【摘要】：目的比較不同運動狀態(tài)下正常與退變腰椎節(jié)段三維有限元模型的應(yīng)力變化特點及量效關(guān)系,分析中醫(yī)推拿手法對退變腰椎節(jié)段力學(xué)調(diào)衡作用機(jī)制。方法建立完整、真實人體脊柱退變腰椎節(jié)段(L4~5)三維有限元模型,模擬腰椎節(jié)段前屈與后伸的生理活動。在加載外力即中醫(yī)推拿手法作用下,分析退變腰椎節(jié)段的應(yīng)力變化特點以及外加載荷逐漸遞增過程中退變腰椎節(jié)段的應(yīng)力變化,并與正常腰椎節(jié)段在不同運動狀態(tài)下的應(yīng)力、應(yīng)變改變趨勢進(jìn)行對比。結(jié)果在不同運動狀態(tài)下,人體腰椎節(jié)段椎間盤內(nèi)應(yīng)力分布、髓核、纖維環(huán)等結(jié)構(gòu)的彈性模量隨著腰椎退變程度的增加呈逐漸增大的趨勢。中醫(yī)推拿手法作用后能改變椎間盤內(nèi)的應(yīng)力分布,一定程度地增大椎管內(nèi)的空間,使神經(jīng)根所受的應(yīng)力減小,椎體、小關(guān)節(jié)應(yīng)力、椎弓根應(yīng)力后伸位大于前屈位;椎間盤內(nèi)部應(yīng)力前屈位大于后伸位;且均由上至下呈逐漸增大的趨勢。結(jié)論中醫(yī)推拿手法對人體退變腰椎節(jié)段力學(xué)環(huán)境的調(diào)衡起到改善和治療腰椎間盤病變的目的。同時,與人體正常腰椎節(jié)段三維有限元模型對比,從生物力學(xué)環(huán)境與特性改變角度研究腰椎退變的過程,能夠為中醫(yī)推拿手法在臨床中預(yù)防和治療脊柱退行性疾病的推廣應(yīng)用提供科學(xué)依據(jù),也為中醫(yī)推拿手法有效地預(yù)防和治療脊柱腰椎節(jié)段病損的生物力學(xué)機(jī)制的研究提供新研究思路。
[Abstract]:Objective to compare the stress change characteristics and dose-effect relationship between normal and degenerative lumbar segmental 3D finite element models under different motion conditions, and to analyze the mechanism of mechanical adjustment of traditional Chinese massage manipulation on degenerative lumbar segment. Real human spine degenerative lumbar segment L4 (5)) three-dimensional finite element model to simulate the lumbar segment flexion and extension of physiological activities. Under the loading of external force, that is, Chinese massage manipulation, The characteristics of stress change in degenerative lumbar segment and the stress change of degenerative lumbar segment in the process of increasing applied load are analyzed, and the stress of degenerative lumbar segment in different motion state with normal lumbar vertebrae is analyzed. Results the stress distribution in lumbar intervertebral disc, nucleus pulposus, nucleus pulposus, The elastic modulus of the fibrous ring structure increases gradually with the increase of the degree of lumbar degeneracy. The stress distribution in the intervertebral disc can be changed by the manipulation of traditional Chinese massage, and the space in the spinal canal can be enlarged to a certain extent. The stress of nerve root was decreased, the stress of vertebral body, facet joint, pedicle stress was greater than that of anterior flexion position, the stress of intervertebral disc in anterior flexion position was greater than that in posterior extension position. Conclusion the manipulation of traditional Chinese medicine can improve the mechanical environment of degenerative lumbar vertebrae and treat the disease of lumbar intervertebral disc. Compared with the three-dimensional finite element model of normal lumbar vertebrae, the process of lumbar degenerative change was studied from the point of view of biomechanical environment and characteristic change. It can provide scientific basis for the popularization and application of Chinese massage manipulation in the prevention and treatment of spinal degenerative diseases. It also provides a new idea for the study of biomechanical mechanism for the effective prevention and treatment of spinal and lumbar segmental lesions by Chinese massage manipulation.
