Frax score from DEXA vs. Online Frax Calculator - difference?

Posted by loplady @loplady, Mar 2 9:19am

Has anyone calculated their Frax using the online calculator using Fraxplus and gotten very different results? I entered all my information in exactly as what is on my Dexa and got a score of 7.3% for Major Osteoporotic Fracture when my Dexa shows 15.5%. Both are adjusted for TBS. For hip, I got 0.6% vs. 2.6% from my Dexa. I also used the Canadian one to compare and it is very close to the Fraxplus online calculator. Just did this today so no, have not asked my endocrinologist.

Interested in more discussions like this? Go to the Osteoporosis & Bone Health Support Group.

I had different results but that was because for the DEXA my broken bones from years ago were included but I did not include them on-line. I decided that a broken finger from touch football (failed to jump high enough to catch the ball) and a broken ankle from slipping on a sheet of ice should not count as fragility fractures.

loplady, the dxa/TBS/FRAX only uses gleaned from the x-ray. The frax calculator score includes information from your personal history, which could be more or less accurate than the dxa calculated score.

I was thinking that but they did ask me the same questions before my DEXA scan so I thought they were included in the results. Big difference in the results which can influence a decision for meds vs. the natural approach, which I have been taking.
