A Sacroiliac joint injection, more commonly referred to as a SI joint injection, is an injection to treat Sacroiliac Joint Dysfunction.
During the procedure, the patient lies on their stomach with a pillow placed under the stomach for comfort. The physician uses a live X-Ray machine called a fluoroscope to locate the SI joint. A small amount of local anesthetic is used to numb the skin to keep the patient comfortable throughout the procedure. With the guidance of the fluoroscope, the physician carefully guides the needle to the SI joint, where the spine and hip joint meet.
SI Joint injections can be performed with steroids, Platelet Rich Plasma (PRP), or Bone Marrow Concentrate. Prolotherapy has also been shown to be effective with SI Joint Dysfunction.
