[Significance of radiologic skeletal age determination in clinical practice].

Skeletal development is an important maturity indicator during childhood. In clinical practice determination of skeletal age is helpful for the diagnosis of disorders of growth and development. Most hormones have specific effects on skeletal maturation. Thus, different disease states (growth disorders, disorders of pubertal development, chronic disorders of the bowels, kidneys, heart etc.) are characterized by retardation or acceleration of skeletal maturation. Therapeutic effects as well as side effects of hormones can be monitored by skeletal age determination. Typical disharmonic patterns in the appearance of bone centres of hand and wrist have been found in certain disorders of development.
