a vaginal delivery was complicated by a severe depression of the right shoulder. MRI shows a single nerve root avulsion of the brachial plexus. which of the following could it be:
C5
C6
C7
C8
T1

Someone asked me this and I did not how to explain it very well.

Someone asked you this randomly or you got it from an actual exam?

I normally associate complicated vaginal deliveries with Erb's palsy which would be C5 and C6.

I'm not sure how one would go about determining if it was solely C5 or C6

I had this question --- possibly on UW? The answer is C5.

its C5...basically the head is going away from the shoulder. Similar scenario if a guy falls off of a motorcycle and is head and shoulder are going in opposite directions.
