Sample item

Which movement is primarily lost after injury to the long thoracic nerve?

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

The answer and the reasoning

A. Scapular protraction

Long thoracic nerve injury paralyses serratus anterior, impairing scapular protraction and causing medial winging when the patient pushes against a wall.

Option by option

  • A. Scapular protraction (correct)

    Correct: serratus anterior protracts and stabilizes the scapula.

  • B. Elbow flexion

    Elbow flexion is mainly supplied by musculocutaneous nerve.

  • C. Thumb opposition

    Thumb opposition depends largely on the median nerve.

  • D. Wrist extension

    Wrist extension depends on radial nerve innervation.
