Abstract Background: Plain radiographs are rarely used in the diagnostic evaluation of lumbar disc herniation (LDH). The L5 lamina is the important skeletal structure at the back of the lower lumbar vertebra. This study investigated the association between the height of L5 lamina under anteroposterior lumbar spine X-ray and lower LDH, to determine its significance to the onset of LDH in young adults.Methods: We conducted a retrospective study of 160 patients aged 18 to 39 years with lower LDH and 160 healthy controls. The anteroposterior lumbar spine X-ray was used to image features of the L5 lamina. The height of L5 lamina (“h”) and of the space between L4 and S1 lamina (“H”) were measured. The difference in height of L5 lamina in each study group was assessed as the ratio of “h/H”. Results: There was no significant difference in sex, age, occupation type, body mass index (BMI), family history or smoking status (p>0.05) between LDH group and the control group. The mean ratio (95% CI) of “h/H” in LDH and control group was 0.28 (0.26, 0.31) and 0.35 (0.32, 0.38) respectively, with statistical difference (p<0.05). The diagnostic accuracy of “h/H” ratio was investigated using the receiver operating characteristic (ROC) curve. The area under the curve was 0.835 (95% CI 0.789, 0.881), using a cut-off of 0.315 (sensitivity 0.806, specificity 0.794). A decrease in the “h/H” ratio, showed an increasing linear trend in the protrusion proportion of L4/5 segments (Z=5.943, p<0.05).Conclusions: The onset of lower LDH in young adults is related to the developmental difference in L5 Lamina. Young adults with developmental defects of L5 lamina are more likely to develop lower LDH. Assessment of “h/H” ratio could be used for evaluation or prediction of asymptomatic or mildly symptomatic lower LDH in young adults.

Objective: Lumbar disc herniation leads the numbness and pain in the waist and lower limbs. Intervertebral foramen endoscopy is a minimally invasive procedure for the treatment of disc herniation. Adequate preoperative evaluation is conducive to this percutaneous skin surgery. The purpose of this study is to improve the efficacy of intervertebral foramen endoscopy in the treatment of lumbar disc herniation by preoperative computer three-dimensional reconstruction combined with pain management. Method: Fifty patients with lumbar disc herniation who met the indications of intervertebral foramen endoscopy were randomly divided into experimental group and control group. The control group was operated according to experience based on the common axial image. The experimental group was punctured according for three-dimensional visualization model of lumbar spine. Preoperative simulated puncture catheterization and perioperative pain management was applied. The catheterization time, operation time under endoscopy, fluoroscopy times during operation, the Visual Analogue Scale (VAS) and Japanese Orthopaedic Association (JOA) scores before and 1 d, 1 m and 3 m after operation were compared between two groups. Result: The three-dimensional visualization model of lumbar spine was reconstructed based on thin-layer data. According to the results of software measurement, the skin puncture point was located and the puncture angle was obtained. Compared with the control group, the catheterization time, operation time under endoscopy, fluoroscopy times during operation in experimental group were significantly reduced. There was no statistical difference in VAS and JOA scores between two groups before operation. Compared with control group, the VAS scores in experimental group at 1 d, and 1 m after operation were decreased statistically, while the JOA scores were increased statistically. Conclusion: Three-dimensional visualization model of lumbar spine and virtual operation planning can directly judge the feasibility of intervertebral foramen endoscopy in the treatment of lumbar disc herniation, improve the efficiency of operation, and further improve postoperative efficacy with pain management.

Traction Is Part Of The Evidence Based Manual Physical Therapy Management Due To Its Mechanical Nature. The Efficacy Of Lumbar Traction (Lt) Has Been Established, Lt As The Most Used Method Of Spinal Decompression Therapy (Sdt) Reduces The Intradiscal Pressure And Vertically Increases The Intervertebral Space And Restore Disc Height Allowing Nutrients And Oxygen Supply To The Disc. While Lt Had Recently Been Used As A Conservative Treatment For Chronic Lumbar Disc Herniation (Cldh), Combined Lumbar Traction With Cervical Traction (Cltct) As One Intervention Which Has Been Suggested By (Al-Qudah, M.K) Was Used As A Part Of Rehabilitative Program In Patients With Cldh. Therefore, The Effectiveness Of Cltct Separately At Any Other Interventions Remains Absolutely Unclear And Uncertain. Objective: The Aim Of The Presented Work Is To Identify The Effectiveness Of Cltct [(Positional Sustained Lumbar Traction (Pslt) Combined With Mechanical Sustained Cervical Traction (Msct) As One Intervention] On Patients With Moderate (L4-L5) (L5-S1) Cldh, And To Compare Cltct With Traditional Mechanical Lumbar Traction (Mlt). Methods: In This Study, Twelve Outdoor Male Patients Diagnosed With Magnetic Resonance Imaging (Mri), Had Accepted To Participate The Study. They Were Chosen From Al-Karak Governmental Hospital, From 20th Of December To 1st February 2021. Subjects Were Divided Randomly In To Two Groups, Experimental Group (N=6) Performed Cupping Massage (Cm), Cltct And Core Stabilization Exercise (Cse), While The Control Group (N=6) Performed Cm, Mlt And Cse. All Subjects Were Advised To   Perform The Cse Three Times Daily As A Home Program In Addition To One Set During Each Session Under The Therapist Supervision. All Subjects Had Exposed (18) Sessions For (6) Weeks. The Results Were Analyzed Using The Spss System. Results: Indicates That There Was Statistically Significant Difference Between The Pre And Post Measurements In Both Groups In Favor Of The Post Measurements In Term Of Pain And Disability. Also Results Indicate That There Was Statistically Significant Difference Between The Groups In Favor Of Experimental Group. Conclusions: The Present Study Demonstrates That The Use Of Cltct Has A Positive Effect On Patients With Cldh More Than Mlt.

Abstract Background: Contrast-enhanced lumbar spine magnetic resonance imaging (MRI) was used to predict the efficacy of conservative treatment of giant lumbar disc herniation.Methods: From June 2017 to June 2019, 30 patients with giant lumbar disc herniation with positive and negative bull’s eye signs on contrast-enhanced lumbar spine MRI were assessed to measure differences in the rate of intervertebral disc herniation, rate of protrusion absorption, treatment effect, protrusion rate, and curative effect according to the lumbar Japanese Orthopedic Association (JOA) score before and after treatment.Results: Thirty patients with positive and negative bull’s eye signs (36 men and 24 women) aged 19 to 58 years (mean, 36.37 ± 9.56 years) were included. All patients were followed up for more than 1 year, and at least one MRI review was conducted within 1 year of treatment. The results of the first and final MRI examinations were compared. The protrusion rate was 82.16% ± 14.58% before treatment and 32.20% ± 30.80% after treatment, and the absorptivity of the protrusion was 59.48% ± 38.62%. There was no statistically significant difference in the general data before treatment between the positive and negative groups (P > 0.05). After treatment, the protrusion rate in the positive and negative bull’s eye sign groups was 14.41% ± 14.37% and 49.99% ± 32.70%, respectively (P < 0.05). The absorptivity in the positive and negative bull’s eye sign groups was 83.09% ± 15.54% and 35.87% ± 40.49%, respectively (P < 0.05). There was no statistically significant difference in the JOA score between the two groups before treatment (P > 0.05); however, there was a statistically significant difference in the JOA score between the two groups at 3 months (P < 0.05) and 1 year (P < 0.05) after treatment.Conclusions: Conservative treatment of giant lumbar disc herniation has a satisfactory clinical effect. Contrast-enhanced MRI can be used to predict the resorption of giant lumbar disc herniation. Protrusion resorption is more likely to occur in patients with than without a bull’s eye sign.Trial registration: Chinese Clinical Trial Registry (No. ChiCTR1900022377).

AimsThe purpose of this study was to investigate the risk of additional surgery in the lumbar spine and to describe long-term changes in patient-reported outcomes after surgery for lumbar disc herniation in adolescents and young adults.Patients and MethodsWe conducted a retrospective study design on prospectively collected data from a national quality register. The 4537 patients were divided into two groups: adolescents (≤ 18 years old, n = 151) and young adults (19 to 39 years old, n = 4386). The risk of additional lumbar spine surgery was surveyed for a mean of 11.4 years (6.0 to 19.3) in all 4537 patients. Long-term patient-reported outcomes were available at a mean of 7.2 years (5.0 to 10.0) in up to 2716 patients and included satisfaction, global assessment for leg and back pain, Oswestry Disability Index, visual analogue scale for leg and back pain, EuroQol five-dimension questionnaire (EQ-5D), and 36-Item Short-Form Health Survey (SF-36) Mental Component Summary and Physical Component Summary scores. Statistical analyses were performed with Cox proportional hazard regression, chi-squared test, McNemar’s test, Welch–Satterthwaite t-test, and Wilcoxon’s signed-rank test.ResultsAny type of additional lumbar spine surgery was seen in 796 patients (18%). Surgery for lumbar disc herniation accounted for more than half of the additional surgeries. The risk of any additional surgery was 0.9 (95% confidence interval (CI) 0.6 to 1.4) and the risk of additional lumbar disc herniation surgery was 1.0 (0.6 to 1.7) in adolescents compared with the young adult group. Both age groups improved their patient-reported outcome data after surgery (all p < 0.001). Changes between short- (mean 1.9 years (1.0 to 2.0)) and long-term follow-up (mean 7.2 years (5.0 to 10.0)) were small.ConclusionThe risk of any additional lumbar spine surgery and additional lumbar disc herniation surgery was similar in adolescents and young adults. All patient-reported outcomes improved from preoperative to the short-term follow-up, while no likely clinically important differences between the short- and long-term follow-up were seen within both groups.

The aim was to explore the effect of lateral recess decompression by percutaneous transforaminal endoscopic spine system (Tessys) technique combined with percutaneous transforaminal endoscopic discectomy (PTED) on pain medium, nerve function and stress response in patients suffering from contralateral symptoms of lumbar disc herniation. A total of 96 patients with contralateral symptoms of lumbar disc herniation treated in our hospital from February 2015 to April 2017 were randomly divided into control group and study group, with 48 cases in each group. The control group underwent PTED, and the study group underwent lateral recess decompression by Tessys technique combined with PTED. The visual analogue scale (VSA) score and Japanese Orthopaedic Association (JOA) score before surgery and 3 months after surgery were compared between the two groups. The levels of serum pain medium (prostaglandin E2 (PGE2), histamine (HA), 5-hydroxytryptamine (5-HT)) and oxidative stress indexes (malondialdehyde (MDA), myeloperoxidase (MPO), superoxide dismutase (SOD), total antioxidant capacity (TAC)) before surgery and 7 days after surgery were compared. The clinical efficacy of the two groups was compared at 1 month after treatment. One month after treatment, the excellent and good rate in the study group was significantly higher than that in the control group (85.4% vs 56.3%; P < 0.05). There was no significant difference between VAS and JOA score in the two groups preoperatively ( P > 0.05). At 3 months after surgery, the VAS score in the study group was significantly lower than that in the control group ( P < 0.05), and the JOA score in the study group was significantly higher than that in the control group ( P < 0.05). There was no significant difference in serum PGE2, HA and 5-HT levels between the two groups preoperatively ( P > 0.05). At 7 days after surgery, the serum PGE2, HA and 5-HT levels in the study group were significantly lower than those in the control group ( P < 0.05). Preoperatively, the levels of serum MDA, MPO, SOD and TAC were not significantly different between the two groups ( P > 0.05). On the seventh day after surgery, the levels of serum MDA and MPO in the study group were significantly lower than those in the control group ( P < 0.05), and the levels of SOD and TAC were significantly higher than those in the control group ( P < 0.05). In conclusion, the combined therapy of lateral recess decompression by Tessys technique and PTED in patients suffering from contralateral symptoms of lumbar disc herniation has a definite clinical effect, which can significantly alleviate the symptoms of low back pain and motor nerve function and reduce the contents of serum pain medium and the levels of oxidative stress. It is worthy of clinical promotion.

Purpose: To investigate the association of facet joint asymmetry with lumbar disc herniation at the lower lumbar spine. Methods: A total of 90 patients (ages 18–40 years) with single-level disc herniation (L3–L4, L4–L5, or L5–S1) were included in the study. Facet asymmetry was defined as a difference of 10° in facet joint angles between right and left sides. Normal discs in the same segment of other individuals were used as a control. Patients had facet asymmetry measured for L3 to S1 through 3.0T magnetic resonance imaging, and information was collected, including age, sex, degenerative degree of lumbar facet joints, and the presence or absence of lumbar disc herniation and type. Results: At the L3 to L4 level, 2 cases had facet asymmetry in 8 patients with lumbar disc herniation, compared with 17 cases of facet asymmetry in 82 patients without disc herniation (P = 0.7776, r = 0.030). At the L4 to L5 level, there were 21 cases of facet asymmetry in 45 patients with lumbar disc herniation, compared with 5 cases of asymmetry in 45 patients without disc herniation (P = 0.00019, r = 0.392). At the L5 to S1 level, there were 25 cases of facet asymmetry in 37 patients with lumbar disc herniation, compared with 11 cases of facet asymmetry in 53 patients without disc herniation (P = 0.0000, r = 0.492). There were 23 cases of facet asymmetry in 28 disc herniations of side type compared with 2 cases of facet asymmetry in 9 herniations of center type (P = 0.0008, r = 0.364). There was no significant difference in the relationship between age, facet joint degeneration, and lumbar facet joint asymmetry (P &gt; 0.05). Conclusion: Facet asymmetry is significantly associated with lumbar disc herniation at the L4 to L5 and the L5 to S1 levels, whereas there is an obvious association with the side type of lumbar disc herniation at the L5 to S1 level.

Abstract Background: Percutaneous Transforaminal Endoscopic Discectomy is used increasingly in patients with Lumbar Disc Herniation. There is little knowledge on the related factors including SLR test influencing the operation. Therefore, we designed this prospective study to explore the relevant factors influencing postoperative effect of PTED surgery.Methods: Consecutive patients with LDH who came to our hospital from August 2015 to September 2016 and received PTED surgery. 4 kinds of scales including VAS (lumbar/leg), ODI and JOA were measured and reassessed at 1 day, 3 months, 6 months, 12months and 36 months after the PTED to assess their surgical outcomes. Results: All the patients had successful surgery. ODI and VAS (lumbar/leg) decreased in all patients and groups. And there was a statistically significant difference in each postoperative follow-up compared with that before surgery in every visit. In addition, the increase of JOA in postoperation was statistically significant compared with that before surgery. And, there is statistically significant difference between the three subpopulations (patients with SLR Positive (0°-30°), SLR Positive (31°-60°) and SLR Negative (61°-) in the changes of the scores of VAS(leg), ODI and JOA. However, there is no statistically significant difference between the three subpopulations (patients with SLR Positive (0°-30°), SLR Positive (31°-60°) and SLR Negative (61°--RRB- in the changes of the score of VAS(lumbar). Conclusions: PTED showed great effect on treating patients with lumbar disc herniation. And the main scale score such as VAS(leg). ODI and JOA showed that there is a statistically significant difference between the three subpopulations treated by PTED. Patients with SLR negative may get greater benefit from PTED.
