the symptoms


Although it may be difficult for you to identify the exact cause of your pain, your doctor can perform simple tests to help determine the source of your low back problems. Some common symptoms of SI Joint Dysfunction include:

Pain in your buttock.
This pain is usually a dull ache on one side of your lower back and may extend into the thigh.

Pain and discomfort performing daily activities.
These activities may include walking up and down stairs, climbing hills, vacuuming and other activities that require your pelvis to twist.

Pain may increase with prolonged sitting, weight bearing on the painful side or bending forward with knees extended.1

Difficulty sitting or lying down.
This is often experienced as an ache on one side that causes you to sit on one buttock to relieve the pain in the other side.


Trouble keeping your seat?
The sacroiliac joint is the cause of low back pain in three of every 10 patients with previous lumbar fusion.3

Want to sit back, relax?

If you’ve tried conservative therapies—like anti-inflammatory or pain medications, braces, chiropractic treatment, physical therapy or sacroiliac joint injections—for at least six months without lasting relief, your doctor may recommend minimally invasive SI joint fusion surgery as the next step.
