Study Design: Cross-sectional study. Objective: Recently, there has been a rise in children and adolescents developing low back pain and/or sciatica. Degenerative lumbar spine MRI phenotypes can occur in this population but reports have been sporadic and the true incidence of such spine changes remains debatable. As such, the study aimed to address the epidemiology of MRI phenotypes of the lumbar spine in this young population. Methods: 597 children and adolescents with lumbar MRIs were included in the study. T1- and T2-weighted lumbar images from L1/2 to L5/S1 were analyzed in axial and sagittal planes. Global phenotype assessment was performed of each level and based on established nomenclature protocols. Results: The cohort consisted of 57.3% (342) boys and 42.7% (255) girls, with a mean age of 10.75 ± 5.25 years (range: 0 to 18 years). The prevalence of imaging findings of lumbar disc degeneration (LDD) and lumbar disc herniation (LDH) were 2.2% (95% CI: 0.93–3.43) and 5.8% (95%CI: 2.58-8.99), respectively. There was significant difference between each disc segment from L1/2 to L5/S1 for both LDD and LDH. Schmorl’s nodes were noted in 16 cases (2.7%, youngest case as 15 years), with 11 boys (68.8%) and most frequent segment as L3/4. Modic changes and high-intensity zones were absent in this cohort. Conclusions: LDD can emerge as early as the first decade of life with Schmorl’s nodes, without additional specific phenotypes, including Modic changes and high-intensity zones. The study provides valuable information of a unique age group that is often under-represented but equally important as adults.

High Intensity Zone

Introduction: A high intensity zone (HIZ) in intervertebral disc (IVD) of lumbar spine is a high intensity signal located in the annulus fibrosus of T2-weighted magnetic resonance (MR) imaging. There is limited information on the prevalence of HIZ in lumbar spine in Nepalese population. The aim of this cross-sectional study was to identify the prevalence of HIZ according to the age and its correlation with degenerated disc, disc herniation & bulge and modic changes. Methods: This was a prospective MR based study in 268 patients (1380 IVD) with LBP, Leg pain or numbness. The prevalence and correlation of HIZ , degenerated disc, disc herniation and bulge and modic change was evaluated in 5 age groups (<20, 20-39, 40-59, 60-79, >80). Results: The prevalence of HIZ in patients with LBP was 30.5%. Total 1340 IVD were examined out of which122 had HIZ, 742 had degenerated disc, 688 had disc herniation and bulge and 182 had modic changes. Degenerated disc was observed in 95% (116/122) and 51.3% (626/1218) of disc with and without HIZ respectively. Disc herniation and bulge were observed in 98.3% (120/122) and 46.6% (568/1218) of the disc with and without HIZ, respectively. Modic changes were observed in 11.4% (14/122) and 13.7% (168/1218) of disc with and without HIZ respectively. Conclusions: There was statistically significant correlation between existence of HIZ and degenerated discand disc herniation and bulge, but there was no correlation with the existence of modic changes.

Degenerative disc disease (DDD) is a progressive pathological condition observed in 60 to 80% of the population [1]. It involves changes in both the biochemistry and morphology of the intervertebral disc and is associated with chronic low back pain, sciatica and adult scoliosis [2,3]. The most accepted theory of the effects of DDD on the kinematics of the spine is that proposed by Kirkaldy-Willis and Farfan which states that the condition initiates as a temporary dysfunction, followed by instability and then re-stabilization as the disease progresses [4]. Although there is no clear relationship between disc degeneration and the mechanical behavior of the lumbar spine, abnormal motion patterns either in the form of increased motion or erratic motion have been reported from studies on human cadaveric motion segments [5,6]. To date however no study has looked at how disc degeneration affects the adjacent segment mechanics. IN vivo testing is difficult for these purposes given that specimens are generally obtained from people at the later stages of life and consequently often display multiple pathologies. A finite element model is a viable alternative to study the mechanics of the segments adjacent to the diseased disc. It is hypothesized that moderate degeneration at one level will alter the kinematics of the whole lumbar spine.

Abstract Background The relationship between spinal sagittal subtypes and lumbar disc degeneration is unclear. Thus, we aimed to investigate the relationship between lumbar intervertebral disc degeneration and age in asymptomatic healthy individuals with different sagittal alignments. Methods In this cross-sectional observational study, we examined 209 asymptomatic young and middle-aged volunteers (123 women and 86 men) who were divided into the following three groups according to age: groups A (20–30 years), B (31–40 years), and C (41–50 years). The volunteers underwent full-spine standing lateral radiography and magnetic resonance imaging (MRI, 3.0 T) of the lumbar spine. Based on panoramic radiography, two observers measured the spinopelvic parameters and classified the spine into Roussouly subtypes. The degree of disc degeneration was assessed based on T2-weighted images according to the Pfirrmann classification. Results There was a statistically significant difference in the degree of degeneration of type I spine between groups B and C at L4-L5 (P < 0.03) and L5-S1 (P < 0.01) and between groups A and C at L1-L2 (P < 0.04) and L4-L5 (P < 0.01). The degeneration degree of type II spine at all levels were significantly different between groups A and C. No statistically significant difference was found between groups A and B in all subtypes except for type II spine at L1-L2 (P < 0.04). A significant difference was found at four levels between groups B and C in type III spine (P < 0.05) and between groups A and C. For type IV spine, there was a significant difference in the degree of degeneration at L4-L5 (P < 0.02) between groups A and C. Moreover, almost all single parameters were not strongly correlated with the degree of disc degeneration. Conclusion The different spinal subtypes have characteristics of lumbar disc degeneration at specific levels with age. We considered that spinal classification could be used as a predictor of lumbar disc degeneration. Our data may be helpful to increase awareness of the relationship between spinal subtypes and lumbar disc degeneration. Level of evidence 3

The aim of the present study was to evaluate the efficiency of high intensity laser and ultrasound therapy in patients who were diagnosed with lumbar disc herniation and who were capable of performing physical exercises. 65 patients diagnosed with lumbar disc were included in the study. The patients were randomly divided into three groups: Group 1 received 10 sessions of high intensity laser to the lumbar region, Group 2 received 10 sessions of ultrasound, and Group 3 received medical therapy for 10 days and isometric lumbar exercises. The efficacy of the treatment modalities was compared with the assessment of the patients before the therapy at the end of the therapy, and in third month after the therapy. Comparing the changes between groups, statically significant difference was observed in MH (mental health) parameter before treatment between Groups 1 and 2 and in MH parameter and VAS score in third month of the therapy between Groups 2 and 3. However, the evaluation of the patients after ten days of treatment did not show significant differences between the groups compared to baseline values. We found that HILT, ultrasound, and exercise were efficient therapies for lumbar discopathy but HILT and ultrasound had longer effect on some parameters.
