To search for normal parameters of the sagittal balance of the cervical spine in children, to analyze their dynamics in different periods of childhood, and to compare them with the norm given for the adult population.Material and Methods. To assess the parameters of the sagittal balance of the cervical spine, radiographs were selected that were initially evaluated by radiologists as a variant of the norm. The final sample consisted of 73 radiographs of 44 girls and 29 boys aged 4 to 17 years.Digital radiographs were used to evaluate the 10 most common parameters presented in publications: the angular values of Oc–C2, C2–C7, C7S, Th1S, TIA, NT, CeT, CrT, SCA, as well as the cSVA distance measured in mm. The measurements were carried out independently by 3 specialists working with pediatric patients: an orthopedic surgeon (experience up to 5 years), an orthopedic surgeon (experience more than 15 years), and a radiologist specializing in skeletal pathology (experience more than 5 years). The obtained results weresubjected to statistical processing.Results. Using multivariate analysis of variance, the presence of a statistically significant difference in age was revealed only for cSVA, gender differences were revealed for 6 out of 10 parameters. Most of the parameters showed good and satisfactory agreement between specialists.A very strong correlation was established between the parameters C7S and Th1S, which correlates with the adjacent position of the vertebrae.The C2–C7 and SCA parameters have a strong positive correlation with each other, the CeT parameter is strongly negatively correlated with both of them. The TIA has a strong negative correlation with SCA and a moderate positive correlation with NT, CeT, C7S, and Th1S. The cSVA and CrT values strongly correlate only with each other. Comparison of the obtained parameters of the sagittal balancein children with the data in scientific publications on the adult population revealed statistically significant differences in the values of 6 out of 10 of them.Conclusion. The age norms of the main parameters of the sagittal balance for children, and their gender differences were determined. Their difference from the normal parameters of the adult population was established, which requires that these features be taken into accountin clinical practice.","PeriodicalId":337711,"journal":{"name":"Hirurgiâ pozvonočnika (Spine Surgery)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134031077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design: Single-center, non-randomized continuous retrospective cohort study. The level of evidence is 3b (UK Oxford, version 2009). A total of 57 patients (10 men and 47 women) were operated for degenerative scoliosis of the lumbar spine using minimally invasive techniques. The quality of life indicators using ODI, SF-36, VAS, as well as linear and angulometric parameters of the spine were studied.Results. The age of patients ranged from 37 to 81 years (62/62 [55; 67], hereinafter the data format is mean/median [1; 3rd quartile]). In the postoperative period, patients operated on with MIS techniques showed a statistically significant decrease in pain by 4.3/4.0 [3; 6] points in the lumbar spine, and by 4.3/4.0 [3; 6] points in the legs. Quality of life indicators according to ODI improved by 24/23 [19;  29], and the level of functional adaptation according to the SF-36 questionnaire – by 18/18 [14; 21] in terms of physical parameters and by 18/20 [16; 23] in terms of mental parameters.

Pola classification (2017) and to assess expert consensus on the diagnosis and treatment of infectious lesions of the spine in the national professional community.Material and Methods. A clinical and radiological database on 15 cases of infectious spondylitis, as well as the information about original article by Pola and a Russian translation of the classification and tactical tables from this article, were distributed to 408 orthopedic traumatologists, neurosurgeons and radiologists who have experience in treating patients with spinal pathology and whose data are available in the registers of the relevant professional associations of the Russian Federation. The coincidence/difference in the responses concerning the definition of lesion types and the choice of treatment tactics, as well as proposals for the use of classification were assessed.Results. Answers were obtained from 37 respondents from 11 regions of the Russian Federation. The general interobserver agreement index (Fleiss kappa) for all types of spondylodiscitis was 0.388 (95 % CI 0.374–0.402), including for lesion types: type A – 0.480 (95 % CI 0.460–0.499, type B – 0.300 (95 % CI 0.281–0.320), and type C – 0.399 (95 % CI 0.380–0.419). Agreement levels were higher among radiologists (type A – 0.486, type B – 0.484, and type C – 0.477), orthopedic traumatologists (type A – 0.474, type B – 0.380, and type C – 0.479), and specialists with clinical experience less than 10 years (type A – 0.550, type B – 0.318, and type C – 0.437). The pooled data for all 12 lesion subtypes showed general poor agreement (k = 0.247, CI 0.240–0.253), satisfactory level was found for B3.2 type (k = 0.561, CI 0.542–0.581), good agreement (k > 0.61) was achieved between orthopedic traumatologists for type B3.2 and between radiologists for B3.1 and B3.2 lesion types. Respondents refused to use basic treatment options for type A in 15.1 %, type B in 7.5 % and type C in 3.2 % of answers, while indicating the need for interventions through anterior approach in 24.7 %, 43.0 % and 46.2 %, respectively. Limitations of the classification use depending on the localization and etiology of spondylitis were noted. Authors recommended taking into account the presence of systemic inflammatory response syndrome, mandatory CT scanning, clarification of spinal instability criteria, and the addition of anterior surgical interventions to the treatment algorithm.Conclusion. The Pola classification of spondylodiscitis is currently considered the most successful for tactical algorithms and implementation in broad clinical practice for spondylodiscitis.

To analyze long-term results of surgical correction of kyphosis due to Scheuermann’s disease.Material and Methods. Design: retrospective cohort study. The study group included 43 patients (m/f ratio, 34/9). The mean age was 19.1 (14–32) years; the mean postoperative follow-up was 6 ± 10 (5–20) years. Two-stage surgery including discectomy and interbody fusion followed by posterior correction and fusion was conducted in 35 cases (Group A). Eight patients (Group B) underwent only posterior correction and spinal fusion. The following parameters were determined for each patient: thoracic kyphosis (TK), lumbar lordosis (LL) (scoliotic deformity of the thoracic/thoracolumbar spine, if the curve magnitude was > 5°), sagittal vertical axis (SVA), sagittal stable vertebra (SSV), first lordotic vertebra (FLV), proximal junctional angle (PJA) and distal junctional angle (DJA). All measurements were performed immediately before surgery, one week after surgery, and at the end of the follow-up period. All patients answered the SRS-24 questionnaire after surgery and at end of the follow-up period.Results. Groups were comparable in terms of age and gender of patients, body mass index and initial Cobb angle (p < 0.05). The curve decreased from 77.8° to 40.7° in Group A and from 81.7° to 41.6° in Group B. The loss of correction was 9.1° and 6.0° in groups A and B, respectively. The parameters of lumbar lordosis remained normal during the follow-up period. At implant density less than 1.2, deformity correction and correction loss were 44.5° (54.7 %) and 3.9°, respectively (p < 0.05). Proximal junctional kyphosis (PJK) was detected in 21 out of 43 patients (48.8 %). The frequency of PJK was 45.4 % among patients whose upper end vertebra was included in the fusion and 60 % among those whose upper end vertebra was not included. PJK developed in eight (47.8 %) out of 17 patients with kyphosis correction ≥ 50 % and in 13 (50.0 %) of those with correction < 50 %. The rate of DJK development was 39.5 %. The lower instrumented vertebra (LIV) was located proximal to the sagittal stable vertebra in 16 cases, with 12 (75 %) of them being diagnosed with DJK. In 27 patients, LIV was located either at the SSV level or distal to it, the number of DJK cases was 5 (18.5 %); p < 0.05. Only two patients with complications required unplanned interventions.

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.","PeriodicalId":337711,"journal":{"name":"Hirurgiâ pozvonočnika (Spine Surgery)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114676306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To analyze clinical and morphological features of neurogenic hourglass tumors in the thoracic spine and their impact on outcomes of treatment through posterior surgical approaches.Material and Methods. The results of surgical treatment of 295 patients with tumors growing from the nerve roots of the thoracic spinal cord were studied. In 63 (21 %) of them, tumors of the spinal nerves were diagnosed. The vast majority of neoplasms were represented by Grade 1 neuromas – in 57 (90 %) patients, Grade 1 neurofibromas were found in 3 (5 %) patients, and High-grade malignant tumors – in 3 (5 %). Intracanal neoplasms were found in 42 (66.7 %) cases and intraextravertebral (hourglass) – in 21 (33.3 %).Results. Microsurgical removal of tumor was performed using two types of low-traumatic surgical approaches: 1) posterior median approach – in 56 (89.0 %) cases, of which hemilaminectomy was performed in 36 (64.4%) cases, interlaminectomy – in 15 (26.8 %) cases, and laminectomy – in 5 (8.1 %) cases; 2) paravertebral approach – in 7 (11.0 %) out of 63 cases with partial facetotomy or facetectomy and resection of part of the head and upper or lower edge of the rib at the same level. Tumors were removed totally in 56 (88.9 %) patients and subtotally – in 7 (11.1%). Intracanal tumors were removed totally in 40 (95.2 %) patients. A similar totality was achieved in removal of 16 (76.2 %) of hourglass neurinomas. Surgical interventions performed in the early postoperative period improved the functional state of  patients: the Karnofsky Performance Scale (KPS) index increased from 70–80 to 90 %, the VAS pain score decreased from 5–6 to 2 points. Good clinical outcomes were achieved in 42 (66.7 %) patients, satisfactory – in 17 (27.0 %), and unsatisfactory – in 6 (6.3 %).
