Sacroiliac Joint Dysfunction

What is Sacroiliac Joint Dysfunction?

Sacroiliac (SI) joint dysfunction refers to pain and discomfort originating from the sacroiliac joint, located where the lower spine meets the pelvis.

This joint plays a crucial role in supporting the weight of the upper body and ensuring proper alignment and movement between the spine and pelvis.

When this joint becomes inflamed, irritated, or moves improperly, it can lead to pain in the lower back, buttocks, and legs, a condition commonly referred to as SI joint dysfunction.

Causes of Sacroiliac Joint Dysfunction

Several factors can contribute to the development of SI joint dysfunction, including:

  • Trauma or injury: A sudden impact, such as a car accident or a fall, can damage the SI joint and cause dysfunction.
  • Pregnancy: During pregnancy, the body releases hormones that allow the ligaments in the pelvic area to relax, which can affect the SI joint’s stability.
  • Arthritis: Degenerative conditions like osteoarthritis can wear down the cartilage in the SI joint, leading to pain and dysfunction.
  • Abnormal movement patterns: Repetitive motion or uneven leg length can cause the SI joint to become misaligned, leading to inflammation and pain.
  • Previous surgeries: Certain back surgeries can alter the biomechanics of the spine and pelvis, increasing the risk of SI joint dysfunction.

Symptoms of Sacroiliac Joint Dysfunction

The most common symptoms of SI joint dysfunction include:

  • Lower back pain: Often felt on one side of the body and can radiate to the hips, buttocks, or thighs.
  • Pain while standing or sitting: Sitting for long periods or standing on one leg may aggravate the discomfort.
  • Stiffness or reduced range of motion: A feeling of stiffness in the lower back or difficulty performing movements like bending or twisting.
  • Instability: Some patients may feel as though their pelvis is unstable or their legs may give way.

Treatment for Sacroiliac Joint Dysfunction

There are various treatment options available for SI joint dysfunction, depending on the severity and underlying cause of the condition. Talk to your doctor to find the best treatment plan for you. Treatment options include:

  • Physical Therapy: Exercises aimed at improving joint stability and strengthening the muscles around the SI joint can help alleviate pain.
  • Medications: Anti-inflammatory medications, muscle relaxers, or corticosteroid injections may be prescribed to reduce inflammation and manage pain.
  • Joint Injections: Steroid or anesthetic injections can provide temporary relief by reducing inflammation and numbing the joint.
  • Chiropractic Care: Manual adjustments or manipulations may help restore normal motion to the SI joint.
  • Surgery: In severe cases where conservative treatments are not effective, SI joint fusion surgery may be recommended to stabilize the joint and relieve pain.
