The rotator interval

The rotator interval is being written about quite a bit these days. It is the space between the supraspinatus and subscapularis tendons and has its base at the coracoid process.

The two major conditions to look for are adhesive capsulitis, where there is increased signal within the rotator interval with soft tissue and tears.

These are best visualized on axial and sagittal images, using PD FSE or T2 FSE.

The best review of the rotator interval and its anatomy and pathologies is in a recent issue on Shoulder in the Magnetic Resonance Imaging Clinics.
