Anterior sacrococcygeal ligament

Anterior view of the sacrum and coccyx, showing the anterior sacrococcygeal ligament (in red).

The Anterior Sacrococcygeal Ligament is a fibrous tissue that connects the sacrum and the coccyx, two bones at the base of the vertebral column. This ligament is part of the human body's complex system of connective tissues that provide support and stability to the skeletal structure.

Anatomy

The anterior sacrococcygeal ligament is a continuation of the anterior longitudinal ligament that runs down the front of the vertebral bodies. It is thinner and less robust than its posterior counterpart, the posterior sacrococcygeal ligament. The ligament is attached above to the anterior surface of the sacrum, and below to the front of the coccyx.

Function

The primary function of the anterior sacrococcygeal ligament is to maintain the alignment of the sacrum and coccyx, thereby contributing to the stability of the pelvis. It also limits excessive movement between these two bones, preventing potential injury.

Clinical Significance

Damage or degeneration of the anterior sacrococcygeal ligament can lead to instability or hypermobility of the coccyx, a condition known as coccydynia. This can cause significant pain, particularly when sitting or moving from a sitting to standing position.
