Shortly after the injury process, a swelling of the soft skin tissue in the fracture area is formed, often preventing an immediate operation of the fracture. Our work aims for reducing the swelling and to accelerate the swelling decline. This is achieved by considering the spatial distribution of inflammation and applying mild local hyperthermia. Therefore it is necessary to investigate how the inflammation has spread out nearby the fracture tissue. In order to locate the focus of inflammation, a time-dependent monitoring with a temperature sensor mat is necessary. Temperature sensors should be arranged in a netlike style in order to measure a skin area as large as possible under the support bandage. The spatially optimal necessary distance between the sensors is determined by analyzing and evaluating temperature gradients on infrared images of ankle fractures.
