Three‐dimensional documentation of wound healing: First results of a new objective method for measurement

Summary Background: The objective assessment of wound healing is one essential parameter of quality assurance in a modern chronic wound management program. In the past assessment has been based exclusively on a two-dimensional measurement of the wound surface with planimetry or digital photo documentation in combination with such measurements. An objective method for measuring the volume of chronic wounds has not yet been available. Patients and Methods: In cooperation with the company RSI, we linked digital photography, optical raster by means of digital scanner, and picture processing software (DigiSkin®) for an exact three-dimensional image of chronic wounds. The generated point clouds allow the visual, computer-assisted three-dimensional quantification and can document the course of healing of chronic wounds. Results: In comparison to currently available systems, our new method makes possible the objective measurement of volume changes and wound healing course in chronic wounds.We demonstrate the utility of the system in reference to three patients with chronic venous leg ulcers. Conclusions: Using this new, objective three-dimensional wound measurement system,it is possible to reliably quantify changes in wound healing for the first time. Future clinical studies have a new option for the gathering of data which will facilitate evidenced-based conclusions.
