Section 1

Question Answer
boneshumerus, scapula (shoulder blade), clavicle (collarbone)
joint 4 joints: GH, AC, SC, scaupulothoracic joint (false joint)
ligaments tendonsAC joint, coracoclavicular, glenoid laberum
musclesRotator cuff muscles +deltoid + biceps + triceps
nerves axillary, radial, ulnar, median
shoulder pain red flagheart attack, chest
memorize

Section 2

Question Answer
GH joint main nhsoulder joint: ball of humerus fits in glenoid of scapula
SCsupports conenction arms of shoulder to front of chest
ACclavicle meets the acronium
scapulothrocicshoulder blade glides across ribcage
stability of shoulderglenoid laberum + rotator cuff muscles hold humerus tightly into glenoid socket
memorize

Section 3

Question Answer
articular cartilageshock absorber + smooth surface for movement covers ends of bones
ligamentsST connect bone-bone
puprose of ligamentsstability in shoulder for ROM
joint capsule group of ligaments connect humerus to glenoid of scapula
glenoid laberum 1.stability of shoulder joint =connects deep cup for ball of humerus to fit into 2.attachment bicep tendon
memorize

Section 4

Question Answer
bursawater tight sac between 2 moving surfaces= rotator cuff tendons and deltoid- where there is no joint to reduce friction
memorize
bursa irritation: abduction shoulder
Question Answer
roof of shoulder blade acronium
coracoid processbony process protudes anteriorly from scapula
glenoid shallow depression in scapula
blood vessel axillary
memorize

Section 5

Question Answer
shoulder painbicep tendonitis, rotator cuff tear (supraspinatus), glenoid laberum tear
Glenoid labernum tearSLAP tear (bicep tendon inserts on laberum) + BANKHART lesion (shoulder dislocation)
rotator cuff muscles and functionSIts - abduction, external rotation, external rotation,internal rotation
teres minorexternal rotation and adduction
subscapularisinternal rotation and abduction
memorize

Section 6

Question Answer
axillary nerveteres minor + deltoid + regimental patch
axillary nerve injuryweak ABDUCTION + numbness regimental patch
anterior shoulder discolationposition= abduction,external rotation
cause of anterior dislocation by ageyoung=axillary nerve old=rotator cuff tear
anterior dislocation associated pathologyrotator cuff tear+ laberal tear+ humeral head fractures
treatment anterior dislocationreduction (surgery reserved for recurrent dislocation)
test for shoulder dislocationtouch other shoulder
posterior dislocation positionshoulder locked in internal rotation (lack of external rotation)
problems with identify posterior dislocation50% missed on XR - must use axillary XR
