Sacroiliac joint injections

What are Sacroiliac Joint Injections?

Sacroiliac (SI) joint injections are a minimally invasive treatment designed to relieve chronic lower back and hip pain caused by sacroiliac joint dysfunction, arthritis, or inflammation. The SI joints, located where the spine meets the pelvis, can become irritated due to injury, overuse, or degenerative changes, leading to persistent pain and mobility issues.

By delivering a targeted anti-inflammatory injection directly into the SI joint, this procedure helps reduce pain, improve mobility, and restore function—without the need for surgery.

Benefits of Sacroiliac Joint Injections

  • Provides rapid pain relief by reducing inflammation in the SI joint.
  • Minimally invasive with no downtime, allowing for a quick return to daily activities.
  • Improves mobility and function, helping patients stay active.
  • Can be used for diagnosis, confirming whether the SI joint is the pain source.
  • May prevent or delay the need for surgery, offering a non-surgical pain relief option.

Who is a Candidate?

Sacroiliac joint injections may be recommended for patients who:

  • Experience lower back, hip, or buttock pain that worsens with movement.
  • Have SI joint dysfunction, arthritis, or inflammation.
  • Struggle with pain when standing, sitting, or walking for long periods.
  • Have not found relief with physical therapy, medications, or other conservative treatments.

How the Procedure Works

SI joint injections are performed using fluoroscopic (X-ray) guidance for accuracy:

  1. A local anesthetic is applied to numb the injection site.
  2. A corticosteroid and anesthetic mixture is injected into the SI joint to reduce pain and inflammation.
  3. The procedure takes about 15-20 minutes, and patients can go home the same day.

Relief can be felt within a few days, with effects lasting weeks to months, depending on the severity of the condition.

Recovery Expectations

  • Minimal downtime, with most patients resuming normal activities within 24 hours.
  • Pain relief typically begins within 2-5 days, with maximum benefits in about a week.
  • Repeat injections may be needed, depending on symptom severity.
  • Physical therapy may be recommended to improve joint stability and prevent future issues.
