Abstract

Time line of wound healing and prediction of healing times in diabetic foot ulcers is an important issue. Usually, the percentage of wounds healed within a defined period is used for characterization of wound healing. R=sqrtA/pi (R, radius; A, planimetric wound area; pi, constant 3.14), and the wound radius reduction was 0.39 mm/week which was previously established. The initial average wound area was 96.9+/-13.1 mm2 (mean+/-SEM), and 3.61+/-1.6 mm 2 after ten weeks with an average healing time of 75.9 (95 %-CI 71-81) days. Using the equation mentioned above and the calculated weekly wound radius reduction, the predicted healing time in the test group was 86.9 (95 %-CI 73-101) days. The predicted and the observed healing times were significantly correlated with each other (r=0.55, p=0.0002). Providing standard care, the time needed for wound healing can reliably be predicted in neuropathic diabetic foot ulcers. This may be a useful tool in daily clinical practice to predict wound healing and recognize ulcers who do not respond adequately to the treatment.
