Mr David Bell is a Consultant Neurosurgeon in neurospinal surgery, based at London Bridge Hospital. He has a specialist interest in complex spine surgery, where his clinical work covers all complex disorders of the spine including pain, trauma and disease, with the exception of scoliosis. He divides his clinical practice between Kings College Hospital and his private practice at London Bridge Hospital, part of HCA Healthcare UK.

Most disorders of the spine are self-limiting and do not need surgery. Wherever possible, Mr Bell tries nonsurgical treatment before invasive procedures. Where surgical intervention is needed, he is trained in minimally invasive techniques. Mr Bell attained his medical degree in 1996 in Edinburgh, where he completed his Basic Surgical Training before transferring to London for his specialist training in Complex Spinal Neurosurgery. He went on to become a Complex Spinal Neurosurgeon at Kings College Hospital, London in 2008, where he acted as the regional clinical lead for spinal cancer and trauma until 2020, establishing exceptional standards of treatment.

Between 2015 and 2021, Mr Bell was the Regional Network Lead for South East London and Kent, and he was an executive member of the British Association of Spinal Surgeons. He also served as the National Lead for the British Spinal Registry (BSR), a national quality improvement tool used to assure quality of surgical care across the United Kingdom.

Mr Bell regularly attends and lectures at conferences in the United Kingdom and abroad. He has an active medicolegal practice acting as an expert witness with an interest in Cauda Equina Syndrome. His research in both Cauda Equina Syndrome and Thoracic Disc herniations has been published in over 20 peer-reviewed scientific papers.
