Intervertebral disc calcification syndromes in children

One hundred and twenty-seven cases of intervertebral disc calcification in children, including 11 previously unreported cases, have been analysed. A distinction is made between symptomatic and asymptomatic patients, whose age, sex and spinal distributions of the calcifications have been shown to differ. Radiologically detectable protrusions and later resorption of the calcifications are common events in symptomatic children, but are unrecorded in asymptomatic children. The spinal distribution of paediatric calcifications is quite different to that of adult and canine calcifications of the nucleus pulposus.
