Hand and Wrist Examination Flashcards
What position should the patient be in before commencing a hand and wrist examination?
● Adequately expose the patient’s hands, wrist and elbows.
● Position the patient seated with their hands on a pillow.
● Ask the patient if they have any pain before proceeding with the clinical examination.
What is the first step in a hand and wrist examination?
● General inspection looking for clinical signs and objects/equipment.
What clinical signs should you be aware of when performing a general inspection?
● Scars
● Wasting of muscles
What may scars be suggestive of when completing a general inspection during a hand and wrist exam?
● May provide clues regarding previous upper limb surgery.
What may wasting of muscles be suggestive of when completing a general inspection during a hand and wrist exam?
● Suggestive of disuse atrophy secondary to joint pathology or a lower motor neuron lesion.
What objects or equipment may be seen when performing a general inspection during a hand and wrist exam?
● Aids and adaptations - e.g. splints
● Prescriptions
What areas of the hands should be inspected during a hand and wrist exam?
● Dorsal aspect of the hand
● Palmar aspect of the hand
List some clinical signs that may be observed on the dorsal aspect of the hand when completing a hand and wrist exam?
● Hand posture
● Scars
● Swelling
● Skin colour changes
● Bouchard’s nodes
● Heberden’s nodes
● Swan neck deformity
● Z-thumb
● Boutonnières deformity
● Skin thinning or bruising
● Psoriatic plaques
● Muscle wasting
● Splinter haemorrhages
● Nail pitting and onycholysis
What may an abnormal hand posture be suggestive of when completing a hand and wrist exam?
● May indicate underlying pathology (e.g. Dupuytren’s contracture, ulnar deviation secondary to rheumatoid arthritis).
What may scars be suggestive of when completing a hand and wrist exam?
● May indicate previous surgery or trauma.
What may Bouchard’s nodes be suggestive of when completing a hand and wrist exam?
● Occur at the proximal interphalangeal joints (PIPJ) and are associated with osteoarthritis.
What may Heberden’s nodes be suggestive of when completing a hand and wrist exam?
● Occur at the distal interphalangeal joints (DIPJ) and are associated with osteoarthritis.
What may swan neck deformity be suggestive of when completing a hand and wrist exam?
● Occurs at the distal interphalangeal joint (DIPJ) with clinical features including DIPJ flexion with PIPJ hyperextension.
● Swan neck deformity is typically associated with rheumatoid arthritis.
What may Z-thumb be suggestive of when completing a hand and wrist exam?
● Hyperextension of the interphalangeal joint, in addition to fixed flexion and subluxation of the metacarpophalangeal joint (MCPJ).
● Z-thumb is associated with rheumatoid arthritis.
What may Boutonnières deformity be suggestive of when completing a hand and wrist exam?
● PIPJ flexion with DIPJ hyperextension associated with rheumatoid arthritis.
What may skin thinning or bruising be suggestive of when completing a hand and wrist exam?
● Can be associated with long-term steroid use (e.g. common in patients with active inflammatory arthritis).
What may psoriatic plaques be suggestive of when completing a hand and wrist exam?
● Salmon coloured plaques with a silvery scale. Patients who have psoriasis are at significantly increased risk of developing psoriatic arthritis.
What may muscle wasting be suggestive of when completing a hand and wrist exam?
● Can occur secondary to chronic joint pathology or lower motor neuron lesions (e.g. median nerve damage secondary to carpal tunnel syndrome).
What may splinter haemorrhages be suggestive of when completing a hand and wrist exam?
● A longitudinal, red-brown haemorrhage under a nail that looks like a wood splinter.
● Causes include local trauma, infective endocarditis, sepsis, vasculitis and psoriatic nail disease.
What may nail pitting and onycholysis be suggestive of when completing a hand and wrist exam?
● Associated with psoriasis and psoriatic arthritis.
What may skin colour changes be suggestive of when completing a hand and wrist exam?
● Erythema of the soft tissue may indicate cellulitis or joint sepsis
List some clinical signs that may be observed on the palmar aspect of the of the hand when completing a hand and wrist exam?
● Hand posture changes
● Scars
● Swelling
● Dupuytren’s contracture
● Thenar / hypothenar wasting
● Psoriatic plaques (elbow)
● Rheumatoid nodules (elbow)
● Janeway lesions
● Osler’s nodes
What may (hypo-)thenar wasting be suggestive of when completing a hand and wrist exam?
● Isolated wasting of the thenar eminence is suggestive of median nerve damage (e.g. carpal tunnel syndrome).
What may Janeway lesions be suggestive of when completing a hand and wrist exam?
● Non-tender, haemorrhagic lesions that occur on the thenar and hypothenar eminences of the palms (and soles). Janeway lesions are typically associated with infective endocarditis.
What may Osler’s nodes be suggestive of when completing a hand and wrist exam?
● Red-purple, slightly raised, tender lumps, often with a pale centre, typically found on the fingers or toes. They are typically associated with infective endocarditis.
What aspects of the hands should you feel when the palms are up in a hand and wrist exam?
● Temperature
● Radial and ulnar pulse
● Thenar and hypothenar eminence bulk
● Palmar thickening
● Median and ulnar nerve sensation
What aspects of the hands should you feel when the palms are down in a hand and wrist exam?
● Radial nerve sensation
● Temperature
● Metacarpophalangeal joint squeeze
● Bimanual joint palpation
● Anatomical snuffbox
● Bimanual wrist palpation
Describe how you would assess temperature during a hand and wrist exam?
● Assess and compare the temperature of the joints of the hand and elbow using the back of your hands.
● Assess and compare the temperature of the joints on the dorsal aspect of the hand (e.g. metacarpophalangeal joints) and elbow using the back of your hands.
