Demographic data are summarized in Table 1. Tissue inhibitors of matrix metallo-proteinase (TIMPs) are proteinase inhibitors that suppress extracellular matrix degradation. A post hoc analysis was completed to reveal a power of (1-ß) = 0.87. https://doi.org/10.1371/journal.pone.0128321.g002. Since axial loading causes disc height loss [23], this study probed any possible correlations between disc height and the ligamentum flavum thickness. Symptoms Thickness differences between low back pain and asymptomatic subjects were then examined by level. No, Is the Subject Area "Measurement" applicable to this article? Most of these studies lack a direct comparison between patients with lumbar spinal stenosis and a control group. „gelbes Band“) ist ein jeweils zwischen zwei Wirbeln gelegenes, die Wirbelsäule stabilisierendes Band.. Lateral recess stenosis, which is a frequent finding in older patients with lumbar radiculopathy, may have an earlier basis with lateral thickening of the ligamentum flavum and low back pain. I had surgery on my lower back 1 year ago, my MRI Report is saying AT L2-3, there is redemonstration of mild ligamentum flavum hypertrophy and facet arthropathy. As suggested previously,1,3,4) the mechanism of LFH may depend on the following characteristics. No, Is the Subject Area "Imaging techniques" applicable to this article? Sixty-three individuals were part of this IRB-approved study: twenty-seven with chronic low back pain, and thirty-six as asymptomatic. However, no correlation was found between the disc height and the ligamentum flavum thickness in our series. Lohr M, Hampl JA, Lee JY, Ernestus RI, Deckert M, Stenzel W (2011) Hypertrophy of the lumbar ligamentum flavum is associated with inflammation-related TGF-beta expression. The finding that an increase in lateral ligamentum flavum thickness was more significant than medial ligamentum flavum thickness is also notable. Here are the symptoms and causes of ligamentum flavum hypertrophy … Large uniform dorsal disc bulge at L4/5 which coupled with facet joint and ligamentum flavum hypertrophy results in a mild degree of focal canal stenosis here. The AIS causes – aging, injury and sprain- all comes under one Dosha only and that is- Vata Dosha only. Purpose To examine ligamentum flavum thickness using magnetic resonance (MR) images to evaluate its association with low back pain symptoms, age, gender, lumbar level, and disc characteristics. Study L05090801 is a larger study that probed the relationships between disc and facet degeneration and in vivo lumbar kinematics, which involved lumbar spine imaging (both CT and MR) of subjects in various torso positions (supine and axial rotation, as shown elsewhere[14, 17–19]). Yes This site uses cookies for best performance. Ligament inflammation can be simply yet another demonized structural issue which is basically normal in the spines of adults and mistakenly blamed for enacting back or neck pain. The selection criteria for the low back pain group excluded subjects with severe disc collapse and stenosis. For the medial measurement, the youngest group was significantly smaller than the two older groups (40s and 50s, p < 0.03), whereas the lateral measurement showed more differences, as follows: 20s<30s, 20s<40s, 20s<50s and 30s <50s, p < 0.0185. The authors found the ligamentum flavum to be the primary cause of canal encroachment, with bulging of the ligament leading to 50 to 85% of the reduction in canal area [22]. In this condition, the ligament attaching vertebrae together is stretched and bended and do not come to its original position even after relaxing. Medial and lateral ligamentum flavum measurements were related to disc height, and disc grade.

Recent data indicate that miR-155 plays a crucial role in the pathogenesis of different fibrotic diseases. Alternative Medicine, Herniated Disc Depression Magnetic resonance imaging was used to provide a cross-sectional view of the lumbar spinal canal from L1/2 to L5/S1. This yellow ligament attaches to the inside of the vertebrae, rearward of the central spinal canal. Performed the experiments: RT JJM JYBL AAEO. flavum, along with hypertrophy of the ligamentum flavum, are associated with lumbar spinal stenosis. Ligamentum flavum thickness was measured at two different locations in the present study. It … Statistical significance was achieved at fewer levels than with the medial ligamentum flavum measure, with L1 thickness being significantly less than L3, L4, and L5; and L2 significantly less than L4. Asterisks denote significant differences with * p < 0.05. I have seen a few cases in which the ligamentum flavum has become so inflamed or lax that it has actually captured and compressed a nerve root. Comparison between asymptomatic and chronic low back pain subjects segregated by spinal level. The assigned DOI is as follows: http://dx.doi.org/10.6084/m9.figshare.1301159. Patient has drastic osteoarthritic change which has closed off much of the anterior central canal and is finished off by the ligamentum hypertrophy. Exclusion criteria for the asymptomatic group were ongoing low back pain, previous spinal surgery, history of low back pain, age over 60 years, obesity, or claustrophobia or other contraindication to MR or CT imaging. Das Ligamentum flavum (lat. Previous studies showed that the ligamentum flavum thickness at the segments L 2/3 , L 3/4 , L 4/5 and L 5 /S 1 was positively correlated with age. Inclusion criteria for the low back pain group were recurrent pain in the low back with at least two episodes each lasting at least 6 weeks and brought on by modest physical exertion. R01-AT006692-01A1. Competing interests: The authors have declared that no competing interests exist. Paired t-tests were used to compare thickness on left and right sides. s? Spinal Decompression Everyone accepts the role of ligamentum flavum hypertrophy in the development of symptomatic disease. It is thought to be mostly from fibrosis caused by the accumulation of mechanical stress with the ageing process, especially along the dorsal aspect of the ligamentum flavum. Yes Canal narrowing, in part, results from hypertrophy of the ligamentum flavum. All patients underwent MR imaging and computed tomography (CT) of the lumbar spine. Minor back injury or mechanical stress in the lumbar spine, such as that caused by housework or exercise, might cause a tear in the degenerative ligamentum flavum. Arrows indicate lateral thickness (LAT) and medial (MED) thickness. One of the imaging modalities included in the study was MRI to evaluate the quality of the subjects’ intervertebral discs. Sleep Position for Herniated Disc. This study aimed to test the hypothesis that miR-155 exerts effects on LF thickness by regulating collagen expression. Unpaired t-tests were used to compare measurements between genders and asymptomatic/symptomatic subjects. Degenerative Disc Disease Howard S. An, Hansson et al. This diagnosis is a common finding on herniated disc MRI results and is often a puzzle for patients who do not understand the terms on the report. These ligaments connects the vertebral column together. Know the facts about the condition before seeking any drastic treatment option to minimize your chances of falling victim to failed spinal surgery syndrome, since invasive procedures are the usual therapy protocol. While traditionally the focus of discussion has been on the bulging of the disc leading to compression of the cauda equina, there is growing evidence that identifies ligamentum flavum buckling and hypertrophy as the key pathologic feature of spinal stenosis. Joe Y. Measurement lines were perpendicular to ligamentum flavum length (Fig 1). Given that the parent study for this research was not designed to obtain normative data, our results might be limited due to relatively small subject population. Dr. Edward Hellman answered. Conceived and designed the experiments: HSA NI GBJA. With the medial measurement, thickness was smallest at L1 and L5, and increased caudally from L2 to L4; statistical significance was found between all levels except L1 and L5 (p = 0.13). Many studies suggest that the ligamentum flavum is a key factor in the pathogenesis of lumbar spinal stenosis [1–6]. e0128321. Typically this occurs under any of the following scenarios: Patient demonstrates a large central or paramedial herniated disc which is creating a stenosis condition on the frontal and side areas of the central canal. The MR images at the mid-disc level were captured and enlarged 800% using a bilinear interpolation size conversion algorithm that allowed for enhanced image quality. P01-AR48152-10; National Center for Complementary and Alternative Medicine (nccam.nih.gov) Grant No. When we look from another prospective- Snayu treatment is also according to Vata Dosha alone. However, the molecular mechanism by which this fibrosis and hypertrophy develop is unknown. Department of Orthopedic Surgery, Rush University Medical Center, Chicago, Illinois, United States of America, Current address: Private Practice, Orange, California, United States of America. Ligamentum flavum thickness was assessed using bilateral medial and lateral measurements. Using MR imaging and custom-developed, spine specific measurement techniques, we examined the thickness of the ligamentum flavum in asymptomatic and chronic low back pain individuals. These changes have been associated with inflammatory changes as well as increased mechanical stresses [2, 3, 5, 6, 9–12]. broad scope, and wide readership – a perfect fit for your research every time. It is worth noting that between both thickness measurements, a moderate correlation coefficient was obtained (r = 0.418. p < 0.01). In (A) the symptomatic medial thickness tended to be larger than in the normal (L1: p = 0.0839, and L2: p = 0.0652, respectively). Contributed equally to this work with: (A) Medial: Asterisks denote significant differences as follows: * p < 0.05; and ** p < 0.001. Our study confirmed an increase in ligamentum flavum thickness both medially and laterally as age increased and as lumbar level increased (caudally), through the L4/5 level. http://www.dynamicdiscdesigns.com Dynamic Disc Designs Corp. Correlation between the ligamentum flavum thickness and disc height was evaluated using linear regression analysis and Pearson’s correlation coefficients. The limitations of our study may stem from the relatively small sample size and availability of MRI image data. Pathology. Hypertrophy of Ligamentum Flavum is a common finding in patients with a herniated disc, protruded disc, prolapsed disc or extruded Disc (Slipped Disc or Slip Disc). Each subject was screened by the authors for pre-existing lumbar spine pathology and pain episodes in order to classify each subject as asymptomatic or symptomatic. 00042801; study no. We believe the medial and lateral measurements provide a better understanding of how ligamentum flavum thickness varies and may affect symptomatology. All other comparisons did not reach significance. Ligamentum flavum thickness was found to significantly increase with older age, lower lumbar level, and chronic low back pain (p < 0.03). These differences reached statistical significance (p = 0.0018 and p < 0.0031, respectively, Fig 2B). However, we have only limited insight into the underlying mechanisms. Ayurvedic Treatment for Ligamentum Flavum Hypertrophy. Materials and Methods Sixty-three individuals were part of this IRB-approved study: twenty-seven with chronic low back pain, and thirty-six as asymptomatic. Yes Nevertheless, there have been few reports describing the natural history of the LF. Over time, these ligaments become thicker as they calcify or enlarge, which can have a noticeable effect on movement and other factors associated with the spine. It is a Latin word means “yellow ligament”. Study Design: Histologic, immunohistochemical (IHC), and enzyme-linked immunosorbent assay analysis of the human ligamentum flavum (LF).. The ligamentum flavum is tendon found in your spinal column. examined 24 individuals using MRI before and after an external axial load. Additionally, a moderate and significant correlation between disc degeneration grade and ligamentum flavum thickness does exist (p <0.001). Previous studies have not agreed upon a uniform method of measuring ligamentum flavum thickness. Error bars span one standard deviation. With redundancy or hypertrophy the ligament is larger and can cause compression on the nerves of … https://doi.org/10.1371/journal.pone.0128321, Academic Editor: Tian-wu Chen, Affiliated Hospital of North Sichuan Medical College, CHINA, Received: November 18, 2014; Accepted: April 26, 2015; Published: May 26, 2015, Copyright: © 2015 Munns et al. Ligamentum flavum thickness was compared between right and left sides, and the data was pooled to form average thickness values. Results for the low back pain group versus the asymptomatic group are summarized in Table 3. (2015) Ligamentum Flavum Hypertrophy in Asymptomatic and Chronic Low Back Pain Subjects. Yes The canal and neuroforamina are patent. Ligamentum flavum hypertrophy is also known as ligamentum flavum thickening. Results are presented as mean and standard deviation. The patient's hypertension and/or unrecognised minor trauma may also have contributed to the pathogenesis of his haematoma. No, Is the Subject Area "Spine" applicable to this article? As the ligamentum flavum (LF) covers most of the posterolateral part of the lumbar spinal canal, its thickening can be attributed to the development of lumbar canal encroachment. Lumbar spinal stenosis represents a significant cause of pain and disability in the aging population. Alejandro A. Espinoza Orías, Contributed reagents/materials/analysis tools: NI GBJA HSA AAEO. Disc height at each level was measured by the least-distance measurement method in three-dimensional models created by CT images taken for the same subject [14, 20]. Disc height at each level was measured by the least-distance measurement method in three-dimensional models created by CT images taken of the same subject. Is the Subject Area "Lower back pain" applicable to this article? With hypertrophy, ligamentum flavum (LF) increases in thickness (size). Using the lateral measurement, the order of ligamentum flavum thickness from least to greatest was L1, L2, L5, L3, and L4. PLOS ONE promises fair, rigorous peer review, This website is provided as a gift by The Cure Back Pain Network. In our series of 63 subjects, we found ligamentum flavum thickness differs between symptomatic and asymptomatic subjects and increases with higher disc degeneration grade, older age and lower lumbar level. In 21 patients (13 male, 8 female) with lumbar spinal stenosis the ligamentum flavum was removed, histologically processed and stained. Ligamentum flavum hypertrophy refers to abnormal thickening of the ligamentum flavum.If severe, it can be associated with central canal stenosis.. The significance level was α = 0.05. However, when conditions are perfectly met, ligamentum flavum thickening can create symptomatic and possibly extreme stenosis symptoms in some patients. Discover a faster, simpler path to publishing in a high-quality journal. Differences based on age, spinal level and disc degeneration grade were analyzed using a one-way ANOVA with a Fischer’s post-hoc test. Go to Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information. Patient has some other reason for central canal stenosis, such as a significant abnormal spinal curvature or spondylolisthesis condition. Slipped Disc Using the lateral measurement, low back pain subjects had thicker ligamentum flavum at L1 (2.92 ± 0.44 mm) and L3 (3.38 ± 0.56 mm) compared to asymptomatic subjects at L1 (2.52 ± 0.51 mm) and L3 (2.96 ± 0.52 mm), respectively. Herniated Disc Frustration The center slice (at mid-disc level) was selected for subsequent analysis from the axial images at each lumbar level from L1/2 to L5/S1. The fact that moderate correlation coefficients were obtained between thickness measurements and disc height also shows that loss of disc height might be one of the contributing factors to instability associated with disc degeneration [18, 19] and stenosis. Data Availability: The data file is available at public repository Figshare.com. Ayurveda is more promising, when it comes to treatment of ligmentum flavum hypertrophy. Medial and lateral ligamentum flavum thickness increased by age group (Table 2). Percentages are calculated with respect to the total number of subjects. The IRB-approved consent documents were signed both by the principal investigator and the subject and a copy was provided to the subjects. Yes The Journal of Orthopaedic Research, a publication of the Orthopaedic Research Society (ORS), is the forum for the rapid publication of high quality reports of new information on the full spectrum of orthopaedic research, including life sciences, engineering, translational, and clinical studies. Error bars span one standard deviation. Objective: The purpose of this study was to determine the level of expression of lysophosphatidic acid (LPA) in the LF from lumbar spinal stenosis (LSS) patients and to analyze the relationship among LPA, LPA receptors (LPARs), and LF hypertrophy. Ligamentum Flavum Hematoma granulomatous change of the ligamentum flavum. Justin J. Munns, Contribution of mechanical stresses to ligamentum flavum thickening has been reported in the literature. When examined by lumbar level, the overall trend was an increase in ligamentum flavum thickness by level caudally from L1/2 (labeled L1) to L4/5 (labeled L4). Although this serves to increase the specificity of our findings, the sensitivity of the study may have been compromised. Odd ratio and 95% confidence interval were calculated. At L3-4, there is mild facet arthropathy, the canal and neuroforamina are patent. Exercises; Relief; Cure Pain Program; Ligamentum Flavum Hypertrophy. here. No, Is the Subject Area "Magnetic resonance imaging" applicable to this article? When it becomes inflamed or lax, it can cause or contribute to central spinal stenosis on the posterior side of the vertebral canal. Hypertrophy of the yellow ligament is a normal process which affects most people to some extent, and some people to a large extent, just like the other typical spinal aging processes, such as degenerative disc disease and osteoarthritis. Ligamentum flavum thickness data were then compared to disc height and disc grade (Pfirrmann classification) to assess for possible correlations. All other comparisons did not reach significance. A total of 63 volunteers were enrolled in this study (Rush University Medical Center IRB Approval No. It was found that low back pain subjects had slightly thicker medial ligamentum flavum in the upper lumbar all levels, except at L4 and L5 where thickness was almost equal and no significant differences were found (p = 0.74 and p = 0.32, respectively). Such stenosis results from ligamentum flavum hypertrophy, inferior articulating process (IAP), facet hypertrophy of the cephalad vertebra, vertebral body osteophytosis, vertebral body compression fractures and herniated nucleus pulposus (HNP). We are proud to help patients for over 15 years and do so without financial gain. Using enhanced MR images as well as bilateral medial and lateral measurements of ligamentum flavum thickness, the current study examined ligamentum flavum thickness across different age groups from 20–60 years of age, gender, and lumbar level in individuals with and without low back pain symptoms. No, Is the Subject Area "Stenosis" applicable to this article? Yes Ligamentum flavum hypertrophy, also known as ligamentum flavum thickening, is a health condition related to the spine and lower back. The current study elegantly shows the role of segmental motion, mechanical stress, and angiogenesis in hypertrophy of the ligamentum flavum. Specifically, we used the following search terms: “ligamentum flavum thickening,” “ligamentum flavum hypertrophy,” “lumbar spine,” “degenerative disk disease,” “disk space height loss,” and “normal lumbar spine MR imaging.” Initially, 854 reports of lumbar spine MR imaging were identified. The condition is actually very simple once it is explained, and luckily is rarely the exclusive source of symptoms. Medial ligamentum flavum thickness was also greater in low back pain subjects, but the difference was not statistically significant. This paper is to describe percutaneous endoscopy in the treatment of lumbar spinal stenosis secondary to ligamentum flavum hypertrophy targeted and to investigate the efficacy and safety of percutaneous endoscopy in the treatment of this kind of lumbar spinal stenosis in elderly patients. It is a degenerative disease which involves the compression of nerves. My Story No, Is the Subject Area "Computed axial tomography" applicable to this article? There are mild disc degenerative changes present at L5/S1 without significant thecal or neural compression here. Dimensions of the bony spinal canal are preserved, structurally the vertebral bodies and neural arches are intact. This important observation may lead to more refined and durable … Analyzed the data: AAEO NI RT. Herniated Disc Pain Turning Head Citation: Munns JJ, Lee JYB, Espinoza Orías AA, Takatori R, Andersson GBJ, An HS, et al. No, PLOS is a nonprofit 501(c)(3) corporation, #C2354500, based in San Francisco, California, US, https://doi.org/10.1371/journal.pone.0128321, http://dx.doi.org/10.6084/m9.figshare.1301159. More importantly, few studies exist that examine the possible correlation between ligamentum flavum thickness and other factors such as disc height and grade of disc degeneration. These differences were not significant at L1 and L2 (p = 0.08 and p = 0.06, respectively), however only L3 reached significance at p = 0.04 (Fig 2A). We are the world’s largest and most respected patient education and advocacy organization in the dorsalgia sector of medicine. Average medial thickness of male subjects (3.30 ± 0.78 mm) was not significantly different from that of females (3.23 ± 0.93 mm; p = .5042). Medial thickness in grade 3 tended to be larger than that in grade 1 (p = 0.0601). PLoS ONE 10(5): While certain studies have utilized an area averaging technique, others have assessed ligamentum flavum thickness using a single measurement located at the approximate “middle” of the ligamentum flavum [2, 5, 13, 15, 16]. The region of interest box (shown as a white square) is selected for analysis. Hypertrophy of Ligament Flavum occurs when the micro or macro traumatic events cause thickening of this ligament. https://doi.org/10.1371/journal.pone.0128321.t001, https://doi.org/10.1371/journal.pone.0128321.t002. Injury, poor posture and longstanding spine conditions are the leading cause of Hypertrophy of Ligamentum Flavum. what does it mean when you have a mild circumferential disc bulge, and mild facet and ligamentum flavum hypertrophy including small facet effusions. Abnormalities of the disk usually do not cause symptoms of central stenosis in a normal-sized canal. Future studies including individuals older than 60 years of age will shed light on the degenerative cascade of the spondylosis including ligamentum flavum hypertrophy. [5] used a multidisciplinary approach to study the pathomechanism of ligamentum hypertrophy and found transforming growth factor-beta to be related to the stimulation of fibrosis and summarized the process of ligamentum flavum hypertrophy as beginning with mechanical stress inducing tissue damage, leading to inflammation and scarring, and finally fibrosis. (A) An original PD MR image. Right and left-sided thickness measures were compiled for average thickness, and are summarized in Table 2. B. Lee, At all levels except L5/S1, medial ligamentum flavum thickness was greater than lateral ligamentum flavum thickness. doi: 10.1007/s00701-010-0839-7 Hypertrophy describes a swelling beyond normal size and possible breakdown of elasticity in the ligament itself at one or more spinal levels. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. When the ligament … Statistical significance was set at the level of p < 0.05. Histologic studies have identified inflammatory markers including tissue inhibitors of matrix metalloproteinases [11, 24], microRNA molecules such as miR-155 [25] and increases in connective tissue growth factor [26] to be related to ligamentum flavum hypertrophy and fibrosis. The calcification, the elastic/collagenous fibre ratio as well as the configuration of the fibres were evaluated with an image analyzing computer. Patient has a congenitally narrowed central canal and moderate to advanced spinal degeneration in addition to ligament hypertrophy. Lumbar Discs Sairyo et al. To determine medial and lateral measurement locations, distances were measured from the lateral border of the ligamentum flavum to midline to define the length; with the medial measurement set at on-third of the length from midline, and the lateral measurement set at two-thirds of the length from midline. This is reasonable, given the close proximity of the lateral measurement to the facet joint, where motion and instability are most appreciable. Disc grade was assessed on the mid-sagittal T2 MRI scan using the Pfirrmann classification [21]. Although pathogenesis of inflammation in the ligamentum flavum appears to be multifactorial, abnormal movements of the motion segment could cause mechanical stress and, in tern, inflammatory reaction. Hypertrophy of the ligamentum flavum (LF) has also been considered as a major cause of LCSS (7). To prove our hypothesis that hypertrophy of the ligamentum flavum is caused by accumulation of inflammation-related scar tissue. Continuing to use this site will imply acceptance of our privacy policy. Risk factors for ligamentum flavum hypertrophy were analyzed using multiple linear regression analysis. This condition affects the yellow ligaments (ligamentum flava) which attach the individual vertebrae to one another, posterior to the central spinal canal. Why We do Flexion Exercises For Lumbar canal Stenosis, Facet Joint arthropathy and Ligamentum flavum hypertrophy. Learn more about us. Ligamentum flavum are the ligaments present in spine. The thickness at the L5/S1 level varied by method but was comparatively thicker using the lateral measurement. Age group differences were not subdivided by level due to the small sample size of patients 50 years and older. These findings of our study, together with the current literature, support the idea that early changes in the ligamentum flavum may play a key role in chronic low back pain symptoms. Analysis of variance and t-tests were carried out to evaluate the relationship between ligamentum flavum thickness and patient variables. Ligamentum flavum hypertrophy is a condition in which the ligamentum flava grows wider and larger and expands toward the central spinal canal.It’s also known as ligamentum flavum thickening. Even though many studies have shown the significance of ligamentum flavum hypertrophy in patients with spinal stenosis or at the advanced stage of spondylosis, few studies have systematically examined ligamentum flavum thickness and its relation to age and lumbar level at early stages of the degenerative cascade [1, 5, 13–16]. Furthermore, attempts to quantify the thickness of the ligamentum flavum have used single measurements, ignoring possible differences in laterality and location of stenosis, i.e. Funding: This work was supported by two National Institutes of Health grants: National Institute for Arthritis and Musculoskeletal and Skin Diseases (www.niams.nih.gov) Grant No. To examine ligamentum flavum thickness using magnetic resonance (MR) images to evaluate its association with low back pain symptoms, age, gender, lumbar level, and disc characteristics.
