A compression injury of the peroneal nerve, deep in the anterior compartment of the lower leg. It occasionally occurs in a normally sedentary person who performs a very intensive burst of activity. It may also occur after serious bruising of the shin or after a fracture. Symptoms include throbbing and paraesthesia (e.g. an abnormal tingling sensation) followed by anaesthesia (lack of sensation) in the web between the first and second toes. Treatment includes ice and elevation. Surgical decompression may be required if motor weakness develops, or if the tissues within the compartment are compromised (see compression syndrome).
