Grade Ⅳ degeneration was correlated with interverteral disc protrution and HIZ and HIZ has good correlation with both disc bulge and disc protrution. 3 讨论 儿童及青少年下腰痛的发病率随年龄增长逐步上升。目前国内外文献对椎间盘退行性改变的关注对象多为老年人,而对年轻患者关注较少。Zitting等 [ 5...
Grade 1-3 of Pfirrmann grading was classified into low grade group, while grade 4-5 was classified into high grade group. Water (calcium) concentration, water (HAP) concentration, calcium (water) concentration, HAP (water) concentration and Eff-Z of intervertebral disc were mea...

The Pfirrmann score of the intervertebral disc in the HO group had a significant positive correlation with the McAfee grade ( R=0.54, P=0.01) and a significant negative correlation with the ROM ( R=-0.75, P=0.01). At 2 years after the operation, when the Pfirrmann score of the ...
different grade of Pfirrmann grading system Objective: To compare the biological characteristics of nucleus pulposus cells in intervertebral discs with different grade of Pfirrmann grading system. Method :Human nucleus pulposus cells were isolated by collagenase digestion method and cultured.they were...
Pfirrmann grade ≥ III was defined as disc degeneration [24]. Two raters (XC and YW) independently assessed the disc degeneration. The third rater (SL) settled the discrepancy between the two raters. 2.5. Training Two researchers (XYL as rater 1 and YW as rater 2) performed the DH and ...
For the cells in Grade Ⅳ, their processes were even longer, large amount lysosomes were accumulated and large vacuoles were formed. Under the same cellular density and culture conditions, the growth rate of passage 2 cells were markedly faster in the cells of Grade Ⅰ and Ⅱ than in Grade ...
