Rotator Interval Anatomy & Subcoracoid Impingement Biomechanics

Topic Summary & Background: Cadaveric and high-resolution MRI correlation of the coracohumeral ligament, superior glenohumeral ligament, and biceps reflex pulley in shoulder anterior stability.

Key Discussion Questions:
  • Anatomical boundaries of the Rotator Interval and clinical signs of laxity.
  • Subcoracoid vs Subacromial impingement differential clinical tests.
  • Vascular supply of supraspinatus critical zone (Codman's area).
Standard Clinical Consensus: Standard Anatomical Consensus: The Rotator Interval plays a vital role as a static stabilizer against inferior and anterior glenohumeral translation at 0° abduction.
