main-en-lorgnette deformity

A classic descriptor for a hand afflicted by arthritis mutilans—severe rheumatoid arthritis—which is accompanied by extensive compressive erosion, collapse of the proximal phalanges with ‘telescoping’ of bones on themselves and overriding of fingers by metacarpophalangeal dislocation, resulting in destroyed contracted hands; although typical of advanced rheumatoid arthritis, this deformity may occur in psoriatic arthritis, erosive osteoarthritis, chronic infection, diabetes, and leprosy
