Cervical Nerve Root Sleeve Amputation

I am trying to find out what all of this means. Is physical therapy good or bad for this type of injury?  Is it possible for a neuro-surgeon to repair this?  Or, not?  Is there anything that we can do to try to help this nerve cure itself?  I have been searching the internet for weeks trying to find accurate information about this.  Neuro-surgery is not a topic that you can be a little off on.  I have reasearched the brachial plexus and have read all about the cords, divisions, trunks, roots, and branches.  My head is swimming trying to remember all of this information.   So, I was wondering If anyone here can help me with this.  My husband was working on the car with his hair tied back and had turned his head to the right so that he could better hear the noise that it was making.  Within a split second the alternator belt grabbed a piece of his hair, his head whipped around and the left back side of his head smashed against the engine ripping a large clump of his hair from his head throwing him backwards where he fell against the concrete floor which left about a four inch cut on the right side of his head above his ear  Blood was everywhere. The speed at which his head slammed against the engine caused  a half dollar size smash in his head with several long cracks radiating from the center.  His friend kept him lying down and told him not to move until the ambulance arrived (as that is what they always tell you to do). When the ambulance arrived he was surprised when they did not put him on a back board to stabilize his head and neck area, nor did they put his neck in a brace.  They just asked him if he could get up himself and get on the gurney, so he did. He was in and out of conciousness for the ambulance ride and most of the two hours that he was in the emergency room.  I arrived at the hospital about an hour after the injury had happened.  When I looked at his head I could not see the damage because there was a gigantic hematoma covering the injured area.  When I say gigantic I mean a hematoma that was about 5 inches in diameter and 3/4 to l inch or more thick. I was greatly alarmed by what I saw.  The male nurse came in to clean up the area so the doctor could stitch it closed.  I was shocked when he asked my husband to get up and walk over to the shower room so they could get rid of the hematoma.  So my husband got up and went with him.  They returned about 10 minutes later and my husband told me that the nurse put him in the shower and kept shoving down really hard on his head to squeese all of the blood out of the hematoma. I looked at his head amd I could see his white skull showing through the crack.  He told me that it was nothing to worry about.  When the doctor came in he stitched up my husbands head (which I left the room for) and then sent him home with a prescription for pain killers and said that he could go to work the next day. Needless to say, that did not happen.  I took him to the family doctor a couple of days later because he could not feel his left arm and hand except for his thumb and first finger, and the skin om his left leg and trunk were numb, so it was apparent that something else was seriously wrong. Also when he tries to look upward and move his head backwards or to the left he gets dizzy and loses his balance.  Our doctor had CT scans done of his head and neck and did not like what she saw so she referred him to a specialist.  The specialist then sent him to have an MRI done on his head and neck.  He then sent him to get a Mylegram.  When the results came back the doctor told him that there had been a lot of trauma to the area and said that my husband might, or might not, get any feeling back. He told us that all we could do is wait to see what it does in the next few months. My husband has been out of work for over three months now and the doctor just wants to see him once a month (for who knows how long) to wait and see what happens.  How long can we wait?  The waiting is killing us and we are afraid that he may damage himself further just waiting around as the numbness is now spreading to his right side. Any assistance with this would be greatly appreciated. The Mylegram report says: "There are mild to moderate anterior extradural compression defects at both C5-6 and C6-7. The extradural compression is particularly prominent at the C6-7 level. There is amputation of the right-sided nerve root sleeve at C6-7. There is suboptimum opacification of the nerve root sleeves at C5-6 plus on the left at C6-7. The suboptimum opacification of these three nerve root sleeves could be due to extradural compression. The nerve root sleeves at the other levels appear to fill adequately with Omnipaque. There are no findings on this study that are suspicious for intradural abnormalities." I guess I am asking if just waiting around is okay, or should we be getting a second opinion before more permanent damage may be done?  I am assuming that amputated means that some part of the nerve has been cut off.  If this is so, then why can't a neuro-surgeon go in and reattach it?  I thought that is what a neuro-surgeon does.  I don't mean to sound stupid but all of this is way above my head.  I love my husband and I will continue to love my husband no matter what happens.  We have not had any sex since before the accident happened as he no longer can.  I can deal with that.  He will be 49 years old in June so I know that he will never get it all back, and we can deal with that.  I just keep getting a sick feeling that all is not okay.  I know it is impossible for you to give a diagnosis about something that you know nothing about except for what I am telling you, but I was wondering if there was something else, or other options that we are not aware of, that we could do about this instead of just waiting, and waiting some more, with no idea of how long we should wait.  Therefore, any knowledge that you could give us about this situation, or where we could get any further information about it would be greatly appreciated.  Thanks.
