One of the most common causes of low back and pelvic pain occurs with injuries to the sacroiliac (SI) joint and ligaments.
SI Joint Dysfunction Facts & Information
If you are experiencing the seemingly unbearable symptoms of SI joint dysfunction, it’s important to have an accurate diagnosis with thorough tests and evaluations. Often times, sacroiliac (SI) joint dysfunction is difficult to diagnose because the pain patterns are frequently mistaken for nerve irritation in the lower back, muscles sprains, or hip bursitis.
How & Why Does SI Joint Dysfunction Develop?
First, it’s key to understand that the SI joint connects the pelvic bone (ileum) to the lowest part of the spine (sacrum). There are two SI joints. Each is located on either side of the sacrum. SI joints are small and very strong, providing structural support and stability. They function as shock absorbers for the pelvis and the low back, dispersing the forces of the upper body. Whenever an SI joint is irritated or injured, the resultant joint dysfunction may cause pain in the lower back and legs.
SI joints become painful because of alterations in the normal motion of the joints. Consider the following:
► Two types of changes from normal motion can cause problems
► Those changes are either too much movement (hyper-mobility) or too little movement (hypo-mobility)
► Abnormal motion from work/sports can directly injure the joints via stretching/straining the primary SI ligaments
► Any of these changes in joint mobility may lead to pain, as well as spasm in the supporting back and pelvic muscles
► SI joint dysfunction may also result from direct trauma, such as injuries associated with a motor vehicle accident
► Or an injury from something as simple as a fall on the buttocks or a missed step when descending stairs
