Anatomical Relations

The deltoid fascia descends from the periosteum of numerous bones, including the acromion, crest of the scapular spine, and the superior part of the medial border of the scapula. Inferiorly, the deltoid fascia is continuous with the brachial fascia and lateral intermuscular septum. Anteriorly, it is continuous with the pectoral fascia. Posteriorly, the thickened borer of the deltoid fascia is continuous with the infraspinous fascia. The acromial branch of the thoracoacrominal vein descends on the posterior aspect of the deltoid fascia, while the superior lateral brachial cutaneous nerves ascend on the posterior aspect.

Structure

The deltoid fascia is adherent to the external aspect of the central part of the deltoid muscle. It is a deep fascial layer that is thickest anteriorly and posteriorly. Numerous septa of the deltoid fascia penetrate between the fascicles of the muscle.

Function

The deltoid fascia gives an attachment for the deltoid muscle, in addition to the bony insertion and origin points. The large attachment area for the muscle increases the effectiveness and efficiency of its action (Standring, 2016).

The fascia is also defined as a “the fascial system consists of the three-dimensional continuum of soft, collagen containing, loose and dense fibrous connective tissues that permeate the body” by Fascia Nomenclature Committee (Bordoni and Whitte, 2018), an as “masses of connective tissue large enough to be visible to the unaided eye” by Gray’s Anatomy (Standring, 2016).
