Growth arrest lines
Growth Arrest Lines
Growth arrest lines, also known as Harris lines or Park's lines, are horizontal lines visible on radiographs of the long bones of children. They represent periods of temporary cessation of bone growth due to severe systemic illness, malnutrition, or trauma.
Pronunciation
Growth arrest lines: /ɡroʊθ əˈrɛst laɪnz/
Etymology
The term "growth arrest lines" is derived from the English words "growth" (from the Old English grōwan, meaning "to grow"), "arrest" (from the Old French arester, meaning "to stop or stay"), and "lines" (from the Latin linea, meaning "string, thread"). The term "Harris lines" is named after the British radiologist, Henry Albert Harris, who first described them in 1926.
