Sacroiliac Pain

The sacroiliac joint is the joint that connects the spine to the pelvis. This is one of the most unique joints in the human body because it has a limited range of motion of less than 20 degrees. The sacroiliac joint also happens to be one of the few bicondylar joints with two surfaces that move and work together to produce motion. The limited range of motion and the bicondylar nature of the joint makes it incredibly hard to dislocate.

When the two surfaces of the sacroiliac joint don’t work together, you experience sacroiliac pain. Consequently, the sacroiliac joint disorder is marked by the dysfunction and loss of mobility in the sacroiliac joint, leading to pain in the lower back and legs. The symptoms are usually dull, but they can intensify over time, leading to increased difficulty while running or climbing the stairs. The root cause of sacroiliac joint pain isn’t well known.
