The muscular branching characteristics of the deep peroneal nerve in adult human cadavers

The aim of this study was to investigate the number of muscular branches and muscular branching characteristicsof the deep peroneal nerve to the muscles. In this study, a total of 16 lower extremities from 8 male cadavers fixed withformalin, ethanol, and glycerol solution were dissected and the number of muscular branches of the deep peroneal nerveand muscular branching features were investigated. It was observed that 31.5% of the muscular branches given by the deepperoneal nerve came to the tibialis anterior muscle, 28.9% to the extensor digitorum longus muscle, 25.5% to the extensorhallucis longus muscle, 11.4% to the peroneus tertius muscle and 2.7% to the peroneus longus muscle. Muscular branches tothe tibialis anterior muscle, extensor digitorum longus muscle, and peroneus tertius muscle were generally originated fromthe deep peroneal nerve in the proximal 1/3 of the leg. Muscular branches to the extensor hallucis longus muscle arose usuallyfrom the deep peroneal nerve in the middle 1/3 of the leg. We think that the data we obtained in our research will reduce therate of important complications such as neurovascular injury in interventions planned for the deep peroneal nerve and thestructures adjacent to the nerve.
