Sample item

Which nerve is vulnerable at the neck of the fibula and can produce foot drop?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Common fibular nerve

The common fibular nerve winds superficially around the fibular neck before dividing into deep and superficial branches, so trauma or tight casts can weaken dorsiflexion and cause foot drop.

Option by option

  • A. Tibial nerve

    The tibial nerve supplies posterior-leg and plantar-foot muscles.

  • B. Femoral nerve

    The femoral nerve supplies anterior-thigh muscles and sensation.

  • C. Common fibular nerve (correct)

    Correct: the common fibular nerve is exposed at the fibular neck.

  • D. Obturator nerve

    The obturator nerve mainly supplies medial-thigh adductors.
