Bone Age Determined by Ultrasound (BAUS) in Brazilian Control Children
- Conditions
- Control, Population
- Registration Number
- NCT03190109
- Lead Sponsor
- Faculdade de Ciências Médicas da Santa Casa de São Paulo
- Brief Summary
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.
- Detailed Description
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.
