Upper Extremity Arthrology Flashcards
(107 cards)
shoulder girdle
manubrium, clavicle, scapula and humerus
SC, AC, and glenohumeral joints
sternoclavicular joint classification
sellar (saddle) synovial joint (articular capsule and disc)
sternoclavicular joint Bs.
between clavicular notch of manubrium and sternal facet on sternal end of clavicle
sternoclavicular joint Ls.
costoclavicular L.
anterior sternoclavicular L.
posterior sternoclavicular L.
interclavicular L.
acromioclavicular joint classification
planar synovial joint (articular capsule and disc)
acromioclavicular joint Bs.
between acromial facet on the acromial end of the clavicle and the facet on the acromion of the scapula
acromioclavicular joint Ls.
acromioclavicular L.
coracoclavicular L. (trapezoid L. and conoid L.)
AC joint injury
“shoulder separation”
capable of separating with or without rupture of the coracoclavicular L.
glenohumeral joint classification
spheroidal synovial (articular capsule, labrum, and bursae)
glenohumeral joint Bs.
between glenoid cavity of scapular head and head of humerus
glenohumerual joint Ls.
glenohumeral L.
coracohumeral L.
transverse humeral L.
coracoacromial arch
coracoacromial arch
osseoligamentous arch preventing superior displacement of humerus from glenoid cavity
coracoacromial L.
glenoid labrum
deepens and supports cavity of the scapular head
bursae of the glenohumeral joint
subscapular bursa and subacromial bursa
subscapular bursa
between subscapularis T. and the scapular neck, communicates with synovial membrane of glenohumeral joint
subacromial bursa
between the deltoid M., supraspinatus T. and articular capsule, does not usually communicate with synovial membrane of glenohumeral joint
fibrous capsule of glenohumeral joint is open in two places to allow passage of
long head of biceps brachii T. and subscapular bursa
GH joint dislocation
susceptible due to mobility and relative instability
due to presence of coracoacromial arch, dislocation of the GH joint most commonly occurs anteriorly or inferiorly
elbow joint classification
ginlymus (hinge) synovial joint (articular capsule, humeroulnar joint, humeroradial joint, bursae)
continuously distally with synovial membrane of proximal radioulnar joint
humeroulnar joint Bs.
trochlear notch of ulna wrapping around humeral trochlea
humeroulnar joint Ls.
ulnar collateral L. of elbow (anterior band, posterior band, oblique band)
humeroradial joint Bs.
humeral capitulum articulating with fovea of radial head
humeroradial joint Ls.
radial collateral L. of elbow (blends with annular L. of radial head)
bursae of the elbow joint
olecranon bursae
subcutaneous bursa of medial humeral epicondyle
subcutaneous bursa of lateral humeral epicondyle
bursa of anconeus
bursa at origin of extensor carpi radialis brevis M.
bicipitoradial bursa
