  1. Rotator Cable: an arching, cable-like thickening of the RTC. The rotator cable is 2.59 times the thickness of the rotator crescent that it surrounds and functions to stress-shield the rotator crescent. (Burkhart SS, Arthroscopy 1993; 9: 611-616)
  2. Rotator Crescent: thinner crescent of tissue that inserts into the greater tuberosity.
  3. Greater tuberosity insertion
