Your Answer
Correct Answer

Explanation

An injured peroneal nerve is most likely the cause of foot drop, a weakness in foot extension (ankle dorsiflexion). Its injury may be related to surgery, anesthesia, patient positioning, idiopathic, or multifactorial. Saphenous (branch of femoral nerve) and sural nerves are pure cutaneous sensory nerves and injury would thus not result in weakness.
