After the lengthening ends for a period of time, the height shrinks

Edit Post

I am wondering why my height has shortened by 3cm compared to last month's measurement. my height before the surgery was about 167,4. my femur was lengthened by 7cm and after the lengthening my height was measured at 173cm but today's measurement is only 170cm.

I used the LON method to lengthen the femur. I always measure my height at night, before the surgery my height was constant at around 167.4 cm, so when my femur was lengthened by 7 cm my theoretical height should be 174 cm, but the highest I measured was 173 cm, compared to about 171 cm currently.

I would like to know why using externals with pins to lengthen my femurs causes the height to shrink.

I took x-rays today and came to the conclusion that the livelifetaller did not actually lengthen me by 7 cm, that their procedure does not cut the bone completely vertically, but obliquely, and that when they measure the length of the lengthening, they measure it from the lower part of the bone, which at first I thought that was new bone.
