Which nerve injury could lead to a condition characterized by an inability to lift the foot?

The peroneal nerve, also known as the common fibular nerve, is responsible for the movement of the muscles that control foot dorsiflexion, which is the action of lifting the foot upwards towards the shin. An injury to this nerve can lead to a condition known as foot drop, where the individual has difficulty in lifting the front part of the foot, resulting in dragging or slapping of the foot during walking. This inability to dorsiflex the foot can severely affect mobility and stability.

The tibial nerve primarily innervates muscles that are responsible for plantarflexion (pointing the toe) and flexing the toes, and injury to this nerve would typically affect movements related to those actions, rather than the ability to lift the foot itself.

The radial nerve is responsible for the innervation of muscles that extend the forearm and wrist, thus having no direct involvement in foot movements and would not lead to issues with lifting the foot.

The ulnar nerve is mainly involved in the movement of the hands and fingers and does not relate to foot motion or dorsiflexion.

In summary, injury to the peroneal nerve specifically impacts the control of foot dorsiflexion, causing difficulty in lifting the foot, making it the
