This study aims to investigate the relationship between cervical disc degeneration and bone quality of the adjacent vertebral body and sub\u2010endplate bone with a new MRI\u2010based bone quality score in patients over 50\u2009years with cervical spondylosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively reviewed 479 cervical disc segments from 131 patients. Disc degeneration at levels C3\/C4\u2013C6\/C7 was graded using T2\u2010weighted MRI. Vertebral body quality (VBQ) score and sub\u2010endplate bone quality (EBQ) score from C3 to C7 were computed from T1\u2010weighted MRI images. Additionally, bone mineral density (BMD) of the cervical vertebrae was measured in 52 patients using a novel phantom\u2010less quantitative computed tomography (PL\u2010QCT) system. The correlation between bone quality score and Pfirrmann grade was analyzed and risk factors for VBQ and EBQ were further evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Significant differences were found in cranial VBQ among different Pfirrmann grades, with a score of 2.55\u2009\u00b1\u20090.54 for Grade 5 discs, which was lower compared to Grades 4 (2.70\u2009\u00b1\u20090.56) (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05) and 3 (2.81\u2009\u00b1\u20090.58) (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01). Caudal VBQ for Grade 5 discs (2.43\u2009\u00b1\u20090.52) was also significantly lower than for Grade 3 discs (2.66\u2009\u00b1\u20090.54) (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01). EBQ scores decreased with increasing Pfirrmann grades. Negative correlations were observed between both cranial and caudal VBQ and EBQ scores and Pfirrmann grades. Grades 4 and 5 discs were identified as independent risk factors for decreased caudal VBQ and EBQ, whereas only Grade 5 was a significant risk factor for decreased cranial EBQ.
