Supraspinous fascia

Diagram of the supraspinous fascia and surrounding structures.

The supraspinous fascia is a connective tissue structure located in the back, specifically in the region of the thoracic vertebrae. It is part of the complex network of fasciae that support and stabilize the musculoskeletal system.

Anatomy

The supraspinous fascia is situated above the spinous processes of the thoracic vertebrae. It extends from the nuchal ligament in the neck down to the sacrum in the lower back. This fascia is continuous with the thoracolumbar fascia and plays a crucial role in the structural integrity of the back.

Function

The primary function of the supraspinous fascia is to provide support and stability to the vertebral column. It acts as a tension band that helps maintain the alignment of the vertebrae during movement. Additionally, it serves as an attachment point for various muscles, including the trapezius and latissimus dorsi, which are involved in the movement of the shoulders and arms.

Clinical Significance

Injuries or dysfunctions of the supraspinous fascia can lead to back pain and reduced mobility. Conditions such as fasciitis or myofascial pain syndrome may involve the supraspinous fascia, requiring interventions such as physical therapy or manual manipulation to alleviate symptoms.
