Clinodactyly is a medical term describing a bend or curvature of the fifth fingers (the "little fingers") toward the adjacent fourth fingers. It is a fairly common isolated anomaly which often goes unnoticed, but also occurs in combination with other abnormalities in many genetic syndromes, such as Russell-Silver syndrome, Feingold syndrome and in approximately 80%[1] of individuals with Down syndrome. When identified in prenatal ultrasound, it is considered statistically correlated with increased risk of chromosome aberration in the fetus and may be an indication for intrauterine sampling for fetal chromosome analysis. It is also common in Fetal Alcohol Spectrum Disorder.

The term can also be used to describe curled toes. Clinodactyly or congenital curly toes is sometimes seen in the third, fourth or fifth toe and is "fairly common and follows a familial pattern." [2]
