Nerve Entrapment Syndromes of the Foot and Ankle.

Nerve entrapment at the ankle and midfoot is an important, yet frequently underrecognized, source of foot pain. Familiarity with the nerve anatomy and known entrapment sites facilitates evaluation; local nerve lesions in the foot and ankle must be distinguished from proximal nerve dysfunction and systemic diseases that may affect nerve function. Treatment is directed toward reducing contact pressure from footwear and addressing other underlying problems, such as edema and ankle instability that may be contributing to nerve dysfunction.
