Hi
I would like to comment, mostly for the new people to the group. All of these articles are one sided. The author and some surgeons have an agenda against hip resurfacing. The retention rate of the BHR and other devices has been recorded and the records are available to people. The first place to look are the national registries
http://www.surfacehippy.info/nationalregistries.php Those are the statistics.
Then start listening to the video interviews by myself and Vicky with the top hip resurfacing surgeons. They address all of this negative press and give a complete story. Here are my interviews:
http://www.surfacehippy.info/shvideos/videosdoctor.phpAll of my recent interviews include the doctors response to the negative press about hip resurfacing and the negativity of MOM metal on metal THRs and Hip Resurfacing.
Mr. McMinn addresses the negative press here:
http://www.surfacehippy.info/mcminnnegativepr.phpThe information in the National Registries and the video interviews are not opinions, the information is based on facts. Many of the top resurfacing surgeons have done thousands of resurfacings and they post their retention rates. The overall retention rate was 99.9% worldwide before 2006 when the US surgeons jumped in and started doing hip resurfacing. Now the retention rate is 96% If you look at the retention rates for THRs for overall, males and females, it is really not any better.
We all have to realize there is no perfect hip device or solution. There will always be some problems with both THRs and hip resurfacing. The way we can best assure a good outcome is to choose the top surgeons that do thousands of these surgeries and have good records.
It is easy to write articles and say something isn't good based on opinion and half facts. The only way you know that you can't believe the information is to read other statistic based information. That will be from the national registries and from the hip resurfacing doctors own series of hip resurfacings.
The folks that have been here a long time realize the above information, but new people can easily be frightened by this type of negative press. Unfortunately, the ASR did not have a good record. Also many less experienced surgeons did not place acetabular cups properly causing a lot of revisions. The really experienced surgeons realized early on, often by instinct and knowing a person physical build, that the cups needed to be placed properly to make the bearing work well. Also there seem to be a lot of Metal on Metal THRs that have had problems. Even with THRs the components must be placed properly for the 2 pieces of the bearing to work properly. If the acetabular cup was misplaced, there could be edge loading in a THR, too. So many things have happened to make metal on metal hip resurfacing look bad. We need to look at actual statistics to see how well metal on metal hip resurfacing works. There are thousands of us, just on this discussion group that have well working hip resurfacings. Here is a survey done by the Yahoo Surfacehippy group of 850 folks that had hip resurfacing and their results:
