Elbow

Question 1

middle radioulnar articulation

Answer 1

interosseous membrane and radius and ulna

Question 2

inerosseous membrane

Answer 2

prevents proximal displacement of the radius on the ulna. Displacement likely occur with pushing movement

Question 3

Oblique cord prevents

Answer 3

prevents displacement of the radius on the ulna, especially during movements involving pulling

Question 4

normal carrying angle

Answer 4

5-10 for men

10-15 for women

Question 5

Gun stock deformity

Answer 5

15 degree medial deviation due to fracture or epiphyseal injury to the distal humerus and a cubitus varus

Question 6

triangular area of elbow

Answer 6

radial head, tip of olecranon, lateral epicondyle

Question 7

Lateral epicondylitis method 3 test sometime is called

Answer 7

Maudley’s test

Question 8

test for pinch grip test and Froment sign

Answer 8

Positive can not pinch with tips of index and thumb. Median injury. Froment sign is opposite. Ulnar injury

Question 9

Ligament of struthers is called

Answer 9

humerus supracondylar process syndrome
abnormal spur on the shaft of the humerous to the medial epicondyle of the humerus. Brachial artery also accompanies the nerve through this tunnel. Neurological symptom affects pronator teres and same as pronator teres syndrome. Motor loss and sensory loss. Sensory first, motor affects later, with wrist and finger flexion as well as thumb movement being most affected

Question 10

Pronator teres syndrome

Answer 10

Median compressed between two heads of Pronator teres. Pronation is possible but weakness is evident as pronation is loaded

Question 11

anterior interosseous nerve syndrome is called

Answer 11

Kiloh-Nevin syndrome, no sensory loss, but pinch sign is positive

Question 12

Ulnar nerve

Answer 12

C7-C8, T1, cubital tunnel is 2nd common entrapment, affects flexor carp ulnaris and ulnar half of the flexor digitorum profundus

Question 13

Posterior interosseous syndrome

Answer 13

C5-C8, T1
Posteiror interosseous nerve, compressed between two heads of supinator in the arcade or canal of Frohse. Functional involvement of extensors, wrist drop, no sensory deficit

Question 14

Radial tunnel syndrome

Answer 14

mimic tennis elbow. Compress Radial nn at entrance to the tunnel anterior to the head of the radius, near the nerve supplies brachioradialis and extensor carpi radialis longus, beween the ulnar half of the tendon of extensor carpi radialis brevis and its fascia and distal border of supinator

Question 15

Cheiralgia paresthetica

Answer 15

aka wartenberg disease/sign

Compression of radial nerve at brachioradialis tendon, nocturnal pain along the dorsum of the wrist, thumb and web space

Question 16

cubital tunnel

Answer 16

made up with ulnar collateral ligament with FCU, ulnar nerve passes through and causes tardy ulnar palsy
