sjmom: Age has a lot to do with the choice. For younger people, resurfacing is great, because you are removing less bone. To do a resurfacing, the femur is machined & a hollow hemisphere is attached. This acts as the ball that fits into the socket of your hip joint. Orthopaedic surgery is an awful lot like carpentry, actually. The bone underneath can eventually become necrotic, which requires a total replacement down the line. But as less bone was removed for the resurfacing, there is then more to work with once a THR is necessary.
Resurfacing has been around since the 1960's. It fell out of favor when THRs were seen to be getting better results. But new surgical methods are now showing resurfacing to be very promising.
Good luck! Either way, it will be wonderful to get back mobility & get rid of the pain.
