| 目的 探讨实时剪切波弹性成像评价腰椎间盘突出症患者腓肠肌弹性的价值。方法 选取临床确诊为单侧腰椎间盘突出症且接受侧隐窝入路选择性神经根阻滞联合臭氧消融术及脉冲射频治疗的患者100例，采用实时剪切波弹性成像技术检测治疗前后紧张状态下双侧小腿腓肠肌的平均（EMean）及最大（EMax）弹性模量值（kPa），并进行统计分析。结果 治疗前患侧紧张状态腓肠肌EMean为（11.28±2.60）kPa，EMax为（15.26±2.63）kPa，均较健侧减低（t=78.241、64.634，P均<0.001）。治疗后患侧紧张状态腓肠肌EMean为（13.18±2.38）kPa，EMax为（17.63±2.73）kPa，均较治疗前增高（t=6.407、14.815，P均<0.001）。不同肌力状态下，治疗前和治疗后紧张状态腓肠肌的EMean、EMax值差异均有统计学意义（P均<0.001）。治疗前及治疗后当肌力增加时，紧张状态腓肠肌EMean、EMax值亦增加，不同肌力间两两比较差异均有统计学意义（P均<0.05）。结论 通过实时剪切波弹性成像技术检测腰椎间盘突出患者治疗前后紧张状态下腓肠肌的EMean和EMax，可定量分析肌肉组织恢复情况。 |

| Objective To explore the value of real-time shear wave elastography in evaluating gastrocnemius muscle elasticity in patients with lumbar disc herniation. Methods One hundred patients with clinically diagnosed unilateral lumbar disc herniation were selected.Selective nerve root block combined with ozone ablation and pulsed radiofrequency therapy via the lateral crypt was performed. The real-time shear wave elastography was applied to detect the mean elastic modulus (Mean) and the maximum elastic modulus (Max) of bilateral tense gastrocnemius musles (kPa) before and after treatment.Statistical analysis was done. Results The EMean and EMax values of ipsilateral tension in gastrocnemius muscle before treatment were (11.28±2.60)kPa and (15.26±2.63)kPa, lower than those of contralateral (EMean:kPa, EMax:kPa; t=78.241, 64.634, both P<0.001). The EMean and EMax values of ipsilateral tension in gastrocnemius muscle after treatment were (13.18±2.38)kPa and (17.63±2.73)kPa, higher than those before treatment (t=6.407, 14.815, both P<0.001). In different strength condition, EMean and EMax of gastrocnemius muscle before and after treatment were statistically significant (all P<0.001). With the myodynamia increasing, EMean and EMax also increased before and after treatment. The differences between patients with any two different myodynamia were statistically different (all P<0.05). Conclusion The muscle tissue recovery can be evaluated quantitatively by detecting EMean and EMax of tense gastrocnemius in patients with lumbar disc herniation using real-time shear wave elastography before and after treatment. |
