The sacrococcygeal joint is a special spot at the very bottom of your spine where the sacrum and the coccyx meet. It's like a tiny hinge that helps you sit down and stand up more comfortably.

Sacrococcygeal Joint

Bottom of your spine

The sacrum is a large, triangular bone at the base of the spine, formed by the fusion of five sacral vertebrae, and plays a crucial role in connecting the spine to the pelvis. It supports the weight of the upper body when sitting and standing, and forms the posterior part of the pelvic cavity, contributing to the stability and movement of the pelvis and lower limbs.

Sacrum

The coccyx, commonly known as the tailbone, is a small, triangular bony structure at the base of the vertebral column, composed of three to five fused vertebrae. It serves as an attachment site for various muscles, tendons, and ligaments, playing a crucial role in supporting pelvic functions and maintaining posture when sitting.
