Sample item

A posterior dislocation of the hip most commonly endangers which nerve?

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

The answer and the reasoning

D. Sciatic nerve

The sciatic nerve lies posterior to the hip joint and can be injured in posterior dislocation. This may produce weakness below the knee and posterior thigh symptoms.

Option by option

  • A. Obturator nerve

    Obturator nerve is medial in the pelvis and thigh.

  • B. Femoral nerve

    Femoral nerve is anterior to the hip joint.

  • C. Superior gluteal nerve

    Superior gluteal nerve is at risk with injections in the wrong gluteal quadrant, not classically posterior dislocation.

  • D. Sciatic nerve (correct)

    Correct. The sciatic nerve is closely related to the posterior hip capsule.
