The common peroneal nerve is branch of the sciatic nerve, which supplies movement and sensation to the lower limb.
Injury to the common peroneal nerve
This nerve is in a very vulnerable position and may become damaged in knee injuries, during knee surgery or from plaster casts that are too tight. Injury at the level of the fibula may cause foot drop and/or numbness in the leg or foot.
