Abstract:

BACKGROUND: Lumbar disc herniation is the most common cause of lumbago in clinic, which seriously affect the patient’s daily life, study and work. Therefore, studies on biomechanics of lumbar intervertebral disk benefit to prevent and treat the diseases associated with lumbar intervertebral disk.
OBJECTIVE: To summarize the biomechanical progress of lumbar intervertebral disk.
METHODS: The first author retrieved China National Knowledge Infrastructure and PubMed database for literatures published from 2009 to 2014. The key words were “intervertebral disc, nucleus pulposus, biomechanics, fibrosis annulus, cartilage” in Chinese and English, respectively. Articles regarding biomechanical characteristics of lumbar intervertebral disk, nucleus pulposus, fibrosis annulus and cartilage were included, and repetitive
 studies were excluded. Totally 5 072 articles were retrieved initially. In accordance with inclusion and exclusion criteria, 41 articles were included in result analysis.
RESULTS AND CONCLUSION: We can fully understand the pathogenesis, development and adverse consequences of diseases related to the lumbar intervertebral disk by summarizing the structural features and internal pressure of lumbar intervertebral disk and the effect of different loads, biomechanical characteristics of lumbar intervertebral disk with degenerative changes and establishment of mechanical model of lumbar intervertebral disk. It is of directive significance for daily health care of the lumbar intervertebral disk and how to better use “force”, a physical factor, to solve the lumbar intervertebral disk problems.
