Diabetic foot ulcers constitute an increasing health problem in Denmark concurrent with an
ageing population and an increase in diabetes prevalence. Diabetic foot ulcers belong to the
most serious and costly complications. Several studies have found that the size and depth of
the ulcer is one of the major etiologic factors for delayed healing. Wound measurement is
important in the monitoring of the wound healing process. For the last decade different 3D
(three-dimensional) techniques for measuring wounds have been proposed in order to measure
wound volume, but none of the technologies have been widely used. A 3D Wound Assessment
Monitor (WAM) camera has been developed, which is able to measure wound size in 3D and to
assess wound characteristics.
The investigators hypothesize that three-dimensional measurements of diabetic foot ulcers are
feasible in the assessment of wound healing. A prospective cohort study is conducted in which
newly admitted patients with a diabetic foot ulcer are included at the first visit at the
multidisciplinary clinic. The patients are followed for one year or until complete wound
healing, amputation or death. The four wound measurements: 2D area, 3D area, perimeter and
volume are measured using the 3D-WAM camera with frequent intervals. Patient anthropometrics
and wound data are collected during the study and correlated to the wound healing.
