Rotator Cuff Tear
了解 Shoulder Magnetic Resonance Imaging 影像中的 Rotator Cuff Tear，明确其含义与下一步措施。
影像表现
Magnetic Resonance Imaging FindingDiscontinuity or retraction of supraspinatus/infraspinatus tendon with fluid signal in defect; muscle atrophy or fatty change may be present.
临床意义
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.
