    I had c5-c7 Anterior Cervical Discectomy with Fusion because of herniated discs and severe spinal compression, with cervical myelopathy. I was diagnosed after having an MRI.

    I had all the classic symptoms

    Bad Gait
    hyperreflexia
    clonus
    etc..

    In addition, I also had Thenar eminence atrophy which still remains today after the surgery.
    I have searched and asked if Thenar eminence atrophy is a common symptom of Cervical myelopathy and have never received a clear answer. I was happy to see your article.

    “This is a picture of atrophy of some hand muscles (the thenar eminence) that commonly accompanies cervical myelopathy.”

    Can you please elaborate on how common this is with cervical myelopathy?
    Is the atrophy permanent?
    what can be done to rebuild the thenar eminence muscle?

    Thank You for your time.

    Thenar atrophy is not too uncommon a sign of myelopathy. I would say about 10-20% of patients with myelopathy display thenar atrophy. The exact cause (what tracts are dysfunctional) is not very well defined. Once the cause (spinal cord compression) is eliminated, the return of thenar muscle bulk is not common. I cannot remember a patient with muscle mass return but I do confess that I have not looked for it so I may be mistaken. You can use grip strengthener devices to try and restore bulk.
