A woman I know has been losing height at a rate of 10cm a year following a severe spinal injury. How is this possible? What kind of injury could cause such progressive loss of height? Could this be a genetic defect? Are there any disorders that cause this type of shrinking?

In case it could be relevant, her brothers are very tall.

i asked this question as well on fitness.stackexchange.com and on skeptics.stackexchange.com, they think here is a better place, so they downvoted my question, i hope you don't downvote me too, I just want to know what's wrong with this woman before she dies, that's all. I searched all around the web for disorders, couldn't find any! i just want an explanation –  Fischer May 26 '13 at 21:42

I dont have a definite answer for this but this is what I speculate: spinal injury can cause paralysis which leads to atrophy (wasting away) of skeletal muscles. This may be the cause of the observed reduction in height. –  WYSIWYG May 27 '13 at 5:36
    
atrophy happens because of prolonged disuse –  WYSIWYG May 27 '13 at 7:00
    
Her height is that of a small bottle of cola? You expect us to believe you know a human being who is ~20cm tall? –  terdon May 27 '13 at 14:11
