China48 participantsStarted 2020-09-01

Plain-language summary

Observational study The purpose of this observational study was to understand the quantitative assessment of the degree of degeneration of lumbar facet joints, and to improve the Weishaupt grading system by using gray-scale curve fitting and imaging parameters. The main questions it aims to answer are: How to realize quantitative analysis of lumbar facet joint degeneration in patients with chronic low back pain with MRI? The MRI information of patients with different grades of articular process joint degeneration has been statistically summarized in nearly 5 years
