Dr Ashish Diwan Specialist Orthopaedic Spine Surgeon

Dr Ashish Diwan Director of Spine Service
(MBBS, MS(Ortho), DipNB, MNAMS, FRACS, FAOrthA, PhD)
Dept. of Orthopaedic Surgery at St. George Hospital

Dr Ashish Diwan (MBBS, MS(Ortho), DipNB, MNAMS, FRACS, FAOrthA, PhD) is the Director of Spine Service at the Department of Orthopaedic Surgery, St. George Hospital, University of New South Wales. He is also the Director of Bone Biology at the Orthopaedic Research Institute. Within the University of New South Wales, he also functions as the Post Graduate Coordinator for the St George & Sutherland Clinical School. His University profile can be accessed here and his current H-index and citations can be accessed here.

Following his orthopaedic surgical training, he received training in advanced spinal surgery at the Hospital for Special Surgery (HSS) in New York City, which is the largest Orthopaedic Hospital in the US and is always ranked No 1 in the world for musculoskeletal problems. Dr Diwan was awarded the prestigious Philip D. Wilson Award at the Hospital for Special Surgery (HSS) New York. He is now an International Ambassador for HSS.

Dr Diwan has mentored and tutored numerous spinal surgeons over the years. He was part of the global Trainers Team for prodisc lumbar and cervical prostheses and he currently teaches rebalancing of the spine using minimally invasive posterior spinal fusions and minimally invasive lateral access surgery to the spine. He has also developed novel approaches to decompressing the spine where the stability of the spinal column is maintained. His current treatment development passions include bio-surgical approaches to regenerating the spinal disc and developing a nucleus replacement device for patients who are undergoing microdiscectomy, where the current approach is to discard the sequestered disc material.

He is a recipient of the National Orthopaedic Surgery Fellows Foundation Award for outstanding achievements in the field of Orthopaedic Surgery. He was awarded the Merrill Lynch Global Innovation Award 2000. He is the Treasurer for the International Society for the Study of Lumbar Spine, a Delegate for AO Spine Asia Pacific, Director Asia Pacific for Society for Lateral Access Surgery, the Section Editor for International Journal for Spinal Surgery, Deputy Editor for the Asian Spine Journal. In the past, he has served on the Research Committee of the International Society for the Advancement of Spinal Surgery, and has been the Vice President of OTC-South Pacific, Topic Co-Chair (Spine) for Orthopaedic Research Society, Honorary Associate Professor in the Faculty of Engineering and IT of the University of Sydney and Guest Editor of Orthopaedic Clinics of North America on two occasions.
