A 26-year-old woman sustains a laceration to the anterior ankle. Vital signs are stable (BP 118/76, HR 82, RR 16). Physical examination reveals weakness of foot dorsiflexion and numbness in the first web space between the great toe and second toe. Sensory examination of the lateral foot is intact. MRI shows scar tissue at the anterior tibial nerve. She denies pain or motor deficits in the lower leg. Which nerve was most likely injured?
- A)Common fibular nerve
- B)Superficial fibular nerve
- C)Deep fibular nerveGABARITO
- D)Sural nerve
- E)Tibial nerve
