Fichas del conjunto (16)
- 1In the hand, which tendons are stronger?Extensors > flexors
- 2What is Allen's test?A test of radial and ulnar artery hand perfusion, to be performed before an ABG
- 3What percentage of people have an ulnar dominant circulation?80%
- 4How many veins are there for every artery in the hand? What does each digital artery supply?2
A space in between the fingers (ie half of each finger it is in between) - 5How do you test flexor digitorum profundus only?Isolate and flex the DIP joint
- 6What joint can the extensor digiti minimi tendon be felt at as it crosses?Distal radio-ulnar joint
- 7Which bone is most easily fractured from a FOOSH injury?Scaphoid (tubercle)
- 8What are the thenar muscles? Which nerve controls them?Abductor pollicis brevis
Opponens pollicis
Flexor pollicis brevis
Median nerve - 9What are the hypothenar muscles? Which nerve controls them?Abductor digiti minimi
Flexor digiti minimi
Opponens digiti minimi
Ulnar nerve - 10What does a swelling on A) the volar surface of a finger B) the 1st extensor compartment C) the extensor tendons at the wrist D) carpal tunnel E) joints i) base of thumb ii) PIPJ iii) DIPJ iv) MCPJs indicate?A) Tenosynovitis or Infection of the flexor tendon sheath
B) De Quervain's tenosynovitis
C) RA, synovitis
D) RA flexor tenosynovitis
E)i) RA, OA
ii) Bouchard's nodes RA, gout
iii) Heberden's nodes OA
iv) RA - 11Which nerve supplies the intrinsic muscles of the hand?Ulnar
- 12Where is the area for sensation testing A) the radial nerve B) the median nerve C) the ulnar nerve?A) 1st dorsal web space
B) tip of index finger
C) tip of little finger - 13What is the movement for muscle testing a) the radial nerve b) the median nerve c) the ulnar nerve?A) Resist wrist extensors
B) Resist thumb abduction
C) Resist index finger abduction - 14What is Tinel's test? Where is a) the median nerve and b) the ulnar nerve tested?A test for nerve irritation e.g. carpal tunnel syndrome. Involves tapping from distal to proximal along the path of the nerve, a positive result is induction of tingling/numbness.
A) At the carpal tunnel
B) Guyon's canal (path of ulnar nerve at wrist) and cubital tunnel (elbow) - 15What is Phalen's test?A test for carpal tunnel syndrome involving passing flexion of both wrists for 2 minutes. A positive result is induction of tingling/numbness.
- 16What is Finkelstein's test?For De Quervain's tenosynovitis
Involves stretching abductor pollicis longus and extensor pollicis brevis by sharply ulnar deviating the hand - a positive result is a sharp pain along the distal radius.
