Answer

A significantly more distal point of tenderness suggests a more distal piercing of the intermediate dorsal cutaneous nerve through the fascia, in which case two separate incisions may be made. Blunt subcutaneous dissection is done, and the nerve is found emerging through the fascia. A local fasciotomy is performed, releasing the nerve proximally and distally until it is completely free. In the setting of chronic compartment syndrome, a complete fasciotomy may be considered; however, the ensuing peroneal muscle weakness may affect athletic performance.
