A unique variation of the common peroneal nerve: a case report.

This variation was observed in the left lower extremity of a 75-year-old male cadaver fixed with formalin, ethanol and glycerol solution. The common peroneal nerve was divided into six terminal branches. These branches were identified as deep peroneal nerve, superficial peroneal nerve, two muscular branches to the tibialis anterior and two muscular branches to the peroneus longus. Knowledge of the variations of the common peroneal nerve and its branches is important in knee and proximal leg operations [ABSTRACT FROM AUTHOR]
