Medial branch of deep fibular nerve block for leg cramps―a case series

Abstract

Nocturnal leg cramps are happened commonly in calves. They often recur and have difficulty to be treated. While the effectiveness of the medial branch of the deep fibular nerve block is reported for leg cramps, it has not been reported in pain clinic diseases. In the current study, four pain clinic cases were evaluated. In three cases, the cramps occurred in the gastrocnemius muscle, and another in the tibialis anterior muscle. The duration was about two weeks or more. Although the mechanism of the medial branch of the deep fibular nerve block is unclear, it could be a very minimally invasive, convenient and satisfactory treatment for nocturnal leg cramps.
