Nikolai Bogduk AM is a retired Australian anatomist, and emeritus professor of the University of Newcastle Bone & Joint Institute, Australia. His research and publications were primarily on the anatomical sources and causes of chronic spinal pain and headache, as well as the development of new diagnostic techniques and treatments for these conditions. He has made significant contributions to the field of spinal anatomy, biomechanics, as well as spinal pain diagnosis and management.

Bogduk's research focused particularly on the causes and management of spinal pain. He has authored numerous books, book chapters, and peer-reviewed articles in these areas, and his work is widely cited in the fields of pain medicine, orthopedics, and physical therapy. Some key contributions include:

He has also published over 100 chapters to books on spinal pain and headache.

Bogduk has published anatomical research, randomised controlled trials, observational studies, and reviews. The main themes of his published research were determining the innervation of the spinal column, examining the biomechanics of the spine, the development of diagnostic tests for neck and low back pain, and developing and looking at minimally invasive treatment techniques such as radiofrequency neurotomy.

The Spine Intervention society also present a grant called the "Nikolai Bogduk Young Investigator Grant."
