Measurement of tissue hardness: can this be a method of diagnosing compartment syndrome noninvasively in children?

In order to assess the feasibility of using the measurement of tissue hardness as a method of diagnosing compartment syndrome noninvasively in children, a simple hand-held device to measure tissue hardness was fabricated. The relationship between hardness and compartmental pressure was studied in an experimental model and in three fresh amputated lower limbs. Normal tissue hardness of the forearm was measured in 189 children and 20 adults to identify the factors that influence normal tissue hardness.
