What is clinodactyly?

Clinodactyly is a minor bone malformation where your finger curves at the joint closest to your nail and bends toward your other fingers like a hook. It most often affects your fifth digit (pinky finger), but it can happen to any finger or toe. The curve is the result of your finger bone growing in a different shape than it should. It may be present at birth or it may happen as a result of injury to a growing finger in childhood.

It’s normal for fingers to curve at an angle less than 10 degrees. Clinodactyly specifically refers to finger curves at angles greater than 10 degrees.
