Hip pain may be 'hangover from evolution'

In an attempt to uncover the reason behind the common occurrence of shoulder, hip and knee pain in humans, scientists at the University of Oxford studied 300 specimens from different species spanning 400 millions years to see how bones changed subtly over millennia. Using CT scans of these 300 ancient specimens housed at the Natural History Museum in London and the Smithsonian Institution in Washington, scientists were able to create a library of 3D models to pick out variations to the shapes of single bones over millions of years. They found that as species evolved from moving around on 4 legs to standing up on 2 legs, the anatomical necks of the femur grew broader to support the extra weight. With the thickening of the neck, the risk of arthritis developing increases. Similarly in the shoulder, thickening of the bone led to narrower grooves and lesser space for tendons passing through to move, leading to pain in some people when they reach overhead.

Lianne Marie Victoria Laruan Thank you very much for your comment. Just a side track, we have a muscle in our forearm called palmaris longus, and 20% of the human population do not have it, that is because of evolution that this so called "usele...

This is quite an interesting finding, and probably can explain why hip and back pain are very common. Although we cannot prevent evolution from taking its course, at least there are some things we can do, like maintaining the right posture and being ...
