Sacroiliac Joint Injections

Sacroiliac injections, also known as SI joint injections, are a type of medical procedure used to diagnose and treat pain in the sacroiliac joint. The sacroiliac joint is located in the lower back and connects the sacrum (the triangular bone at the base of the spine) to the pelvis. This joint plays a crucial role in supporting the upper body and transferring forces from the spine to the lower body during activities such as walking, running, and bending.

During a sacroiliac injection, a healthcare provider injects a local anesthetic and often a corticosteroid medication directly into the sacroiliac joint. The purpose of this injection is twofold:

  1. Diagnosis: The injection helps determine whether the sacroiliac joint is the source of a patient's pain. If the injection provides significant pain relief, it suggests that the sacroiliac joint is indeed the cause of the pain.

  2. Treatment: In addition to diagnosing the source of pain, sacroiliac injections can also provide therapeutic benefits by reducing inflammation and alleviating pain in the sacroiliac joint region. This can improve the patient's overall mobility and quality of life.

Sacroiliac injections are commonly used to treat conditions such as sacroiliac joint dysfunction, sacroiliitis (inflammation of the sacroiliac joint), and related lower back pain that originates from the sacroiliac joint. These injections are often part of a comprehensive treatment plan that may include physical therapy, medications, and lifestyle modifications to manage and alleviate symptoms associated with sacroiliac joint disorders.
