What is a Rotator Cuff Tear?

Anatomy and Degenerative Tendon Failure

The rotator cuff comprises the supraspinatus, infraspinatus, teres minor, and subscapularis tendons. Mechanical subacromial abrasion combined with hypovascularity makes the supraspinatus insertion particularly susceptible to full-thickness tearing.

Key Clinical Manifestations

• Acute or progressive lateral shoulder pain during elevation
• Severe sleep disturbance when lying on the affected side
• Subjective muscle weakness during abduction and external rotation
• Loss of functional dexterity in overhead reaching

Frequently Asked Questions

How is a torn rotator cuff repaired?

Minimally invasive arthroscopic shoulder surgery utilizing bio-absorbable suture anchors secures the avulsed tendon back to its anatomical footprint on the greater tuberosity.
