Clinodactyly is a medical term describing the curvature of a digit (a finger or toe) in the plane of the palm, most commonly the fifth finger (the “little finger”) towards the adjacent fourth finger (the “ring finger”).
It is a fairly common isolated anomaly which often goes unnoticed, but also occurs in combination with other abnormalities in certain genetic syndromes.[1] The term is from the Ancient Greek κλίνειν klínein ‘to bend’ and δάκτυλος dáktulos ‘digit’.
