From the lecture halls of Hokkaido University to the international stage of spine surgery, Professor Dr. Kuniyoshi Abumi has etched an extraordinary legacy over a career that spans more than four decades. Celebrated for his innovative work in spinal reconstruction and cervical spine surgery, Professor Abumi has become a towering figure in global orthopaedics, earning the highest respect from peers and students alike. His appointment as the Orator for APSS–APPOS–MSS 2025 is a tribute to this legacy.

Professor Abumi commenced his academic journey at Hokkaido University School of Medicine, where he obtained his Doctor of Medicine degree in 1976. He then completed his orthopaedic surgery residency at Hokkaido University Hospital from 1976 to 1980, followed by a spinal fellowship until 1982. Driven by an early curiosity in spinal biomechanics, he pursued postdoctoral research from 1984 to 1986 at Yale University’s Bioengineering Laboratory, USA, working under the guidance of the esteemed Prof. Manohar M. Panjabi.

Returning to Japan, Professor Abumi built a remarkable academic career at Hokkaido University. He held positions as Assistant Professor (1992), Associate Professor (1997), and ultimately Professor of Spinal Reconstruction at the Hokkaido University Graduate School of Medicine in 2010. In 2012, his lifelong dedication was honored with the title of Professor Emeritus. Since 2016, he has served as Chief Director of the Center for Spinal Disorders at Sapporo Orthopaedic Hospital, continuing to influence spinal care and surgery.

Professor Abumi’s commitment to advancing spine surgery is perhaps most visible through his leadership in professional societies. He has been an integral part of the Asia Pacific Spine Society (APSS), serving as Japan's National Delegate in 2010 and President of APSS from 2015 to 2017. His guidance was pivotal in expanding the society’s regional and global footprint. He has also held key roles in the Cervical Spine Research Society – Asia Pacific Section and maintains long-standing memberships in the Scoliosis Research Society, the Cervical Spine Research Society, and the Japanese Society for Spine Surgery and Related Research.

His stature extends beyond Japan. Professor Abumi served as Visiting Professor at the Third Hospital, Beijing University Medical Center (2005–2016), and at Xi’an Jiaotong University (2015–2018). He was named Honorary Member of the Nepal Orthopaedic Association and serves as International Patron of the Association of Spine Surgeons of Nepal. With over 200 peer-reviewed publications and numerous editorial board roles, including with Spine and European Spine Journal, Professor Abumi’s voice continues to shape academic orthopaedics worldwide.

Professor Dr. Kuniyoshi Abumi’s career is a blueprint of excellence, integrity, and visionary leadership. His contributions to spine surgery, both regionally and globally, have elevated standards of care and knowledge. As a mentor, innovator, and thought leader, his impact will be felt for generations. We are honored to celebrate his achievements and welcome him as the Orator at the APSS–APPOS–MSS 2025.
