Rotator Cuff Tear
Understanding Rotator Cuff Tear found on Shoulder Magnetic Resonance Imaging imaging. Learn what this finding means and what steps to take next.
Radiographic Appearance
Magnetic Resonance Imaging FindingDiscontinuity or retraction of supraspinatus/infraspinatus tendon with fluid signal in defect; muscle atrophy or fatty change may be present.
Clinical Significance
Causes pain and weakness; chronic tears may become irreparable.
What is a Rotator Cuff Tear?
Tear of the tendon complex stabilizing the humeral head. MRI grades partial vs full-thickness tears.
Imaging Appearance
- Fluid-bright gap in tendon
- Tendon retraction toward glenoid
- Muscle atrophy or fatty infiltration on T1
- Subacromial/subdeltoid bursal fluid
Clinical Significance
- Influences surgical reparability and prognosis
- Massive tears can cause pseudoparalysis
Symptoms
- Lateral shoulder pain, weakness with overhead activity
Diagnosis
- MRI shoulder without contrast
- Physical tests: Jobe, external rotation strength
Treatment
- Physical therapy, injections
- Arthroscopic repair or debridement depending on tear
Prognosis
- Better when repaired early; chronic retraction worsens outcomes
What Should You Do?
- Avoid heavy overhead lifting until evaluated.
- Begin rotator cuff and scapular stabilizer exercises as advised.
- Discuss surgical options if weakness or night pain persists.
