Your Healthy Spine

To understand a spinal condition, it is helpful to first understand some basics about the spine.

The Sacrum and Coccyx

The sacrum and coccyx are part of the vertebral spinal column; the anatomy of the sacral spine and tailbone is explained.

Lumbar Spine, Sacrum, and Coccyx

Find out how the lumbar spine is made for walking, running, sitting, and lifting. Furthermore, gain a better understanding of lordosis and why sitting may increase coccyx pain.

Sacroiliac Joint is Different from Other Joints

Every time you walk, the sacroiliac joints distribute the shock of motion across the pelvis, thereby reducing strain on the spine. The SI joints help stabilize the body, enabling you to maintain an upright position while walking or running.

Spinal Discs Connect and Protect Vertebrae

The spine's discs sit between each vertebra. They are tough on the outside with a softer, gel-like fluid inside. Each time you move the spine, the discs change shape in relation to the movement.

Vertebral Column: Backbone of the Spine

The spinal column, better known as your backbone, is a strong yet flexible multipurpose structure. It is designed to protect the spinal cord, absorb and distribute shock, while supporting the weight of your head and torso and allows you to move in many directions.
