Sacroiliac Joint Pain

Sacroiliac pain is a type of lower back pain that occurs at the SI joint, which connects the spine to the pelvis. The pain can range from mild to severe and is more often than not worse while sitting.

The sacroiliac joints (SI joints) are located between the sacrum, which is the triangular shaped bone at the bottom of the spine, and the iliac bones on either side of the pelvis. The joints are held together by strong ligaments and support the entire weight of the upper body when standing erect which places large amount of stress across them.
Sacroiliac joint pain can be caused by sprain/strain injury ( common), wear and tear of the joints, or very occasionally a forms of arthritis that cause inflammation, restrictions, and pain.

Conditions that affect the normal walking patterns, such as a leg length differences, or pain in the hip, knee or foot will also place increased stress on the sacroiliac joints and can result in strains or accelerated wear and tear of the joints. Another common cause of SI pain is pregnancy as the hormone relaxin is released to allow the ligaments to stretch in preparation for childbirth. This can cause increased movement in the joints which can cause increased stress and abnormal wear and tear. Sacroiliac joint pain during pregnancy is referred to as pelvic girdle pain ( see separate post on pelvic girdle pain ).

When you visit a chiropractor for sacroiliac joint pain we will likely perform an adjustment or manipulation of your SI joint(s.) This involves applying gentle pressure to the affected area in order to restore proper alignment in the spine, reduce inflammation, and improve mobility in the joint. We also use soft tissue techniques to relieve any associated muscular tensions.
