The deep fascia of the leg is continuous above with the deep fascia of the thigh. It envelops the leg and fuses with the periosteum of the tibia at the anterior and medial borders. Other fascial septa, and the interosseous membrane, divide the leg into four compartments: extensor, peroneal, superficial and deep flexor.
Following fractures of the leg, oedema within one or more compartments can lead to obstruction to blood flow with consequent infarction of tissue—the 'compartment syndrome'. When this occurs immediate decompression (fasciotomy) of all four compartments is necessary.
