Dysfunction of the sacroiliac joint causes SI joint pain usually in the lower back, and sometimes this is also accompanied by leg pain. The leg pain can be difficult to differentiate as it can also be caused due to sciatica pain which is a form of neuropathic pain and their feelings can be remarkably similar. SI joint dysfunction has been identified as the main cause in 15% to 30% of lower back pain cases. Read on to know more about the pain due to sacroiliac joint dysfunction.

What Is The Sacroiliac Joint?

The sacroiliac joint also known as the SI joint connects the hip bone to the sacrum, and its main function is shock absorption between the upper body, legs, and pelvis. It is surrounded by strong ligaments, and they reinforce it. Besides, this joint has limited movement compared to other joints in the body because it moves only in the forward and backward directions for absorbing shock. Also, the network of soft tissues around the SI joint helps with absorbing pressure and limits its movements.

What Are The Causes For Sacroiliac Joint Pain?

Sacroiliac joint pain is caused due to the dysfunction of this joint, and the primary reasons for it are shared below.

  • Too much movement or instability of the sacroiliac joint makes the pelvis unstable, and this leads to pain. This pain is usually experienced in the lower back, hip, and may extend to the groin region.
  • Too little movement or fixation of the sacroiliac joint causes pain, muscle tension, and thereby reduces mobility. The pain due to this is experienced in the buttocks, side of the lower back, and may extend to the back of the leg like sciatica pain.

Sacroiliitis or the inflammation of the sacroiliac joint also causes pain in the pelvis along with stiffness. This can also happen due to sacroiliac joint dysfunction, rheumatoid condition, and infection.

Diagnosis For Sacroiliac Joint Dysfunction?

Multiple test results are combined to diagnose sacroiliac joint dysfunction. This is because its symptoms mimic other disorders like sciatica. The diagnosis begins with analyzing medical history and past test results, along with the information on current symptoms. Physicians also consider factors like duration of sleep, diet, habits, daily activities like exercise, past injuries, etc. Listed below are the orthopedic tests to identify this condition.

  • Sacral thrust test
