The shortness or broadness of the distal segment of the thumb including nail plate was analyzed metrically in a random population consisting of 261 males and 256 females, 4 to 89 years of age. For quantitation of this trait, the racket thumb index was devised. The values of this index increased significantly prior to puberty followed by slight decrease in adult period. The sex and side differences in mean values were not significant in any age groups. The normal range of the index values in adults was between 66.0 and 90.0, and the values under 65.0 were regarded as representative of the racket thumb. The correlation coefficients of racket thumb index were larger in relation to items concerning the length than those pertaining to the breadth.
