Nerves can be injured either mechanically (transection or
compressionCompression of the median nerve
Cpr - adult
Cpr - child (1 to 8 years old)
Cpr - infant) or from a lack of blood supply/nutrients/toxins (like a neuropathy).
The prognosis for
recoveryRecovery position - series depends on the degree of damage and the
duration over which damage was occurring - hence the wide variation in recovery of nerves after injury. Injury to the sheath of the nerve (the myelin) means that the nerve will almost always recover. Injury to the nerve itself (the axon) means that there is a chance that the nerve will be permanently damaged. Nerve can regrow if they are still connected to the nerve cell body in the spinal cord, although regrowth occurs very slowly (like less than 1mm per day) - the nerve will only regrow if it is still connnected to its origin in the spinal cord. Also, after 12-18 months the parts of the nerve farthest from the origin that the regrowth has not reached will die and further recovery is unlikely to recur.
How can we tell what kind of damage and how much has occurred. The clinical examination can sometimes give a clue - deficits that do not recover over time suggest axon damage. EMG and nerve conduction studies can also give clues to this.
If the nerve is re-exposed to the injurious agent, further damage can occur (for instance a disc fragment or recurrent stenosis after surgery)
Good luck
I`m a Brazilian Physical Therapist, and i read your question...
Its very important for this kind of surgery (low back surgery) for Radiculophaty the reason for the pain.. Tha radicuphaty has many reasons,Compressive, Inflammatory, Infectious , Isquemic , Neoplasics and Traumatics...
So, its important first of all search the real problem for the Radiculophathy.
The pain lessens when the doctor releases the pressure into the nerve, but more important than that, is to find the reason that the pain is happening....
Try to find a Good doctor, or u can make lots of another surgerys without good results....
Sorry again for my bad english... hope i could help you..
