Objective:To provide references for the application of finite element model in the study of cervical vertebra by statistically analysing the frequency, numerical value, properties, and boundary setting of the finite element model and the corresponding material features as well as boundary settings in the literature.Methods:The literature on cervical vertebra-related finite element models was collected from CNKI, Wanfang, VIP, PubMed, Web of Science, and Embase databases from January 2013 to December 2023. The quality assessment was followed by manual screening. The data sources, application classification, material properties (Young’s modulus and Poisson’s ratio), and boundary conditions of cervical vertebra, cervical intervertebral, and cervical ligaments were statistically analyzed.Results:A total of 102 papers were included. The finite element models of the cervical vertebra were derived from medical image reconstruction modeling techniques, predominantly CT plain scan and magnetic resonance imaging. Among the 102 cervical vertebra models, the C3-C7 (lower cervical segment) model appeared with the highest frequency (19). The Young’s modulus of the cortical bone, cancellous bone, and posterior structure of cervical vertebrae were set at about 12 000 or 10 000, 440, and 3 600 MPa, respectively, and the Poisson’s ratios were mainly set at about 0.29 or 0.30, 0.29, and 0.29. The Young’s modulus of the cervical intervertebral disc endplate, nucleus pulposus, and annulus fibrosus were concentrated around 500 or 2 000, 1, and 100 MPa, respectively, and the Poisson’s ratios were set at about 0.40, 0.50, and 0.40, respectively. The Young’s modulus of the anterior longitudinal ligament, posterior longitudinal ligament, transverse ligament, ligamentum flavum, interspinous ligament, capsular ligament, and articular cartilage of the cervical spine were set around 30, 20, 20, 6-10, 4-8, 10 or 20, 10 MPa, and the Poisson’s ratios were set at aoubt 0.30, 0.30, 0.30, 0.30, 0.30, 0.40, and 0.30, respectively. The Young’s modulus of the upper cervical interdental ligament, lamina, cruciate ligament, nuchal ligament, and pterygoid ligament were set at about 10, 10, 10 or 20, 20, and 5 MPa, respectively, and the Poisson’s ratios were set at about 0.30. Head weight settings were more common at 50, 74, and 100 N.Conclusions:The finite element model of the cervical vertebra has great value in the study of cervical spondylosis, but further optimization is still needed in the assignment of material properties, mesh division, and model verification to improve the accuracy and clinical applicability of the model.

Objective To analyze the changes in morphology of intervertebral foramina in patients with cervical spondylotic radiculopathy (CSR) treated with fixedpoint lateral flexion and rotation manipulation based on three-dimensional (3D) reconstruction technology, so as to provide references for the effectiveness of manipulation treatment. MethodsForty patients with CSR were treated with fixed point lateral flexion and rotation manipulation once every other day for a total of 7 times and 2 weeks as a course of treatment. CT data of the patients before and after treatment were analyzed by using multifunctional CT, Mimics 21.0, Geomagic and SolidWorks 2017. The area of the intervertebral foramen, anterior and posterior diameter of the intervertebral foramen, upper and lower diameter of the intervertebral foramen were measured before and after treatment, as well as the infrared thermal imaging temperature differences of the bilateral neck and shoulder, front and back of the upper limb, and the VAS scores of the patients were observed before treatment, 7 d after treatment, 14 d after treatment and 1 month follow-up. Results Foraminal area, anterior and posterior diameters, upper and lower diameters of 40 patients were improved after treatment, and the temperature differences of infrared thermal imaging of patients before and after treatment were statistically significant. The VAS score of the patients decreased progressively. Conclusions Fixed point lateral flexion manipulation can significantly improve the shape of the intervertebral foramen in patients with CSR, so as to achieve the treatment purpose of relieving nerve compression.

Objective:To observe the effects of "pushing patella and extending knee" manipulation on the protein and mRNA expression levels of integrin β1 (ITGβ1) and phosphorylated adhesion plaque kinase (p-FAK) in rabbit knee osteoarthritis (KOA) model, and to investigate the mechanism of manipulations in the treatment of KOA.Methods:Twenty healthy 6-month-old New Zealand rabbits were divided into the normal group, the model group, the acupuncture group, and the manipulation group according to the random number table method. Among them, the model group, the acupuncture group, and the manipulation group were modeled using the modified Hulth method for KOA. After 7 d of successful modeling, the normal group and the model group did not receive any intervention, while the acupuncture group and the manipulation group received one acupuncture intervention and one "pushing patella and extending knee" manipulation intervention daily, respectively. After 2 weeks of treatment, the rabbit KOA model was executed by air embolization, and the protein and mRNA expression levels of ITGβ1 and p-FAK in knee cartilage were measured by Western blot and real-time polymerase chain reaction (PCR), respectively.Results:Compared with the normal group, the ITGβ1 protein expression level was decreased ( P<0.05) and p-FAK protein expression level was increased ( P<0.05), and the mRNA expression levels of ITGβ1 and p-FAK did not change significantly (all P>0.05) in the model group. Compared with the model group, the ITGβ1 protein expression level was increased ( P<0.05), the p-FAK protein expression level decreased ( P<0.05), and the mRNA expression levels of both ITGβ1 and p-FAK increased (all P<0.05) in the acupuncture group. Compared with the acupuncture group, ITGβ1 protein expression level increased ( P<0.05), p-FAK protein expression level decreased ( P<0.05), and mRNA expression levels of both ITGβ1 and p-FAK increased (all P<0.01) in the manipulation group. Conclusions:The "pushing patella and extending knee" manipulation can optimize the protein and mRNA expression levels of ITGβ1 and p-FAK in the articular cartilage of the rabbit KOA model.

Objective To explore the psychological status of patients after hand tenolysis and the pertinent nursing countermeasures. Methods 47 patients after hand tenolyais were selected and investigated their psychological status and relevant influencing factors with serf-designed questionnaire and symptom checklist-90(SCL-90). Besides, corresponding psychological nursing were applied. The SCL-90 results of Chinese Norm were adopted to undergo comparison with them and t test was chosen. Results On the first day after operation, the score of the investigation objectives was significantly different compared with that of the Chinese norm. After pertinent mental nursing, their symptoms alleviated, and no significant difference was seen between them. Conclusions There are obvious psychological obstacles in patients after hand tenolysis. The pertinent mental nursing has important effect on rehabilitation training and functional rehabilitation after hand tenolysis.
