Question 1

what is the nerve root injury that causes drop foot?

Accepted Answer

Deep peroneal: Isolated drop foot is due to deep peroneal (aka fibular) nerve injury on lateral side of the knee or below; if there is also difficulty turning the foot in, the common peroneal nerve may be involved (lateral side of the knee or a little above).+loss of leg/foot sensation also.It may also be due to L5 nerve root injury in the lower back from degenerative disc disease/disc bulging at the l4-5 level.

Question 2

ideas? what nerve root injury causes drop foot?

Accepted Answer

L5: L5 nerve root injury causes foor drop.  This may occur from trauma, severe stenosis or disc herniation.
Hoep this helps.

Question 3

any way to differentiate c8 vs.t1 nerve root injury? intrinsic weakness, diffuse hand atrophy/especially thenar, no thumb abd, ext, opposition. horners syndrome. i feel like a "cervical" injury may be causing thoracic pathology to be overlooked.

Accepted Answer

See below:  The muscle weakness you describe can come from an ulnar neuropathy, C8-T1 radiculopathy, or even compression of the lower portion of your brachial plexus.  Weakness with a Horners syndrome is concerning for a lesion compressing the nerves outside your spine or even lower cervical/upper thoracic spinal cord pathology.  See you MD ASAP for exam, imaging, and EMG studies.

Question 4

what tests are needed for spinal nerve root damage/injuries? damage in neck affecting both hands/arms,but left more than rt.is this a spinal cord inj?

Accepted Answer

MRI: You likely will need a MRI of the neck spine after an initial evaluation with your doctor. Sometimes,  a nerve conduction test may also be needed if the mri is not conclusive.

Question 5

mri says: "acute to subacute injury at l5-s1 with s1 contusion and disc herniation with effacement of the left lateral recess and nerve root".  what does effacement mean in this context?

Accepted Answer

Effacement : It means you are having indentation of the nerve root which could produce discomfort. You need to let the physician who ordered the test to decide what treatment would be appropriate. Good Luck

Question 6

i have a nerve injury to c5/c6 nerve root in my plexus.  my brachioradialis reflex barely any response.  what else do i need for diagnosis?

Accepted Answer

Evaluation: By interventional pain specialist. History taken and physical examination by a specialist is 85% of the cervical pain diagnosis. To support the diagnosis imaging (ct, mri) or nerve conductivity test are commonly used.

Question 7

confirmed first rib injury with brachial plexus involvement.  nerve root c5 and c6 injured at brachial plexus near first rib.  chances of healing?

Accepted Answer

Brachial plexus : Depends on the length of time since the injury and the extent of the injury.  If it involves the insulation of the nerves (myelin) recovery is 3 weeks to 3 months if no further injury.  If the wires themselves (axons) are injured it depends on how bad they are injured. Can take 6-12 months if not injured past point of ability to repair.

Question 8

severe fracturing and poss nerve root avulsion to t-spine 11 mnths ago. er missed injury after mva, and now i can't get any doctor to diagnose. advice?

Accepted Answer

See specialist : I would suggest that you see a spine specialist.  They can provide a thorough evaluation and provide advice.  Good luck.

Question 9

what does nerve root effacment mean?

Accepted Answer

Nerve being pressed : Effacement means that the nerve is being compressed hard enough that it actually changes the shape of the nerve- rather than a round structure, it is being flattened.  This is often secondary to a bulging intervertebral disc, but can be caused by other masses lying next to the vertebral column.

Question 10

what is effacement of the right exiting nerve root?

Accepted Answer

Being pressed on: This means the nerve root is being pressed on as it exits the spine. For example, it could be pressed on by a disc or by changes in the bones or ligaments related to arthritis. However, just because a scan may show the nerve being pressed on doesn't mean it is causing symptoms. This has to be decided after speaking with and examining the patient.
