Could herniated nucleus pulposus the same with cervical radiculopathy?

Not the same: Radiculopathy is caused by nerve irritation/inflammation. This can be caused by bone spur (arthritis), herniated disk, and/or foraminal stenosis from disk collapse.

Yes?: Not sure what the question is, but a cervical herniated nucleus pulposus can certainly pinch or irritate a cervical nerve root and cause cervical radiculopathy with pain and/or numbness/tingling down the arm in particular patterns.
