Hi Steve Welcome to Hip Talk
You are very young and are lucky to have Mr. Tracey as your doctor. He is very experienced in hip resurfacing. Most of our surgeons here in the US are not as experienced. A few are, but on the whole many have just done BHR training since May 2006.
You certainly are too young to have a THR if you can have a hip resurfacing. It sounds like you have tried it all and are probably ready for your hip resurfacing. The surgeons are good about determing when the time is right.
I had to travel from Ohio in the US to Beligum to get my new BHR from Dr. De Smet. I did not have health insurance and also wanted to use a very experienced surgeon. Dr. De Smet has done over 2400 hip resurfacings. You can't beat the overseas doctors for experience.
I have a lot of great personal stories from athletes with hip resurfacings
http://www.surfacehippy.info/athletes.php and many more plain personal stories
http://www.surfacehippy.info/hipstories.php Not too many from the UK.
If I can answer any questions for you, please don't hesitate to ask them. I had my hip resurfacing in March of 2006 and I was quite a bit older than you - I was 61 years old. I still wanted to stay active and not worry about a dislocaiton, so I choose to have a hip resurfacing. It is always the best option when you are a candidate.
Good Luck and keep in touch. Maybe you can write a little story for my website when you get your hip resurfaced.
