1

What are the 2 joints that make up the shoulder

glenohumeral and acromioclavicular

2

What structures stabilise the shouler joint?

capulse; rotator cuff and otehr muscles, labrum

3

What can cause impingement?

tendonitis; cuff tear; subacromial bursitis; osteophytes from AC joint

4

Where does a rotator cuff tend to occur?

in the supraspinatus tendon and then travels either anteriorly or posteriorly

5

What can occur if there is recurrent anterior discolation and the labrum commonly detaches?

Bankart lesions- which is a pocket that is created that the humerus can dislocate into

6

What is the nerve most commonly compromised with anterior shoulder dislocation?

axillary

7

What space does the axillary nerve travel through?

the quadrangular space

8

What are the boundaries of the quadrangular space?

superior- teres minor
inferior- teres major
medial- nck of humrus
lateral- long head of triceps

9

What is adhesive capsulitis better known as?

frozen shoulder

10

What symptoms does frozen shoulder present with?

global loss of ROM - ESPECIALLY ER

11

What nerve supplies sensation to the lateral forearm?

musculocutaneous

12

What nerve is susceptible to injury in humeral shaft fractures?

radial nerve

13

What is seen when there is damage to the radial nerve?

wrist drop

14

What are the 2 joints at the elbow?

humero-ulnar joint
radio-capitellar joint

15

Where does the common extensor tendon originate?

lateral epicondyle

16

Where does the common flexor tendon originate?

medial epicondyle

17

What is at risk of injury in a supracondylar fracture?

brachial artery and median nerve

18

What joints facilitate supination and pronation?

proximal and distal radio-ulnar joints

19

What nerve supplies the majority of the anterior forearm?

median nerve

20

What nerves are supplied by the ulnar nerve in the anterior forearm?

FCU and ulnar half of FDP

21

What muscles orginiate at the common extensor origin?

extensor carpi radialis brevis
extensor digitorum

What forms the lower border of the snuffbox?

extensor pollicis brevis tendon

25

What arteries supply the head and neck of femur?

retinacular arteries

26

What is the function of gluteus maximus?

extension and external rotation

27

Which nerve supplies the anterior thigh muscles?

femoral nerve

28

Whic hnerve supplies the posterior thigh mucles?

sciatic nerve

29

What nerve supplies the adductor muscles?

obturator nerve

30

Where can the obturator nerve refer pain from the hip?

knee

31

What type of cartilage are the menisci made up of?

fibrocartilage

32

What does the ACL resist?

internal rotation and anterior translation of the tibia

33

What does the LCL resist?

varus stress and helps resist

valgus stress

35

What does the PCL resist?

posterior translation tibia or anterior translation femur
