Sacroiliac Joint Injections: A Patient’s Guide
Overview
Sacroiliac joint injections are a common procedure used to help diagnose and treat pain in the sacroiliac joint, which is located in the lower back and connects the sacrum (the triangular bone at the base of the spine) to the ilium (the pelvic bone). This condition affects many individuals, with an estimated 15-30% of chronic lower back pain cases attributed to issues with the sacroiliac joint.
Types
There are two main types of sacroiliac joint injections: diagnostic and therapeutic. Diagnostic injections are used to help identify the specific source of pain, while therapeutic injections are intended to alleviate pain and inflammation in the joint.

The exact causes of sacroiliac joint pain can vary, but common factors include:
- Trauma or injury to the joint
- Arthritis
- Pregnancy-related changes
- Inflammation
- Degenerative joint disease
Symptoms
Symptoms of sacroiliac joint pain can include:
- Lower back pain
- Hip pain

Diagnosis
Diagnosing sacroiliac joint pain typically involves a combination of physical exams, imaging studies (such as X-rays or MRI scans), and diagnostic injections to confirm the source of the pain.
