If you lengthened your bones by 8 cm, are you taller by 8 cm or less?
The bones of the legs are not in a vertical axis.
I quoted my xrays results below. I got 8cm on left femur and 7.97 on the right one.
I cannot however come up with a very accurate number on my pre-CLL height. This is the measurements could have a different setup than those I currently have. did not necessarily have an exact setup. But the xrays showed 8cm.
I never cared much about how much extra cm I would get out of the CLL, but I did it as a challenge; like the way I did for a lot of other crazy stuff. All mattered to me was to do CLL perfectly; to get the best results, and try to beat other CLL'ers in the quality of results including minimizing the recovery time.
For future CLL'ers, I suggest doing a very accurate measurement in a clinic before the surgery and go back to that same clinic and repeat the measurements post-CLL and at exact same time of the day (as that of the pre-CLL).
