Familial isolated clinodactyly of fingers

Familial isolated clinodactyly of fingers is a condition where one or more fingers curve or bend sideways, most commonly affecting the fifth finger (pinky finger). The word 'clinodactyly' comes from Greek words meaning 'bent finger.' In this familial form, the condition runs in families and occurs on its own — meaning it is not part of a larger syndrome or associated with other birth differences. The curving is caused by an abnormally shaped bone (usually a wedge-shaped middle bone, called the middle phalanx) in the affected finger. The condition is present from birth and is usually noticed in infancy or early childhood as the hands grow. Most people with familial isolated clinodactyly have mild curving that does not cause pain or significant problems with hand function. The degree of bending can vary from barely noticeable to more pronounced. Both hands may be affected, or just one. Because this is an isolated finding, children with this condition typically develop normally in all other ways. Treatment is usually not needed for mild cases. If the curving is severe enough to interfere with hand function or grip, an orthopedic hand surgeon may recommend corrective surgery. Physical or occupational therapy may also be helpful in some cases. Overall, this is considered a benign condition with an excellent outlook, and most people live completely normal lives without any limitations.
