This web page is designed to inform you about the Maximum Access Surgery Transforaminal Lumbar Interbody Fusion (MAS TLIF) surgical procedure. It is not meant to replace any personal conversations that you might wish to have with your physician or other member of your healthcare team.
Not all the information here will apply to your individual treatment or its outcome. The information is intended to answer some of your questions and serve as a stimulus for you to ask appropriate questions about the procedure.
Lumbar interbody fusion is a surgical technique that attempts to eliminate instability in the back. A MAS TLIF achieves this by using a less invasive approach to fuse one or more vertebrae together to reduce their motion.
In a MAS TLIF procedure, rather than starting from the middle of the back and spreading the muscles to the sides like in a traditional back surgery, the MAS TLIF approach starts off to one side of the back and splits (rather than cuts) the back muscles in one direction. This allows the surgeon to make a smaller incision with less muscle injury, which may result in less postoperative pain and a quicker recovery.
What are the potential advantages of MAS TLIF*?
- Reduced blood loss and minimal scarring
- Reduced hospital stay
- Faster postoperative recovery time
- Smaller incision

Many of the symptoms can be treated without surgery with methods that involve medicine, rest, heat, and physical therapy. It is important that you speak to your physician about the best options for you.
If your symptoms do not improve with other methods, your physician may suggest spinal surgery. Surgery is reserved for those who do not gain relief from non-operative forms of treatment and/or patients whose symptoms are increasing or worsening.
Your physician might determine a MAS TLIF procedure is a good option for you if you require a spinal fusion at any lumbar level between L1 and S1, and you would benefit from a less disruptive approach.
Conversely, your physician may determine that a MAS TLIF procedure is not a good option for you. It is important to discuss this with your physician.
Are there risks involved?
All surgery presents risks and complications that are important to discuss with your physician prior to your surgery. Listening to your physician’s guidance, both before and after surgery, will help to ensure the best possible outcomes from your procedure.
Some of the most common complications following MAS TLIF surgery include: problems with anesthesia, infection, nerve damage, problems with the graft or hardware, and ongoing pain. This is not intended to be a complete list of the possible complications.
Your physician will review your condition and explain all of your treatment options, including non-operative treatments, such as medications and physical therapy. Once you have been admitted to the hospital, you will be taken to a pre-op room and prepared for surgery. This may include instruction about the surgery and cleansing of your surgical site, as well as instruction about the postoperative period.
Typically, your surgeon will make a small incision on one side of your back. The size of the incision can vary based on the number of levels and/or complexity of your case.
Your surgeon will then remove the disc to reduce pressure from the symptomatic cord or nerve root. An appropriate implant, chosen by your surgeon, will be placed into the disc space to restore the proper disc height and provide mechanical support while bone grows between the vertebral bodies during the fusion (bone healing) process. That segment of your spine will eventually stabilize once fusion occurs.
Screws will be placed into the vertebrae to provide stabilization to the spine. Once the screws have been placed on the MAS TLIF side, screws are also inserted on the opposite side of the vertebrae through one or two small skin incisions. These screws provide additional stability to help hold everything in place while fusion occurs. They are inserted through a small, minimally disruptive incision.
The final result will be a construct with an interbody implant between the vertebral bodies, where the fusion will occur, and screw and rod fixation on both sides to stabilize.
Patients usually require a stay of 1-2 days in the hospital. Your physician will discuss what is right for your particular case. The day after your surgery, your physician may instruct you to use a brace for a period of time to assist with the spinal fusion process. Supervised by trained medical professionals, your physician may ask you to carefully sit, stand, or walk within 24 hours of the surgery.
Once you are discharged from the hospital it is important to limit your activities for a period of time (determined by your healthcare provider) to give your body a chance to heal. Your physician will provide instructions on wound care, exercises, and limitations to postoperative activity.
CAN I SHOWER AFTER SURGERY?
Depending on your surgical incision, you may have showering restrictions. Ask your physician for appropriate instructions.
WILL I HAVE A SCAR?
Your physician will discuss the incisions that will be made during your MAS® TLIF surgery. Small scars of approximately one and a half inches are common.
WHEN CAN I DRIVE?
For a period of time after your surgery, you may be cautioned about activities such as driving. Your physician will tell you when you may drive again.
CAN I TRAVEL?
The implants used in the MAS TLIF procedure may activate a metal detector. Because of increased airport security measures, please call your local airport authority before traveling to get information that might help you pass through security more quickly and easily. Ask your physician to provide a patient identification card.
