If you’ve been living with back pain then you know the impact it can have on your life. VTI offers advancements that can help ease your pain and get you back to living. The following patient information is intended to help you understand the anatomy of the spine and the best treatment option for you. This information should not replace your doctors opinions or recommendation of treatment. Consult with your surgeon and/or your primary doctor with any questions or concerns before deciding the best solution for your back pain.



The spine is a complex structure of bones and joints surrounded by muscles supported by soft tissues. The lower back, also known as the lumbar spine, sustains the weight for the spine. All movements of the body are supported by the lumbar spine. In the spine, there is a vertebra and a disc that cushions impact. This allows for movement that maintains separation between other vertebraes. Each disc has an outer ring, called the annulus fibrosis, which is made of fibers to keep the disc intact. The inner portion of the disc is called the nucleus pulposus or the nucleus. It consists mostly of water and provides cushion needed to absorb the forces exerted on the spine during bodily movement.


The vertebra in the spine has letters and numbers that refers to its location. If the vertebra is in the lumbar region of the spine, it has an L and a number that corresponds to its position within the lumbar spine. The numbers begin with 1 (at the top of the lumbar spine) and end with 5 (at the base of the lumbar spine). The bones of the sacrum, have a similar numbering system: S1-S5. The diagram to the side illustrates the lumbar spine and the sacrum. VTI’s InterFuse® system performs best when used treating the L5/S1 region, but is not limited to that region. Maybe: VTI's InterFuse system is offers advantages at L4/L5 and L5/S1 levels, but is not limited to use at these levels.(Insert citation to FDA indication).


There are a number of methods to treat lower back pain, including surgical and non-surgical techniques. Your surgeon will work with you to determine the source of your pain and recommend the most appropriate method of treatment for you the patient. Non-surgical treatments include weight loss, exercise, medications, injections or physical therapy. While non-surgical treatments may result in improvement for some patients, others may not improve. In these cases, surgical treatment may be recommended by your physician. The most common surgical treatment is spinal fusion. It is used to restore lost disc height, remove pressure from nerves and stabilize the spine. After removing the diseased disc, a surgical implant containing bone graft material is placed between two adjacent vertebrae’s. The bone graft inside the implant is intended to stimulate bone growth in the disc space, joining the two vertebrae’s together.

WHAT IS Minimally invasive spine surgery (MISS)

Minimally Invasive Spine Surgery (MISS) is sometimes referred as less invasive spine surgery. In a MIS procedure, surgeons will use specialized surgical instruments to access the spine through a small tube and access through a small incision. In a traditional, open spine surgery, the surgeon will make a large incision and retracts, or pulls, the muscles to the side to get a clear view of the spine. With MIS spine surgery, surgeons can achieve the same effective goals as an open procedure, but in a less invasive way.


The InterFuse® System is a unique proprietary intra-operative assembly technology from VTI, which allows surgeons to implant a large footprint device through a minimally invasive approach. The shape of each device is biomechanically optimized to match the contours of the vertebrae and the unique anatomical shape and size of each patient’s disc space. The result is a less invasive implantation that achieves an astounding 97% fusion rate (*see 6 month fusion outcome document in resource library*). The result is a less invasive device implantation without the compromises typically associated with MIS implants.
