The scapula or shoulder blade is an impressive anatomical structure. Suspended by only two ligaments, three layers of muscle and bursae (small, fluid-filled sacs that reduce friction between muscles, tendons, and bone), are all that support the structure. There isn’t a real joint between scapula and trunk, but movement is possible, and therein lies the scapula’s uniqueness.
Unfortunately, this uniqueness also makes the scapula prone to specific conditions, of which one of the most common is the snapping scapula syndrome, a condition characterized by popping, grinding, grating, or ‘snapping’ of bones and tissue in the shoulder blade when the arm is lifted, moved, or rotated. The snapping can be audible, and at times be painful. If it starts to affect movement and flexibility it will need to be checked by a sports physiotherapist.
