? about scolimeter

[Scolimomof1]

After reviewing my daughter's medical records, I noticed back in march of 2008 he reported a mid thoracic scoliometer reading of 18 degrees, also stating that "clearly her rotational scoliometer reading is significantly worse as well as the radiographic Cobb angle. She still has ope triradiate cartilages when measured from T6-L1 today was 51 degrees. Note this was march of 2009 report. So my question is would someone please explain all of this to me?? Thank you
