MSK: Shoulder Flashcards
One of the most common problem in the shoulder d/t impingement
Supraspinatus Tendon
Innervation of GH ligaments
Branches of posterior cord
Suprascapular
Axillary
Lateral pectoral
Most important ligament in the GH joint and is damaged d/t anterior dislocation
Inferior GH jt.
Primary support of AC jt.
Control the vertical motion of clavicle
First lig. injured when the joint is stressed. – Step Deformity
Coracoclavicular lig.
70% of rotator cuff tears are associated with this type of acromion
Type 3 - Hooked (39%)
Types of AC jt.
Type 1 -Flat (17%)
Type 2 –Curved (43%)
Type 3 -Hooked (39%)
Type 4 –Convex/Upturned (1%)
Innervation of AC jt.
Branches of suprascapular and lateral
pectoral nerve
Main lig. for maintaining integrity of SC jt.
Rhomboid / Costoclavicular ligament
Innervation of SC jt.
Ant. supraclavicular nerve & nerve to subclavius
A stable ______ enables the rest of the shoulder to function correctly
Scapula
Phase 1 of Scapulohumeral Rhythm
Humerus: 30 abd
Scapula: Min movement (setting phase)
Clavicle: 0-5 elevation
Phase 2 of Scapulohumeral Rhythm
Humerus: 40 abd
Scapula: 20 rot, min protraction or elevation
Clavicle: 15 elevation
Phase 3 of Scapulohumeral Rhythm
Humerus: 60 abd, 90 lat rot
Scapula: 30 rot
Clavicle: 30-50 post rot, up to 15 elev
Glenohumeral painful arc
45-60 to 120
Acromioclavicular painful arc
170 - 180
SICK Scapula
malpositioned Scapula
prominent Inferior medial border
Coracoid pain and malposition
scapular dysKinesia
Inf med border prominent at rest, scapular tilt, while the acromion
tilts anteriorly over the top of the thorax
Type I
Classic winging; whole medial border prominent and lifting away
Type II
Superior border elevated, overactivity of upper traps and lev scap (Most common)
Type III
Scapulae symmetrical, rotary winging
Type IV
