skeletal maturity

Skeletal maturity refers to the stage of development of a person's bones, particularly the growth centers known as epiphyses. This process begins in the embryo and continues through childhood and adolescence until full skeletal maturity is reached, typically when the growth plates fuse.1

Bone age, determined through X-rays of the hands and wrists, is a key indicator of skeletal maturity. It reflects the extent to which these growth centers have matured and can be compared to the bone age of healthy children of the same chronological age. This measurement is crucial for assessing growth and development, as deviations from chronological age can indicate endocrine disorders. For instance, delayed bone age is seen in growth hormone deficiency, while accelerated bone age can occur with growth hormone-producing tumors.2

During puberty, significant changes occur in skeletal growth, muscle development, and body composition, leading to increased height and strength, with distinct differences emerging between sexes. Skeletal maturity is closely linked to the onset of adolescence and the development of secondary sexual characteristics.345
