bone age assessment

Radiological evaluation of skeletal maturation using standardized atlases to determine if bone development matches chronological age.

Full Definition

A standardized method of evaluating skeletal maturation typically performed using a single radiograph of the left hand and wrist. The degree of ossification and fusion of various bones and growth plates is compared to established atlases such as Greulich-Pyle or Tanner-Whitehouse methods. Bone age assessment is crucial in pediatric endocrinology for evaluating growth disorders, precocious or delayed puberty, and determining remaining growth potential. Significant discrepancies between bone age and chronological age may indicate underlying endocrine disorders, nutritional deficiencies, or genetic syndromes requiring further investigation.

Usage

Usage note: Always specify the atlas method used; express results in years and months when possible.
