Sacroiliac joint injections are used to treat and provide diagnostic confirmation of Sacroiliac joint pain. Sacroiliitis is pain and inflammation associated with the Sacroiliac joint, which is the major joint connecting the spine to the pelvis. It is a relatively common cause of low back and buttock pain that may be aggravated by walking, running and sitting for long periods. Sacroiliitis may be caused by inflammation, arthritis or previous injury and pain may persist for long periods of time in some cases.
The Sacroiliac joints are important for shock absorption at the base of the spine and for stability during walking and running. Sacroiliitis may go undiagnosed and untreated for long periods of time, but may respond well to targeted injections. Relieving the pain by injecting the Sacroiliac joint with local anaesthetic can confirm the diagnosis of Sacroiliitis, thus enabling more definitive treatment if required and also avoiding further unnecessary investigations and surgery.
The procedure is performed in outpatient theatre and there is no need for an overnight stay. Fluoroscopic (X- ray) guidance is used to ensure safety and accuracy. Patients can walk in and out within a few hours ensuring minimal time away from work and home. Physical therapy will then usually be recommended to help the patient rehabilitate and strengthen the muscles around the spine
