Supraspinous ligament

The Supraspinous Ligament is a strong fibrous cord, which connects the tips of the spinous processes from the seventh cervical vertebra to the sacrum, the midline dorsal aspect of the vertebral column.

Anatomy

The Supraspinous Ligament is a component of the vertebral column, which is a complex structure that supports the body and protects the spinal cord. The ligament is located on the posterior side of the vertebral column, running along the tips of the spinous processes. It is thicker and broader in the lumbar than in the thoracic region, and intimately blended with the ligamentum flavum and the posterior longitudinal ligament.

Function

The primary function of the Supraspinous Ligament is to limit the movement of the vertebral column, particularly flexion. It also serves to protect the vertebrae and discs from injury.

Clinical Significance

Damage or injury to the Supraspinous Ligament can result in back pain and limited mobility. It can be caused by trauma, such as a fall or car accident, or by degenerative conditions like osteoarthritis. Treatment typically involves physical therapy, pain management, and in severe cases, surgery.

Etymology

The term "Supraspinous" is derived from the Latin words "supra," meaning above, and "spina," meaning spine. Thus, "Supraspinous" refers to the location of the ligament above the spinous processes of the vertebrae.
