Objective:To provide ideas and references for improving the lumbar stability of flying personnel by reviewing the research progress and tendency on Schmorl′s nodes of lumbar spine in flying personnel. Literature resource and selection Relevant papers and monographs about Schmorl′s nodes published at home and abroad. Literature quotation Thirty-six published references were cited. Literature synthesis It is generally considered that Schmorl′s nodes of lumbar spine are cartilaginous nodes formed by the herniation of the intervertebral discs tissue into the vertebral body through the broken cartilaginous endplates. There are different opinions on the epidemiology and pathogenesis of Schmorl′s nodes of lumbar spine. Because most of them have no obvious clinical symptoms, they were once considered to be of no research value. However, the investigation showed that the further study on Schmorl′s nodes of lumbar spine in flying personnel is realistic. Schmorl′s nodes of lumbar spine may not only cause lumbago, but also are closely related to lumbar intervertebral discs degeneration. The formation of Schmorl′s nodes of lumbar spine in flying personnel will affect the viscoelasticity of lumbar intervertebral discs, and this will affect their anti-G and anti-vibration abilities, accelerate the degeneration of lumbar spine and intervertebral discs, and induce clinical symptoms or reduce flight endurance. Conclusions:Schmorl′s nodes of lumbar spine are closely related to lumbar disc degeneration and lumbar instability. Schmorl′s nodes are commonly seen in the lumbar spine and have an important effect on the overall stability of lumbar spine of flying personnel.
