Abstract

Rotator cuff tears (RCT) are a complex pathology of the shoulder which may result from trauma or chronic degeneration and are often multifactorial in nature. The concept of mechanical impingement of the supraspinatus tendon underneath the acromion was first introduced by Armstrong [1] in 1949 and was later verified and popularized by Neer [2]. In 1986, Bigliani et al. [3]. identified three distinct acromial shapes and found the hooked type acromion to be the most strongly associated with rotator cuff pathology. By Banas et al. [4] described an increase in RCTs and subacromial disease with a decreasing lateral inclination angle of the acromion.
