Name for shoulder joint
scapulo-humeral joint
Structure of shoulder joint
ball & socket
Function of shoulder joint
hinge joint (cursorial specialization)
Joint capsule for scapulo-humeral joint
capacious & extends under the tendon of origin of the biceps brachii
thickened laterally & medially into collateral/ glenohumeral ligaments
Ligaments tht keeps biceps brachii tendon in place
transverse humeral ligament
Why are large tendons & muscles recruited for stability of the shoulder joint
shallow glenoid cavity & weak collateral ligaments
Muscles & tendons that help stabilize the shoulder joint
medially: subscapularis & corocobrachialis
laterally: infraspinatus & teres minor
craniomedially: supraspinatus & tendon of biceps brachii
Osteochondriosis dessicans
occurs in goldens, labs, Newfoundlands, Bernese Mtn dogs, & mixed breed
Osteroarthritis
any breed
Injuries related to shoulder joint
medial glenohumeral ligament injury
biceps tendonitis/ tenoynovitis
luxation/ dislocation of the shoulder joint
Although luxation/ dislocation of the shoulder joint is rare, what could cause it
injury to suprascapular nerve
Name for elbow joint
cubital jont (also a compound joint)
Joints that make up the elbow joint
humeroradial joint
humeroulnar joint
radioulnar joint
Joint in elbow that bears most of the weight
humeroradial joint
Part of humeroradial joint that bears most of the weight
capitulum of the humerus (lateral condyle)
Humeroulnar joint is formed b/w
trochlea of the humers (medial condyle)
Is the cubital joint stable
yes-> strong collateral ligaments
Ligaments of cubital joint
medial & lateral collateral ligaments oblique ligaments olecranon ligament annular ligament interrosseus ligament
Medial & lateral collateral ligaments cubital joint
medial & lateral epicondyles to radius/ ulna
Oblique ligament
cranial to medial
Olecranon ligament
caudal, joins medial condyle to olecranon
Annular ligament
cranial to radius; stabilizes proximal radioulnar joint
allows for pronation & supination
Interosseus (radioulnar) ligaments
cover interosseous space b/w radius & ulna
How does the interosseous ligaments change as the dog ages
elastic -> collagen -> ossified tissue
