camptodactyly of fingers
Camptodactyly of fingers is a rare, genetic, non-syndromic, congenital limb malformation characterized by a painless, non-traumatic, non-neurogenic, often bilateral, permanent flexion contracture at the proximal interphalangeal joint of a postaxial finger, resulting in permanent volar inclination of the affected digit. The fifth finger is always involved, but additional digits might also be affected.
