Official title:
Analyses of Bone Age Determined by Ultrasound in a Cohort of Brazilian Control Children and Adolescents: Comparison With Conventional Bone Age Determined by X-Ray
Aiming to validate the use of bone age determined by ultrasound (BAUS) in Brazilian
children, normal control students will be studied. X-Ray bone age (RXBA) and BAUS will be
determined in 500 children and adolescents of both genders, with chronological age varying
from 6-16 years.
Concordance analysis and the correlation between both BA determination methods will be
performed.
Bone age is a valuable method to recognize the maturation status of development and growth.
Classical analyses is performed by using the Greulich and Pyle X-Ray measurement. Such
analyses have some restrictions such as intra- and inter observer variability, and variable
synchronicity of bone maturation.
Bone age determined by ultrasound (BAUS) has been indicated as a fast and reproducible
method, allowing decimal BA determination and avoiding the need for X-Ray.
Our aim is to validate the BAUS method in Brazilian normal controls. School students of both
genders, with age varying from 6 to 16 years will be included.
