What Is the Coccyx?
The coccyx is the small, triangular bone at the bottom of the spine, commonly called the tailbone. It connects with the sacrum and helps support the pelvis while you sit. Muscles, ligaments, and connective tissues attach around it, so irritation in this area can affect nearby pelvic and lower back movement.

Key Takeaways About Coccyx
- The coccyx sits below the sacrum at the base of the spine.
- Its surrounding tissues help manage sitting and pelvic movement.
- The coccyx is not the same bone as the sacrum.
How Coccyx Works
Coccyx refers to the lowest bone in the spinal column. Its position below the sacrum allows it to work with the pelvis during sitting, standing, and changes in posture. Several muscles and ligaments connect near the coccyx, so movement in the area depends on more than the bone alone.

Chiropractic adjustments assess the coccyx in relation to the sacrum, pelvis, and lower spine. A practitioner may consider tenderness, alignment, joint motion, and the way nearby tissues respond during movement. The coccyx has limited motion, so evaluation focuses on its surrounding structures and its relationship to the rest of the pelvic region.
From the Arrowhead Clinic Chiropractor Hinesville team
When we assess the coccyx, we consider the lower spine, sacrum, pelvis, and nearby soft tissues together. Our team checks movement and tenderness through a focused examination before deciding whether a chiropractic adjustment fits the person’s presentation. This approach helps separate coccyx-related findings from broader lower back or pelvic concerns.
Coccyx in Practice: A Real-World Example
A person who feels discomfort after sitting may have tenderness around the coccyx and reduced movement in nearby pelvic structures. During Chiropractic Adjustments, we assess the coccyx area alongside the sacrum and lower spine to guide the examination.
