Hi,
Thank you for posting your query.
I have noted your sister's symptoms and recommendations by her neurosurgeon.
Her symptoms are due to canal stenosis in the cervical region (neck). This would only cause pain and weakness in arm, and not the leg.
Leg and back symptoms occur with lumbar canal (lower back) stenosis.
So, the recommendation to do
laminectomy in the neck region seems appropriate.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
