What is shoulder impingement?
A concept first introduced by Neer in 1972 to describe mechanical impingement of the rotator cuff tendon.
This runs above the humeral head and glenoid, and below the acromial process, coracoacromial ligament,
and acromioclavicular joint. Recurrent friction causes bursitis, tendinitis, and ultimately, tendon degeneration
and tearing.
