Rotator cable

Last revised by Yuranga Weerakkody on 26 Mar 2019

The rotator cable is a fibrous structure associated with the rotator cuff. It is located at the medial aspect of the rotator crescent and formed by a thick bundle of fibers perpendicular to the supraspinatus and infraspinatus tendons. This morphology can be variable.

Radiographic features


May be seen as a curvilinear structure running perpendicular and beneath the superior rotator cuff (i.e. supraspinatus and infraspinatus).


It may be seen in ~75% of cases on MRI 1:

  • T2/PD: seen as a linear band of hypointense signal intensity along the undersurface of the supraspinatus and infraspinatus tendons
  • according to one MRI study, it had a mean width of around 12 mm and was located approximately 13 mm from the rotator cuff humeral bony insertion
