The sacroiliac joints are located below the lumbar spine and above the tailbone, connecting the sacrum, which is triangular bone at the bottom of the spine, to the iliac crest, also known as the pelvis. There are two sacroiliac joints that connect to either side of the pelvis, and serve to support weight from the upper body and distribute it evenly to the lower body. The ligaments of the sacroiliac joints are among the strongest in the body and as a result, the flexibility they enable is limited.
Sacroiliac joint disorder describes pain and inflammation of the sacroiliac joints, which can be a result of too much or too little motion (hypermobility and hypomobility), degeneration caused by osteoarthritis, or any condition that affects normal walking ability. Depending on the source of sacroiliac joint dysfunction, it can cause pain in slightly different locations, including the lower back, hip, buttocks, groin, and/or leg.
Cortisone is used by Genesis Orthopedics & Sports Medicine to determine that the sacroiliac joints are in fact the source of pain, while simultaneously relieving inflammation and pain.
By strengthening the muscles supporting the spine, physical therapy can minimize the pressure placed on the sacroiliac joint. Physical therapy is typically recommended by Genesis Orthopedics & Sports Medicine for the treatment of most types of back pain, which includes that localized to the sacroiliac joints.
