What Causes Constant Numbness In The Leg After Spinal Fusion Surgery?
Recovery may continue for up to a year.
Detailed Answer:
I read your question carefully and I understand your concern.
The necessary time for fusion to consolidate and for nerve damage to heal may vary among different patients. In most of them results should be seen during the first 3-6 months but in some cases it can reach up to a year. Of course the longer it goes the less likely it is for regeneration to take place so percentage of improvement goes diminishing. At more than 6 months there is a real risk that there has been some permanent damage I won't lie about that. But as I said improvement in some patients may continue for up to a year. In terms of what you can try there isn't something else which you should try for now, only physical therapy and pain treatment as needed.
If symptoms persist for a year with no improvement I would schedule another imaging exam, both to confirm that fusion has taken place as it should as well as to confirm that there might not be other causes responsible at other levels which were not addressed by surgery.
I remain at your disposal for other questions.
