Abstract
Rotator cuff pathology is one of the most common conditions affecting the shoulder. Anatomic studies detailing rotator cuff tears in cadavers have noted a prevalence ranging from 17% to 72% (1,2)
Rotator cuff tears are among the most frequently encountered causes of pain and dysfunction in the shoulder (3). Rotator tears can be secondary to various etiologies: First, impingement syndrome and then instability or trauma (4). In all clinical reports, the incidence of cuff defects is relatively low before the age of 40 years, begins to rise in the 50-to 60-year-old age group, and continues to increase in the 70 years and older age group (5). Rotator cuff pathology may be graded arthroscopically using the “ABC” system in which “A” represents the articular side of the cuff, “B” is bursal, and “C” denotes a complete tear connecting the two surfaces (6).
