easy · MCQ · Q-D755F2
A 28-year-old rock climber falls and sustains a fracture of the neck of the fibula. Upon physical examination, the patient cannot dorsiflex the foot, cannot evert the foot, and exhibits a 'steppage' gait. Sensation is lost over the anterolateral leg and the dorsum of the foot. Which nerve has been injured?
- A.Tibial nerve
- B.Common fibular (peroneal) nerveCorrect answer
- C.Obturator nerve
- D.Saphenous nerve
Solution
The common fibular nerve winds closely around the neck of the fibula, making it highly vulnerable to fracture at this site. Injury leads to foot drop (loss of dorsiflexion), loss of eversion, and sensory deficits on the anterolateral leg and dorsum of the foot.
