Does the presence of radiculopathy affect sleep quality and lower extremity functionality in neuropathic low back pain?

Sleep disturbance in chronic neuropathic low back pain is a well-known condition. In this study, we aimed to investigate the effect of lumbar radiculopathy on sleep quality and lower extremity functionality in the presence of neuropathic low back pain. A total of 79 patients diagnosed with disk herniation, needle electromyography, and neuropathic pain were included in the study. Visual Analog Scale, Pittsburg Sleep Quality Index, and Lower Extremity Functionality Scale were applied to the patients. Of the 79 patients who participated in the study, 34 (43%) were females and 45 (57%) were males. No significant difference was found between the group with and without radiculopathy in terms of sleep quality and lower extremity functionality (p=0.245 and p=0.092, respectively). In our study, a negative correlation was found between night pain and the presence of radiculopathy (p=0.006). The number of lumbar herniated disk levels was higher in the group without radiculopathy and was statistically significant (p=0.023). We found that the presence of radiculopathy did not affect sleep quality and lower extremity functionality in disk herniation patients with neuropathic pain. Although it was not statistically significant in our study, we think that the degree of herniation may affect sleep and lower extremity functionality rather than the number of disk herniation levels with the available data. The fact that neuropathic pain is not limited to disk herniation and radiculopathy, and that neuropathic pain is intertwined with clinical conditions such as anxiety, sleep disorders, and depression are among the conditions that make the studies difficult.

Comparison of Clinical Effectiveness between the Management of Cervical and Lumbar Disc Herniation with Percutaneous Laser Disc Decompression Followed by Interlaminar Cervical Epidural and Lumbar Transforaminal Epidural Steroid Injection Respectively

Background: Different treatments for discogenic axial back/neck pain or radicular pain to limbs are there from conservative therapies and minimally invasive therapies to open spine surgeries with lots of controversial outcomes. Percutaneous laser disc decompression (PLDD) is one of the minimally invasive therapies which is done under local anesthesia and has been successfully performed in many selected patients for their lumbar and cervical disc herniation problems. In PLDD, a part of the nucleus pulposus is vaporized with the help of laser energy to reduce the intradiscal pressure of the diseased discs causing nerve compression. In this case series after a 1-year follow-up, the clinical effectiveness of PLDD with epidural steroid injection is assessed in selected lumbar and cervical disc herniation cases. Materials and Methods: Ninety-six patients underwent the PLDD procedure at the cervical and lumbar disc with epidural steroid injections for their disc herniation causing radicular pain in the upper and lower limbs, respectively. The patients were followed at 8 weeks, 3 months, 6 months, and 1 year. The main outcome measures were done through the visual analog scores (VASs) and the Oswestry Disability Index (ODI) for upper and lower limb pain. Results: The primary outcome showed that there is a significant clinically relevant difference between the two groups at a 1-year follow-up. VAS and mean disability score based on the ODI were significantly lower in cervical disc herniation patients. The reoperation rate in the cervical group is also much less than the lumbar group. Conclusion: Like all other surgical modalities for disc herniation, PLDD has its own advantages and disadvantages. However, compared to lumbar disc herniation, it may give better results in cervical disc herniation. In selected cases, combined PLDD with epidural steroid injection can be chosen as a “first-choice-minimally-invasive-treatment,” when standard conservative therapies do not give satisfactory outcome.

Observation on effect of differentiated teaching based on LEARNS model in patients with lumbar disc herniation

To explore the effectiveness of differentiated instruction based on The LEARNS mode in the treatment of lumbar disc herniation. 86 patients in total with lumbar disc herniation who were hospitalized in the orthopedics Department of Nanjing Integrated Traditional Chinese and Western Medicine Hospital from March 2022 to February 2023 were randomly divided into the observation group and the control group with 43 cases in each one. Patients in the control group were routinely taught with conventional syndrome differentiation, while those in the observation group adopted patient-centered LEARNS model to carry out syndrome differentiation teaching. The exercise of self-care agency (ESCA), short form health survery (SF-36) and satisfaction levels before intervention and 90 days after intervention were compared between the two groups. There were no significant differences found in ESCA, SF-36 and satisfaction before intervention between the two groups (p>0.05). Ninety days after intervention, the ESCA, SF-36 and satisfaction in the observation group were significantly higher than those in the control group (p<0.05). The differentiated teaching based on LEARNS model has good application effect on lumbar disc herniation patients, and it is an effective alternative method of traditional Chinese medicine nursing health education in clinical practice.

Paraoxonase 1 Activity and Phenotype Distribution in Lumbar Disc Herniation Patients.

To compare the Paraoxonase 1 (PON1) activity and phenotype distribution between lumbar disc herniation (LDH) patients and healthy individuals. This research included 40 LDH patients and 42 healthy individuals. Spectrophotometric assays were performed to determine the serum PON1 and arylesterase activities. The PON1 ratio, which represents the salt-stimulated PON/ arylesterase level, demonstrated a trimodal distribution. This ratio was applied to identify the different phenotypes; QQ, QR, and RR of each subject. The LDH patients had lower PON1 activity than the healthy individuals (p < 0.05). LDH patients had a statistically significant QQ phenotype compared to the healthy subjects (p < 0.05). LDH patients had statistically lower PON1 activity, suggesting that the low PON1 activity and PON1 QQ phenotype may be a risk factor for LDH occurrence.

Physiotherapy Interventions versus Surgical Interventions for Patients with Prolapsed Lumbar Intervertebral Disc (PLID): A Critical Review

The most common predisposing factor for low back pain is a prolapsed lumber intervertebral disc. It is the most prevalent symptom in the modern population, albeit it was formerly the ancient curse of society, and it affects 80% of the population at some time in their lives. The goal of this study was to assess the efficacy of physiotherapy versus surgery for patients with prolapsed intervertebral disc. A thorough search of Medline, Embase, CINAHL, CENTRAL, and PEDro was done. Randomized control trial and prospective cohort study relevant to physiotherapy versus surgery, physiotherapy management alone, surgery among the lumbar disc herniation patients were included. Studies that were written in English and came out between 2006 and 2018 were enlisted using inclusion criteria. For screening, identified similar types of articles, avoid duplicate articles, and finally compare and contrast 5 articles. In the short-term, according to the majority of the articles, surgery was more beneficial than conservative treatment. However, there was no discernible difference between physiotherapy and surgery after a long period of observation, and the re-operation rate after surgery was 3%–20% within the first 1–2 years. Physiotherapy intervention had no adverse effects, whereas surgery had some adverse effects. In all circumstances, physiotherapy intervention is more effective than surgery. Physiotherapy interventions should be prescribed in a structured way.

Effect of caudal epidural adhesiolysis plus steroid injections on pain and daily activities among chronic lumbar disc herniation patients; an observational study

Background &amp; Objective: The management of lumbar disc herniation (LDH) remains a big challenge as it may involve the surrounding tissues, and attract neovascularization facilitated macrophage aggregates. Epidural triamcinolone might have a half-life action ranging from 10 to 31 days, whereas 80 mg methylprednisolone might improve the pain up to 1 week. The higher doses of steroids will lead to adrenal cortex suppression and osteopenia. We evaluated the effect of treatment with 1500 international unit (IU) hyaluronidase followed by 20 mg triamcinolone at 2 weeks, and 3 and 6 months follow-up.&#x0D; Methodology: We enrolled seven males (38.9%) and 11 females (61.1%) with mean age 44 ± 23 y in the study. Eight (44.44%) subjects were younger than 51 y old, whereas the 10 (55.56%) subjects were ≥ 51 y old. Twelve (66.7%) subjects had had a bulged disc, and 6 (33.3%) subjects had disc protrusion. We injected 1500 international unit (IU) hyaluronidase followed by 20 mg triamcinolone at the site of disc lesion. Pain scores were measured with NRS scale and Oswestry Disability Index (ODI) scores at 2 weeks, and 3- and 6-months follow-up.&#x0D; Results: The NRS score improved at 2 weeks, 40% to 71.43%, at 3 months 60% to 100%, and 6 months 80% to 100%. And the Oswestry Disability Index (ODI) score was improved at 2 weeks from 23.5% to 68.18%), at 3 months from 39.13% to 100%, and at 6 months 82.35% to 100%. A significant association was observed between age older than 50 y old and ODI scores at 2 weeks followed up.&#x0D; Conclusions: The intra-epidural 1500 IU hyaluronidase before triamcinolone brings better results even though using a lower dose of triamcinolone. This approach showed the lower-cost better pain scores as compared to the routine use of heavy doses of triamcinolone for managing bulged and protruding LDH.

Cirrhosis and hernia repair in a cohort of 6352 patients in a tertiary hospital: Risk assessment and survival analysis.

The prevalence of hernias in patient with cirrhosis can reach up to 40%. The pathophysiology of cirrhosis is closely linked to that of the umbilical hernia, but other types are also common in this population. The aim of this study is to evaluate factors that influence in the prognosis after hernia repair in patients with cirrhosis. A historical cohort of 6419 patients submitted to hernia repair was gathered. Clinical, epidemiological data and hernia characteristics were obtained. For patient with cirrhosis, data from exams, surgery and follow-up outcomes were also analyzed. Survival curves were constructed to assess the impact of clinical and surgical variables on survival. 342 of the 6352 herniated patients were cirrhotic. Patient with cirrhosis had a higher prevalence of umbilical hernia (67.5% × 24.2%, P < .001) and a lower prevalence of epigastric (1.8% × 9.0%, P < .001) and lumbar (0% × 0.18%, P = .022). There were no significant differences in relation to inguinal hernia (P = .609). Ascites was present in 70.1% of patient with cirrhosis and its prevalence was different in relation to the type of hernia (P < .001). The survival curve showed higher mortality for emergency surgery, MELD > 14 and ascites (HR 12.6 [3.79-41.65], 4.5 [2.00-10.34], and 6.1 [1.15-20.70], respectively, P < .05). Hernia correction surgery in patient with cirrhosis has a high mortality, especially when performed under urgent conditions associated with more severe clinical conditions of patients, such as the presence of ascites and elevated MELD.

Cervical microendoscopic laminoplasty-induced clinical resolution of disc herniation in patients with single- to three-level myelopathy

This study aimed to explore the effects on resorption of cervical disc herniation (CDH) and clinical outcomes of surgery. Cervical microendoscopic laminoplasty (CMEL), which is commonly preferable to anterior corpectomy and fusion, was applied to patients with 1- to 3-level degenerative cervical myelopathy (DCM). DCM patients with 1–3 levels DCM underwent either conservation treatment or CMEL. In conservation-treated patients (53 cases), CDH volume remained unchanged with no improvement in JOA and VAS scores. Conversely, 63 patients with 1–3 levels DCM were prospectively enrolled and exhibited a profound decrease in CDH volume: 89.1% of CDHs (123/138) regressed over 10%, 64.5% of CDHs (89/138) regressed over 25%, while 27.5% and 6.5% of CDHs (38/138 and 9/138) largely regressed over 50% and 75%, respectively. Meanwhile, the JOA and VAS scores were improved in different ways. Intriguingly, CDH volume changes correlated significantly with elevations in JOA scores, indicating an association of clinical CDH resolution with neurological recovery. We showed that CMEL induced clinically related diminishment of CDH and alleviation of clinical symptoms in patients with 1- to 3-level myelopathy and that it could help avoid anterior dissection of the disc to some extent.

Morphometric similarity networks discriminate patients with lumbar disc herniation from healthy controls and predict pain intensity.

We used a recently advanced technique, morphometric similarity (MS), in a large sample of lumbar disc herniation patients with chronic pain (LDH-CP) to examine morphometric features derived from multimodal MRI data. To do so, we evenly allocated 136 LDH-CPs to exploratory and validation groups with matched healthy controls (HC), randomly chosen from the pool of 157HCs. We developed three MS-based models to discriminate LDH-CPs from HCs and to predict the pain intensity of LDH-CPs. In addition, we created analogous models using resting state functional connectivity (FC) to perform the above discrimination and prediction of pain, in addition to comparing the performance of FC- and MS-based models and investigating if an ensemble model, combining morphometric features and resting-state signals, could improve performance. We conclude that 1) MS-based models were able to discriminate LDH-CPs from HCs and the MS networks (MSN) model performed best; 2) MSN was able to predict the pain intensity of LDH-CPs; 3) FC networks constructed were able to discriminate LDH-CPs from HCs, but they could not predict pain intensity; and 4) the ensemble model neither improved discrimination nor pain prediction performance. Generally, MSN is sensitive enough to uncover brain morphology alterations associated with chronic pain and provides novel insights regarding the neuropathology of chronic pain.

A Genetic Variant of the ROBO3 Gene is Associated With Adolescent Idiopathic Scoliosis in the Chinese Population.

A case-control association study. This study aimed to reveal whether mutations within roundabout receptor 3 ( ROBO3 ) gene were related to adolescent idiopathic scoliosis (AIS) in Chinese Han population and to investigate the functional role of ROBO3 in the pathogenesis and progression of AIS. ROBO3 is essential for the regulation of hindbrain axonal cell migration and midline crossing. Studies have demonstrated that ROBO3 homozygous mutations are associated with horizontal gaze palsy with progressive scoliosis. However, whether and how ROBO3 contributed to the development of scoliosis remains unclear. Whole exome sequencing was performed in 135 AIS patients and 267 healthy controls to evaluate the differences of single nucleotide polymorphism variants within ROBO3 . Then the identified variant of ROBO3 was genotyped in another cohort included 1140 AIS patients and 1580 controls. Moreover, paraspinal muscles were collected from 39 AIS patients and 45 lumbar disk herniation patients for the measurement of ROBO3 mRNA expression. The χ 2 test, Fisher exact test or the Student t test were used to compare intergroup data. Pearson correlation was used to determine the association between ROBO3 expression and clinical phenotypes. A significant association was identified between the gene variant (rs74787566) of ROBO3 and the development of AIS through exome sequencing. The genotyping cohort demonstrated a higher frequency of allele A in AIS patients compared to controls (7.89% vs . 4.30%, P <0.001, odds ratio=1.87). In addition, the expression of ROBO3 in paraspinal muscles was inversely correlated with the Cobb angle ( P =0.043, r2 =0.1059). A significant association was identified between the gene variant (rs74787566) of ROBO3 and the development of AIS. The reduced expression of ROBO3 could result in the progression of curve magnitude in patients with AIS. Further studies are needed to verify the functional role of ROBO3 in the development of AIS. Level III.

Is lumbosacral transitional vertebra associated with lumbar disc herniation in patients with low back pain?

To evaluate lumbosacral transitional vertebrae (LSTV) frequency in patients with low back pain and lumbar disc herniation (LDH) and to analyze correlations between LSTV presence and intervertebral disc degeneration. This retrospective study included patients with low back pain applying between January 2021 and August 2021. Inclusion criteria were age of 18-65, presence of a standing lumbosacral Xray and a lumbar MRI taken within 2weeks of the indexed symptoms. Patients with a history of spondylolisthesis, spondylodiscitis, scoliosis and vertebral neoplasia were excluded. A total of 1821 patients met the inclusion criteria. Radiographs and MRIs were evaluated by 2 radiologists. Of all patients, 61.4% were female and the mean age was 43.2 ± 12.2. LDH was detected in 57.7% of patients while a LSTV was present in 43.3%. Sacralization and LSTV were significantly different between the patients with and without an LDH. Patients with LSTV had a higher incidence of a LDH affecting 3 or more intervertebral disc levels (p < 0.001). There was a significant difference in-between LSTV and non-LSTV groups regarding the M1 and M2 intervertebral disc degeneration levels. A LDH is more common in the presence of a LSTV. Female sex is highly correlated with herniation. Three or more intervertebral disc levels are affected in the presence of an LSTV. Significantly higher degeneration incurs at the M1 and M2 intervertebral levels. Sacralization is a risk factors for a lumbar disc herniation.

Analysis of Chronic Low Back Pain Caused by Lumbar Microinstability After Percutaneous Endoscopic Transforaminal Discectomy: A Retrospective Study.

ObjectiveChronic low back pain (CLBP) after percutaneous endoscopic transforaminal discectomy (PTED) surgery may be caused by preoperative lumbar microinstability (MI). However, there is a paucity of research on the relationship between lumbar microinstability and chronic low back pain. The purpose of this article is to assess the preoperative radiographic characteristics of patients and evaluate the effects of lumbar microinstability on patient-reported outcomes among single-level lumbar disc herniation (LDH) patients who underwent PTED.MethodsThis study retrospectively reviewed the radiographic characteristics of a consecutive series of 127 patients with low back pain and leg pain caused by single-level LDH underwent PTED from August 2018 to March 2021. They were divided into three groups according to the radiographic parameters: the stable group (Group S), the dysfunctional group (Group D), and the microinstability group (Group M). The visual analogue scale (VAS) scores for leg and low back pain and Oswestry Disability Index (ODI) were evaluated preoperatively and postoperatively. Logistic regression analysis was used to identify independent risk factors for CLBP.ResultsCompared with Group D and Group S, Group M had the highest ODI scores (P < 0.01) and VAS scores (low back pain) (P < 0.01) after 1 year, while there were no significant differences in the VAS scores for leg pain at different time points after surgery (P > 0.05). In addition, the logistic regression analysis results regarding CLBP revealed that muscle fatty degeneration on MRI (95% CI, 1.20–8.51, P = 0.02), and facet tropism (95% CI, 1.39 −11.37, P = 0.01) may be independent risk factors.ConclusionPatients with lumbar microinstability may have CLBP after PTED, so patients with lumbar microinstability may need to take internal fixation surgery to solve their symptoms.

Gait asymmetry of lower extremities reduced immediately after minimally invasive surgery among patients with lumbar disc herniation

BackgroundLumbar disc herniation patients with increased pain exhibit greater gait asymmetry in stance time, swing time and single support time. Percutaneous endoscopic lumbar discectomy, as a minimally invasive surgical procedure has been used to treat patients with lumbar disc herniation. The objective of this study was to evaluate the immediate impact of the percutaneous endoscopic lumbar discectomy on gait asymmetry in spatiotemporal and kinetic parameters among lumbar disc herniation patients. MethodsMarker trajectories and ground reaction forces were measured during walking among 67 lumbar disc herniation patients and 15 healthy controls. Spatiotemporal gait parameters were analyzed via Visual3D. Muscle force and joint contact force were calculated with OpenSim. Gait asymmetry of those parameters were assessed with asymmetry index. FindingsAfter surgery, gait asymmetry in gait cycle time, step length, peak biceps femoris long head, tensor fasciae latae and rectus femoris muscle forces, and peak hip and knee joint contact forces reduced immediately. Postoperatively, increased gait cycle time and decreased step length were found in the affected side. Moreover, decreased peak biceps femoris long head, tensor fasciae latae and rectus femoris muscle forces, and peak hip joint contact force were observed in the contralateral side. InterpretationThese results suggested compensation strategy that biceps femoris long head, tensor fasciae latae and rectus femoris in the contralateral side were mainly used to compensate the affected side preoperatively in lumbar disc herniation patients, with less compensation between lower limbs after surgery, which may provide an insight into postoperative rehabilitation.

Clinical Efficacy Analysis of Fast Rehabilitation Nursing on Pain Mitigation after Lumbar Discectomy and Bone Graft Fusion and Internal Fixation.

Objective To investigate clinical efficacy analysis of fast rehabilitation nursing on pain mitigation after lumbar discectomy and bone graft fusion and internal fixation. Methods A total of 60 patients with lumbar disc herniation who underwent lumbar discectomy and bone graft fusion and internal fixation in our hospital from January 2021 to December 2021 were randomized either into routine group (n = 30) or rehabilitation group (n = 30) via the random number table method. The patients in the routine group were intervened with the routine postoperative nursing mode, and the patients in the rehabilitation group were intervened with the fast rehabilitation nursing mode on the basis of the nursing of the patients in the routine group. The rehabilitation effect, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores, postoperative pain improvement, and nursing satisfaction were compared between the two groups. Results The postoperative rehabilitation effect of the rehabilitation group was significantly better than that of the routine group (P < 0.05). The fast rehabilitation nursing resulted in a notably lower postoperative SAS and SDS scores versus the routine nursing (P < 0.001). The postoperative pain was significantly mitigated in the rehabilitation group when compared with the routine group (P < 0.001). The fast rehabilitation nursing implemented in the rehabilitation group led to a remarkably higher nursing satisfaction of the patients (P < 0.001). Conclusion The fast rehabilitation nursing mode intervention for lumbar disc herniation patients undergoing lumbar discectomy and bone graft fusion and internal fixation is a promising approach to improve the postoperative rehabilitation, mitigate postoperative pain, and relieve anxiety, depression, and other negative emotions, with higher clinical nursing satisfaction.

Analysis of the resilience level and associated factors among patients with lumbar disc herniation

This study aims to determine the resilience level and its influence on anxiety among Chinese lumbar disc herniation (LDH) patients, and to determine the critical psychological and non-psychological predictors of resilience among LDH patients. Twenty hundred and fifty LDH patients from a tertiary hospital in Jinzhou, China were included in this survey to answer the Resilience Scale-14 (RS-14), Zung Self-Rating Anxiety Scale (SAS), Herth Hope Index (HHI), Revised Life Orientation Test (LOT-R), Multidimensional Scale of Perceived Social Support (MSPSS), Perceived Stress Scale-10 (PSS-10). The mean resilience level of LDH patients was 61.96 ± 12.37. Resilience was negatively correlated with anxiety (χ2 = 32.603, p < 0.001), accompanied by a significant linear trend (χ2 = 28.567, p < 0.001). Hope, stress, social support, and medical payment type accounted for 48.7% resilience variance. This study reveals that Chinese LDH patients had low resilience level, and that lower level of resilience was closely associated with higher anxiety level. The predictors for resilience among LDH patients include hope, stress, social support, as well as medical payment types. These findings provide local government and related health-care professionals with a basis for development of targeted mental health management of Chinese LDH patients, and will also help to devise appropriate health intervention strategies for promoting the mental health status of LDH patients.

Medical Data Analysis of Lumbar Disc Herniation Patients after Traditional Chinese Medicine Rehabilitation Intervention Lumbar Function Recovery

In order to study the efficacy of TCM rehabilitation for lumbar disc herniation, it is suggested to compare the effects of hot compress, ordinary sandbag, or hot compress with traditional Chinese medicine. A total of 79 patients with Qi stagnation and blood stasis syndrome in a traditional Chinese medicine hospital who met the diagnostic criteria of LDH and the syndrome classification in the diagnostic efficacy criteria of traditional Chinese medicine were selected. The subjects were randomly divided into groups A, B, and C: group A (26 cases) was the sandbag hot compress dry pregroup and received the simple sandbag hot compress scheme; group B (26 cases) was a simple traditional Chinese medicine hot compress intervention group, which received traditional Chinese medicine hot compress scheme; group C (27 cases) was the intervention group of traditional Chinese medicine sandbag combined with hot compress and received the scheme of traditional Chinese medicine sandbag combined with hot compress. In addition to the different hot compress media used, other aspects remained the same among the three groups. The treatment time of each hot compress was 40 min, twice a day for 2 weeks. A total of 14 cases fell out during the intervention process, and 65 subjects completed the intervention process. The experiment showed that there was no significant difference among the three groups (P > 0.05). The test results were confirmed.

A retrospective comparative study of local anesthesia only and local anesthesia with sedation for percutaneous endoscopic lumbar discectomy.

It is still an unsolved problem to achieve both immediate intraoperative feedback and satisfactory surgical experience in percutaneous endoscopic lumbar discectomy under local anesthesia for lumbar disk herniation (LDH) patients. Herein, we compared the analgesic and sedative effects of local anesthesia alone and local anesthesia with conscious sedation in LDH patients during percutaneous endoscopic lumbar discectomy. Ninety-two LDH patients were enrolled and divided into the following groups: control group (Con Group), dexmedetomidine group (Dex Group), oxycodone group (Oxy Group), and dexmedetomidine + oxycodone group (Dex + Oxy Group). Various signs, including mean arterial pressure (MAP), heart rate (HR), pulse oximeter oxygen saturation (SpO2) and Ramsay score, were compared before anesthesia (T1), working cannula establishment (T2), nucleus pulposus removal (T3), and immediately postoperation (T4). Clinical outcomes, including VAS score, operation time, hospitalization period, Macnab criteria, and SF-36 score, were also evaluated. The Dex + Oxy Group showed the most stable MAP and HR at T2 and T3 in all groups. The clinical outcomes, such as VAS, hospitalization period, Macnab criteria, and SF-36 score, have no significant differences among groups (p > 0.05). Local anesthesia combined with conscious sedation is a safe and effective method to improve the surgical experience and achieve satisfying clinical outcomes for LDH patients during percutaneous endoscopic lumbar discectomy.

Increased local miR-21 expressions are linked with clinical severity in lumbar disc herniation patients with sciatic pain.

The miR-21 has been implicated in the process of neuroinflammation as well as neuropathic pain. To explore the relationship between the plasma and local expression of miR-21 with disease severity of lumbar disc herniation (LDH) patients with sciatic pain. Ninety-two LDH patients with sciatic pain and 25 scoliosis patients as painless controls were enrolled in the current study. Samples from nucleus pulposus (NP), annulus fibrosus (AF) and soft tissues around nerve root (STANR) were obtained. The plasma and local expressions of miR-21 were detected with quantitative reverse transcription polymerase chain reaction (qRT-PCR). The visual analogue scale (VAS) for lumbar pain and leg pain, and Japanese Orthopedic Association (JOA) score were selected to evaluate the clinical severity. The degree of disc compression on nerve was evaluated using the Pfirrmann grade based on the magnetic resonance imaging (MRI) findings. For the convenience of analysis, LDH patients with sciatic pain were classified into a severe pain (SP) group (VAS ≥ 6) and a mild-moderate pain (MP) group (VAS < 6). Receiver operating characteristic (ROC) curve analysis was performed to detect the potential diagnostic power of miR-21 with regard to the Pfirrmann grade. There were no significant differences in serum miR-21 expressions among SP LDH patients, MP LDH patients and scoliosis painless controls. Local expressions of miR-21 in STANR, AF and NP were all drastically upregulated in the SP group in comparison with the MP group and scoliosis painless group. Local NP and STANR miR-21 expressions were positively associated with the Pfirrmann grade. Local miR-21 expressions in STANR and AF were positively associated with VAS score and negatively related to JOA score. The ROC curve analysis indicated that both STANR and AF miR-21 expressions may serve as significant diagnostic factors for the Pfirrmann grade. Increased local miR-21 expressions are linked with clinical severity of LDH in patients with sciatic pain.

Clinical outcomes and satisfaction in patients after lumbar microdiscectomy

Introduction: Lumbar disc herniation is a common cause of low back and radicular pain. Microdiscectomy is the recommended surgical technique for herniated lumbar discs at the moment. It has great success rates and little postoperative morbidity. We aimed to assess the clinical result and patient satisfaction of micro-discectomy in lumbar disc herniation patients. Methodology: This is a prospective observational hospital-based research of 26 patients who had micro-discectomy at the Regional Clinical Center of Neurosurgery and Neurology in Uzhhorod, Ukraine, during August and September 2021. The research excluded patients with recurrent prolapsed intervertebral discs, multiple level herniated discs, and disc surgery requiring stability. During surgery, the kind of prolapsed intervertebral disc, its level, and the duration of the procedure were recorded. Additionally, we recorded the duration of the patient's hospital stay and any complications. The visual analogue scale (VAS), the Oswestry Disability Index (ODI), and the MacNab score questionnaires were used to measure pain, disability, and patient satisfaction, respectively. Result: All procedures were performed on a single level using micro-discectomy. The mean age of the study population was 45.69 years. Micro-discectomy surgeries were performed in less than an hour in 69.2% of cases. The most often seen lumbar prolapsed intervertebral disc occurred at the L4-L5 level (57.7%). The most often seen kinds of prolapse were disc extrusion (30.8%) and disc sequestration (26.9%). The mean length of stay in the hospital was 3.96 days. After surgery, 57.7% of patients received an excellent rating on the Macnab's scale. There was a statistically significant difference between pre- and postoperative VAS and ODI scores (p&lt;0.05). Conclusion: Overall 65.4% of patients had no postoperative complications. In these instances, a proper surgical technique might help avoid problems. Our findings demand additional investigation with bigger sample sizes and longer follow-up periods.
