How to Read a MRI of Cervical Nerve Compression Neck Pain Colorado Spine Surgeon

now we're going to look at a cervicalspine MRI of a patient with arm pain the patient doesn't have much neck pain and he has no spinal cord dysfunction in this MRI again you can see thespinal cord in the center surrounded by the white cerebral spinalfluid or water and the vetrebral bodies and the discs you can see a small disc bulge here andsmaller disc bulges here and here

since there's no real compression of thespinal cord the patient has no spinal cord dysfunction symptoms but if we do come to the right side wecan see these spurs that are compressing out of the canal at these two levels andthose are the spurs that are catching the nerve root on the right we can look at it from the top down view and we come up to the first level atC two three again spinal cord is clear the white

csf water around it these are the nerveexit polls here in here the C two three level looks normal we march down to the C three four level and again spinal cord has room the nerveholes have room this one is a a little tight but it still has plenty of room come down to C four five again the nerve holes are free the spinal cordis free come down to C five six

and here we see a nice big spur on theright side the left nerve root is exitingquite nicely the right nerve root here is compressedby the spur and this is one of the spurs causing this patient right arm pain we can pass by this level and go to thenext level at six seven and again see the same thing the left nerve hole is free there's a big spur on the right nerve hole and this nerve is compressedand this is what's causing him the arm pain from the C seven nerve

this is a side by side example of a normal level of the cervical spine and a levelwhere there's nerve compression again we noted before this nice largespur is compressing the exiting nerve route right here where the nerve root onthe opposite side is open here we can see again the vertebralbody the spinal cord where both nerve roots are free and clear andthere's no compression and either foramen so in this particular case thisspur is what's causing this patient's

neck pain and arm pain.
