Superficial Peroneal Neuropathy Associated with Cavus Foot: A Case Report |

Abstract |
Cavus foot is a deformity marked by an abnormally high medial longitudinal arch. It may be an inherited condition (accompanying Charcot-Marie-Tooth disease or congenital clubfoot), part of a central nervous system (CNS) disorder (ie, cerebral palsy, poliomyelitis), or the result of traumatic injury. There is usually an antecedent neuropathy. Hindfoot varus and forefoot valgus are ultimately produced, inciting foot pain and lateral ankle instability. Long-term complications of cavus foot are metatarsalgia, fifth metatarsal stress fracture, plantar fasciitis, and iliotibial band syndrome. Peripheral neuropathy due to cavus foot is uncommon. In fact, no instances of peripheral neuropathy stemming from long-term cavus foot have been reported to date. Described herein is the first documented case of superficial peroneal neuropathy in conjunction with cavus foot. Importantly, this neuropathy may be improved by correcting the cavus foot deformity. |
