Compartment syndrome of lower leg associated with undisplaced fibula fracture

Acute limb compartment syndrome is a condition in which raised pressure within a closed fascial space reduces capillary perfusion below a level necessary for tissue viability. When recognised, treatment is urgent surgical decompression of the fascial compartments of the affected limb. We present a case of unusual presentation of a patient with acute compartment syndrome of the lower leg treated with urgent fasciotomy after sustaining a seemingly trivial injury associated with an undisplaced fracture of the fibula.
