The Shoulder Complex Flashcards
What are the four basic mechanical characteristics of the shoulder?
Motion, strength, stability, and smoothness
Referred symptoms from the shoulder are usually found in the what dermatome?
C5
T or F: the scapulothoracic joint has a capsular pattern
False
What is is the capsular pattern for the glenohumeral joint ? (Most restricted to least restricted)
ER, Abduction, IR
What is is the capsular pattern for the acromioclavicular joint ? (Most restricted to least restricted)
HAD and full elevation
What is is the capsular pattern for the sternoclavicular joint ? (Most restricted to least restricted)
HAD and full elevation
What is painful arc?
a condition in which the tissues in the subacromial space become inflamed causing pain
Degenerative changes to the RTC, acromion process, coracoid process, and anterior tissues from stress overload resulting in impingement are considered primary or secondary impingement?
Primary Impingement
The shape of the acrominon and degeneration of the coracoacromial ligament is considered extrinsic or intrinsic?
Extrinsic
What is a primary cause of secondary impingement?
Altered muscle dynamics in the ST joint and GH joint
T or F: bursitis can increase with age
True
list some special tests for impingement
Hawkins-Kennedy test, Neer Impingement test, Cross over Impingement test, Yergason Test, Empty Can
list some special tests for bicipital tendinits
Speed’s test and Ludington’s Sign
T or F: frozen shoulder is more common in men and stroke patients
False
More common in women and diabetics
T or F: atraumatic dislocation is a less common cause of shoulder dislocation
True
*Special tests: instability
*Inferior Multidirectional
-Sulcus sign
-Feagan (Feagin) test
Anterior
-Anterior Drawer test
-Surprise Test
-Load and Shift test
-Crank
Posterior
-Posterior Drawer Test
-Jobe Relocation Test
-Load and Shift test
special tests: dislocation
apprehension tests (anterior and posterior)
What ligament is responsible for preventing anterior humeral translation in the 90/90 position?
Inferior Glenohumeral Ligament
Special tests: labral tear
O’Brien test, Crank test, Biceps Load/tension test: SLAP, Drop Arm test, Posterior Impingement test, Grind test, Clunk test
What does the acronym TUBS represent?
Traumatic MOI
Unilateral Shoulder Involvement
Bankart and Hill-Sachs glenohumeral Fractures
Surgery often required for management
What do the acronym AMBRI represent?
Atraumatic mechanism Multidirectional instability Bilateral Shoulder involvement Rehabilitation as primary management Inferior Capsular shift surgery
Explain the differences between a Grade I, II and III AC Joint sprain?
Grade I: minor strain to the fibers of the AC ligaments, joint remains stable, and ligaments intact, no palpable deformity
Grade II:rupture of the AC ligaments, distal end of the clavicle is unstable, but the Coracoclavicular ligaments are intact
Grade III:disruption of the AC and Coracoclavicular ligaments. On PE, may be less painful than a Type II. GH Abduction generally causes the most severe pain, clavicle may be prominent enough to tent the skin.
What is the main action of the Supraspinatus?
Abduction
What is the main action of the Infraspinatus and Teres Minor?
External Rotation
What is the main action of the Subscapularis?
Internal Rotation
How is Subacromial impingement characterized?
by anterior/lateral shoulder pain and weakness, esp. with overhead activities
Tests for Neurovascular Compression
Adson's Manuever Allen's Test *Roos Test (most clinically accurate) Military Brace Position Brachial Plexus Stretch test
