Hi, These are clear signs and symptoms of brachial plexus injury, brachial plexus is the plexus of nerves and their roots that emanates from shoulder and goes into the arm. He needs an MRI of brachial plexus 5-7 days after the day of injury as in the initial period there is so much swelling that it is not possible to see brachial plexus clearly. She needs to consult a neurosurgeon or a plastic surgeon who can repair the plexus. Take care. Hope I have answered your question. Let me know if I can assist you further.
