Lateral sacrococcygeal ligaments

Lateral sacrococcygeal ligaments

The lateral sacrococcygeal ligaments are fibrous bands that connect the sacrum to the coccyx. These ligaments play a crucial role in stabilizing the pelvic region and supporting the vertebral column.

Anatomy

The lateral sacrococcygeal ligaments are part of the sacroiliac joint complex. They extend from the lateral margins of the sacrum to the coccyx, providing lateral stability to the sacrococcygeal joint. These ligaments are composed of dense connective tissue, which gives them the strength to withstand the mechanical stresses placed on the pelvis during activities such as walking, running, and sitting.

Function

The primary function of the lateral sacrococcygeal ligaments is to stabilize the sacrococcygeal joint. This joint is a cartilaginous joint that allows limited movement between the sacrum and the coccyx. The ligaments help to maintain the alignment of the vertebral column and prevent excessive movement that could lead to injury or discomfort.

Clinical Significance

Injuries to the lateral sacrococcygeal ligaments can occur due to trauma, such as falls or direct blows to the coccyx. These injuries can result in pain and instability in the pelvic region. Treatment may include rest, physical therapy, and in severe cases, surgical intervention.
