Removal of a section of spinal cord - affect on a future cure?

Here are a few more

One question, the aim of the surgery was to remove bone fragments? The picture 24...that doesn't seem very good idea, to press the cord like that, isn't it?

Thanks for showing the pictures btw.

Hi Ox,

You are welkom, No the aim of the surgery was (pure hope) to remain some funtions back, maybe from an Asia A to B, or C, but it was not the case. The surgery was not necesary because my compression was not that big. thas why they did not do it in the first pleace. later i wendt to Dr.Reis by my self. he did not remove any bone fragment from my cord, but a piece of the disc that was pressing the cord a little bit as I said, and he did he's procedure to remove everyting abnormal like Arachnoid cysts, Arachnoiditis and syringomyelia etc,

And yeah, you're right about the picture 24... it looks pretty scary to me to, I wonder what Dr., young has to say about that

Thas why maybe he disrupted the artery of Adamkievicz with the surgery. I dont know, just a guess

Saludos y un abrazo

Ahora no estaba seguro de si eras el mismo del otro foro o no

Gracias por la respuesta y un fuerte abrazo.

Dr. Young, we often see GSW-caused SCI where there was no cord penetration, while the bullet passed very close to the cord. We are told that the combination of tissue shock wave and bullet heat can damage the cord tissue without having to penetrate the cord tissue. Is that not the case?

KLD,

This is a very controversial area. Unfortunately, the only U.S. study on this subject by the Department of Defense (DOD) was stopped by the General Accounting Office because it involved the shooting of anesthetized dogs. The DOD has funded a number of studies on the subject of how improvised explosive devices can cause shock waves to damage the spinal cord and the data is confusing or not convincing.

Nobody, in my opinion, has provided convincing evidence that a bullet passing through the body can create shock wave that would penetrate vertebral column to affect the spinal cord. Most of the studies indicate that spinal cord injury in the presence of even very powerful blasts occur because the whole body is accelerated and hits something. Three decades of experience of contusion models of rat spinal cords have shown a minimum velocity of about 0.5 m/sec and the indentation is at least 10-20 mm at this velocity is necessary to cause severe spinal cord injury. Higher velocities may be effective with less indentation.

I don't know about bullet heat but I do know that heat does not penetrate from in tissues. For example, when we do electrocoagulation of tissues (for hemostasis), we know that application of heat to create temperatures sufficient to coagulate tissues will not cause damage to cells 5 mm away. So, the likelihood is very low that even a very hot bullet would cause sufficient heat to penetrate the vertebral column to the spinal cord.

Finally, one Chinese study of gunshot induced spinal cord injury was done by the Chinese military in pigs. That study showed that when the bullet did not touch the spinal column and did not cause a fracture of the spinal cord, they found no damage of the spinal cord.

This of course leaves unexplained cases of gunshot induced spinal cord injuries where there is no evidence of any bony damage. One possibility is that a bullet passing through tissue in front of the thoracic spinal cord may disrupt blood vessels that feed the spinal cord. The artery of Adamkivicz is an example of a crucial artery that bring blood from the aorta to the spinal cord. The bullet may cause a stroke of the spinal cord.

Dr. Young

Can you please give me some comments on the pictures, what do you think about the way that he press the spinal cord, is that normal ?

Please give me some comments !

Thanks in advance

Please replay Dr. Young

Maybe a stupid cuestion but what doe you think about mijn spinal cord is it in a bad shape. What can you tell me from what you see ? What is you Opinion obout it

Johnnie,

I don't think that the MRI shows that your spinal cord is in "bad shape". I generally don't think that MRI's provide accurate information about how severe the damage is. What MRI's are very important is showing compression of the spinal cord.

There is a new form of the MRI called diffusion tension imaging (DTI). We have been employing that in our trials in Hong Kong, because they show the white matter coming up to the injury site (and crossing over). We want to see regeneration.

No Wise, I didn't mean no MRI, I meant the pictures from my sugery on my post nr. 15 and 16
Please look at the pictures at nr. 15 and 16

Thanks in advance

Your spinal cord in the pictures do not look like it is in "bad shape" either. Are you thinking that your spinal cord was being treated roughly in the surgery? A lot of surgeons push the spinal cord around like this in surgery. I don't think that it does the spinal cord much harm as long as it is being done slowly and gently. Unfortunately, you can't see how fast it is being done with still pictures.

Thank you so much, Doc
