Description: Clinodactyly is described as an angulation at an interphalangeal joint in the radio-ulnar or palmar planes. Burke (8), in a useful paper, stresses that clinodactyly is a physical sign and not a disease. It is caused by various alterations in growth of the phalanx proximal to the angulation. One significant problem is what degree of angulation justifies the diagnosis. Minor degrees of curvature of the small finger are so common as to be considered normal; at least I certainly think so since both of my small fingers show at least 10 degrees of radial inclination
Camptodactyly is a nontraumatic flexion contracture of the proximal interphalangeal joint of the little finger with occasional additional involvement of one or more adjacent fingers. It usually occurs sporadically but when familial has a dominant autosomal pattern.
