Objective:A meta-analysis was performed to evaluate the difference of curative effect of Huoxue huayu Chinese medicine compound combined with intervertebral pore lens in the treatment of lumbar disc herniation.Methods:CNKI,VIP,CBM,PubMed and Web of Science were searched by computer and included in the clinical trial data about the treatment of lumbar disc herniation by the Huoxue huayu Chinese medicine compound and intervertebral pore lens.Data were extracted and Cochrane system was used to evaluate the quality of the study.Cochrane system in ReMan 5.1 was used to evaluate the publication bias and Stata 12.0 was used for meta analysis.Results:A total of 1039 patients were included in 16 articles,including 519 patients in the treatment group and 520 patients in the control group.The results showed that the total effective rate of the treatment group was higher than that of the control group(RR=1.20,95%CI(1.11,1.30),P<0.05);The excellent rate of the treatment group was higher than that of the control group(RR=1.20,95%CI(1.08,1.32),P<0.05);The JOA score of the treatment group was higher than that of the control group(MD=3.39,95%CI(1.90,4.87),P<0.00001);the VAS score of the treatment group was lower than that of the control group(MD=-1.13,95%CI(-1.84,-0.42),P=0.002);The ODI score of the treatment group was lower than that of the control group[MD=-3.34,95%CI(-4.49,-2.19),P<0.00001].Conclusion:Huoxue huayu Chinese medicine compound and intervertebral pore lens can improve the clinical effect and is worth popularizing.However,due to the poor quality of the literature,more high-quality double-blind randomized controlled trials with large samples are needed.

Early efficacy of endoscopic translaminar and intervertebral foraminal approaches in the treatment of lumbar disc herniation

Objective:To investigate the early efficacy of two approaches for lumbar disc herniation under spinal endoscopy.Methods:45 cases of lumbar disc herniation were divided into interlaminar approach(27 cases)and intervertebral foramen approach(18 cases)according to different surgical approaches.Postoperative pain visual analogue scale(VAS)was used.Japanese Orthopaedic Association(JOA)lumbar spine score(JOA)and modified Macnab criteria were used to evaluate the postoperative outcome.Results:(1)VAS score.There is no interaction effect between the access mode and the time factor(F=0.620,P=0.603).There were statistically significant differences in pain VAS scores between preoperative and postoperative time points,that is,there was a time effect(F=2157.488,P=0.000).The overall VAS scores of the two groups were compared,and the difference was not statistically significant,that is,there was no grouping effect(F=2.610,P=0.114).The VAS score of pain in both groups decreased with time,and the differences between the two groups were not statistically significant before surgery,at discharge,1 month after surgery and 3 months after surgery(t=0.067,P=0.947;t=1.415,P=0.164;t=0.564,P=0.575;t=0.442,P=0.660);JOA score.There is no interaction effect between the access mode and the time factor(F=1.296,P=0.280).The difference of JOA score between preoperative and postoperative time points was statistically significant,that is,there was a time effect(F=1464.830,P=0.000).JOA scores of the two groups showed an increasing trend with time,and the differences between the two groups were not statistically significant before surgery,at discharge,1 month after surgery and 3 months after surgery(t=0.067,P=0.947;t=1.415,P=0.164;t=0.564,P=0.575;t=0.442,P=0.660);(2)The improved Macnab standard was used to evaluate the excellent and good rate at 3 months after surgery.In the interlaminar group,12 cases were excellent,13 cases were good and 2 cases were fair.The excellent and good rate was 92.6%.In the intervertebral foramen group,7 cases were excellent,10 cases were good and 1 case was fair.The excellent and good rate was 94.4%.The overall excellent and good rate of the two groups was 93.3%.Conclusion:Both approaches can achieve satisfactory efficacy in the treatment of lumbar intervertebral disc herniation,which is worthy of clinical application.However,for beginners,l5-s1 lumbar disc herniation is more suitable for intervertebral disc approach,so as to achieve satisfactory efficacy.

Apparent diffusion coefficient in normal and abnormal pattern of intervertebral lumbar discs: initial experience

The aim of the present study was to compare the relationship of morphologically defined non-bulging/herni-ated, bulging and herniated intervertebral lumbar discs with quantitative apparent diffusion coefficient （ADC）. Thirty-two healthy volunteers and 28 patients with back pain or sciatica were examined by MRI. All intervertebral lumbar discs from L1 to S1 were classified according to morphological abnormality and degenerated grades. The ADC values of nucleus pulposus （NP） were measured and recorded. The significant differences about mean ADC values of NP were found between non-bulging/herniated discs and bulging discs as well as herniated discs （P 0.05）, whereas there were no significant differences in ADC values between bulging and herniated discs （P 0.05）. Moreover, statistically significant relationship was found in the mean ADC values of NP between ＂non-bulging/herniated and non-degenerated discs＂ and ＂non-bulging/herniated degenerated discs＂ as well as herniated discs （P 0.05）. Linear regression analysis between ADC value and disc level revealed an inverse correlation （r = -0.18）. The ADC map of the NP is a potentially useful tool for the quantitative assessment of componential and molecular alterations accompanied with lumbar disc abnormalities.

Comparison of microendoscopic discectomy and open discectomy for single-segment lumbar disc herniation

BACKGROUND Lumbar disc herniation is a common disease.Endoscopic treatment may have more advantages than traditional surgery.AIM To compare the clinical efficacy and safety of microendoscopic discectomy(MED)and open discectomy with lamina nucleus enucleation in the treatment of singlesegment lumbar intervertebral disc herniation.METHODS Ninety-six patients who were operated at our hospital were selected for this study.Patients with single-segment lumbar disc herniation were admitted to the hospital from March 2018 to March 2019 and were randomly divided into the observation group and the control group with 48 cases in each group.The former group underwent lumbar discectomy and the latter underwent laparotomy and nucleus pulpectomy.Surgical effects were compared between the two groups.RESULTS In terms of surgical indicators,the observation group had a longer operation time,shorter postoperative bedtime and hospital stay,less intraoperative blood loss,and smaller incision length than the control group(P<0.05).The excellent recovery rate did not differ significantly between the observation group(93.75%)and the control group(91.67%).Visual analogue scale pain scores were significantly lower in the observation group than in the control group at 1 d,3 d,1 mo,and 6 mo after surgery(P<0.05).The incidence of complications was significantly lower in the observation group than in the control group(6.25%vs 22.92%,P<0.05).CONCLUSION Both MED and open discectomy can effectively improve single-segment lumbar disc herniation,but MED is associated with less trauma,less bleeding,and a lower incidence of complications.

Isolation of <i>Gemella morbillorum</i>in Herniated Intervertebral Disc Tissue in a Lumbar Discectomy Patient: A Case Report

Back pain associated with lumbar disc herniation is a common musculoskeletal disorder that leads to absence at work place worldwide. Studies have proven in addition to the traditional factors, microbes play a role in disc herniation causing chronic back pain. A 34-year-old male who has not involved in any traumatic work but has a family history of disc herniation presented with lower back pain and numbness in his right leg. He had previously undergone lumbar discectomy at L4/L5 ten years back. Magnetic Resonance Imaging (MRI) showed L5/S1 right para central disc herniation impinging on the right S1 and S2 nerve roots. Standard protocols for disinfection of instruments, external skin and all transport media were adhered. Skin scrapings, muscle biopsy and excised disc tissue were obtained for anaerobic and aerobic bacterial cultures. Anaerobic microbial cultures of excised disc tissue following lumbar discectomy showed Gram positive growth. Further anaerobic isolation carried out using RapID ANA ID kit confirmed the growth as Gemella morbillorum. In addition, neither of the control samples (muscle nor skin) had any anaerobic growth indicating the absence of contamination. Aerobic bacterial growth was not present in the skin, muscles and disc cultures. The study findings add to the available literature, on the role of microorganisms in lumbar disc herniation and future treatment regimens with antibiotics.

The Clinical Outcomes of Transforaminal Percutaneous Endoscopic Discectomy in Treating Lumbar Disc Herniation: A Review

Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive technique started during the late 20th century. This process is done through microscopic view under local anesthesia. There is a growing but still insufficient evidence that lumbar EDS shows slightly better results in terms of minor tissue damage, shorter hospital stay, faster return to ordinary daily activities, and patient satisfaction. Recurrence rate still remains a matter of debate, and is related with the surgical skills of the surgeon. The complication rate seems to be similar in both of the techniques i.e., open and endoscopic. More randomized controlled trials, systematic reviews and meta-analysis are needed to clarify whether lumbar EDS can be considered comparable if not superior to standard open discectomy. In spite of lacking defined clinical evidence, lumbar EDS is without doubt a rapidly expanding PELD and its future developments are incredibly promising. Due to less complication rate this technique can be considered as a gold standard compared to the open discectomy. The surgeons still require more cadaveric practices for learning the curve and to approach the herniated disc area. The main objective of this review article is to show the clinical outcomes of the Transforaminal Percutaneous Endoscopic Discectomy in treating the lumbar disc herniation.

Applied anatomy of intrusive operations of lumbar intervertebral foramen

Objective:To provide anatomical datum for intrusive operations of lumbar intervertebral foramen,especially that using acupuncture-knife as intrusive tool.Methods:To dissect 10 antisepsis cadavers and observe the exposed blood vessels,ligaments,nerves and their adjacent relations in L1/2~L5/S1intervertebral foramen.Results:Lumbar intervertebral foramen exit zones were almost sealed by nerves and blood vessels.There were two zones with relatively no blood vessel and nerve(triangular working zones)located in the midpoint of the distance between two adjacent roots of transverse processus,and clung to lamina of vertebral arch,and they were also found upon the margo superior of the root of transverse processus,but the ascending lumbar vein or(and)the rami anastomoticus between the remi inferior of intervertebral vein and lumbar veins were observed in 12%triangular working zones upon the margo superior of root of transverse processus.Conclusions:"Triangular working zone"was relatively avascular zone.Pay attention to the possibilty of presence of blood vessels on the entrance passage of intrusive operations on lumbar side rear.The needlepoint should be pierced at the midpoint of the distance between two adjacent roots of transverse processus and cling to the outer edge of lamina of vertebral arch when doing the foraminal lumbar puncture.As lumbar intervertebral foramina exit zone was almost sealed by nerves and blood vessels,blind incising and debonding with acupuncture-knife in this area was relatively much more dangerous.

目的探讨术前白细胞介素-6/白介素-10表达对腰椎间盘突出症术后椎间隙感染的预测价值。方法采用病例对照研究,收集医院2021年1月至2023年1月收治的24例腰椎间盘突出症术后发生椎间隙感染患者的临床资料,纳入发生组,另收集医院同期48例未发生术后椎间隙感染的腰椎间盘症患者临床资料,纳入未发生组。通过查阅腰椎间盘突出症患者病历资料记录基线资料,同时收集所有患者术前白介素-6、白介素-10值,并计算白介素-6/白介素-10值。通过受试者工作曲线(ROC),探讨术前白细胞介素-6/白介素-10表达对腰椎间盘突出症术后椎间隙感染的预测价值。结果发生组住院时间、术前白细胞介素-6、术前白细胞介素-10、术前及术后白细胞介素-6/白细胞介素-10水平大于未发生组,差异有统计学意义(P<0.05)。经点二列相关性结果显示,术前白介素-6、术前白介素-10、术前白介素-6/白介素-10与腰椎间盘突出症术后椎间隙感染发生呈正相关(r>0,P<0.05)。绘制ROC曲线,结果显示,术前白介素-6/白介素-10预测腰椎间盘突出症术后椎间隙感染发生的曲线下面积(AUC)为0.723,具有一定预测效能。结论术前白细胞介素-6/白介素-10表达对腰椎间盘突出症术后椎间隙感染发生具有较好预测效能,其值越高术后椎间隙感染发生可能性越大。

椎间融合术治疗腰椎间盘突出症术后复发的临床研究

目的:探究不同椎间融合器(cage)治疗术后复发的腰椎间盘突出症(lumbar disc herniation,LDH)的临床疗效。方法:回顾性分析2019年1月至2021年1月142例行单纯椎间盘髓核摘除术后复发的LDH患者,均采用通道下联合固定并椎间融合术治疗,根据植入cage类型及数目不同分为单枚解剖组、2枚解剖组和单枚香蕉组。单枚解剖组51例,男29例,女22例;年龄39~65(53.74±5.68)岁;身体质量指数(body mass index,BMI)18.62~28.13(22.08±2.15)kg·m-2;手术与复发间隔时间0.5~4.0(2.7±0.8)年;L3,45例,L4,535例,L5S111例;植入单枚解剖型cage。2枚解剖组46例,男25例,女21例;年龄37~66(54.15±6.02)岁;BMI为18.25~28.44(21.74±1.83)kg·m-2;手术与复发间隔时间0.5~5.0(2.7±0.9)年;L3,44例,L4,532例,L5S110例;植入2枚解剖型cage。单枚香蕉组45例,男22例,女23例;年龄38~65(54.49±6.45)岁;BMI为18.85~28.20(21.63±1.59)kg·m-2;手术与复发间隔时间0.5~5.0(2.6±1.0)年;L3,43例,L4,536例,L5S16例;植入单枚香蕉型cage。观察并比较3组手术时间、术中出血量、切口长度、术后切口引流量、住院时间、并发症等情况;比较手术前后椎间隙高度、前凸曲度及术后椎间融合情况;分别于术前、术后1和6个月采用视觉模拟评分(visual analogue scale,VAS)和Oswestry功能障碍指数(Oswestry disability index,ODI)对腰部疼痛程度、腰椎功能进行临床疗效评价。结果:3组患者均获得至少6个月随访,无病例脱落。3组手术时间、术中出血量、切口长度、术后切口引流量、住院时间比较,差异无统计学意义(P>0.05)。2枚解剖组、单枚香蕉组术后6个月融合节段椎间隙高度[(11.08±1.78)mm、(10.95±1.62)mm]、前凸曲度[(12.05±1.86)°、(11.63±1.57)°],高于单枚解剖组(10.14±1.54)mm、(10.92±1.45)°,差异有统计学意义(P<0.05);2枚解剖组、单枚香蕉组术后6个月椎间融合率(95.65%、95.56%),高于单枚解剖组(78.43%);3组术后1、6个月腰部VAS、ODI较术前下降(P<0.05);3组并发症比较,差异无统计学意义(P>0.05)。结论:3种融合器治疗LDH术后复发均能取得显著效果,但植入2枚解剖型cage和单枚香蕉型cage更有助于维持LDH术后复发患者椎间隙高度、前凸曲度,可获得良好椎间融合效果。
