Relationship Between Adolescents Lumbar Disc Herniation And Lumbar Scheuermann's Disease And Scheuermann Like To Change

Objective To explore the relationship between lumbar disc herniation and Scheuermann’s disease in adolescents.Methods Lumbar MRI of237adolescents (less than25years old) suffering from low back pain were retrospectively reviewed. A total of1185lumbar segments from L1to S1were divided into three groups:lumbar Scheuermann’s disease group, Scheuermann’s sign group and no Scheuermann’s sign group. The incidence and degree of lumbar disc herniation was compared between the three groups and also between groups with different Scheuermann’s sign.Results (1) The male to female ratio was3.83:1,1.67:1and1.43:1for lumbar Scheuermann’s disease, Scheuermann’s sign and lumbar disc herniation.(2) The most frequently involved segment for lumar Scheuermann’s disease was L1/2and L4/5, that for Scheuermann’s sign and lumbar disc herniation was L4/5and L5/S1.(3) The incidence of lumbar disc herniation for Scheuermann’s disease group and Scheuermann’s sign group was44.90%(22/49)、40.54%(45/111), respectively. Both of them are higher than that of no Scheuermann’s sign group (12.78%,131/1025, p<0.05).(4) The incidence of lumbar disc herniation for those segments with Schmorl’s nodes, irregular endplate, lumbar anterior and posterior marginal intra-osseous cartilaginous node, vertebral body elongation was21.36%(22/103).34.19%(53/155),44.44%(4/9)、96.88%(31/32)、42.86%(6/14), respectively. The herniation incidence of all the groups listed above were higher than that of no Scheuermann’s sign group (12.78%,131/1025, p<0.05).While the incidence of lumbar disc herniation for those segments with vertebral wedging was not higher than that of segments without any Scheuermann’s sign(P=1.000).(5) The degree of disc herniation was more severe in segments with Scheuermann’s disease or Scheuermann’s sign than those without Scheuermann’s disease or sign.Conclusion (1) The incidence of Scheuermann’s disease, Scheuermann’s sign and lumbar disc herniation was higher for male than female.(2) The most frequently involved segment for lumar Scheuermann’s disease was L1/2and L4/5, that for Scheuermann’s sign and lumbar disc herniation was L4/5and L5/S1.(3) The incidence of lumbar disc herniation for Scheuermann’s disease group and Scheuermann’s sign group was higher than that of no Scheuermann’s sign group.(4) Of all the Scheuermann’s sign, posterior marginal intra-osseous cartilaginous node is most closely related to lumbar disc herniation.(5) Lumbar Scheuermann’s disease and Scheuermann’s sign may be an etiology for lumbar disc herniation in adolescents.
