Diagnosis which affects all compartments of the hand; was made on clinical grounds in two patients (the intra- localized, which affects only a group of com- compartmental pressure was not measured) and after clin- partments, mostly referring to the radial- ical examination plus measurement of intracompartmen- tal pressure in nine patients.
