Analysis of Pre- and Postexercise Compartment Pressures in the Medial Compartment of the Foot

Abstract

Growing awareness of chronic exertional compartment syndrome of the foot has led to the need for site-specific analysis of normative resting and postexertional intracompartment pressures. Thirty-four asymptomatic athletes underwent pressure testing of the medial foot compartment with an intracompartmental pressure measurement apparatus. Pressure measurements were recorded before exercise and after 20 minutes of running. Mean resting intracompartment pressure was 7.7 mm Hg, whereas mean pressures 1 and 5 minutes after exercise were 19.1 mm Hg and 10.7 mm Hg, respectively. These data were then compared with data from compartment pressure studies performed in nine symptomatic subjects, each with a clinical history suggestive of chronic exertional compartment syndrome of the medial foot compartment. The results demonstrated normative compartment pressures of the medial foot compartment are comparable with previously measured pressures of the leg. This study shows that previously defined criteria for diagnosis of chronic exertional compartment syndrome of the leg may also be used for diagnosis of chronic exertional compartment syndrome of the foot.
