Сomputed tomography (CT) is widely used in the diagnosis of  degenerative pathology of the lumbar spine, but the relationship  between clinical manifestations of lumbar stenosis and its anatomical prerequisites has not been sufficiently studied to date.The objective: to determine the significance of the morphometric  parameters of lumbar stenosis according to CT scans and to  establish their relationship with the prevailing symptoms of the disease.Material and methods. Seventy-five consecutive patients with  clinically significant lumbar stenosis who underwent CT scan before  surgery were enrolled in this study. The average values of thirteen  different morphometric parameters were calculated at LIII–SI levels of the intervertebral discs and of the pedicels in the axial and sagittal views. The possibility of classification of clinical observations and the correlation of morphometric parameters with the clinical forms of lumbar stenosis were investigated using discriminant and logistic regression analysis. Results. CT scan with high probability allocates patients with  predominant symptoms of neurogenic claudication or bilateral  radiculopathy. The most significant morphometric predictors of this  clinical group are the depth of the lateral recesses and the cross-sectional area of the spinal canal.Conclusion. CT scan significantly expands the informative value of  magnetic resonance imaging and can be used in planning the  decompressive stage of the surgery intervention in patients with lumbar spinal canal stenosis.

Abstract Background Back pain often arises from degenerative changes in lumbar intervertebral discs and their adjacent endplates. A painful endplate is not easy to identify in patients, but could possibly be revealed by inflammatory-like ‘Modic’ changes and by a ‘vacuum phenomenon’ within the disc. We hypothesize that Modic changes and a VP often co-exist in those lumbar levels most closely associated with back pain Methods We scanned 1023 consecutive inpatients of the Department of Orthopaedics from 2015 August to 2018 August, all patients suffered from lumbar degenerative diseases, whether the patients had back pain or not were evaluated, and the prevalence and location of vacuum phenomenon(VP) and Modic changes were compared at each spinal level. Results 5115 discs were studied from 1023 patients. The number of discs showed to have a VP was 430 using CT, of the 430 discs with a CT-diagnosed VP, 116 were L4-5, and 171 were L5-S1. 522 of the 5115 discs exhibited Modic changes, with prevalence of type I, type II and type III Modic changes being 1.6%, 8.2% and 0.4% respectively. Modic changes usually occurred adjacent to L4-5 discs or L5-S1 discs. The prevalence of back pain was higher in the VP group than no-VP group, VP were significantly associated with Modic changes Type II at L4/5 and at L5/S1. Conclusion VP are closely associated with back pain and Modic changes in the lower lumbar spine. Further investigations may be warranted when radiographs or CT identify a VP in a lumbar disc.

Introduction. Analysis of the modern literature shows that the number of children complaining of low back pain of varying intensity in the spine increases annually. Publications on the surgical treatment of juvenile osteochondrosis were scarce. Currently, there are no algorithms for choosing a surgical treatment for children and adolescents with lumbar spine pathology, particularly high-grade listhesis, methods and terms of surgical treatment, and the use of reduction maneuvers remain debatable. There are no high-quality evidence studies. Aim. This study aimed to summarize the experience of treatment of children and adolescents with pathology of the lower lumbar spine. Material and methods. We performed a retrospective analysis of the treatment outcomes in patients with lower lumbar spine pathology who were younger than 18 years and who underwent surgery in the Neurosurgical Department No. 2 of the Tsiv’yan Novosibirsk Research Institute of Traumatology and Orthopedics between 2008 and 2018. The mean age of the patients was 15.5 years. We structured pathologies and interventions in children and adolescents and evaluated the clinical and radiological outcomes of treatment and the rate of intraoperative and postoperative complications. Results and discussion. From 2008 to 2018, 11,428 patients with degenerative spine disease and isthmic/dysplastic spondylolisthesis underwent surgery at the Neurosurgical Department No. 2. Of these, 55 (0.5%) patients were younger than 18 years. In all patients, surgical treatment led to pain relief and physical activity recovery. Decompression/stabilization surgery through the posterior approach enabled formation of an artificial block in 100% of cases. The rate of surgical treatment complications was 8.6% and 28.6% in children and adolescents with herniated lumbar intervertebral discs and spondylolisthesis, respectively. Conclusion. Surgical treatment of children and adolescents with pathology of the lower lumbar spine demonstrated an excellent clinical outcome. Disc herniation did not recur 4.9 years after decompression surgery for herniated lumbar intervertebral discs. Decompression/stabilization surgery through the posterior approach in children and adolescents with spondylolisthesis facilitated abolition of pain, regression of neurological disorders, full recovery of physical activity, and formation of a reliable artificial block. Potential complications were resolved without consequences and did not downplay the importance of surgical techniques in the treatment of this group of patients.

Despite the increasing recognition of the functional and clinical importance of lumbar lordosis, little is known about its description, particularly in Egypt. At the same time, magnetic resonance imaging (MRI) has been introduced as a noninvasive diagnostic technique. The aim of this study was to investigate the anatomy of the lumbar lordosis using midsagittal MRIs. Normal lumbar spine MRIs obtained from 93 individuals (46 males, 47 females; 25–57 years old) were evaluated retrospectively. The lumbar spine curvature and its segments “vertebrae and discs” were described and measured. The lumbar lordosis angle (LLA) was larger in females than in males. Its mean values increased by age. The lumbar height (LH) was longer in males than in females. At the same time, the lumbar breadth (LB) was higher in females than in males. Lumbar index (LI = LB/LH × 100) showed significant gender differences (P<0.0001). Lordosis was formed by wedging of intervertebral discs and bodies of lower lumbar vertebrae. In conclusion, MRI might clearly reveal the anatomy of the lumbar lordosis. Use of LI in association with LLA could be useful in evaluation of lumbar lordosis.

Sitting is the most frequently performed posture of everyday life. Biomechanical interactions with office chairs have therefore a long-term effect on our musculoskeletal system and ultimately on our health and wellbeing. This paper highlights the kinematic effect of office chairs on the spinal column and its single segments. Novel chair concepts with multiple degrees of freedom provide enhanced spinal mobility. The angular changes of the spinal column in the sagittal plane in three different sitting positions (forward inclined, reclined, and upright) for six healthy subjects (aged 23 to 45 years) were determined using an open magnetic resonance imaging (MRI) scanner. An MRI-compatible and commercially available office chair was adapted for use in the scanner. The midpoint coordinates of the vertebral bodies, the wedge angles of the intervertebral discs, and the lumbar lordotic angle were analysed. The mean lordotic angles were16.0±8.5∘(mean ± standard deviation) in a forward inclined position,24.7±8.3∘in an upright position, and28.7±8.1∘in a reclined position. All segments from T10-T11 to L5-S1 were involved in movement during positional changes, whereas the range of motion in the lower lumbar segments was increased in comparison to the upper segments.
