Shoulder impingement can be subdivided into primary and secondary impingement. Primary im-pingement is a mechanical obstruc-tion of the rotator cuff tendons un-der the anterior inferior one-third of the acromion, the coracoacromial ligament, and sometimes the acro-mioclavicular joint (42).houlder impingement can be subdivided into primary and secondary impingement.

If this process continues it can produce deep localised attack of the type known as erosion-corrosion or impingement damage. The actual attack on the metal is by the corrosive action of the water to which it is exposed while the erosive factor is the mechanical removal of the corrosion product from the surface.
