Evaluation of Bone Length Measurement
Evaluation of Bone Length Measurement
The purpose of this study is to determine if Lunar iXDA scanning with the use of a computer
 software program can make accurate measurements of the length of leg bones compared to
 conventional x-rays.
The investigators would like to see how well the calculation of bone length using Lunar iDxa
 compares to conventional x-ray since the Lunar iXDA exposed patients to less radiation than
 conventional x-rays.
Inclusion Criteria:
