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 Finding

Discontinuity 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?

  1. Avoid heavy overhead lifting until evaluated.
  2. Begin rotator cuff and scapular stabilizer exercises as advised.
  3. Discuss surgical options if weakness or night pain persists.
