 My name is Hajime Utsunomiya, but everybody calls me Jimmy. This was called by Dr. Philippon at the very first day of my year. I am an international research fellow here from 2016 May. So I am an MD and PhD. I'm working with Dr. Philippon to learn his philosophy of the hypotroscopy. And I have been joining with more than 600 surgeries of Dr. Philippon in these two years. And I have been working on the research studies and biomechanical studies of the hip. As the great talk of Julia yesterday, she had a dysplastic hip, which is a shallow socket of the hip. And this is not very common in U.S. I would say the number of the patients with dysplastic hip in U.S. is 2 to 4%. And in Japan, with the hip pain, the dysplastic hip is called as 50 up to 80%. So this is totally a big difference. And the most important thing is that patients with shallow sockets are not very good candidates of hypotroscopy. Everybody in the world believes. But my supervisor, Soshi Uchida in Japan and Dr. Philippon, they are very aggressive to do hypotroscopy for this kind of dysplastic patients. So I came here to learn how to treat the dysplastic patients from Dr. Philippon. A traditional way to treat them is cut the bone of pelvis and rotate the bone and make a good coverage, which is a very traditional way, but which will take a very long time to recover for the athletes. So for the top level athletes to do this kind of surgery is kind of end of career. So to do hypotroscopy will help to clean up the joint. But just doing hypotroscopy might not resolve their initial problem, which is the smaller coverage of the acetabulum, which is a pelvic bone. I need to say the technology in Japan regarding hypotroscopy is not very high as here in U.S. So if the patient is going to somewhere in Japanese clinic, then the doctor will say you need to get the bone cut surgery. So that is one purpose for me to come here and learn a lot from the way of treating in U.S. So regarding the prevention, so this is very important word from Julia yesterday, but the dysplastic hip without pain is a kind of talented hip. So the talented hip then the athlete will get the very high performance. So how to make the high performance without pain or disability is very important for us. So that is one more important thing regarding the prevention of the injury of the hip with dysplastic patients.
