Quantitating the effect of prosthesis design on femoral remodeling using high-resolution region-free densitometric analysis (DXA-RFA)

What is it about?

This paper describes a technique that compares bone remodelling that is consequence of using various femoral implant design. We can now do this in a quantitative and high-resolution manner based on an X-ray based imaging modality called dual X-ray absorptiometry (DXA) and a quantitative strategy called Region Free Analysis (RFA).

Why is it important?

Before this work, most quantitative analysis of DXA imaging is done base on regions that pool data distributed anatomically over the image and, hence reduce our ability to resolve small spatial changes over time. This allows us now to understand in more detail how different prosthesis perform and learn the pros and cons of alternative designs.
