Some treatments for sacroiliitis include medications such as pain relievers, tumor necrosis factor inhibitors and muscle relaxants, Mayo Clinic states. More invasive treatments include corticosteroid injections into affected joints, joint fusion, implantation of an electrical stimulator and destruction of the affected nerves with radio frequency radiation.
Sacroiliitis is a condition in which the sacroiliac joints, at the junction between the pelvis and the spinal column, are inflamed, explains Mayo Clinic. This condition causes pain in the lower back and buttocks, which can extend all the way to the feet. The pain caused by sacroiliitis is often worsened by stair climbing, running, unequal weight distributions, prolonged standing or taking long strides. Causes of this condition include osteoarthritis, trauma, pregnancy and infections of the joints. Sacroiliitis can also arise as a complication of an inflammatory condition known as ankylosing spondylitis, and it is in this case that tumor necrosis factor inhibitors are useful.
Sacroiliitis is often difficult to diagnose, since several other conditions can produce similar symptoms, Mayo Clinic says. Doctors use pressure on specific points to find the site of inflammation, along with movement and position tests to check for telltale sensitivity. Imaging tests such as X-rays and MRI are often used for a final confirmation of the diagnosis.
