Fasciotomy of the foot

Two dorsal longitudinal incisions are made to access the foot compartments. The incisions are positioned medial to the second metatarsal shaft and lateral to the fourth metatarsal shaft. Each of the four sub-compartments of the interosseous compartment (turquoise) are opened between the metatarsal bones through the dorsal incisions. The calcaneal compartment (purple), which lies beneath the metatarsals, is opened directly. The lateral compartment (green) is decompressed through the lateral dorsal incision. The medial compartment (red) may be accessed by dissecting medial to the second metatarsal. Alternatively, the medial compartment can be accessed through another incision along the medial foot, immediately posterior to the first metatarsal.
