As a registered spinal neurosurgeon in Australia, Dr Peter Geoffrey Lucas, attained a general neurosurgical fellowship inclusive of spinal surgery and then focussed principally on spinal surgery thereafter. In conclusion, while neurosurgeons and spinal surgeons both work with the nervous system, neurosurgeons have a broader scope that covers the entire nervous system, while spinal surgeons focus mainly or exclusively on the surgical treatment of conditions affecting the spinal column.
