腰椎牵引对下腰痛患者的疗效存在争议。本研究采用T2标测技术评价腰椎牵引后椎间盘含水量的变化，并探讨T2值变化与奥斯韦斯特里功能障碍指数（ODI）/视觉模拟评分（VAS）评分的相关性。行正中矢状位T2加权成像和T2标测，以确定Pfirrmann分级和T2值。结果牵引组Pfirrmann Ⅱ ~ Ⅳ级髓核（NP）T2值和Pfirrmann Ⅱ级纤维环（AF）T2值在牵引后的变化有统计学意义（P < 0.05）。每例患者5个椎间盘的平均NP T2值的变化与ODI/VAS评分呈强相关（r = 0.822，r = 0.793）。10次牵引导致Pfirrmann II-IV级退变椎间盘中NP的定量T2测量值显著增加，并在随后6个月内缓解了患者的临床症状。每例患者5个椎间盘的平均NP T2值的变化与ODI/VAS评分的变化密切相关。
ObjectiveThe effect of lumbar traction on low back pain (LBP) patients is controversial. Our study aims to assess changes in the intervertebral disc water content after lumbar traction using T2 mapping and explore the correlation between changes in the T2 value and Oswestry Disability Index (ODI)/visual analogue scale (VAS) score.DesignLumbar spine magnetic resonance imaging was performed, and the ODI/VAS scores were recorded in all 48 patients. Midsagittal T2-weighted imaging and T2 mapping were performed to determine the Pfirrmann grade and T2 value. Then, the T2 values were compared between pre- and posttraction, and the correlation between changes in the T2 value and ODI/VAS scores were examined.ResultsIn the traction group, the changes in the nucleus pulposus (NP) T2 values for Pfirrmann grades II-IV and the annulus fibrosus (AF) T2 values for Pfirrmann grade II were statistically significant after traction (P < 0.05). Changes in the mean NP T2 value of 5 discs in each patient and in the ODI/VAS score showed a strong correlation (r = 0.822, r = 0.793).ConclusionT2 mapping can be used to evaluate changes in the intervertebral disc water content. Ten sessions of traction resulted in a significant increase in quantitative T2 measurements of the NP in discs for Pfirrmann grade II-IV degeneration and remission of the patients' clinical symptoms in the following 6 months. Changes in the mean NP T2 value of 5 discs in each patient were strongly correlated with changes in the ODI/VAS score.
