Due to peroneal nerve injury. which caused foot drop. after 5 months of enjury. the situation now is still the same. is surgery the only option at this time? last emg mentions a partial lesion with no evidence of regeneration and active degeneration?

Very hard to answer your question without seeing the actual EMG results. It is not clear where the nerve was injured, whether it was axonal loss or demyelination, whether there is still a site where the nerve is continuing to be damaged and what percentage of the fibers are still viable. It is also not even clear what type of surgical intervention you are referring to without more information.

If there is scar tissue or a direct nerve laceration, surgery may not be useful at this time. Also depends upon whether clear compression demonstrated Likely, not of distinct value based on current data
