Sacroiliac Joint Injections
Sacroiliac Joint Injections for Lower Back & Pelvic Pain
Sacroiliac (SI) Joint Steroid Injections help reduce inflammation and pain in the joint that connects the spine to the pelvis. When this joint becomes irritated, it can cause discomfort in the lower back, hips, or buttocks, especially during movement. At iMsk & Spine Group, these injections are performed using precise image guidance to ensure safe placement and effective results.
What Is a Sacroiliac Joint Steroid Injection?
An SI joint injection delivers anti-inflammatory medication directly into the sacroiliac joint space. This reduces swelling and irritation around the joint, helping to relieve persistent lower back or pelvic pain. The injection may also be used to confirm whether pain is coming from the SI joint.
Why It Helps
Inflammation inside the SI joint can create deep aching pain or instability during walking, bending, or standing. Targeted injections help calm inflammation, improve comfort, and often reduce the need for stronger medication or more invasive procedures.
Conditions It Helps Treat
Sacroiliac Joint Injections may be recommended for:
- Sacroiliitis
- Lower back pain
- Hip or buttock pain
- Pelvic pain
- Joint inflammation
How Treatment Works
The procedure is typically completed in-office under imaging for accuracy.
A typical session includes:
- Local numbing
- Image-guided injection
- Brief monitoring period
- Return home the same day
Many patients notice relief within a short time, depending on the level of inflammation.
