Why does the sacroiliac joint start having problems?
If the motion in your pelvis is asymmetric, then dysfunction can occur in your sacroiliac joint. You could have asymmetric motion if your legs are significantly different in length. This can be congenital or caused due to an injury or illness such as polio or scoliosis. Other conditions that can predispose you to sacroiliac joint dysfunction include having one leg that is weaker, such as seen with hip osteoarthritis. These biomechanical conditions, or even wearing inappropriate footwear, can alter your gait and cause repetitive stress to your sacroiliac joint and related structures. Other potential causes of Sacroiliac (SI) Joint problems include degenerative disease, history of trauma, pregnancy/childbirth, and other unknown reasons.
