Abstract:
The projection area of the volar surface of the human hand was estimated on 52 young Chinese adults(26 males and 26 females.)ranging in age from 18 to 31. The average projection area of the volar surface of the hand was 145.20 square centimetres.It occupied 0.93％ of the calculated body surface.The area of the palm was 86.69 square centimetres, amounting to 59.70％ of the volar surface of the whole hand. All dimensions of different parts of the hand of males were larger than those of females. There was no difference between the right and left hands of both sexes. The coefficient of correlation among the body length, body weight, length and width of the hand, surface area of the whole body with the projection area of the volar surface of the hand was calculated. All showed close correlation. The regression of the estimation of the projection area of the volar surface of the hand with hand length and hand width was established. It is therefore to be assumed that the area of the volar surface of the hand calculated as one per cent of the body area, as it is often used in surgical examina- tions, seems to be a little higher than its real area(0.93％.
