Sims et al described preulceration of the plantar surface of the foot in a diabetic. This can help to identify a patient who may benefit from an intervention to reduce plantar injury. The authors are from Pennsylvania State University.


Patient selection: diabetic

An undesirable change consist of one or more of the following:

(1) higher temperature (>= 2°C) than the contralateral foot that cannot be explained by recent physical activity or heat exposure

(2) intraepidermal maceration (boggy texture due to extravasation of fluid)

(3) hematoma with or without overlying callus
