Is there an anatomical marker for the deep peroneal nerve in midfoot surgical approaches?



The deep peroneal nerve (DPN) passes over the dorsum of the foot and is susceptible to injury during surgical approaches. The purpose of this anatomical study is to examine the relationship of the extensor hallucis brevis (EHB) as it passes over the DPN. Ten cadaver feet specimens were dissected and the anatomical structures surrounding the neurovascular bundle containing the DPN were examined. In nine out of the ten specimens the DPN was under the EHB musculotendinous junction. In one case it passed through the musculotendinous junction. This cadaver study has found a consistent easily identifiable landmark for protecting the neurovascular bundle containing the DPN during dorsal midfoot surgery. Clin.
