Sacroiliac Joint Injection
A sacroiliac joint injection is a procedure in which a healthcare provider injects medication into the sacroiliac joint, which is located in the lower back where the sacrum (the triangular bone at the base of the spine) meets the ilium (the upper part of the hip bone). The sacroiliac joint is a weight-bearing joint that plays an important role in transferring forces between the upper body and the lower body.
The most common reason for a sacroiliac joint injection is to diagnose or treat sacroiliac joint dysfunction, which is a condition that can cause pain in the lower back, buttocks, and legs. Sacroiliac joint dysfunction can be caused by a variety of factors, including injury, arthritis, and pregnancy.
There are two types of sacroiliac joint injections: diagnostic and therapeutic. A diagnostic sacroiliac joint injection is used to identify the source of pain in the lower back and buttocks. It involves injecting a small amount of anesthetic into the sacroiliac joint and observing the patient for relief of pain. If the patient experiences significant pain relief after the injection, it can be concluded that the sacroiliac joint is a source of the pain.
A therapeutic sacroiliac joint injection is used to treat pain that is caused by sacroiliac joint dysfunction. It involves injecting a combination of anesthetic and corticosteroid into the sacroiliac joint. The anesthetic provides immediate pain relief, while the corticosteroid helps to reduce inflammation and improve mobility.
The procedure for a sacroiliac joint injection is usually performed in an outpatient setting, such as a doctor’s office or clinic. The patient lies on their stomach or side, and the healthcare provider cleans the skin and numbs the area with a local anesthetic. The provider then uses fluoroscopy (a type of x-ray) to guide a needle into the sacroiliac joint and inject the medication. The procedure usually takes about 30 minutes and the patient can usually return to their normal activities the same day.
There are some potential risks associated with a sacroiliac joint injection, including infection, bleeding, and nerve damage. However, these risks are rare and can usually be avoided with proper technique and sterile technique.
Overall, a sacroiliac joint injection can be an effective way to diagnose and treat sacroiliac joint dysfunction, helping to relieve pain and improve mobility. It is important to discuss the benefits and risks of the procedure with a healthcare provider to determine if it is the right treatment option for you.
