Broad finger

What it means

Increased width of a non-thumb digit of the hand.

Note that the girth may be increased in a broad finger, but this must be distinguished from Macrodactyly, because there the length is also increased. This distinction can be subtle. This term should not be used when the increased width is limited to the distal phalanges, instead use Broad fingertips. The affected digit should be specified by the numbering scheme in the introduction. This term is not used for the first digit, see Broad thumbs. When a thumb and one or more fingers are affected, it may be more economical to specify "Broad fingers, F1-5" instead of separately specifying "Broad thumb" and "Broad fingers F2-5".
