ABSTRACT

Abstract Objective To evaluate the impact of the severity of lumbar degenerative disease (LDD) on sagittal spinopelvic alignment. Methods In total, 130 patients (mean age: 57 years; 75% female) with LDD-associated low-back pain were prospectively included. The severity of the LDD was defined by the following findings on anteroposterior and lateral lumbar spine radiographs: osteophytosis; loss of of height of the intervertebral disc; terminal vertebral plate sclerosis; number of affected segments; deformities; and objective instability. The disease was classified as follows: grade 0-absence of signs of LDD in the lumbar spine; grade I - signs of LDD in up to two segments; grade II - three or more segments involved; grade III - association with scoliosis, spondylolisthesis, or laterolisthesis. Spinopelvic radiographic parameters, including pelvic incidence (PI), lumbar lordosis (LL), discrepancy between the PI and LL (PI-LL), pelvic tilt (PT), and sagittal vertical axis (SVA), were analyzed according to the LDD grades. Results The radiographic parameters differed according to the LDD grades; grade-III patients presented higher SVA (p= 0.001) and PT (p= 0.0005) values, denoting greater anterior inclination of the trunk and pelvic retroversion when compared to grade-0 andgrade-I subjects. In addition, grade-III patients had higher PI-LL values, which indicates loss of PI-related lordosis, than grade-I subjects (p= 0.04). Conclusion Patients with more severe LDD tend to present greater spinopelvic sagittal misalignment compared to patients with a milder disease.


Resumo Objetivo Avaliar o impacto da graduação da doença degenerativa lombar (DDL) sobre o alinhamento sagital espinopélvico. Métodos Ao todo, 130 pacientes (dade média: 57 anos; 75% do sexo feminino) com dor lombar associada a DDL foram prospectivamente incluídos. A gravidade da DDL foi definida pelos seguintes achados nas radiografias anteroposterior e de perfil da coluna lombar: osteofitose; perda de altura do disco intervertebral; esclerose na placa vertebral terminal; número de segmentos afetados; deformidades; e instabilidade objetiva. Os pacientes foram graduados segundo a DDL da seguinte maneira: grau 0-ausência de sinais de DDL na coluna lombar; grau I - sinais de DDL em até dois segmentos; grau II - envolvimento em três ou mais segmentos; grau III - quando associada a escoliose, espondilolistese ou laterolistese. Parâmetros radiográficos espinopélvicos, como incidência pélvica (IP), lordose lombar (LL), discrepância entre a IP e a LL (IP-LL), versão pélvica (VP), e eixo vertical sagital (EVS) foram analisados de acordo com os graus de DDL. Resultados Houve diferença nos parâmetros radiográficos comparando-se os graus de DDL, com os pacientes de grau III apresentando maiores valores de EVS (p= 0,001) e VP (p= 0,0005), o que denota maior inclinação anterior do tronco e maior retroversão pélvica do que os pacientes de graus 0 e I. Pacientes de grau III também apresentaram maiores valores de IP-LL, o que denota perda da lordose relativa ao valor da IP, do que pacientes grau I (p= 0,04). Conclusão Pacientes com DDL mais grave demonstraram uma tendência a maior desalinhamento sagital espinopélvico comparados com pacientes com graus mais leves.

ABSTRACT

ABSTRACT Objective: With the increasing number and youth of patients with cervical spondylosis, people pay more and more attention to the cervical spine. Early diagnosis, intervention and treatment play an important role in the recovery of cervical spondylosis. With the continuous development of computer technology, the improvement of various modeling theories, and the application of image processing methods in orthopedics, new ideas are opened to observe cervical vertebra motion health. Methods: In this paper, the measurement of cervical motion is achieved by machine vision. A method of parameter measurement based on the constraint relationship of lower cervical motion is proposed. Based on image preprocessing, the left edge of the cervical vertebra was extracted and analyzed. Results: With the horizontal coordinate of registration point as the reference line, the changing trend of the angle between the left edge curve and the reference line of C4 and C5 vertebrae in the process of spontaneous flexion and extension of the cervical vertebrae was observed, and the movement rate of the cervical vertebrae was analyzed. Conclusions: It was found that the speed of the cervical vertebrae in the process of movement of the patients with cervical spondylosis showed jumping changes. Level of evidence II; Therapeutic studies - investigation of treatment results.

ABSTRACT

ABSTRACT Objective: To evaluate the impact of the severity of degenerative lumbar disease (DLD) on the occurrence of spinal deformity, as well as on the choice of treatment, whether conservative or surgical. Methods: This is a retrospective analysis of a prospective database. One hundred and thirty patients with low back pain and/or pain radiating to the lower limbs were included in the study and were graded on a DLD scale that considers total spine (panoramic) X-ray findings. The rates of adult spinal deformity (ASD) for the different degrees of the DLD scale were compared using the Chi-square test. The choice of treatment type, conservative or surgical, was also compared among the degrees of the DLD scale using Fisher's exact test. Results: The ASD rate was zero in grade 0 patients, 24% in grade I, 35% in grade II and 44% in grade III (P = 0.02). Grade III patients were more likely to be diagnosed with ASD (OR = 2.22; P <0.05; 95% CI = 0.90-5.45) compared to the other DLD grades. Only 7.7% of the patients were chosen for surgical treatment and there was no difference by the DLD scale grade. Conclusion: There was correlation between the DLD grading scale and the occurrence of ASD, with at least twice the chance of this diagnosis in DLD scale grade III as compared to the other grades. The treatment of choice was conservative in a very small number of patients analyzed, with no difference between the different grades of the DLD grading scale. Level of Evidence III; Retrospective analysis of prospective database (cohort).

Métodos: Trata-se de uma análise retrospectiva de um banco de dados prospectivo. Cento e trinta pacientes com dor lombar e/ou dor irradiada para o membro inferior foram incluídos no estudo e graduados por uma escala de DDL que considera achados radiográficos da coluna total (panorâmica). A taxa de ocorrência de deformidade da coluna vertebral no adulto (DCVA) foi comparada entre os graus da escala da DDL pelo teste de Qui-quadrado. A escolha do tipo de tratamento, conservador ou cirúrgico, foi comparada entre os graus de DDL pelo teste exato de Fisher. Resultados: A taxa de ocorrência de DCVA foi zero nos pacientes com grau 0, 24% nos pacientes com grau I, 35% nos pacientes com grau II e 44% nos pacientes com grau III (P = 0,02). Os pacientes com grau III tiveram maior probabilidade de ser diagnosticados com DCVA (OR = 2,22; P < 0,05; IC de 95% = 0,90-5,45) comparados com os dos indivíduos com outros graus. Apenas 7,7% dos pacientes foram escolhidos para tratamento cirúrgico, sem diferença quanto ao grau da escala de DDL. Conclusões: Houve correlação entre a escala de graduação da DDL e a ocorrência de DCVA, sendo ao menos duas vezes maior a chance dessa ocorrência no grau III comparado com os demais graus. Na imensa minoria dos pacientes, o tratamento escolhido foi o conservador, sem diferença entre os distintos graus de DDL.

ABSTRACT

OBJECTIVE@#To observe the changes of functional connectivity of brain pain-emotion regulation region in patients with cervical spondylosis of cervical type by functional magnetic resonance imaging (fMRI).@*METHODS@#Thirty-two subjects were selected. Of them, 16 patients with cervical spondylosis of cervical type were divided into an observation group and 16 healthy subjects into a control group. The patients in the observation group were treated with acupuncture at Tianzhu (BL 10), Jingbailao (EX-HN 15), Jianzhongshu (SI 15) and @*RESULTS@#In the observation group, the VAS score was (1.94±1.12) after the treatment, which was lower than (5.62±1.20) before treatment (@*CONCLUSION@#Pain involves the formation and expression of "pain-emotion-cognition". Acupuncture can systematically regulate the brain functional connections between cognitive regions such as dorsal prefrontal lobe and anterior cingulate gyrus and emotional regions such as insula and VTA in patients with cervical spondylosis of cervical type, suggesting that acupuncture has a multi-dimensional and comprehensive regulation effect on pain.

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy of zero-profile anchored spacer (ROI-C) in treating cervical spondylosis with osteoporosis.@*METHODS@#From May 2013 to May 2018, a total of 145 patients with cervical spondylosis were treated by ROI-C through anterior cervical spine approach. Among them, 31 patients were aged ≥60 years and had osteoporosis by bone density measurement, and they were retrospectively analyzed. Including 9 males and 22 females, aged 60-84 years old with an average of (69.12±7.65) years. There were 23 cases of single-segment fusion, 6 cases of two-stage fusion, and 2 cases of three-stage fusion;and 41 devices of ROI-C fusion was placed in the patients. Operation time and intraoperative blood loss were recorded;Japanese Orthopaedic Association (JOA) scores and visual analogue scale(VAS) were respectively used to evaluate the neurological function and neck pain before and after operation. The cervical curvature (expressed as Cobb angle), the height of the intervertebral space at the surgical segment, and the intervertebral fusion were observed at postoperative and follow-up periods were observed by image data.@*RESULTS@#All patients were followed up for 12-24(15.6±4.4) months after operation. The operation time were from 75 to 113 (101.33±10.25) min and intraoperative blood loss were from 14 to 51 (33.18 ± 16.56) ml. Among these 23 patients with fusion of single segment, the operation time were 75 to 98 (85.47±8.70) min and intraoperative blood loss were 14 to 30(21.18±6.56) ml. JOA scores of all included patients were increased from 9.66±2.12 preoperatively to 14.36±1.24 at the final follow-up (@*CONCLUSION@#Anterior cervical approach with ROI-C for the treatment of elderly patients with cervical spondylosis and osteoporosis had reliable clinical effect, short operation time, less intraoperative blood loss, and can effectively restore cervical curvature and intervertebral space height, and has advantages of fewer complications and higher successful rate of fusion.

ABSTRACT

ABSTRACT Herbert von Luschka, a German anatomist, was the first to describe the developmental changes in the anatomical structures of the cervical spine. Degenerative cervical myelopathy (DCM) represents a collection of pathological entities that cause compression of the cervical spinal cord, resulting in a clinical syndrome typified by spasticity, hyperreflexia, pathologic reflexes, finger/hand clumsiness, gait disturbance and sphincter dysfunction. In the cervical spine, certain patients are more likely to have myelopathy due to a congenitally narrowed cervical spine canal. Degenerative changes are more common at C5 and C6 or C6 and C7 due to the increased motion at these levels. Additional contributors to canal narrowing are infolding of the ligamentum flavum, olisthesis, osteophytes, and facet hypertrophy. Myelopathy will develop in approximately 100% of patients with canal stenosis greater than 60% (less than 6 mm sagittal disc cord space). Classically it has an insidious onset, progressing in a stepwise manner with functional decline. Without treatment, patients may progress toward significant paralysis and loss of function. Treatment requires surgery with either anterior or posterior decompression of the area of narrowing, and probable fusion. Factors of a poor prognosis include symptoms lasting for more than 18 months, increased range of motion in the cervical spine, and female gender. In this study, we give an overview of the state-of-the-art in DCM, with a focus on the pathophysiology, clinical presentation, differential diagnosis, imaging evaluation, natural history, treatment options and complications. Level of evidence III; Review article.


RESUMO Herbert von Luschka, anatomista alemão, foi o primeiro a descrever as mudanças no desenvolvimento das estruturas anatômicas da coluna cervical. A mielopatia cervical degenerativa (MCD) representa um conjunto de entidades patológicas que causam compressão da medula espinhal cervical, resultando em uma síndrome clínica caracterizada por espasticidade, hiperreflexia, reflexos patológicos, perda de destreza manual, distúrbios de marcha e disfunção de esfíncteres. Certos pacientes têm maior probabilidade de desenvolver mielopatia na coluna cervical em decorrência de estenose congênita do canal cervical. As alterações degenerativas são mais comuns em C5 e C6 ou C6 e C7 devido ao aumento da mobilidade nesses níveis. Outros fatores que contribuem para a estenose do canal medular são hipertrofia do ligamento amarelo, listese, osteofitose e hipertrofia de facetas. A mielopatia cervical ocorre em aproximadamente 100% dos pacientes com estenose do canal superior a 60%, isto é, espaço da medula discal sagital menor que 6 mm. Em geral, tem início insidioso, progredindo gradualmente com declínio funcional. Sem tratamento, os pacientes podem progredir para paralisia significativa e perda de função. O tratamento requer cirurgia de descompressão anterior ou posterior da área estenosada e provável fusão. Os fatores de mau prognóstico prevalecem no sexo feminino e incluem sintomatologia com duração superior a 18 meses e aumento da amplitude de movimento da coluna cervical. Neste estudo, apresentamos uma visão geral do estado da arte em MCD, com ênfase de fisiopatologia, apresentação clínica, diagnóstico diferencial, avaliação por imagem, história natural, opções de tratamento e complicações. Nível de evidência III; Artigo de revisão.

ABSTRACT

ABSTRACT Objective To compare radiographic findings of patients who underwent laminoplasty and laminectomy with arthrodesis for spondylotic cervical myelopathy. Methods Who were submitted to laminectomy with arthrodesis or laminoplasty to treat cervical spondylotic myelopathy with minimum follow-up of 6 months. The radiographic parameters related to the cervical spine evaluated were C0C2 lordosis (C0C2), cervical lordosis (CL), T1 slope (T1S), thoracic inlet angle (TIA), neck tilt (NT), cervical sagittal vertical axis (CSVA), and T1S - CL mismatch (T1S-CL). Results We evaluated 34 patients, 23 (68%) of whom were men. The mean age was 65 years (SD ± 13). There was no statistical difference in any of the preoperative radiographic parameters. Considering the patients submitted to laminectomy alone, a significant difference was observed for C0C2 (P = 0.045), CSVA (P = 0.0008), with differences between IPO and POS times (P = 0.026) and between PRE and POS (P = 0.0013) and T1S - CL mismatch (P = 0.0004), with a difference between IPO and POS (P = 0.0076) and between PRE and POS (P=0.001). Considering the patients submitted to laminoplasty alone, there was no difference over time for any radiographic parameters considered. Comparing the radiographic parameters between the laminectomy and laminoplasty groups in the three time periods, there was no significant difference for any of them. Conclusion This study suggests that patients with cervical spondylotic myelopathy who underwent laminectomy with instrumentation may present worse radiographic evolution as regards cervical sagittal alignment over time when compared to patients who underwent laminoplasty. Level of evidence III; Retrospective case series.

Métodos Pacientes submetidos à laminectomia e artrodese ou laminoplastia para o tratamento de mielopatia cervical espondilótica com acompanhamento mínimo de seis meses. Os parâmetros radiográficos relacionados à coluna cervical avaliados foram: Lordose C0C2 (C0C2); Lordose cervical (LC); Inclinação de T1 (IT1); Ângulo de entrada do tórax (AET); Versão do pescoço (VP); Eixo sagital vertical cervical (ESVC); Diferença entre IT1 e LC (IT1-LC). Resultados Avaliaram-se 34 pacientes, sendo 23 (68%) homens. A idade média foi de 65 anos (DP: ±13). Não houve diferença estatística em nenhum dos parâmetros radiográficos pré-operatórios. Considerando isoladamente os pacientes submetidos à laminectomia, notou-se diferença significativa C0-C2 (P = 0,045), ESVC (P = 0,0008), sendo observada diferença entre os tempos POI e POS (P = 0,026) e entre PRE e POS (P = 0,0013) e diferença IT1 - LC (P = 0,0004) com diferença entre POI e POS (P = 0,0076) e entre PRE e POS (0,001). Considerando isoladamente os pacientes submetidos à laminoplastia, não houve diferença ao longo do tempo para nenhum dos parâmetros considerados. Comparando-se os parâmetros radiográficos entre os grupos laminectomia e laminoplastia nos três tempos, não houve diferença significativa para nenhum deles. Conclusões O estudo sugere que os pacientes portadores de mielopatia cervical submetidos a laminectomia com instrumentação possam apresentar pior evolução radiográfica quanto ao alinhamento sagital cervical ao longo do tempo quando comparados aos pacientes submetidos a laminoplastia. Nível de evid ê ncia III; Série de casos retrospectiva.

ABSTRACT

ABSTRACT The objective of this study was to discuss the three main surgical techniques currently applied in the treatment of degenerative cervical discopathy and their repercussions on patient quality of life. We considered the impact of the surgical techniques applied to the quality of life of 24 patients who underwent surgery during the period from 2010 to 2017 using the Oswestry and SF-36 scales. With the application of the questionnaires we observed, through the applicability and analysis of the quality of life results indicated in the questionnaires, that pain improvement and a reduction in work and daily activity disability were more effective with cervical arthroplasty. We concluded that with the individualization of surgical treatment, that is, through the choice of the surgical technique most appropriate for the clinical condition, the postoperative recovery and consequently the quality of life of the patient are enhanced. Level of evidence IV; Descriptive study.

ABSTRACT

BACKGROUND@#The optimal surgical approach for four-level cervical spondylotic myelopathy remains controversial. The purpose of this study was to compare clinical and radiological outcomes and complications between the anterior and posterior approaches for four-level cervical spondylotic myelopathy.@*METHODS@#A total of 19 patients underwent anterior decompression and fusion and 25 patients underwent posterior laminoplasty and instrumentation in this study. Perioperative information, intraoperative blood loss, clinical and radiological outcomes, and complications were recorded. Japanese Orthopedic Association (JOA) score, 36-item short form survey (SF-36) score and cervical alignment were assessed.@*RESULTS@#There were no significant differences in JOA scores between the anterior and posterior group preoperatively (11.6 ± 1.6 vs. 12.1 ± 1.5), immediately postoperatively (14.4 ± 1.1 vs. 13.8 ± 1.3), or at the last follow-up (14.6 ± 1.0 vs. 14.2 ± 1.1) (P > 0.05). The JOA scores significantly improved immediately postoperatively and at the last follow-up in both groups compared with their preoperative values. The recovery rate was significantly higher in the anterior group both immediately postoperatively and at the last follow-up. The SF-36 score was significantly higher in the anterior group at the last follow-up compared with the preoperative value (69.4 vs. 61.7). Imaging revealed that there was no significant difference in the Cobb angle at C2-C7 between the two groups preoperatively (-2.0° ± 7.3° vs. -1.4° ± 7.5°). The Cobb angle significantly improved immediately postoperatively (12.3° ± 4.2° vs. 9.2° ± 3.6°) and at the last follow-up (12.4° ± 3.5° vs. 9.0° ± 2.6°) in both groups compared with their preoperative values (P = 0.00). Three patients had temporary dysphagia in the anterior group and four patients had persistent axial symptoms in the posterior group.@*CONCLUSIONS@#Both the anterior and posterior approaches were effective in treating four-level cervical spondylotic myelopathy in terms of neurological clinical outcomes and radiological features. However, the JOA score recovery rate and SF-36 score in the anterior group were significantly higher. Persistent axial pain could be a major concern when undertaking the posterior approach.

ABSTRACT

OBJECTIVE@#To explore the clinical efficacy and safety of posterior intervertebral foraminal discectomy via Delta channel for cervical spondylotic radiculopathy in the early phase.@*METHODS@#From September 2017 to July 2018, 10 patients with cervical spondylotic radiculopathy underwent posterior intervertebral foraminal discectomy via Delta channel. There were 6 males and 4 females, aged from 30 to 62 years old with an average of (41.5±4.3) years old. All of them had unilateral symptoms caused by cervical nerve root compression, including 2 cases of C, 5 cases of C and 3 cases of C. CT and MRI examination of all the patients did not show ossification of posterior longitudinal ligament or calcification of ligamentum flavum, and no cervical spine instability was present in dynamic radiographs. The clinical outcome was poor after more than 6 weeks of systematic non-surgical treatment. The VAS score, JOA score, NDI score, the cervical spine physiological curvature, and the height and stability of the compressed cervical vertebrae were measured before operation and at the latest follow-up.@*RESULTS@#All patients successfully completed the surgeries without any spinal cord, nerve root or major blood vessel injury. The operation time was 70 to 120 min with an average of 90 min. Intraoperative blood loss ranged from 30 to 90 ml with an average of 40 ml. All the 10 patients were followed up for 6 to 14 months with an average of 9 months. Postoperative nerve root pain got relievd and nerve function was improved in all patients. VAS score decreased from 7.15±2.01 before surgery to 1.59±0.83 at the latest follow-up;JOA score increased from 12.57±1.24 before surgery to 16.42±0.58 at the latest follow-up;NDI score increased from 41.82±4.71 before surgery to 9.59±3.52 at the latest follow-up. All the results above presented significant difference between latest follow-up and preoperative (0.05). At the latest follow-up, no cervical instability was observed on dynamic radiographs.@*CONCLUSION@#Treatment of cervical spondylotic radiculopathy by posterior intervertebral foraminal discectomy via Delta channel can obtain a satisfactory clinical outcome without affecting the stability of cervical vertebra. The surgery is safe, reliable and worthy of clinical application.

ABSTRACT

OBJECTIVE@#To study the therapeutic effects of the ultramicro needle-knife combine with cervical spine fine adjusting on youth cervical curvature abnormality case.@*METHODS@#From November 2016 to October 2018, 88 young patients with abnormal curvature of cervical spine were treated. Due to loss of follow up, 86 cases were actually completely including 37 males and 49 females, ranging in age from 20 to 40 years old, with an average of (30.55±5.21) years old, and the course of disease ranged from 1 to 42 months, with a mean of (14.21±7.38) months. All the patients were divided into two groups:treatment group (44 cases) and control group (42 cases). The patients in the treatment group were treated with ultramicro needle-knife and cervical spine fine adjusting, and the patients in the control group were treated with conventional acupuncture and manipulation. The treatments were done 1 time per week in the treatment group while 3 times per week in control group every week, with a duration of 3 weeks for both groups. Before treatment, 3 weeks after treatment, and at the end of 1 month follow-up, the score of neck pain questionnaire(NPQ), range of the motion(ROM) in the cervical region and the D values of cervical physiological curvature were recorded. The efficacy at the end of treatment and in the follow up was evaluated. During the treatment, the patients were also required to correct the bad posture in daily life, to sleep in a low pillow position, and put a moderately columnar pillow behind the neck for 0.5 hours every morning and evening.@*RESULTS@#Two patients in the control group were dropped out after 3 weeks treatment. No adverse reactions were found in the 2 groups during the treatment period. Compared with those before treatment, all scores at all the observation time points were significantly improved between two groups after treatment(all 0.05). There was statistical difference in ROM scores between different time points, there was time effect (=240.32), =0.000). There was no interaction between time factor and group factor (=0.311, =0.734). The effective rate of the treatment group and control group were 90.91%(40 / 44) and 80.95%(34 / 42) respectively, the treatment group was more effective than the control group (0.05) in the follow-up duration.@*CONCLUSION@#The method of needle knife combined with cervical spine fine adjusting has a better therapeutic efficiency than conventional acupuncturecombined with manipulation in treating youth cervical curvature abnormality patients. Because this novel method can recover the cervical curvature, relieve the neck pain, and improve cervical mobility.

ABSTRACT

Xiaoxuming Decoction is an ancient classic herbal formula for the treatment of stroke. In ancient times, the connotation of stroke was very extensive, including facial neuritis, acute cerebral infarction, acute cerebral hemorrhage, sequelae of cerebral hemorrhage, unexplained weakness of limbs, cervical spondylosis, acute myelitis, acute radiculitis, Guillain Barre syndrome, multiple sclerosis, myasthenia gravis, motor neuron disease, dermatomyositis, hypokalemic paralysis peripheral neuritis. It has been identified that: ①Xiaoxuming Decoction is very common in the treatment of cerebrovascular diseases, such as cerebral infarction, cerebral hemorrhage and other cerebrovascular diseases, facial neuritis, acute myelitis, acute radiculitis, Guillain Barre syndrome, unexplained limb weakness, multiple sclerosis, motor neuron disease, myasthenia gravis, and rheumatic and immune system diseases, such as dermatomyositis, and can not only alleviate symptoms, but also improve prognosis and the long-term survival rate. ②Sudden limb failure, facial paralysis, and hypoalgesia without heat syndrome are the key indications of Xiaoxuming Decoction. ③This is a special prescription for the treatment of acute facial neuritis, and can cure in one week in the combination with moxibustion. ④In the treatment of facial neuritis complicated with hypertension or acute cerebrovascular disease, Xiaoxuming Decoction generally has a certain antihypertensive effect, without any hypertensive effect, which reflected its two-way regulatory effect for blood pressure. ⑤In the treatment of unknown limb weakness, acute myelitis, acute radiculitis, Guillain Barre syndrome, Xiaoxuming Decoction can rapidly alleviate the symptoms. ⑥This is the basic formula for multiple sclerosis and motor neuron disease. Long term use of Xiaoxuming Decoction can alleviate the symptom of limb weakness, reduce the occurrence of complications and delay the progress of the disease, but with a poor long-term prognosis. ⑦In the treatment of myasthenia gravis, Xiaoxuming Decoction can significantly improve muscle strength, and gradually help stop hormone reduction. After thymoma surgery, Xiaoxuming Decoction is also applicable to some patients with recurrent myasthenia gravis. ⑧Xiaoxuming Decoction also plays a role in the treatment of dermatomyositis and cervical spondylopathy. ⑨Raw ephedra is the monarch drug of Xiaoxuming Decoction, which is the key to the effect. The dosage starts with 6 g is titrated in a small dose and increases gradually. In addition, this formula is forbidden for those with red face, fast heart rate, high blood pressure, blocked stool, red tongue, yellow fur, wiry and rapid pulse or powerful pulse, and spout pulse.

ABSTRACT

BACKGROUND@#Neck pain caused by cervical spondylosis (CS) is a chronic pain condition, with an increasingly high incidence in the general population. Electroacupuncture is a common analgesic modality that has been widely applied in neck pain treatment. However, current electroacupuncture instruments used in the clinic have low intelligence levels and obscure parameter standards. We here designed this study for assessing the effect and safety of a new, intelligent electroacupuncture instrument, the CX-DZ-II, in treating neck pain.@*METHODS@#The present study is a prospective, two-center, randomized, controlled, open-label, non-inferiority trial for CX-DZ-II on treating neck pain caused by CS. Totally 160 eligible patients will be included in this trial and randomly assigned to an experimental group and a control group in a 1:1 ratio. A semi-standard acupoint selection strategy will be employed. In the experimental group, selected acupoints will be stimulated by CX-DZ-II. Electroacupuncture treatment will be accomplished by a pre-existing electroacupuncture instrument in the control group. The duration of treatment will be 2 weeks. The primary outcome is the change of Visual Analog Scale (VAS) score after one course of treatment. The secondary outcomes include the VAS scores after each treatment, the responder rate, drug-usage rate of non-steroidal antipyretic analgesics, the rate of adverse events occurrence, and the performance of instrument.@*DISCUSSION@#This study will evaluate the effect and safety of the CX-DZ-II intelligent electroacupuncture therapeutic instrument in comparison with a pre-existing non-intelligent instrument in the treatment of neck pain caused by CS. The results will hopefully demonstrate a more optimal electroacupuncture instrument for the treatment of neck pain. (Trial registration No. gov NCT03005301).

ABSTRACT

OBJECTIVES@#Quantitative magnetic resonance imaging has been successfully applied to assess the status of cartilage biochemical components. This study aimed to investigate the performance of 3.0T magnetic resonance imaging T mapping combined with texture analysis for evaluating the early degeneration of lumbar facet joints.@*METHODS@#A total of 38 patients (20 in the asymptomatic group and 18 in the symptomatic group) were enrolled. All patients underwent 3.0T magnetic resonance imaging conventional sequences, water excitation three-dimensional spoiled gradient echo sequence (3D-WATSc), and T mapping scans. The bilateral L and L/S lumbar facet joints were morphological graded using the Weishaupt criteria, T values, and texture parameters derived from T mapping of cartilage. The Kruskal-Wallis test was used to compare the differences of parameters among different groups. Multivariate logistic regression analysis was used to obtain the independent predictive factors for evaluating the early degeneration of lumbar facet joints. Receiver operating characteristic (ROC) curve was performed and the area under curve (AUC) was calculated. Spearman correlation analysis was used to evaluate the correlation of the independent predictors of cartilage T value and texture parameters with the subjects' Japanese Orthopedic Association (JOA) score or Visual Analogue Scale (VAS) score.@*RESULTS@#A total of 148 facet joints were selected, including 70 in Weishaupt 0 (normal) group, 58 in Weishaupt 1 group, and 20 in Weishaupt 2-3 group. T value, entropy, and contrast increased significantly as the exacerbation of facet joint degeneration (all <0.05), while the inverse difference moment, energy, and correlation decreased (all <0.05). Entropy among different groups was significantly different (all <0.05), and the differences of T value, contrast, inverse difference moment, and energy between Weishaupt 0 and Weishaupt 1 groups, or Weishaupt 0 and Weishaupt 2-3 groups were statistically significant (all <0.05). Multivariate logistic regression analysis suggested that T value and inverse difference moment were the independent predictors for evaluating early degeneration of facet joints. The combination of T value with inverse difference moment achieved the best performance in distinguishing Weishaupt 0 from Weishaupt 1 (AUC=0.85), with sensitivity and specificity at 92.7% and 76.5%, respectively. In the symptom group, the cartilage T value combined inverse difference moment was positively correlated with JOA score (=0.475, <0.05) and VAS score (=0.452, <0.05).@*CONCLUSIONS@#3.0T magnetic resonance imaging T mapping combined with texture analysis is helpful to quantitatively evaluate the early degeneration of lumbar facet joints, in which the T value and inverse difference moment show an indicative significance..
