SI (sacroiliac) joints support the weight of the human body, distributing it across the pelvis. This acts as a shock absorber and reduces pressure on the spine.
This week, we delve into one of the most common lower back pain complaints – SI joint pain. There are many causes of this condition but fortunately, there are also solid treatment options.
SI joints are located at the crux of the sacrum and ilium of the human body. The sacrum is located just above the coccyx, or tailbone. It is a triangle-shaped bone near the bottom of the spine. The ilium is one of the three bones that make up the hip bones. It is located at the uppermost point of the pelvis.
SI joints are composed of bones with jagged edges. These jagged edges help them stay in alignment. Spaces between the bones of the SI joints are filled with fluid, which provides lubrication. These spaces are also filled with free nerve endings, which send pain signals to the brain. When the bones in the SI joint become out of alignment, it can be painful.
All of the bones in the SI joints are connected by muscles and extra-strong ligaments, which add stability and allow for limited movement. Though minimal, this movement is necessary for you to remain upright and for women to give birth.
Inflammation of one or both SI joints is called sacroiliac joint dysfunction, or sacroiliitis. This is a general term that encompasses a number of conditions, including the following:
Although AS primarily affects SI joints, it can also cause inflammation in other joints and, more rarely, organs and eyes. AS is a chronic disease. It may cause intermittent episodes of mild pain, or more severe ongoing pain. This disease is diagnosed most frequently in young men.
Some women may walk abnormally while they’re pregnant. Once they give birth and resume walking normally, their SI joint pain may go away.
Next time, we will discuss the symptoms and methods of diagnosing SI joint pain.
