Objective. To analyze the frequency of hidden neuraxial pathology in idiopathic scoliosis (IS), to substantiate the need for MRI in IS and to identify promising areas for the use of MRI in the examination of patients with IS.Material and Methods. The literature review was carried out using the PubMed and Google Scholar databases. Of the 780 papers on the research topic, 65 were selected after removing duplicates and checking for inclusion/exclusion criteria. As a result, 49 original studies were included in the analysis. Level of evidence – II.Results. According to modern literature, the main direction of using MRI in idiopathic scoliosis is the search for predictors of latent pathology of the spinal cord and craniovertebral junction. The frequency of neuraxial pathology in idiopathic scoliosis is 8 % for adolescent IS and 16 % for early IS. The main predictors of neuraxial pathology are male sex, early age of deformity onset, left-sided thoracic curve and thoracic hyperkyphosis. MRI in IS may be a useful addition to radiological diagnostic methods to identify risk factors and to study degenerative changes in the spine.Conclusion. MRI of the spine should be performed in the early stages of IS to detect latent spinal cord tethering. In type I Chiari anomalies, there is a possibility that early neurosurgery can prevent the development of scoliosis. The main signs of latent neuraxial pathology in IS are early progression of spinal deformity, left-sided thoracic curve, male gender and thoracic kyphosis over 40° according to Cobb.MRI can be used as an effective non-invasive tool in research aimed at identifying risk factors for IS, including helping to track early degeneration of intervertebral discs.
Objective: Reveal frontal and sagittal patterns of spinal deformity depending on neuromuscular nosology for surgery and outcome planning. The characteristics of spinal deformity vary according to the pathology. In cerebral palsy, muscular dystrophies, and spinal muscular atrophy, specific features of deformities are poorly written, especially in the sagittal profile. Methods: The evaluation criteria were age, gender of the patients, the volume of blood loss, duration of hospitalization, measurement of the deformity curve, thoracic and lumbar kyphosis (Cobb angle), pelvic obliquity concerning the horizontal line, the percentage of curve correction. Cobb angle was measured preoperatively before hospital discharge (up to 21 days postoperatively) and one year after surgery. Results: The cohort of 71 patients with spinal deformities due to neuromuscular diseases included four groups: muscular dystrophy (MD), spinal muscular atrophy (SMA), Duchenne muscular dystrophy (DMD), and cerebral palsy (CP). The most characteristic deformity in the frontal plane was C-shaped thoracolumbar scoliosis with rotation of the pelvis; rotation of the vertebrae increased according to the magnitude of scoliosis. Lumbar hyperlordosis was common in patients with PD, whereas decreased thoracic kyphosis or even thoracic lordosis occurs more frequently in patients with DMD. Moderate correction of scoliosis was observed in all groups. There was no significant improvement in functional status, according to the FIM. Conclusion: The findings showed that rigid hyperlordosis is the main problem of spinal deformities in neuromuscular patients. Scoliosis and pelvic obliquity can be well corrected in NMS by pedicle screw construction with standard maneuvers and pelvic screw fixation. Level of Evidence IV; Lesser quality prospective study.
Objective. To analyze and summarize the data of modern literature on the issues of surgical treatment and natural course of the spine and spinal cord pathology in patients with various types of caudal regression syndrome (CRS).Material and Methods. A systematic review of the literature on the issue of treatment of the spine and spinal cord pathology in patients with CRS was performed. Selection criteria were: articles for the period 2002–2022, original studies of populations/patients with various forms of CRS with a description of treatment methods and long-term results of treatment or observation. A total of 28 articles on the treatment of various forms of CRS with the described results of treatment of 212 patients were analyzed: 29 patients with CRS in combination with open neural tube defects and 183 patients with closed forms of CRS. Evaluation criteria included number of patients, gender, type of spinal cord pathology, type of sacral agenesis, presence of the spine and lower extremities deformities, concomitant pathology, operations performed and their complications, and results.Results. The studied patients underwent the following surgeries on the spine and spinal cord: untethering of the spinal cord, correction and stabilization surgeries on the spine, plasty of the spinal cord herniation, plasty of the terminal meningocele, and removal of the presacarial volumetric mass. The greatest number of complications occurred after operations on the spine and sacrum. The majority of patients (67 %) with sacral agenesis by the end of the follow-up period (average 14 years) walked independently or with the help of devices, and a minority of them (33 %) could not walk. More than half of patients with CRS (67 %) had a neurogenic bladder, urinary incontinence, or suffered from a chronic urinary tract infection. Fecal incontinence and constipation were less common (46 %).Conclusions. Patients with CRS have a good potential for improvement/recovery of walking and pelvic organ dysfunction. This is extremely important to timely carry out multimodality treatment of patients with CRS who have neurosurgical, orthopedic, urogenital and colorectal problems in CRS, and to start early motor rehabilitation and physiotherapy.
Objective. To analyze the current literature dedicated to the etiopathogenesis and development of idiopathic scoliosis.Material and Methods. The analysis includes studies on the etiological factors of idiopathic scoliosis. The search was carried out on eLibrary, PubMed and Google Scholar databases. The review includes research and experimental studies, as well as systematic reviews and meta-analyses. The exclusion criterion is a theoretical work without practical research/experiment to confirm the theory. The depth of analysis is 30 years.Results. Out of 456 papers on the research topic, 153 were selected as meeting the inclusion/exclusion criteria. The main theories of the occurrence of idiopathic scoliosis are identified: genetic, neurogenic, theory of bone and muscle tissue defects, biomechanical, hormonal, evolutionary, and the theory of environmental and lifestyle influences.Conclusions. The term “idiopathic scoliosis” combines a number of diseases with different etiopathogenetic mechanisms of development. Idiopathic scoliosis has a polygenic inheritance. Different genes are responsible for its occurrence in different populations, and the progression mechanisms are triggered by various epigenetic factors. Bone and muscle tissue defects, pathology of the central nervous system, biomechanical disturbances, hormonal and biochemical abnormalities may play a dominant role in some cases of idiopathic scoliosis.
Objective. To analyze possibilities and limitations of various stabilization technologies in the surgical treatment of cervical spine pathology. Material and Methods. Study design: retrospective monocentric observational analysis. Level of evidence: 3b (UK Oxford, version 2009). Diagnostic and treatment data are presented for 433 patients operated on using stabilization systems: patients in Group 1 (n = 228) underwent anterior fixation, those in Group 2 (n = 175)-posterior fixation with polyaxial screw systems, and in Group 3 (n = 30)-combined (anterior and posterior) fixation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
