Age can be defined in several ways: bone age,
age at development of secondary sexual characteristics,
age at menarche and dental age.
These parameters have all been described as means to define physiological age,
during pediatric age there are several factors that have an impact on the development and proper growth of a child,
chronological age is not necessarily indicative of the degree of biological maturation.

Findings and procedure details
The bones in the hand and wrist are the most suitable indicators of skeletal maturity during the different phases of postnatal development. In the majority of healthy children,
there is an established sequence of ossification for the carpal,
metacarpal and phalangeal bones,
which is remarkably constant and the same for both sexes (Table 1 and Table 2). The bone ossified from the primary center is the diaphysis,
while the bone ossified from the secondary center is the epiphysis.
Bone age plays an important role in the determination of biological age from infancy to before adulthood. There are factors,
environmental that determine it,
as well as pathologies that alter it. It is important to know that depending on the age group we can choose the type of study that will determine the bone age with greater specificity. The most updated method since 1950´s is that of Greulich and Pyle,
as well as the most recent electronic versions.
