An under diagnosed cause of low back pain could be due to the Sacroiliac joint (SI joint).
What is sacroiliac joint?
The SI joints are located between the iliac bones and the sacrum (in the pelvic region) and connects the spine to the hips. The SI joint functions as a shock absorber for the spine; it provides support and stability. It also transfers weight and forces between the upper body and legs. It is the largest joint in our body, and therefore at risk for injury.
What are the signs and symptoms of SI joint pain?
SI joint pain can present as low back pain and/or buttock pain. The pain can also be felt in the thighs, upper back and groin. The pain can involve one or both sides. It may be associated with numbness or tingling in the leg or a feeling of weakness in the leg. Symptoms may get worse with sitting, standing, sleeping, walking or climbing stairs. One can have pain when sitting or sleeping on the affected side. SI joint problem may make it difficult to ride in a car. Prolonged standing, sitting or walking can also be difficult. Transitional movements (going from sitting to standing), standing on one leg or climbing stairs may make the pain worse.
What causes SI joint pain?
There are various causes of SI joint pain:
How is the condition diagnosed?
A medical evaluation is necessary to diagnose this condition. A complete history and physical examination will be conducted. Physical examination will include testing the joints by doing specific maneuvers/tests which will manipulate the joints and also feel for tenderness over the SI joint.
Imaging studies which may include X-ray, CT scan, or MRI, may be ordered to help in the diagnosis and to make sure that the pain is not caused by other spine or hip related problems.
A diagnostic SI joint injection may be performed to confirm the cause of pain. The SI joint is injected with a local anesthetic and corticosteroid medication. This is done with x-ray guidance to ensure accurate needle placement in the SI joint. Sacroiliac joint involvement is confirmed if the injection significantly decreases the pain. If the procedure does not change the pain level, it is unlikely that the SI joint is the cause of the low back pain.
How is this treated?
Nonsurgical treatments may include physical therapy, chiropractic manipulation, and stretching exercises, oral anti-inflammatory medications or topical patches, creams, or mechanical bracing (SI joint belt).
SI joint injection: A mixture of anesthetic and corticosteroid is injected into the SI joint. If the injections are helpful, they can be repeated up to three times a year. Corticosteroids are not only effective but are typically covered by insurance carriers and have over 100 years of proven success.
Platelet rich plasma (PRP) injections have been shown to be effective in treating SI joint pain. This is newer technology but has been shown to be very effective when patients have failed to improve with corticosteroids.
Nerve ablations: Injections into joints or nerves are sometimes called “blocks.” Successful SI joint injections may indicate that the patient may benefit from radiofrequency ablation – a procedure that uses an electrical current to destroy the nerve fibers carrying pain signals in the joint.
Surgery: If nonsurgical treatments and joint injections do not provide pain relief, minimally invasive SI joint fusion surgery may be recommended. Through a small incision, the surgeon places titanium (metal) implants and bone graft material to stabilize the joint and promote bone growth. The surgery takes about an hour. The patient may go home the same day or the following day. For several weeks after surgery, the patient cannot bear full weight on the operated side and must use crutches for support.
