Abstract Background The influence of spinopelvic morphology on the Chinese elderly LDH population was not clear. The purpose of this study is to explore its influence on the characteristics of lumbar disc herniation or degeneration. Methods 212 elderly patients with LDH and 213 asymptomatic volunteers were involved. Spinal parameters were measured on full-length X-ray and compared between two populations. In herniated group, sagittal profiles were determined according to the Roussouly classification, the degenerative grades, the herniated location and the number of intervertebral lumbar disc degeneration were evaluated from the L1 to S1 on MRI scans. The differences on them among Roussouly types were analyzed. Results There were no significant differences in BMI, the mean value of age and sex distribution between two populations. Patients were found to have significantly smaller TK, LL, and SS than those volunteers (p < 0.05), while contradicting observations on PT and TPA were obtained (p < 0.05). Roussouly type 1 and type 2 ( 50.4% and 28.7% respectively) are predominant in the LDH population and the proportion of type 1 in elderly LDH is further increased. Subjects with LDH in type 1 and 2 had lower mean herniated locations and fewer mean herniated numbers than those with type 3 and 4. Conclusions Sagittal spinopelvic parameters were found to be significantly different in elderly LDH patients and asymptomatic volunteers. There were significant differences in the Roussouly distribution among different age groups of LDH. Different Roussouly subtypes have different effects on lumbar disc degeneration and herniation.

Objective:To report an unusual case of large synchronous lumbar disc herniation in adult twins.Methods:Case report and relevant literature review.Results:The authors report a case of adult female monozygotic twins who synchronously presented with huge lumbar disc herniation. Rather than being a curious coincidence, this case highlights the potential importance of hereditary factors in the causation of lumbar disc degeneration. The relevant literature regarding the role of genetic factors and their relationship to other risk factors in lumbar disc degeneration is reviewed and discussed.Conclusion:Synchronous lumbar disc herniation in adult twins is a rare event. It, however, sheds light on the role of genetic factors in disc degeneration.

Objective Pediatric lumbar disc herniation (LDH), although uncommon, causes significant pain, discomfort, and sometimes disability. We examined the efficacy of percutaneous endoscopic lumbar discectomy (PELD) for pediatric LDH and the degree of lumbar disc degeneration at 1 year after PELD. Methods We retrospectively reviewed the data of pediatric patients with LDH who underwent PELD from December 2007 to July 2018. The patients’ symptoms, physical examination findings, clinical images, visual analog scale (VAS) scores, Oswestry Disability Index (ODI), and perioperative results (blood loss, length of hospital stay, and complications) were obtained from the medical records. Lumbar disc degeneration was graded using the modified Pfirrmann grading system at the 1-year postoperative magnetic resonance imaging (MRI) examination. Results Six boys and four girls who underwent PELD were evaluated. The patients’ mean age was 15.6 years (range, 13–17 years). The mean VAS score for low back pain, mean VAS score for lower limb pain, and mean ODI preoperatively and 1 year postoperatively were 6.2 and 0.3, 6.9 and 0.5, and 20 and 0.1, respectively. MRI showed significant disc degeneration after PELD. Conclusions Treating pediatric LDH with PELD is safe and effective. It relieves pain and reduces disability. However, lumbar disc degeneration still occurs.

Abstract Background: As an important anatomic factor in the process of Lumbar disc herniation (LDH), the correlation between endplate sagittal morphology and intervertebral disc degeneration (IDD) is unclear. and research on imaging data of lumbar endplate in patients with LDH is still insufficient. Our study aimed to observe the morphological change of the lower lumbar endplate (L3-S1) in patients with LDH on magnetic resonance imaging (MRI), and analyze its correlation with the degree of IDD.Methods/Design: All 116 patients were included. Based on their MRI, we divided endplates into three types (concave, flat and irregular), assigned intervertebral discs with Grade I-V given 1-5 points successively according to Pfirrmann system, and determined whether there was Modic change of each endplate. The correlation between the morphology of endplate and the degree of IDD was analyzed.Results: There were excellent inter-observer agreement for each item we analyzed (ICC > 0.75). Concave endplate appeared most frequently (187, 53.7%) and mainly distributed in L3/4 and L4/5, while irregular endplate was the least common type (54, 15.5%) and mainly concentrated in L5/S1. The IDD degree of corresponding disc increased gradually from concave (3.27 ± 0.81) to irregular endplates (4.25 ± 0.79) (P < 0.05). Irregular endplates were more likely to have Modic changes than concave and flat endplates (P < 0.05). Conclusion: The sagittal morphology of lower lumbar endplate is related to Modic changes and degree of IDD (based on Pfirrmann grading system) in patients with LDH, and the concave endplate mostly reflects a lower degree of lumbar disc degeneration, which has substantial clinical significance.

Objectives: Resistance training, such as weightlifting, in child and adolescent athletes has been considered unsafe, leading to injuries to the musculoskeletal system and growth plate, and to low back pain (LBP). We focused on the lumbar vertebrae, as these are most frequently injured in weightlifting, and prospectively investigated LBP and abnormal lumbar findings in child and adolescent weightlifters. The purpose of this 4-year cohort study was to assess the incidence and characteristics of LBP and abnormal lumbar findings in child and adolescent weightlifting athletes using medical questionnaires and magnetic resonance imaging (MRI). This study was conducted to evaluate subclinical sports injuries. In the absence of reports on long-term implications of resistance training, the safety and validity of resistance training in children and adolescents, especially weightlifting at the competition level, has remained controversial. The findings may help prevent competition-specific injuries and improve performance levels. Methods: This prospective 4-year cohort study was conducted between 2014 and 2017. Twelve participants (6 boys and 6 girls) were enrolled. The participants were either children or adolescents without history of lumbar disease or surgery who participated in weightlifting for at least 2 years. The mean age of the participants at the start of this study was 11.4±2.0 years. Annual medical questionnaires and lumbar examinations using MRI were performed during the 4-year follow-up. The assessment items included a medical questionnaire, which was used to record the practice frequency and presence of LBP each year, and MRI findings. On MRI, lumbar spondylolysis, disc herniation, and lumbar disc degeneration at all lumbar vertebral levels (L1 to S1) in the sagittal and coronal plane were assessed. Pfirrmann classification was used for the assessment of lumbar disc degeneration. MRI findings were interpreted by two orthopedic surgeons; one was a specialist in spine surgery, and the other was an experienced orthopedic surgeon. Both readers were unaware of the participant’s other findings. Inter-reader and intra-reader agreements were assessed using the κ value. Results: The participants practiced approximately 2 hours per day for about 5 days per week under the guidance of a team coach. At the start of this study, there were no positive findings of LBP, lumbar spondylolysis, or disc herniation on MRI. Lumbar disc degeneration on MRI was observed in only 2 participants. The grade of degeneration was grade 2. During the 4-year study, LBP was confirmed in 5 participants, lumbar spondylolysis in 5, and lumbar disc herniation in 3; 1 of the herniation cases required operative treatment, and lumbar disc degenerations was found in all participants (Table) . In lumbar disc degenerations, 8 participants had lumbar disc degeneration in the second year, with 9 in the third year, and 12 (including 5 with grade 3 degeneration) in the final year. Lumbar disc degeneration changes were irreversible. The κ value of inter-reader agreement was 0.53, with 0.78 for intra-reader agreement. Conclusion: This prospective 4-year cohort study of 12 child and adolescent weightlifters revealed that abnormal lumbar findings occurred in all cases when assessed with MRI, and that the abnormal changes were irreversible. Regardless of the presence or absence of symptoms, resistance training at the competition level is likely to cause irreversible changes in the lumbar vertebrae. [Table: see text]

BACKGROUND: Lumbar disc herniation (LDH) occurs owing to the inability of the posterior longitudinal ligament (PLL) to preserve the disc material within the intervertebral space. There is apparently no study that has investigated the histopathological changes occurring in both PLL and disc material in patients with LDH. OBJECTIVE: Investigate and compare the histopathological changes occurring in PLL and disc material of the patients who underwent a surgical operation for LDH. DESIGN: Descriptive, cross-sectional. SETTING: Pathology and neurosurgery departments of a tertiary health care institution PATIENTS AND METHODS: The study included patients who underwent surgical operation for LDH from January 2018 to May 2019 and whose PLL and disc material were removed together, and had disc degeneration findings that were radiologically and histologically concordant. MAIN OUTCOME MEASURES: PLL degeneration scores according to the histopathological findings, changes in disc materials according to the MRI findings, disc degeneration scores according to the histo-pathological findings. SAMPLE SIZE: 50. RESULTS: MRI and histological examinations showed fully degenerated black discs (Grade 2) in 12 patients, partially degenerated discs (Grade 1) in 29 patients and fresh/acute discs (Grade 0) in 9 patients. The PLL showed grade 0 degeneration in 2 patients, grade 1 degeneration in 23 patients, and grade 2 degeneration in 25 patients. PLL degeneration grades were higher than the disc degeneration grades ( P =.002). CONCLUSION: Longitudinal ligament degeneration can play a significant role in the pathogenesis of LDH. To the best of our knowledge, this study represents the first to focus on the histopathological changes occurring in both the PLL and disc material in patients with LDH. LIMITATIONS: Small sample, retrospective CONFLICT OF INTEREST: None.
