– Rotator Interval Capsule: – rotator interval is a triangular portion of shoulder capsule which lies between the supraspinatus and subscapularis tendons; – capsular anatomy: (Static Stabilizers / Capsule of the Shoulder) – interval capsule is reinforced by the superior glenohumeral and coracohumeral ligaments; – references: – Capsular ligaments … Read more
– Discussion: – impingement syndrome describes pain in subacromial space when the humerus is elevated or internally rotated; – during humeral flexion, the supraspinatus tendon and bursa become entrapped between the anteroinferior corner of the acromion (and CA ligament) and the greater tuberosity; – this syndrome is thought to precipitate attritional changes in the rotator … Read more
