What is a rotator cuff tear?

A partial or full‑thickness tear of the supraspinatus, infraspinatus, teres minor, or subscapularis tendons.

2
New cards
What is the most commonly torn rotator cuff tendon?

Supraspinatus.

3
New cards
What mechanisms cause a rotator cuff tear?

  • Acute trauma (fall on outstretched arm)

  • Chronic degeneration from overuse.

4
New cards
Who is at highest risk for rotator cuff tears?

  • Older adults

  • Overhead athletes

  • Laborers

  • Patients with chronic impingement.

5
New cards
What symptoms occur in a rotator cuff tear?

  • Shoulder pain

  • Weakness

  • Difficulty lifting arm

  • Night pain.

6
New cards
What physical exam findings suggest a rotator cuff tear?

  • Painful arc

  • Weakness with abduction

  • Weakness with external rotation

  • Positive impingement signs.

7
New cards
What special tests suggest supraspinatus tear?

Empty can test weakness or pain.

8
New cards
What special test suggests infraspinatus tear?

External rotation weakness.

9
New cards
What special test suggests subscapularis tear?

Lift‑off test weakness.

10
New cards
What special test suggests rotator cuff pathology in general?

Drop arm test.

11
New cards
What imaging is used for rotator cuff tear?

MRI is the best test

12
New cards
What X‑ray findings may be seen?
High‑riding humeral head in chronic tears.
13
New cards
What are treatment goals for rotator cuff tear?

  • Reduce pain

  • Restore function

  • Improve strength.

14
New cards
What is initial treatment for rotator cuff tear?

  • Rest

  • NSAIDs

  • Physical therapy.

15
New cards
What physical therapy focuses on in rotator cuff tear?
Strengthening of rotator cuff and scapular stabilizers.
16
New cards
When is surgery indicated for rotator cuff tear?

  • Full‑thickness tear

  • Failure of conservative therapy

  • Significant weakness

  • Acute traumatic tear in young patient.

17
New cards
What complications may occur in rotator cuff tear?

  • Chronic weakness

  • Loss of ROM

  • Shoulder instability

  • Adhesive capsulitis.

18
New cards
What is the most serious complication of untreated rotator cuff tear?

Progressive tendon retraction and irreversible muscle atrophy.

19
New cards
What follow‑up is required after rotator cuff tear?
Monitor strength, ROM, and response to PT
20
New cards
What conditions mimic rotator cuff tear?

  • Shoulder impingement

  • Adhesive capsulitis

  • Biceps tendinopathy

  • Glenohumeral arthritis.

21
New cards
What feature differentiates rotator cuff tear from impingement?

Tear has true weakness, not just pain‑limited motion.

22
New cards
What feature differentiates rotator cuff tear from adhesive capsulitis?

Adhesive capsulitis has loss of passive ROM, not just active weakness.
