Evaluation of Bone Length Measurement

Evaluation of Bone Length Measurement Using Lunar iDXA

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:
