Answer

Symptoms are dependent on the site of the lesion.

  • The most common reported symptom is wrist drop.

  • If the lesion is high above the elbow, then numbness of the forearm and hand may be an additional symptom.

  • If the lesion is in the forearm, sensation typically is spared despite the wrist drop.

    • Pain in the forearm resembling tennis elbow may be prominent.

    • This presentation is initially acute for several days to weeks.

  • If the lesion is at the wrist, patients report isolated sensory changes and paresthesias over the back of the hand without motor weakness.
