Inward curving of the fifth finger is associated with Down syndrome; what is the term for this finding?

Explanation:
Clinodactyly describes inward bending of a finger, most commonly the little finger curving toward the adjacent finger. In Down syndrome, this curvature often results from abnormal development of the middle phalanx (a delta phalanx) that tilts and causes angular deviation. This distinguishes it from other terms: syndactyly is fusion of digits, polydactyly is extra digits, and camptodactyly is a fixed flexion deformity at the finger joint.
