Ligaments Flashcards
Coracoclavicular Trapezoid Ligament
stabilizes acromioclavicular joint
Limits medial displacement, protraction, and elevation
Coracoclavicular Conoid Ligament
stabilizes acromioclavicular joint
Limits medial displacement, protraction, and elevation
Acromioclavicular
stabilizes joint, from superior lateral end of clavicle to acromion
Coracoacromial
prevents superior displacement of humeral head
Coracohumeral
reinforces superoanterior aspects of glenohumeral joint capsule
Costoclavicular
stabilizes sternoclavicular joint limiting elevation of the clavicle
Attaches from superior aspect of first rib to undersurface of medial clavicle end
Superior Transverse Scapular
closes off suprascapular notch like a bridge
Glenoid Capsule
circumference of glenoid cavity to anatomical neck of the humerus
Glenohumeral
superior, middle, inferior
All 3 stabilize glenohumeral joint
Ulnar collateral
resists excessive cubital varus
Attaches from medial epicondyle to medial margin of coronoid process &. olecranon process
Radial collateral
resists excessive cubital valgus
Attaches from lateral epicondyle to the anular ligament
Anular
stabilizes proximal radioulnar joint
Attaches from the anterior margin of the radial notch to the posterior margin of the radial notch surrounding the head of the radius
Interosseous membrane
attaches from the interosseous border of the radius to the ulna
Transverse carpal
prevents bowstringing of the tendons of the flexor pollicis longus, flexordigitorum superficialis, & flexor digitorum profundus muscles
Attaches from the pisiform and hook of hamate to the scaphoid and trapezium
Collateral ligaments of metacarpophalangeal joints
stabilizes joint
Attaches from the head of the metacarpals to the base of the adjacent proximal phalanx
