Hand surface area--do racial differences exist?

The patient's 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 patient's 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.

Burns area estimation-an error perpetuated.

In estimating small areas of burns, it is traditionally taught that the patient's palm is 1% of the body surface area. Whether the palm means the palmar surface of the whole hand or palm excluding the fingers, has not been very clear and is a source of confusion to many junior doctors. The ATLS teaching has been in contradiction to the evidence from literature and hence we undertook a study to examine the evidence and practices regarding this issue.
