Correlation between facet tropism and lumbar disc herniation

Abstract Purpose The relationship between facet tropism (FT) and lumbar disc herniation (LDH) is not clear. In the present study, MRI was used to assess the relationship between lumbar facet joint tropism and disc herniation. This paper is the first to assess the relationship between facet joint tropism and LDH from the sagittal view. Methods 122 patients (154 segments) with lumbar disc herniation and 102 normal subjects (306 segments) who visited our hospital from 01-Jan-2020 to 01-Apr-2020 were included in this study. The axial and sagittal angles of facet joints were measured using an MRI scan. The difference of 10° in facet angles between left and right was defined as lumbar facet tropism. The relationship between the two was analyzed. Results In the axial, 95/154 segments with lumbar disc herniation had FT whereas, 48/258 segments had FT in the normal segments(p < 0.01). In the sagittal, 61/154 segments with lumbar disc herniation had FT and 48/306 had FT in the control(p < 0.01). Conclusion The proportion of FT is better in patients with lumbar disc herniation, and there is a significant correlation between FT and lumbar disc herniation.

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 > 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.

OBJECTIVE The role of facet tropism (FT) in lumbar disc herniation (LDH) is ambiguous. The present study aimed to investigate the association between FT and LDH in adolescents. METHODS This study included 65 adolescents with LDH with 1- or 2-level LDH, or both. Facet angles were measured with MRI. FT was defined as asymmetry of 10° between the left and right side. The same levels of 30 healthy persons who had no lumbar lesions were used as controls. Statistical analysis was performed using the chi-square test. RESULTS FT was identified in 16 of 39 patients with LDH in L4–5 and in 3 of 30 controls (p = 0.006, OR 6.261, 95% CI 1.619–24.217). It was also identified in 12 of 27 patients with LDH in L5–S1 and in 4 of 30 controls (p = 0.017, OR 5.200, 95% CI 1.420–19.039). One patient had LDH in both L4–5 and L5–S1. CONCLUSIONS FT is associated with LDH in both L4–5 and L5–S1 levels in adolescents.

Facet Tropism

Background: Intervertebral disc herniation is a degenerative lumbar disease and a common pathology of skeletal system. Currently, most experts assume that facet tropism may affect lumbar degenerative diseases. Considering the previous inconsistent findings on the relationship of facet tropism, the present study was aimed to find the association between facet tropism and lumbar disc herniation.Methods: Patients with low back pain attending the OPD of orthopaedics department, with signs and symptoms of disc herniation were sent for magnetic resonance imaging (MRI). 72 patients with single level disc herniation were included in the study. Facet angles were measured using MRI of 1.5 T using the method described by Karacan et al. Facet tropism was defined as difference of 100 or more in facet joint angles between right and left sides.Results: 45 of the 72 cases (50%) who presented with lumbar disc herniation (LDH) had tropism while none (0%) at the control level did. This association was not statistically significant (p=0.983). Significant association was found between the side of disc herniation and the distribution of the more coronal or sagittal facing facet (p=0.024).Conclusions: Despite the presence of tropism only in the intervertebral segments affected with LDH in our study, the association between tropism and LDH was not statistically significant.

This work aimed to explore the relationship between spine surgery lumbar facet joint (LFJ) and lumbar disc herniation (LDH) via compressed sensing algorithm-based MRI images to analyze the clinical symptoms of patients with residual neurological symptoms after LDH. Under weighted BM3D denoising, Epigraph method was introduced to establish the novel CSMRI reconstruction algorithm (BEMRI). 127 patients with LDH were taken as the research objects. The BEMRI algorithm was compared with others regarding peak signal-to-noise ratio (PSNR) and structural similarity index (SSIM). Patients’ bilateral LFJ angles were compared. The relationships between LFJ angles, lumbar disc degeneration, and LFJ degeneration were analyzed. It turned out that the PSNR and SSIM of BEMRI algorithm were evidently superior to those of other algorithms. The proportion of patients with grade IV degeneration was at most 31.76%. Lumbar disc grading was positively correlated with change grading of LFJ degeneration ( P < 0.001 ). LFJ asymmetry was positively correlated with LFJ degeneration grade and LDH ( P < 0.001 ). Incidence of residual neurological symptoms in patients aged 61–70 years was as high as 63.77%. The proportion of patients with severe urinary excretion disorders was 71.96%. Therefore, the BEMRI algorithm improved the quality of MRI images. Degeneration of LDH was positively correlated with degeneration of LFJ. Asymmetry of LFJ was notably positively correlated with the degeneration of LFJ and LDH. Patients aged 61–70 years had a high incidence of residual neurological symptoms after surgery, most of which were manifested as urinary excretion disorders.

Abstract Background: Facet joint parameters have been discussed as substantial factors in the development of LDH. However, the correlation between facet joint parameters and the location of LDH in the corresponding segment is still unclear. The objective of this study was to demonstrate a clearly relationship between facet orientation (FO), facet tropism (FT) and lumbar disc herniation (LDH) in young individuals.Methods: Between June 2017 and December 2019, 529 patients having single-level LDH (L4-5 or L5-S1) between 18 and 35 years old with a less than 2 years clinical history were included. Another 122 age-matched patients with no LDH were enrolled as the control group (N-LDH group). Based on the location of herniation, cases in LDH group were divided into three groups (LDHL, LDHR, and LDHM). We investigated the correlation between facet joint parameters and the location of LDH.Results: The FOA in L4-5 and L5-S1 level were significantly lower while FT were higher in LDH group than N-LDH group respectively. In terms of the correlation between the facet joint parameters and the location of LDH, the level of LDH, the FOL, FOR, and FT were significantly varied among the three groups. There is a significant association between the different location of LDH and different FO of bilateral facet joints in L4-5 while not in L5-S1 level.Conclusion: The facet joint parameters abnormality have an significant association with the development of LDH. Young individuals with higher FT and/or lower FO should be paid more attention to preventing the occurrence of LDH. There was more location of IVD herniated on the ipsilateral location with lower FO of facet joint when FT existed in L4-5 level.

ABSTRACT Objective: To correlate facet tropism with the side and location of the intervertebral disc in which the lumbar disc herniation occurred. Methods: A retrospective descriptive study that evaluated Magnetic Resonance Imaging of 255 patients with lumbar disc herniation undergoing surgical treatment with the Spine Group of the Hospital Ortopédico de Passo Fundo between 2002 and 2014. The total patient number was stratified according to the side affected by the herniated disc (right or left), location of the hernia in the intervertebral disc (central, centrolateral, foraminal and extraforaminal) and demographic data, such as age, gender etc. The degree of facet joint tropism was measured by the Karakan method and classified as mild (difference less than 7º); moderate (between 7º and 15º) and severe (difference greater than 15º). Results: A statistical significant relationship (p= 0.023) was observed between the facet joint tropism and the side where the lumbar disc herniation occurred. No correlation was found between facet joint tropism and location of the herniation on the intervertebral disc. Conclusions: The degree of facet tropism presents a statistical significant correlation with the side of the intervertebral disc in which the lumbar disc herniation will develop. Level of Evidence: II. Type of study: Retrospective study.

The Relationship

Little is known about the effect of lumbar intervertebral disc herniation (LDH) on lumbar bone mineral density (BMD), and few previous studies have used quantitative computed tomography (QCT) to assess whether the staging of LDH correlates with lumbar vertebral trabecular volumetric bone mineral density (Trab.vBMD). To explore the relationship between lumbar Trab.vBMD and LDH, seven hundred and fifty-four healthy participants aged 20–60 years were enrolled in the study from an ongoing study on the degeneration of the spine and knee between June 2014 and 2017. QCT was used to measure L2–4 Trab.vBMD and lumbar spine magnetic resonance images (MRI) were performed to assess the incidence of disc herniation. After 9 exclusions, a total of 322 men and 423 women remained. The men and women were divided into younger (age 20–39 years) and older (age 40–60 years) groups and further into those without LDH, with a single LDH segment, and with ≥2 segments. Covariance analysis was used to adjust for the effects of age, BMI, waistline, and hipline on the relationship between Trab.vBMD and LDH. Forty-one younger men (25.0%) and 59 older men (37.3%) had at least one LDH segment. Amongst the women, the numbers were 46 (22.5%) and 80 (36.4%), respectively. Although there were differences in the characteristics data between men and women, the difference in Trab.vBMD between those without LDH and those with single and ≥2 segments was not statistically significant (p > 0.05). These results remained not statistically significant after further adjusting for covariates (p > 0.05). No associations between lumbar disc herniation and vertebral trabecular volumetric bone mineral density were observed in either men or women.
