Hand surface area—Do racial differences exist?

The patientʹs own palm is used as a template in assessing small patchy burns and is traditionally believed to be 1% of body surface area. This does alter with the patientʹs age, sex and BMI and there have been suggestions that it can also differ between ethnic groups. We undertook this study to see if there were any differences in the hand surface area between Caucasians, Orientals and Asians. It was done by tracing the hand outline and calculating the surface area. The study showed that there was no significant difference between the three ethnic groups in terms of hand surface area.
