Mr Orpen had a long sporting involvement while at school and University with national and international success. With a busy family and professional career, sport continues to play a large role in relaxation. He remains active and competitive in sport and has competed in marathons, long distance triathlon events, cycling competition and swimming events. He has a great passion for the visual arts.
Mr Orpen's clinical practice and research interests involve a broad range of spinal surgical topics but particularly disc replacement surgery, vertebral body augmentation (kyphoplasty/ vertebroplasty) and minimally invasive spinal surgical techniques.
Currently he is concentrating on teaching the technique of minimally invasive fusion surgery with inter body fusion both in the UK and Europe. Although teaching of consultant level surgeons may occur at the Ridgeway Hospital with patients being informed if this is occurring , all surgical cases will be undertaken by Mr Orpen himself.
Mr Orpen serves as a clinical spinal lead for the Bone and Joint Journal specialty channel and regularly reviews for this Journal: boneandjoint.org.uk
Mr Orpen is a fellowship trained spinal surgeon. His primary medical training was in South Africa. After this he emigrated to the UK to continue training on the Oxford post graduate surgical training program, initially in surgery and then in the field of Orthopaedics.
It was during this time that he developed a special interest in spinal surgery and so focused on further training as a spinal surgeon. This included specialist training in Oxford, Bristol and Reading after becoming a fellow of the Royal College of Surgeons of Edinburgh.
He remains actively involved in research and has published and presented extensively both in the UK and internationally on the topic of orthopaedics and spinal surgery. This includes contributions to textbooks and scientific papers. He remains actively involved in training junior doctors and preparing them for examinations.
Mr Orpen is a clinical lead in spinal surgery for the Bone and Joint Journal and contributes a regular article on important aspects of spinal surgery. He has also taken a particular interest in the training of other spinal consultants in the technique of minimally invasive spinal fusion throughout Europe.
