What kind of nail abnormalities do you look for, in the hand examination, which usually indicate PsA and maybe RA?
Pitting: Small pits/dents in nail
Onycholysis: Nail separates from skin
Ridging: Vertical raised lines on nails
Colour change to yellow or brown
Clubbing
Apart from nail changes, what abnormality can appear near the nails?

Could be due to pseudogout
What 2 types of abnormal nodes can you look for at the PIP and DIP joints of the hand, and what is the underlying pathology?
Bouchard’s nodes: Bony growths at PIP
Heberden’s nodes: Bony growths DIP
Both indicate OA
What 3 fixed flexion deformities of the fingers can you look for, and what condition do they indicate?
Swan neck deformity: DIP flexion, PIP hyperextension which suggests RA
Boutonniere’s deformity: DIP hyperextension, PIP flexion which suggests RA
Dupuytren’s contracture: Fibrous cord crosses and contracts MCP then PIP
What fixed flexion deformity of the thumb can you look for, and what condition does it indicate?
Z-thumb: interphalangeal joint hyperextension, fixed flexion and subluxation of metacarpophalangeal joint
Suggests RA
What abnormality in the thumb can you look for, that suggests OA?

Vertical red-brown line under nail
suggests local trauma, infective endocarditis, sepsis, vasculitis and psoriatic nail disease
What is Dupuytren’s contracture, and which fingers are most commonly affected?
Thickening of the plantar fibrous tissue forms fibrous cords, which cross MCP then PIP and cause them to contract

Dupuytren’s contracture
Hypothenar and thenar muscle wasting
Osler node: red-purple slightly raised tender lumps with pale centre on fingers, suggest infective endocarditis
