Ask any surgeon why he or she does anything and the explanation will always be based on a theory. What we can say is that surgeons are rarely lacking in reasons for what they do and why. Ideally placed at the coalface of activity, surgeons observe the results of their efforts and are, therefore, equally ideally placed to drive changes and innovations that result in better outcomes.
Indeed, the greatest successes in translational medicine come from surgeons. Transplantation medicine, burns surgery, parenteral nutrition and joint replacements are examples of the connection of intellectual and observational dots that link a surgical problem with a solution that has changed how we treat certain conditions.
