The objective of this systematic review was to analyze the clinical efficacy of various technical options for surgical treatment of patients with injuries to the lower thoracic and lumbar spine. The review includes 57 studies published in 2001–2022, which were selected from the main medical databases – PubMed, Medline, and The Cochrane Database of Systematic Reviews. In these publications, five options for surgical intervention were identified, the clinical effectiveness of which was determined by the degree of regression of neurological disorders, the quality of the achieved reposition, the amount of loss of correction within two years after surgery, the number of complications, the duration of operations, and the amount of blood loss. For pairwise comparison between groups, the Kruskal – Wallis test was used for several independent samples, based on the initial determination of the normality of data distribution in groups. To determine the differences between the parameters before and after the operation, the Wilcoxon test was used for two dependent samples. Differences were considered statistically significant at p < 0.05. An analysis of the literature data showed that there are no differences in the dynamics of neurological recovery in patients with spinal cord injury in the thoracic or lower lumbar spine when using five different types of surgical treatment. There are also no differences in the quality of correction of kyphotic deformity of injured spinal motion segments between all studied groups. Statistically significant lower loss of deformity correction is noted in patients who underwent one-stage circumferential decompression through posterolateral approach and decompression through combined approaches. Notably, operations performed through isolated posterior or anterior approaches have comparable values of correction loss. Operations with decompression of the dural sac through the posterior approaches are characterized by a significantly shorter time of surgical intervention than operations with decompression through the anterior and combined approaches. The smallest volume of blood loss is observed during surgery with decompression through isolated posterior approaches. The largest volume of blood loss is in the group with posterolateral approach and one-stage circumferential decompression. Surgical interventions through posterior approach have a statistically significant lower complication rate than operations that include the anterior stage.
Objective of the review was to identify, basing on literature data, the most reliable X-ray and CT signs of damage to the posterior ligamentous complex (PLC) in fractures of the vertebral bodies of the thoracolumbar junction, initially interpreted as type A according to the AOSpine classification. The systematic review was carried out according to the recommendations of PRISMA. The search in PubMed, MEDLINE and Cochrane Library databases revealed 491 articles on relevant issues. Once the inclusion and exclusion criteria have been met, 7 original articles from peer-reviewed scientific journals for the last 10 years were selected for a systematic review, 6 of which were included in the meta-analysis. In all articles, the authors identified two groups of patients: with and without damage to the PLC. The PLC damages were confirmed by MRI and intraoperatively. Radiographic and CT spondylometric parameters were identified, which had statistically significant differences between the groups. To determine predictors of PLC damage, the values of these parameters were subjected to regression analysis. This was followed by a meta-analysis of random and fixed effects models depending on the homogeneity of the data. Statistical heterogeneity was assessed using the X-square test with the null hypothesis of the absence of significant differences in all studies, as well as the heterogeneity index – I2. For the graphical display of the results, forest plots were built. Local kyphosis angle >25°, Cobb angle >16° and difference between interspinous distances >2.54 mm are CT scan predictors of PLC damage. The parameters characterizing the interspinous relationship were studied in no more than two studies, but at the same time they always had statistically significant differences between the groups with and without PLC injuries, therefore, they cannot be ignored during diagnosis. Anterior/posterior vertebral height ratio, anterior vertebral height ratio, sagittal index and suprajacent/subjacent parameters are not the predictors of PLC damage.
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.
