Sacroiliac Joint Fusion

The sacroiliac joint is in your pelvic region. It can be a common source of low back and buttocks pain, and causes a condition called Sacroiliitis. This condition describes pain emanating from the sacroiliac joint near the base of the spine and is extremely common in women. Sacroiliac joints must loosen and stretch to accommodate childbirth and weight gain, and an altered gait during pregnancy can increase stress which can result in pain and/or dysfunction that causes Sacroiliitis.


Most patients have difficulty sitting, low back pain, and cannot cross their legs in a “figure four” position. The patient’s ability to climb stairs, run or take longer strides may also be prohibited due to sacroiliac pain and stiffness. When these symptoms are too much to bear and are hindering daily life and overall quality of life, a minimally invasive fusion may be the most effective solution to permanently eliminating the pain.

How Sacroiliac Joint Fusion works

Dr. Scott Katzman has promulgated a minimally invasive technique for sacroiliac joint fusion using the S.I. Fix Implant, and is a world-renowned orthopedic surgeon. Since the sacroiliac joint naturally has extremely limited motion, Dr. Katzman’s minimally invasive technique eliminates the source of pain by fusing it without traditional, invasive fusion surgery to preserve as much range of motion as possible.

What is an S.I. Fix Implant?

Dr. Katzman has performed so many successful sacroiliac joint fusions that he was able to develop a new device that provides a permanent fix for sacroiliac joint pain. The S.I. Fix Implant, an S.I. (sacroiliac) joint implant, is used for this fusion surgery and was invented and developed primarily through Dr. Katzman’s guidance. A direct fusion is accomplished through a “mini open technique” which allows for the accurate placement of the bone screw fixation device with a smaller incision and reduced blood loss. Its unique insertion is safer than and equally effective as other methods of fusion, and results in a reduced and less painful recovery period.

What are the advantages of sacroiliac joint fusion?

Our team of spine surgeons perform this surgery on an outpatient basis and boast over a 98% success rate.

Sacroiliac joint fusion surgery takes only one hour on average to perform, whereas traditional fusion surgery typically takes several hours. Sacroiliac joint fusion also requires only one night in the hospital, whereas traditional, outdated fusion surgery methods force the patient to remain in the hospital for several days following the procedure.

If you or someone you love is suffering from the symptoms caused by sacroiliac joint pain, sacroiliac joint fusion may be your best option for treatment. Try our free Treatment Check tool below to begin seeking the best solution to your pain.


The best method for diagnosing sacroiliitis is to perform a sacroiliac joint block. An injection of lidocaine or marcaine (bupivacaine hydrochloride and epinephrine) into the joint should cause temporary pain relief. If this occurs, the diagnosis of sacroiliitis is almost certain.

Conservative treatment approach

Conservative treatments can then start to fix your pain. Typically, a series of cortisone injections will be prescribed and these may provide lasting relief. Other non-surgical options for treating sacral pain may include:

  • Medications
  • Support braces
  • Physical therapy

More invasive treatments for sacroiliac pain

In some cases, therapy, stretching and exercise may strengthen muscles in the lower back and restore enough flexibility to relieve the patient’s discomfort. If not, slightly more invasive treatments may include:

  • Radiofrequency ablation
  • Laser treatment
  • Electrotherapy
  • S.I. joint implant via fusion

A shorter, less painful recovery with NJSO

Our surgeons are very experienced with treating sacroiliac joint pain with conservative methods, and view surgery as the last option to achieving relief. In fact, we are usually able to make the pain and dysfunction go away.

Unfortunately, when the sacroiliac joint pain becomes unbearable and causes difficulty in performing simple daily activities, surgery may be required. The best surgical method is a direct fusion of the sacroiliac joint, which is typically accomplished as an outpatient procedure using Dr. Katzman’s minimally invasive technique and the S.I. Fix Implant.
