Scapulo-thoracic articulation is not in the strict sense of the term an articulation.

We use the term articulation because the movements in question are far from being innocuous!

The total mobility of the shoulder (arms vertically, rotations) corresponds to an associated mobility of the glenohumeral and scapulothoracic.

There are also lateral and superior movements of the scapula as shown in the diagram opposite.

& Nbsp;

To be convinced of this it is necessary to block the movements of the scapula by holding it firmly by a hand on the top of the shoulder, then the shoulder does not go up to the vertical …

The arm above the shoulder implies a rocking of nearly 180 ° of the scapula.

Conditions

The pathologies of scapulothoracic are less frequent and especially less clearly identified than other joints.
