Coccyx

The coccyx, also known as the tailbone, is a small triangular bone located at the bottom of the spine. It is made up of three to five vertebrae that are fused together, and it is the lowest part of the spine.^[6]

Structure

The coccyx is a small bone that is located at the bottom of the spine, between the sacrum and the pelvis.^[4] It is made up of three to five vertebrae that are fused together. The coccyx is a triangular bone, with a pointed end and two flat sides. It is surrounded by muscles, tendons, and ligaments, which help to support and stabilize it.^[5]

Location

The coccyx is located at the bottom of the spine, between the sacrum and the pelvis. It is located in the lower part of the back, just above the buttocks.^[2] The coccyx is not visible from the outside of the body, as it is covered by skin, muscle, and other tissues.

Function

The coccyx serves several important functions in the body. It helps to support the weight of the upper body and provides a point of attachment for several muscles and ligaments.^[8] It also helps to balance the body and maintain proper posture.^[7]

Clinical Significance

There are several clinical conditions that can affect the coccyx. One common condition is coccydynia, which is pain in the coccyx.^[1] This condition can be caused by a number of factors, including trauma, infection, and inflammation. Other conditions that can affect the coccyx include osteoarthritis, degenerative disc disease, and spinal stenosis. Treatment for coccydynia and other conditions affecting the coccyx may include physical therapy, medication, and, in some cases, surgery.^[3] It is important to seek medical attention if you are experiencing pain or discomfort in the coccyx area, as prompt treatment can help to alleviate symptoms and prevent further damage.
