Structure And Morphology

It is understood that the effect of exercise rehabilitation drugs in patients with lumbar disc herniation is poor. Some studies have shown that bismuth tungstate nanomaterials with certain morphology can treat the exercise rehabilitation of patients with lumbar disc herniation. In order to help patients with lumbar disc herniation to a certain extent, in this paper, bismuth tungstate nanomaterials with different structures and morphologies were prepared by hydrothermal method, and viscous tungsten nanomaterials with different structures and morphologies were prepared by adjusting the pH value of the solution and the concentration of CTAB. In this paper, the structure and morphology of tungsten samples with different structure and morphology were characterized by CTAB X-ray (XRD) deflection and FESEM. It was found that the morphology of the samples changed after adding 0.02 mol/L surfactant CTAB in the reaction system, and when the concentration of CTAB was 0.04 mol/L, the nanotubes were stacked together under the action of surfactant. When the concentration of CTAB increased to 0.06 mol/L, the self-assembled nanocomposites tended to be petal like.

Lower Lumbar

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.

Abstract Eighty patients with operatively proven lumbar disc herniation or lumbar spondylosis were preoperatively evaluated with metrizamide myelography followed by metrizamide-enhanced computed tomography (CT). The x-ray films were reviewed without knowledge of the operative findings, and the patients were subdivided into those with disc extrusions, spondylosis, or recurrent abnormalities. For the group as a whole, CT was correct in 82% and myelography was correct in 77%. Both CT and myelography together were accurate in 91%, a significant improvement (P&lt;0.02). The authors conclude that, if both studies are performed, the percentage of cases correctly diagnosed is increased. Therefore, both metrizamide myelography and metrizamide-enhanced CT should be obtained in selected cases. A review of the literature is included.

Common Procedure

Summary Lumbar disc herniation (LDH) is the most common pathology in young people, as well as people of active age. Despite sophisticated and new minimally invasive surgical techniques and approaches, reoperations for recurrent lumbar disc herniation (rLDH) could not be avoided. LDH recurrence rates, reported in different studies, range from 5 to 25%. The purpose of this study was to estimate the recurrence rates of LDH after standard discectomy (SD) and microdiscectomy (MD), and compare them to those reported in the literature. Retrospectively, operative reports for the period 2012-2017 were reviewed on LDH surgeries performed at the Neurosurgery Clinic of Dr Georgi Stranski University Hospital in Pleven. Five hundred eighty-nine single-level lumbar discectomies were performed by one neurosurgeon. The diagnoses of recurrent disc herniation were based on the development of new symptoms and magnetic resonance/computed tomography (MRI/CT) images showing compatible lesions in the same lumbar level as the primary lumbar discectomies. The recurrence rate was determined by using chi-square tests and directional measures. SD was the most common procedure (498 patients) followed by MD (91 patients). The cumulative reoperation rate for rLDH was 7.5%. From a total number of reoperations, 26 were males (59.1%) and 18 were females (40.9%). Reoperation rates were 7.6% and 6.6% after SD and MD respectively. The recurrence rate was not significantly higher for SD. Our recurrence rate was 7.5%, which makes it comparable with the rates of 5-25% reported in the literature.

Introduction: Surgical wound infection in developing coutries is about 3%. Antibiotics prophylaxis may help to reduce the surgical site infection. The objective of this study was to evaluate the efficacy of antibiotics prophylaxis in patients with lumbar disc herniation who were treated with lumbar discectomy at Hue University hospital. Materials and Methods: A prospective study was conducted at Hue University hospital from March 2015 to May 2018 on 54 patients with lumbar disc herniation who were used antibiotics prophylaxis when undergoing discectomy. Results: The infection rate in our study was 0%. Antibiotics prophylaxis reduced the length of hospitalization as well as the medical cost. Conclusion: Antibiotics prophylaxis was effective in preventing surgical site infection despite the fact that the condition of operating rooms did not meet the standard rules. Key words: prophylaxis antibiotics, lumbar disc herniation
