The anatomy and mechanics of the acromio-clavicular joint is analyzed. It is found that the anterior deltoid muscle, normally considered an important flexor of the arm, fulfills quite another purpose when the arm is flexed. The sole reason for its activity in this position is to delimit shear forces in the acromio-clavicular joint. An experimental in vitro method to carefully analyze the joint geometry and kinematics, based on video recordings of markers, is discussed.
