Sacroiliac joint steroid injections help doctors diagnose and relieve lower back pain caused by problems within the sacroiliac joint. This joint connects the base of the spine, called the sacrum, to the hip. If there is inflammation in one or both of the sacroiliac joints, also known as sacroiliac joint dysfunction, a patient may experience pain in the buttocks and lower back that worsens when running or standing for extended periods of time. This may be caused by trauma, injury, infection, pregnancy or other underlying conditions.
A sacroiliac joint steroid injection can be used to confirm a diagnosis of sacroiliac joint dysfunction. If the injection provides relief from painful symptoms, it will establish that this joint is the source of the pain. The sacroiliac joint steroid injection can also be used to treat this condition. The procedure involves carefully injecting steroids, along with a local anesthetic and saline solution, into the sacroiliac joint to reduce swelling and pain. This will often provide the patient with relief from symptoms for several months. As with other spinal blocks, if a sacroiliac joint injection successfully improves discomfort, it may be given up to three times per year.
It is important for patients to realize that spinal injections cannot cure their condition, but rather provide temporary relief from pain, inflammation and other symptoms. These treatments can be repeated if desired in order to prolong the results.
