Growth recovery lines
Transverse metaphyseal lines visible on radiographs indicating periods of growth arrest followed by resumption of normal growth.
Full Definition
Growth recovery lines, also known as Harris lines or arrest lines, are transverse sclerotic bands seen in the metaphyses of growing bones on radiographs. These lines represent periods when longitudinal bone growth was temporarily interrupted due to illness, malnutrition, or metabolic disturbance, followed by resumption of normal growth. Multiple lines may be present, indicating repeated episodes of growth disturbance. These findings provide valuable information about a child's growth history and can be helpful in cases of suspected child abuse or chronic illness.
Usage
Usage note: Document the number and location of lines; consider correlation with clinical history.
