June 30, 2015 – From a very philosophical standpoint hip arthroplasty is very unfair towards women!!!
Most men will have a socket size of 52 or over and therefore a 36 mms head can be used in all types of hip replacements. The 36 mms head is technically a “large head” and is a good option having serious resistance against dislocation. In addition men in general or not as lax / flexible as women and the risk of dislocation is significantly smaller. However the typical acetabular size in most women is 46 to 50. The small acetabular size in most … Read the rest
Yes, it is true.
Smith and Nephew was asked to respond to the long-known worse outcomes in females. This was precipitated by the UK’s National Institute of Clinical Excellence (NICE) raising their 10 year outcomes requirement from 90% where it been for years, to 95%.
Raising the bar left females and small sizes below the bar (along with a great many total hips as well, so expect more fall-out), and males well above the bar. If you remember, the UK registry, on which their regulators base decisions, had an average doctor’s resurfacing volume of just 4 per year, … Read the rest

I have not been offering metal on metal resurfacing in the withdrawn smaller sizes. We have been offering just polyethylene in these sizes. I am attaching my abstract for an upcoming meeting. Yes, we use the implants shown on the Synovo Preserve site. We offer this to both men and women. We always use a cementless acetabular component and usually a cementless femoral component as well. Let me know the best way to reach patients. We are happy to talk with patients. I am concerned that … Read the rest
I am still using the BHR. I will resurface appropriate women (i.e. with head size over 48mm…).
I think the majority of young men men have osteoarthritis (OA) secondary to FAI (which I treat by arthroscopy) but about half of the young women have some form of acetabular dysplasia/DDH, and the other half have OA because of FAI. Thus tall phycially active women with OA from FAI can expect to do well with resurfacing, but women with dysplasia are probably better off with THR.
I have now performed over 300 resurfacings. I offer free email consultations.
