MSK- Shoulder Flashcards
4 joints of the shoulder
Sternoclavicuar
AC
GH
Scapolothoracic (not a true joint
Capsular pattern of GH joint and loose pack
Loss of ER>ABD>IR
30 flex, 60 abd, slight IR (loose pack)
TOS borders
Ant: clavicle, crocodile process, pec minor
Post: UFT, scap
Medica: scalene ecusle, R1
Lateral: axial lateral
Contains (TOS)
Brachial plexus, subclavian artery and vein
Types of TOS
Neurogenic (true TOS) (anatomical abnormalities)
Nonspecific “symptomatic” neurogenic (diagnosed upon exclusion diagnosis )
Vascular- arterial (subclavian artery)
Vascular- venous
TOS S&S
Neurogenic
- weak grip, numbness, parathesisa
Vascular
- cool and pale extremities
Classifications of TOS
Scalene anterior syndrome
Costoclavicular
Hyperabduction
Cervical rib
TOS- special tests
Adson Maneuver
Costoclavicular syndrome test
Halstead maneuver
Wright test
Allen test
ROOS test (elevated arm stress test)
Shoulder girdle passive elevation
Shoulder separation (AC separation)
Trauma to the ligs of AC
Look for step deformity, tenderness, pain in add, elevation and HBB (hand behind back)
Shoulder seperation special test
Cross body (horizontal) adduction test
Glenohumeral jt stability- classifications
Direction
Degree
Etiology
Timing
What direction is more common for shoulder dislocation?

Inferior for stroke populations
What position causes dislocation to occur?
Abduction and external rot
What other tissues can be damaged from ant dislocation
Sub scap, long head bicep (fill in more)
Potential complications of Shoulder dislocations
Auxiliary nerve

Shoulder instability special tests
Anterior
- crank (apprehension relocation)
- apprehension release (surprise)
- load shift

Primary (idiopathic)
Secondary (trauma or long periods of immobile)
Correlation with anxiety
FRZN shoulder S&S
ER>ABD>IR
HBB, HBH, overhead
