Technique of Davey et al. for decompression of leg compartments. A, Lateral skin incision from fibular neck to 3 to 4 cm proximal to lateral malleolus. B, Skin is undermined anteriorly, and fasciotomy of anterior and lateral compartments is performed. C, Skin is undermined posteriorly, and fasciotomy of superficial posterior compartment is performed. D, Interval between superficial posterior and lateral compartments is developed. Flexor hallucis longus muscle is dissected subperiosteally off fibula and retracted posteromedially. Fascial attachment of tibialis posterior muscle to fibula is incised to decompress muscle.
