Which two anatomical structures are connected by the Arthroflex component used in SCR?

• A. Glenoid rim and Supraspinatus
• B. Superior Glenoid and Supraspinatus
• C. Inferior Glenoid and Infraspinatus
• D. Coracoid process and Subscapularis

Answer: (B)

The key idea is that the Arthroflex graft used in superior capsular reconstruction bridges the upper part of the glenoid to the supraspinatus region to recreate the shoulder’s superior restraints. This configuration places a static constraint between the superior glenoid and the supraspinatus footprint on the humeral head, helping to prevent upward migration of the humeral head when the rotator cuff is deficient. By anchoring medially at the superior glenoid and laterally at the supraspinatus footprint, the graft reconstructs the superior capsule and centralizes the joint during movement. Other pairings wouldn’t restore that specific superior constraint: they would involve different tissues or an incorrect region, and wouldn’t recreate the same stabilizing effect.
