Bilateral camptodactyly

Greek for "camptodactyly" is "bent finger," and Smith and Kaplan´s exhaustive review lists all of its numerous synonyms (1968). It refers to a non-traumatic flexion contracture of the proximal interphalangeal joint, typically of the little finger, in surgical practise. A post-traumatic aetiology rather than camptodactyly is suggested by involvement of the distal interphalangeal joint or the metacarpo-phalangeal joint. Prevalence less than 1%. It can be unilateral (33%) or bilateral (66%), if bilateral, can be symmetric or asymmetric. Camptodactyly should not be confused with clinodactyly or Kirner´s deformity.
