Deltoid fascia
Fascia deltoidea · Deltová povázka
Fascia & connective tissue
Looks like
A thin sheet of fascia over the deltoid muscle.
What it does
Wraps the deltoid and blends into the fascia of the chest in front and the back behind.
Keeping it well
Rarely a problem alone; shoulder pain on lifting the arm usually comes from the rotator cuff beneath the deltoid.
