Histological study of lumbar intervertebral disc herniation in adolescents

Abstract

Herniated intervertebral discs are rare in children and adolescents constituting approximately 1-5% of all patients undergoing surgery for lumbar and lumbosacral intervertebral disc herniation. Preceding traumata and congenital anomalities have been reported as important factors for the pathogenesis of intervertebral disc prolapses in young patients. The present histological study is based upon 15 patients with lumbar disc herniation within an age range from 14 to 19 years. Only in one case, was adequate trauma reported. All patients exhibited degenerative changes of the disc, similiar to those observed in adults. These changes were marked in 11 patients (73%). Thus, as known from adults, also in isolated traumatic disc herniation of adolescence, pre-existing degeneration of the disc has to be considered. If such changes are present, trauma has the significance of only transitory deterioration of the previous disc degeneration.
