Dynamics of the anterior crural compartment during muscle contraction

The anterior crural compartment is a closed space, prone to developing compartment syndrome. The aim of research is to determine flexibility of the anterior crural space and possibility of this space to answer to dynamical changes of muscles volume. Ultrasound diagnostic is very helpful method in observing changes whitin the anterior crural compartment in real time. The study included 100 examinees. Using linear ultra-sound probe of 7.5 MHz transversal scan of anterior crural compartment have been made at three levels: in the neutral position of the foot, as well as in maximal dorsal and plantar flexion. In the position of maximal dorsal flexion (contraction of the anterior crural muscles), surface of the proximal cross-section is increasing for 26, 86 %, whereas middle and distal surfaces decreases. The volume of this space is being increased during maximal dorsal flexsion of the foot average for 4, 13 %. Also during contraction of posterior crural muscles the volume of anterior crural compartment is being increased average for 1, 13 %. In case of dorsiflexion, the muscles of anterior crural compartment move toward the proximal end, and in case of plantar flexion, possible compressed with posterior crural muscles, toward distal end. However, the space of the anterior crural compartment increases its volume in extreme positions of the foot and thus follows, in phisyological conditions, dynamical changes of muscle masses.
