In 10 cases, the authors describe the musculo-cutaneous nerve syndrome in the foot. It involves pain and paresthesias located on the dorsal aspect of the foot, occurring after local trauma or repeated microtraumas (ill fitted shoes), promoted by a static disorder (anterior hollow foot, calcaneal valgus). The diagnosis is essentially clinical, based on the presence of a Tinel sign on the dorsum of the foot and on the infiltration test. The treatment consists in the combination of local measures and steroid infiltration. Neurolysis is only indicated in case of failure of the medical treatment (4 cases). Then, it always proves to be effective.
