Sacroiliitis is not the same as SI joint dysfunction. Sacroiliitis is specific to an inflammatory processes present in the SI joint and the pain sensed is a direct result of those inflammatory processes, whereas sacroiliac joint dysfunction is a condition caused by abnormal motion or slight mispositioning of the SI joint.

Sacroiliac joint syndrome is a condition that is difficult to diagnose and is often overlooked by physicians and physiotherapist

Treatment of SI joint pain usually involves a multi-pronged approach, utilizing both, multi-modal medical pain control and interventional pain/surgical techniques such as local anesthetic and steroid injections, radiofrequency nerve ablation, and minimally invasive sacroiliac arthrodesis.[7] Sacroiliac (SI) joint injection is a minimally invasive procedure that involves injecting a mixture of local anesthetic and/or corticosteroid medication directly into the SI joint[8] Depending on the mixture of medications used, the duration of pain relief varies but can last anywhere from several days to months[9] Local anesthetic and corticosteroid medications are used to reduce inflammation and provide symptom relief to patients with arthritis, inflammatory conditions, and/or acute injuries[10]

The goal of SI joint injections is to provide enough pain relief to allow the patient to improve their functional status. Participation in physical therapy or exercise is encouraged, which can lead to longer-term improvements in pain and function. The number of SI joint injections required for effective pain relief can vary depending on the patient. [11, 12] Some patients may only require one injection, while others may require several injections. As a general guideline, injections may be administered once every 2 weeks, and no more than 3 injections may be given per year[11, 12] In general, if the first injection provides significant relief, additional injections may be recommended. However, the exact timing can vary based on the doctor's guidance, the patient's response to the treatment, and the type of injection[13] The long-term outcomes of SI joint injections can vary depending on a number of factors, including the underlying cause of the pain, the patient's overall health, the patient's response to the injection, and the type of injection used. Steroid injections may work well for some patients, while others may respond more positively to prolotherapy or PRP therapy[14]

Sacral Multifidus Plane Block(SMPB), a variant of paraspinal plane blocks, has been used for various surgeries in the perineal and buttock region[15]
