1

Name for shoulder joint

scapulo-humeral joint

2

Structure of shoulder joint

ball & socket

3

Function of shoulder joint

hinge joint (cursorial specialization)

4

Joint capsule for scapulo-humeral joint

capacious & extends under the tendon of origin of the biceps brachii
thickened laterally & medially into collateral/ glenohumeral ligaments

5

Ligaments tht keeps biceps brachii tendon in place

transverse humeral ligament

6

Why are large tendons & muscles recruited for stability of the shoulder joint

shallow glenoid cavity & weak collateral ligaments

7

Muscles & tendons that help stabilize the shoulder joint

medially: subscapularis & corocobrachialis
laterally: infraspinatus & teres minor
craniomedially: supraspinatus & tendon of biceps brachii

8

Osteochondriosis dessicans

occurs in goldens, labs, Newfoundlands, Bernese Mtn dogs, & mixed breed

9

Osteroarthritis

any breed

10

Injuries related to shoulder joint

medial glenohumeral ligament injury
biceps tendonitis/ tenoynovitis
luxation/ dislocation of the shoulder joint

11

Although luxation/ dislocation of the shoulder joint is rare, what could cause it

injury to suprascapular nerve

12

Name for elbow joint

cubital jont (also a compound joint)

13

Joints that make up the elbow joint

humeroradial joint
humeroulnar joint
radioulnar joint

14

Joint in elbow that bears most of the weight

humeroradial joint

15

Part of humeroradial joint that bears most of the weight

capitulum of the humerus (lateral condyle)

16

Humeroulnar joint is formed b/w

trochlea of the humers (medial condyle)

17

Is the cubital joint stable

yes-> strong collateral ligaments

18

Ligaments of cubital joint

medial & lateral collateral ligaments
oblique ligaments
olecranon ligament
annular ligament
interrosseus ligament

19

Medial & lateral collateral ligaments cubital joint

medial & lateral epicondyles to radius/ ulna

20

Oblique ligament

cranial to medial

21

Olecranon ligament

caudal, joins medial condyle to olecranon

22

Annular ligament

cranial to radius; stabilizes proximal radioulnar joint
allows for pronation & supination

23

Interosseus (radioulnar) ligaments

cover interosseous space b/w radius & ulna

24

How does the interosseous ligaments change as the dog ages

elastic -> collagen -> ossified tissue

25

Anconeus muscle

covers margins of olecranon fossa of humerus & olecranon

26

Cubital joint illnesses

joint incongruity
metabolic deficiencies
fragmented coronoid process
un-united/ fragmented anconeal process
luxation/ dislocation of elbow joint

27

Fragmented coronoid process & un-united/ fragmented anconeal process common in what breeds

Goldens, Labs, Newfoundlands, Bernese Mtn dogs, & mixed breeds

28

Un-united anconeal process is especially common in German Shephards. What is a pre-disposing factor

ulnar distal growth injury

29

When can un-united anconeal proces be diagnosed

after 24 weeks

30

How would luxation/ dislocation of the elbow joint occur

forced medial impact on the forearm or a lateral impact on the arm in a flexed lebow could dislocate the radius & ulna LATERALLY
