Camptodactyly is a medical condition involving fixed flexion deformity of the interphalangeal joints of the little finger. This involves permanent flexure of one or more phalanges (fingers). Camptodactyly is an autosomal dominant trait that is known for its incomplete expressivity as it can occur in both little fingers, one, or neither.
The name is derived from the ancient Greek words kamptos (bent) and daktylos (finger).
A number of congenital syndromes may cause camptodactyly:

The common treatment is splinting and occupation therapy. Surgery is the last option for most cases as the result may not be satisfactory.
