title: Using ulcer surface area and volume to document wound size.
abstract: The evaluation of ulcer size is normally limited to measuring length, width, and depth, and comparing those figures to previously obtained values. These comparisons are grossly inaccurate, and a more representative technique can be used by treating the ulceration as a three-dimensional object. The author proposes several mathematical formulae that are easily computed on a hand-held calculator. The formulae use the measurements of length, width, and depth, and translate those dimensions into surface area and volume.
