Sacroiliac Joint Dysfunction (Inflammation of the Sacroiliac Joint)

Inflammation of the Sacroiliac joint

Sacroiliac Dysfunction is deep aching pain or stiffness in the lumbar (lower back) region, usually on one side. Read on to discover possible causes for Sacroiliac Dysfunction, symptoms that sufferers may experience and Sacroiliac Join Dysfunction treatments.

Anatomy of the spine

Anatomy of the Spine

The sacroiliac joint at the base of the spine, formed between the sacrum and the ilium bones of the pelvis. It is a strong joint (due to the strong intrinsic and extrinsic ligaments) with limited movement. Humans have two sacroiliac joints, one on the left side of the sacrum and one on the right side.

Causes of Sacroiliac Joint Dysfunction

  • Damaged Cartilage – if cartilage is damaged or worn away, the bones will begin to rub against each other causing degenerative arthritis.
  • Pregnancy – ligaments relax as hormones are released into the body in order to prepare a woman’s body for child birth. This increases motion in the joints, which can lead to additional stresses and abnormal wear
  • Abnormal Walking pattern - any condition that alters the way a person walks, places additional stress on the SI joint EG: leg length discrepancy (one leg longer than the other), pain in the hip, knee, foot or ankle.

Sacroiliac Joint Dysfunction Symptoms

  • Deep aching and stiffness in the lower part of the lumbar region, usually on one side. These symptoms are most pronounced in the morning and after periods of inactivity.
  • The aching can radiate towards the buttock, back of the thigh or groin
  • Inflammation of the sacroiliac joint can, however, be painless
  • Tenderness over the joint lines on the back of the pelvis

Treatments for Sacroiliac Joint Dysfunction

Ice, heat and rest are all effective treatment options for suspected sacroiliac joint dysfunction. However, please consult with you medical professional for a complete diagnosis of your back pain and tailored back pain treatment plan. When the sacroiliac joint is hypermobile (or loose) it is often recommended to wear a brace or support to stabilise this area. Wearing a brace for sacroiliac joint dysfunction is particularly useful when the joint is inflamed and the individual is suffering acute pain.
