Bone gets denser when regularly loaded. If left unloaded, the bone atrophies, becoming less dense. Because a total hip is fixed about a third of the way down from the top of the remaining leg bone, the upper part of the leg bone loses density over time. A BIRMINGHAM HIP^◊ loads the upper leg bone more like the way that it is loaded normally.

This is demonstrated in studies showing bone density improving from the pre-operated state⁽¹⁾. These studies show a decrease in the bone density of THRs, which has been demonstrated in many other studies.

Bone Mineral Density Ratio

Box plots of the BMD ratio in Gruen zone1(a) and Gruen zone 7(b). The median value is represented by the central, horizontal line. The 75% and 25% values are reprsented by the upper and lower borders of the box and the 90% and 10% value by the extensions of the vertical lines.
