Abstract
We discuss aspects of glenohumeral instability and rotator cuff tears in a clinically orientated approach, presenting a new way of quantifying structural bone loss from the anterior glenoid and defining the Glenoid Index as an indicator of the appropriate surgical approach to address anterior instability.
Repair of the rotator cuff depends on viable and functional muscular tissue. We discuss the potential for repair of the supraspinatus tendon in relation to the tangent sign, fat infiltration and retraction. Comparing MRI and arthroscopic findings, we highlight pitfalls in the diagnosis and repair of the subscapularis tendon.
