If the common peroneal nerve is damaged, which action still has complete function?

The common peroneal nerve primarily innervates the muscles responsible for dorsiflexion, eversion, and toe extension. When this nerve is damaged, the ability to carry out dorsiflexion and eversion is often impaired. However, the action of inversion is primarily facilitated by the tibialis anterior and tibialis posterior muscles, which are innervated by the tibial nerve. Since the tibial nerve is not affected by the damage to the common peroneal nerve, the action of inversion remains intact. This distinction highlights the importance of understanding how nerve injury impacts specific muscle groups and their associated movements.
