presents as a thickening or painless nodule in the palm

the most common finger to be affected in the ring finger

in advanced disease, there is a loss of range of motion in the affected fingers

52
Q

Why are the elbows and thenar/hypothenar eminence looked at on the palms?

A

the temperature of the wrists and small joints of the hand is assessed and compared

increased warmth in a joint is suggestive of inflammatory arthritis or joint sepsis

55
Q

Why is the radial and ulnar pulse palpated when feeling the palm?

A

to confirm that there is adequate blood supply to the hand

56
Q

Why is the muscle bulk of the thenar/hypothenar eminence assessed when feeling the palm?

A

wasting of these areas is often noted in ulnar/median nerve lesions

57
Q

Why are the palms palpated when feeling the hand?

A

to look for evidence of palmar thickening

this is caused by Dupuytren’s contracture

58
Q

How is median and ulnar nerve sensation assessed in the feel stage of the hand examination?

A

median nerve sensation:

assessed over the thenar eminence and index finger

ulnar nerve sensation:

A

palpate the patient’s arm along the ulnar border to the elbow

note any rheumatoid nodules or psoriatic plaques

66
Q

What is the general rule for joint movement during the move stage of the hand exam?

each movement is assessed actively first - the patient does the movements independently

the movement is then assessed passively, feeling for crepitus and noting any pain

67

it can be useful in diagnosis of carpal tunnel syndrome

79
Q

What are the stages in Tinel’s test?

A
  1. tap over the carpal tunnel with your finger
  2. if the patient develops tingling in the thumb and radial 2 1/2 fingers, this is suggestive of medial nerve compression and irritation
80
Q

When is Phalen’s test used?

A

if history or examination findings are suggestive of carpal tunnel syndrome, Phalen’s test further supports the diagnosis

81
Q

How is Phalen’s test conducted?

  2. if the patient’s symptoms of carpal tunnel syndrome are reproduced, then the test is positive
    (e. g. burning, tingling, numb sensation in the thumb, index, middle and ring fingers)
