Posterior (Open) Approach

Posterior (Open) Approach to the SI Joint

Lower back pain is commonly caused by one or both of sacroiliac (SI) joints. If non-operative treatment options fail to relieve SI joint related symptoms, a minimally invasive SI joint fusion may be considered. One method of performing this procedure is through a posterior (open) approach, or from the rear side of your body.

The Process of a Posterior (Open) Approach

The posterior approach provides access to three distinct areas including the posterior ilium, sacroiliac joint and posterior surface of the sacrum. Read on to learn more about how an SI joint fusion is performed using a posterior approach:

  • A small incision is made above the buttocks area, just below your waist. It may be slightly to the right or left of the spine, depending on which side requires treatment.
  • Using a series of specialized surgical tools, bone graft is implanted to encourage bone growth.
  • Sometimes, two devices will be implanted for extra stability and fusion.

Dr. Lewis is credited with being a pioneer of new implants and instruments for both the percutaneous and posterior SI joint fusion approaches. He frequently lectures at scientific meetings on the SI joint.

The Benefits of a Posterior (Open) Approach

There are several unique advantages to this type of surgical approach. For many years, it has been the preferred method for a variety of surgeries. This close approach provides a surgeon with the best possible view to allow optimum placement of surgical implants. Here are a few more benefits of a posterior approach:

  • Less invasive as fewer muscles are disrupted
  • Easier access to affected joint since the implant passes through less tissue
  • Provides better visibility
  • Fewer surgical steps to successful implantation
  • Limits adverse reactions to anesthesia
  • Reduces length of hospital stay

If you need to find a doctor who is experienced in performing SI joint fusion surgery, reach out to Dr. Lewis at Jackson Neurosurgery Clinic. With over 20 years of experience practicing, teaching and speaking to other members of the neuroscience community, he has perfected the most advanced spinal surgery techniques performed in the country. He has taught scores of other surgeons across the country, working with them in cadaveric laboratories and proctoring surgeons in live cases.
