Significance of Sacroiliac joint
The sacroiliac joint refers to the joints located between the sacrum and the iliac bones of the pelvis. These joints are commonly affected by ankylosing spondylitis, leading to pain and stiffness. As a weight-bearing synovial joint, it connects the hip bone with the sacrum at the base of the spinal column and is characterized by limited movement and stabilizing ligaments. Additionally, during pregnancy, these joints may be influenced by hormonal changes causing pelvic girdle pain.
