Supraspinous fascia

Supraspinous Fascia is a layer of fascia that covers the supraspinatus muscle in the human body. It is a part of the deep fascia, which is a fibrous layer of connective tissue that surrounds individual muscles, groups of muscles, blood vessels, and nerves, binding them together in a manner similar to the original fascia.

Etymology

The term "Supraspinous" is derived from the Latin words "supra" meaning above and "spina" meaning spine. "Fascia" is a Latin term meaning band or bandage. Thus, "Supraspinous Fascia" refers to the bandage above the spine.

Anatomy

The Supraspinous Fascia is located in the upper back region, covering the supraspinatus muscle which is one of the four muscles of the rotator cuff. It is a thick, fibrous and dense structure that provides support and protection to the muscle underneath. It also serves as a medium for the passage of small blood vessels and nerves to the supraspinatus muscle.

Function

The primary function of the Supraspinous Fascia is to provide a protective layer for the supraspinatus muscle. It also helps in the smooth movement of the muscle by reducing friction between the muscle and other surrounding structures. Additionally, it serves as a conduit for small blood vessels and nerves supplying the muscle.

Clinical Significance

In certain medical conditions such as frozen shoulder or rotator cuff tear, the Supraspinous Fascia may become inflamed or damaged, leading to pain and restricted movement. Treatment may involve physical therapy, medication, or in severe cases, surgery.
