Impact of Critical Shoulder Angle and Acromial Index on Surgical Outcomes

What is it about?

The critical shoulder angle (CSA) is a new radiological parameter which has generated interest as a powerful predictor of the occurrence of rotator cuff tears. The acromial index (AI) is yet another radiological parameter associated with full thickness rotator cuff tears. This study examines the influence of CSA and AI on the outcomes of arthroscopic rotator cuff repair.

Why is it important?

This study is a large single-surgeon series that attempts to investigate the influence of preoperative CSA and AI on functional outcomes post-operatively. Shoulder surgeons should be aware that increased CSA and AI do not appear to negatively influence function outcomes and hence should not be regarded as contraindications to arthroscopic rotator cuff surgery.
