Document Summary

Anterior compartment: tibia, fibula, interosseous membrane, anterior intermuscular septum, fascia. Deep posterior- can palpate on medial aspect of tibia, transverse intermuscular septum, interosseous membrane. Superficial: transverse intermuscular septum, thick layer of fascia. Tibialis anterior, extensor digitorum longus, extensor hallicus longus. Tibialis posterior, flexor digitorum longus, flexor hallicus longus. Can be devastating to muscle if left untreated. Repetitive overuse may lead to fibrosis and decreased elasticity of fascia. Chronic symptoms arise at predictable point in activity: ex. Compartment fills up with blood, and pressure builds up in compartment- pressure on nerve and vein and they can collapse. Causes bruise bleeding increase volume demands smacked in the shin by field hockey ball. Dumps fluid- fascia doesn"t stretch so keeps building up. Pressure builds thicker arterial walls blood still flows into muscle, but veins are smaller and blood can"t get out of muscle because its compressed. Decrease of oxygenated blood so tissues start to die off.
