient who undergoes a minimally invasive surgery requires a shorter period of post-operative care as compared to that of a patient undergoing open surgery. The post-operative instructions depend upon the type of surgery. However, a few general instructions for patients after a minimally invasive lumbar surgery include:
- Keep the incision clean and dry
- Avoid movements such as bending and twisting, for at least 6 weeks
- Regular intake of the prescribed medications
- Avoid lifting heavy objects
Risk Associated with Minimally Invasive Surgeries
As with open surgery, the possible risks associated with minimally invasive surgery include infection, reaction to anesthesia, bleeding, and damage to the spinal nerves during the procedure.
