The sacroiliac joints have small amount of movement and transmits all the forces of the upper body to the lower body. The sacrum is the triangular-shaped bone at the bottom of the spine, below the lumbar spine. The sacroiliac joint acts as a shock-absorbing structure. Sacroiliac joint dysfunction or Sacroiliac joint pain is one of the common causes of the low back pain.
