What is the degree of the SI joint?
1-3 degrees
The degree of the SI joint refers to the range of motion or the amount of movement that occurs at the sacroiliac joint. The sacroiliac joint is located between the sacrum (a triangular bone located at the base of the spine) and the ilium (the large, fan-shaped bone that makes up the upper part of the pelvis). It is an important joint that transfers loads from the trunk to the lower extremities during weight-bearing activities such as walking, running, and jumping.
The degree of motion of the SI joint is generally small but varies between individuals. In a healthy adult, the SI joint can move up to 2-4 millimeters during normal daily activities. However, this range of motion can be affected by various factors such as age, gender, prior injury or surgery, pregnancy, and other underlying medical conditions. It is important to note that excessive or limited movement of the SI joint can result in pain, instability, and dysfunction, which may require medical intervention.
