Purpose: Although monitoring intracompartmental pressure under a cast is very important, it is not possible to measure it in every patient undergoing cast treatment. This study aims to answer the question, whether skin surface pressure under a cast can reveal intracompartmental pressure. Material and Methods: A plaster cast was applied to a sculpted inflatable forearm model with dorsal and volar compartments. Skin surface pressures under the cast were measured at five different localizations from both dorsal and volar sides of the model and compared to corresponding intracompartmental pressures. Results: All of the skin surface pressure measurements taken from the dorsal and volar side of the model correlated with intracompartmental pressure. Mean correlation coefficient of the measurements was .995 (P=.000), (Std dev: .002, Minimum .992, Maksimum .999). Conclusion: Measuring the pressure between skin and cast can monitor intracompartmental pressure. Skin surface pressure monitoring can help the physician, patient or parents in the follow up of patients undergoing cast treatment.
