| Question | Answer |
| In the hand, which tendons are stronger? | Extensors > flexors |
| What is Allen's test? | A test of radial and ulnar artery hand perfusion, to be performed before an ABG |
| What percentage of people have an ulnar dominant circulation? | 80% |
| How 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) |
| How do you test flexor digitorum profundus only? | Isolate and flex the DIP joint |
| What joint can the extensor digiti minimi tendon be felt at as it crosses? | Distal radio-ulnar joint |
| Which bone is most easily fractured from a FOOSH injury? | Scaphoid (tubercle) |
| What are the thenar muscles? Which nerve controls them? | Abductor pollicis brevis Opponens pollicis Flexor pollicis brevis Median nerve |
| What are the hypothenar muscles? Which nerve controls them? | Abductor digiti minimi Flexor digiti minimi Opponens digiti minimi Ulnar nerve |
| What 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 |
| Which nerve supplies the intrinsic muscles of the hand? | Ulnar |
| Where 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 |
| What 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 |
| What 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) |
| What 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. |
| What 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. |
