摘要：背景:应用计算机技术和有限元法对传统中医推拿手法进行研究,给传统的中医推拿手法研究注入了活力。目的:分析手法治疗腰椎间盘突出症的机制,探求符合生物力学的治疗手法,明确手法治疗腰椎疾患的安全范围。方法:选择成年无腰椎疾患的男性志愿者,年龄28岁,身高170cm,体质量60kg。采用CT对L3～S1进行扫描,利用ADINA5.0构件软件,并赋予不同组织不同的材料属性,建立腰椎有限元模型,设定腰椎水平位、后伸10°位、前屈30°位状态,加载拔伸按压载荷,观察腰椎间盘、髓核和纤维环的受力改变情况。结果与结论:在拔伸按压状态下,腰椎前屈30°椎间盘组织的位移应变和应力变化最明显,提示在设定的条件下手法治疗腰椎疾患是安全的。
BACKGROUND： Computer and finite element methods have been used to explore manipulation treatment. OBJECTIVE： To explore the mechanism of manipulation treatment of lumbar intervertebral disc protrusion, investigate a way consistent with the treatment of biomechanics and confirm the safety scope of the manipulation of lumbar disorders. METHODS： One adult male volunteer with no spinal disorders, aged 28 years, 170 cm height and 60 kg body mass was subjected to CT scanning of the L3-S1 using Adina component-based software, and assigned different materials attributes to different tissues to establish lumbar spine finite element model. The level of lumbar spine position, extension 10 °, flexion 30 ° were set and subjected to pulling, extension and compression loads to observe force change of lumbar intervertebral disc, nucleus pulposus and annulus fibrosus. RESULTS AND CONCLUSION： Under pulling, extension and compression states, the intervertebral disc displayed the most obvious displacement, strain and stress changes at lumbar flexion 30 °, suggesting treatment of lumbar spinal disorders is safe in certain conditions.
