Angiosomal Interpretation of Dermal Thermometry in Diabetic Foot Patients

This research article presents findings on the angiosomal interpretation of dermal thermometry in patients at high risk for diabetic foot ulcers (DFUs). The study aims to enhance limb preservation strategies by utilizing remote temperature monitoring to detect inflammation that may precede ulcer formation. It involves daily temperature measurements at six key-point locations on the foot and examines the correlation of temperature asymmetries with the angiosome model. A multi-center trial followed 129 participants over 34 weeks, collecting data on DFU occurrences and high-resolution thermograms. The results indicate that the heel is thermally isolated from the forefoot, while specific metatarsal locations show varying degrees of involvement. The study concludes that wireless technology can effectively detect temperature differences, potentially guiding early interventions to prevent ulcer recurrence. However, it notes that the relationship between inflammation and the angiosome model requires further exploration.
