Knighton et al evaluated chronic nonhealing wounds using the Total Wound Score, which consists of 3 parts. The authors are from the University of Minnesota in Minneapolis.
Patient selection: chronic nonhealing wound from mixed etiologies
Parameters for wound measurements:
(1) size in square centimeters
(2) depth in mm
(3) undermining mm
(4) duration in months or years

where:
• In the original table there is not a category for none in undermining. This would mean that the minimum score should be 3. However, the text says that the minimum overall score is 0.
total general subscore =
= SUM(points for all 4 parameters)
Interpretation:
• minimum subscore: 0
• maximum subscore: 38
• The higher the score the more severe the wound.
