Dr. Hiroshi Hashizume was born in Shingu City, Wakayama Prefecture, Japan in 1964. He graduated from Wakayama Medical University in 1989. After the completion of the 2 years residency program, Dr. Hashizume attended postgraduate school (PhD course) at Wakayama Medical University and studied hard tissue biology/histology under the direction of Prof. Tetsuya Tamaki. In 1995, Dr. Hashizume became a board-certified orthopaedic surgeon (Japanese Orthopaedic association) and started clinical practice and research of the spine field. Succeeding his first mentor in the spine research, Prof. Mamoru Kawakami, Dr. Hashizume came to be interested in the mechanisms of radicular pain generated by the herniated disc. He went on to study the central pain mechanisms using an animal model under the direction of Dr. James Weinstein and Dr. Joyce DeLeo at Dartmouth College, New Hampshire, USA from 1997 to 1999. He practiced both clinic and research activity since he came back to Japan. Dr. Hashizume became a board-certified instructor of the spine surgery (The Japanese Society for Spine Surgery and Related Research) in 2003 and started the practice of microendoscopic spine surgery under the direction of Prof. Munehito Yoshida in 2008. At the same period, Dr. Hashizume attended the foundation of Wakayama Spine Study and started the collaboration with Prof. Noriko Yoshimura and Prof. Toru Akune at 22 Century Medical Center, The University of Tokyo. The Wakayama Spine Study is a population based cohort study to elucidate the prevalence, natural history, and impact on the individual/society of the degenerative spinal disorders.
Dr. Hashizume's research interest has been extended to wide range – intervertebral disc biology/pathology, pathomechanisms of spinal pain, and epidemiology of spinal disorders. Currently he is a member of The International Society for the Study of the Lumbar Spine, North American Spine Society, American Academy of Orthopaedic Surgeons, Orthopaedic Research Society, Asia Pacific Orthopaedic Association, Japanese Orthopaedic Association, and The Japanese Society for Spine Surgery and Related Research. He also contributes to the “Spine” journal as a reviewer since 2006.
