questions !

Question 1

inability to use a screwdriver is most likely due to dysfunction in what muscle?

Answer 1

biceps brachii

major function = supination + elbow flexion

Question 2

which bone moves in pronantion to supination?

Answer 2

radius
–> moves on ulna, radial head moves on capitulum of humerus

ulna, humerus, carpals, scapula all static

Question 3

contents of the antecubital fossa

Answer 3

radial nerve
tendon of biceps
brachial artery
medial nerve

Question 4

tender + bruised over lateral aspect of leg just below knee + unable to dorsiflex foot

Answer 4

foot drop following fibular neck fracture which has damaged the common peroneal nerve

Question 5

where does the long head of biceps brachii originate from?

Answer 5

supraglenoid tubercle of scapula

Question 6

which pulse is found lateral to extensor hallucis longus tendon?

Answer 6

dorsalis pedis

Question 7

triceps blood supply, action, insertion + innervation

Answer 7

blood supply - profunda brachii artery

action = elbow extention

insertion = olecranon of ulna

innervation = radial nerve

Question 8

how does the periosteum ofchilds long bones compared to that of adults?

Answer 8

thicker in kids

–> greenstick fractures, bones more elastic + pliable, tends to remain intact which helps with stability + reduction

Question 9

how are proximal humeral fractures most commonly treated?

Answer 9

majority are managed non-operatively in a colar + cuff for 3-4weeks

(shoulder joint is highly mobile, small angulation can be tolerated)

Question 10

common cause of proximal humeral fractures?

Answer 10

low energy injuries in osteoporotic
fall onto outstretched hand
fall directly onto the shoulder

Question 11

Finger flexor tendon injuries may occur secondary to a penetrating wound to the volar aspect of the forearm. true or false?

Answer 11

true

Question 12

A Colles fracture describes a dorsally angulated or displaced fracture at what site?

Answer 12

distal radius

Question 13

splintage vs surgical repair of tendons

Answer 13

splintage = achilles

surgical repair = quadriceps, pattellar tendon, sometimes achilles

tendon transfer - tibialis posterior, extensor pollicis longus

Question 14

Acute osteomyeltis, in the absence of previous surgery, is more common in children or adults?

Answer 14

children

Question 15

which movement occurs at the radiocapitallar joint?

Answer 15

supination-pronation of forearm

as do the proximal + distal radioulnar joints

Question 16

what movement is the humero-ulnar joint responsible for?

Answer 16

fleexion/extension

Question 17

which anatomical structure is impinged in hip impingement?

Answer 17

acetabular labrum

Question 18

what movement of the shoulder is restricted in adhesive capsulitis?

Answer 18

external capsulitis
