Compartments in the Lower Leg Med Lat Med Lat R
Objectives Use a common trauma injury case to… • Understand the basic pathophysiology of compartment syndrome • Focus on the neurovasculature of the anterior compartment • Walk through the treatment guided by anatomical landmarks
Review the Qs • What’s the major artery passing through the anterior compartment that eventually becomes the dorsalidpedis? • The Common Peroneal nerve gives off what branch in the Lateral compartment and what branch in the Anterior compartment? • CS of the anterior compartment presents as numbness or tingling where? • Foot drop occurs with damage to the deep peroneal because which muscle is affected?

Things to Know • Vasculature • Anterior tibial artery is the blood supply for this compartment…terminal branch of popliteal artery…passes anteriorly through gap in superior part of interosseous membrane, at malleoli Becomes dorsal artery of foot • The posterior tibial artery and its biggest branch the fibular artery supply the posterior compartment. • Know nerves • Deep peroneal - Extends in to foot to supply extensor digitorum brevis and extensor hallicus brevis and skin b/ 1st and 2nd toes • Goes to tibialis anterior dorsiflexes foot drop
