The pelvic joint refers to the area where the pelvis connects to the spine and the lower limbs. It consists of several key structures, including the sacroiliac joints, which link the sacrum to the ilium bones of the pelvis. This joint plays a crucial role in supporting the weight of the upper body and facilitating movement during activities like walking and running. Additionally, the pubic symphysis is another important component of the pelvic joint, located at the front of the pelvis. It is a cartilaginous joint that allows for slight movement, providing flexibility during childbirth and other physical activities. Overall, the pelvic joint is essential for stability and mobility in the human body.
