The Fellowship also included training in fluoroscopic guided injection therapies. As the Senior Fellow, I was responsible for the day-to-day running of the Spinal Unit, working with the managerial staff to maximise efficient use of medical staff and theatre time. The Spinal Unit has an excellent research record and I had the opportunity to undertake and complete two long-running trials along with several other projects during my Fellowship, presented at both domestic and international meetings.
