Prof. Wood informed me of a scientific meeting in the evening and said that I had not been invited to dinner for almost a month, so I chose to meet with other doctors over dinner at the Boston Club, which has a long history of academic exchange between American and European doctors, and he wanted me to present my work to the audience. The evening session focused on some of the current new and popular techniques in spine surgery, including minimally invasive lumbar internal fixation and cervical artificial disc replacement, both of which I happen to have done a great deal of work on, and I presented some of my work that should impress the doctors in attendance. The reason for the long-standing reputation of the Provincial General Hospital’s spine surgery is also related to its solid, rigorous, scientific research work. Minimally invasive internal fixation of the spine and artificial disc technology of the spine have been used for many years in many hospitals, while the Massachusetts General Hospital has just started in minimally invasive internal fixation and is just getting ready to start in artificial disc replacement. I was impressed by the fact that theoretical reserves had been in place prior to this. While there is no doubt that minimally invasive internal fixation of the spine and artificial disc replacement of the spine have their technological leadership, the selection of the correct indication for surgery will always be a matter of ongoing discussion now and for quite some time to come.
