Birmingham Hip "Dual Mobility Insert"

[jsblock11]

Anyone heard of this? Looks like Smith and Nephew filed Section 510k with the FDA so this should be something coming soon?

I'm debating the pros/cons of retaining the BHR cup, and using a dual mobility femoral component as per a couple of surgeon's suggestion, and came across this while reading up on the topic.

Interesting that there may soon be a device specifically made for "partial" revisions where the BHR cup is retained? I assume it will be very similar to a standard dual mobility femoral component, which is usually a ceramic head, which articulates inside a larger poly head, which then articulates in the BHR metal cup.
