Following a posterior dislocation of the hip, a patient develops weakness of dorsiflexion and eversion of the foot, along with sensory loss over the dorsum of the foot. Which nerve is injured?

• A Tibial nerve
• B Femoral nerve
• C Sural nerve
• D Common peroneal (fibular) nerve ✓

Explanation

The common peroneal nerve is the most commonly injured nerve in the lower limb due to its superficial course around the neck of the fibula. Posterior hip dislocation or fracture of the neck of the fibula can stretch or compress this nerve. It supplies the muscles of the anterior and lateral compartments of the leg (dorsiflexors and everters) and provides sensory innervation to the dorsum of the foot.
