1. What in the configuration of the anterior compartment makes this region particularly liable to an increase in intracompartmental pressure?

2. How would you test for involvement of the deep peroneal nerve, keeping in mind that dorsiflexion of foot and toes may be severely interfered with by anoxia (lack of oxygen) of the muscles in the compartment, and that loss of muscle action therefore does not necessarily imply nerve involvement?

3. What area of the skin would you test for sensory loss?

4. The presence of arterial pulse in the anterior tibial and dorsalis pedis arteries seems to prove patency of the main stem, although, occasionally, a well-established collateral circulation in the lower part of the leg by means of branches from the arteries in the posterior compartment may simulate patency in a vessel blocked higher up.
