Shoulder Complex- RC Tear thru FSCS Flashcards
What are risk factors/etiologies for a rotator cuff tear?
- Gradual or degenerative tears including with repetitive overhead activities
- Acute tears, higher UE velocity, heavy lifting, impact (FOOSH)
What are the most common structures involved with a rotator cuff tear?
Supra or infraspinatus muscles
- possibly others
What are rotator cuff tears graded by?
size - S, M, L
partial or full thickness tear
What can cause a partial tear?
Excessive compression underneath tendon, wears away fibers
How often are the labrum and biceps involved with rotator cuff tears?
40-75% involved
What is a SLAP tear?
Superior Labral anterior/posterior tear
What causes a SLAP tear?
Long head of biceps excessively contracts and tears labrum
What may we have to have done to repair a SLAP tear?
surgically fixate biceps tendon (aka tenodesis)
What other trauma aside from a SLAP tear can cause a labrum and biceps tear?
Compression onto labrum with FOOSH
What are symptoms of a rotator cuff tear?
like impingement (INFLAMMATION) plus…
- acute or persistent
- hx of pop, click , or catch (high spec for labral tear)
- increased pain with repetitive overhead activities
What are signs of a rotator cuff tear?
Like impingement plus…
- painful arc around 90 degrees of elevation
- resisted/ MMT weak and painful
* flx & rotator cuff, particularly abd / ER/ possibly IR
- combined motions - possible inconsistent block
- stress tests possibly positive
What are some special test signs of a rotator cuff tear? How effective?
LR + = 9.84 if all positive, LR- = .54 if all negative
- over 65 yo
- weak ER
- night pain
What are indicators of a full thickness tear? How effective?
LR+ =28 if all positive, LR- = .09 if all negative
- over 60 yo
- positive painful arc, drop arm, and infraspinatus test
What is a test for the supra and infraspinatus? LR?
ER lag sign
LR+ = 5-28
What is a special test for. supraspinatus?
Drop arm - high spec (RULE OUT)
What are some tests for non-specific tears?
Empty can - high sens (RULE IN)
Jobe test - LR+=7.36; LR-=.1
What are some special tests for subscapularis?
Lift off - high spec (rule out)
Belly press (LR+ = 12.5-20)
Bear hug (LR+ = 7.23)
What special tests could possibly be positive (what structures)with a tear ?
For labrum and biceps
What is our patient rX for a rotator cuff tear?
Early ROM with degenerative tears
What is the ultimate purpose of MET for a rotator cuff tear?
Stabilization
Tissue proliferation for involved tissues
What is the biggest predictor of a tear going to sx?
A patients negative perception
What is the patients negative perception effecting surgery irrespective of?
size of tear
retraction
fatty inflitration
age
pain
What is retraction?
Tear of a tendon or muscle that is rather elastic, tear it and have it roll up, retracts away from attachment
- if there a while, loses ability to heal
What is the effectiveness of corticosteroid injections with rotator cuff tears?
No evidence of effectiveness within 4 weeks of shot
- only provides transient relief
