Answer

The surgical procedure can include part or all of a longitudinal straight or S-shaped incision on the dorsum of the foot, starting between the bases of the first and second metatarsals and extending proximally to the anterior ankle, depending on the predicted location of entrapment.

The deep fascia overlying the deep peroneal nerve and the dorsalis pedis artery is released, as is the inferior part of the extensor retinaculum; the superior part can be preserved to maintain the function of the extensor tendons. The deep peroneal nerve is followed proximally and distally to verify a full release. Nerves that appear to be normal in consistency and size can be released. [69]

It is important to treat other underlying causes of entrapment or stretch (eg, complete excision of underlying osteophytes during surgery). The decision to perform neurolysis as opposed to excision, transposition, or both is dependent on the severity of injury to the nerve.
