The traumatic SIJ injuries are caused by sudden impact which ‘jolts’ the joint, such as if you are thrown from a horse and land square on your buttocks. An injury of this nature can cause damage to the ligaments supporting the joint.
If the pain is due to biomedical causes, the injuries can take some time to manifest. They may show up during a period of increased activity or a change in sport or occupation. The most common biomedical causes include:
and muscle imbalances
Hormonal changes can also cause sacroiliac pain. Especially during pregnancy, hormonal changes which occur for the purpose of preparing the body to deliver a baby, the ligaments of the pelvis will increase in laxity. If this is combined with weight gain, the pressure put on the spine can lead to painful mechanical changes in this area.
Inflammatory Joint Disease
The most spine affecting inflammatory conditions are Spondyloarthropathis. These include Ankylosing Spondvlities which is the leading inflammatory condition to cause SI joint pain.
