Purpose of the study — to evaluate the degree of correction of acetabular spatial position after triple pelvic osteotomy using patient-specific templates in children with dysplastic hip subluxation. Materials and methods. Study included 30 patients (30 hips) with dysplastic hip subluxation aging from 14 to 18 years (mean age of 16.3±1.4). All children were divided into two groups — main group consisted of 15 children (15 hips) who underwent triple pelvic osteotomy using patient-specific templates produced by 3D modeling and prototyping technology; control group consisted of 15 children (15 hips) who underwent triple pelvic osteotomy based on standard preoperative planning. X-ray and CT of hip joints was made in all patients. Results. Parameters of acetabular spatial position as well as integral parameters which define the ratio between acetabulum and femoral components and hip stability were in the range of normal variation in patients of the main group. Similar average parameters in patients of control group were below the lower margin of the physiological norm (p<0.05). Besides, the values of standard deviation of abovementioned X-ray parameters in some patients of control group demonstrated pronounced variability characterized by hyper- and hypo-correction values of spatial position of acetabular fragment. Conclusion. In contrast to standard preoperative planning the use of patient-specific templates during re-orienting triple pelvic osteotomy in children with dysplastic hip subluxation allows to level out possible errors in three-dimensional acetabulum positioning towards hyper- and hypo-correction (p<0.05) of pelvic component. This creates conditions to ensure adequate hip stability which is confirmed by key x-ray indices with values within normal reference range.

Objective. 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.

Objective. To assess sagittal balance parameters in children with spondylolisthesis before and after surgical treatment and to analyze their correlation with quality of life.Material and Methods. A retrospective analysis of postural radiographs of 98 children and adolescents was performed. The patients were divided into 2 groups: Group 1 included 43 patients under 17 years of age (mean age 12.0 ± 2.6 years) without spinal pathology, and Group 2 – 55 patients under 17 years of age (mean age 13.3 ± 2.5 years) with spondylolisthesis before and after surgical treatment. In patients of Group 1, the main spinopelvic parameters (PT, PI, SS, LL, PI-LL, TK) were calculated and studied. In patients of Group 2, parameters characterizing local lumbosacral kyphosis (SA, Dub-LSA, LSJA) were calculated and studied in addition to the main ones. The obtained results were compared with the conditional norm for children. The intensity of pain syndrome and quality of life were assessed using questionnaires and scales (Ped`s QL, ODI, VAS) before surgical treatment, at the time of discharge from the hospital, and after 3 months since surgery. Statistical data analysis was carried out using the statistical programming language and the R environment (version 3.6.1) in RStudio IDE (version 1.2.1335) with representation in the M ± SD format for normally distributed random variables and Me [Q1; Q3] for variables with abnormal distribution. Categorical indicators were presented as an absolute number and a percentage ratio. The null hypothesis in statistical tests was rejected at a significance level of p < 0.05Results. A decrease in the intensity of pain syndrome and an improvement in the quality of life were observed after surgical treatment in all cases. Statistical analysis of the relationship between parameters characterizing local lumbosacral kyphosis (Dub-LSA, SA, LSJA) and the results of using questionnaires and scales (Ped`s QL, ODI, VAS) showed a statistically significant positive correlation (r = 0.57; p = 0.004) of the LSJA score and pain intensity assessed before surgery, as well as a statistically significant negative correlation (r = -0.47; p = 0.004) of the LSJA score before surgery and the results of the PED`s QL questionnaire after surgery. In a comparison group analysis, it was found that after surgical treatment, there was a tendency towards normalization of sagittal parameters, though their complete recovery to normal values was not achieved. Local lumbosacral kyphosis was completely eliminated in all cases.Conclusion. Correction of the angle of lumbosacral kyphosis during surgical treatment of children with spondylolisthesis directly correlates with indicators characterizing the quality of life, which makes its elimination the main purpose of the operation. The degree of correction of the sagittal balance parameters (PT, SS, LL) has no significant impact on the quality of life, and their correction to the target calculated values is not required at an initially high PI value. In cases of decompensation of the sagittal and coronal balances of the trunk with low grades of spondylolisthesis, combined with impaired gait and anterior inclination of the torso (lumbar-femoral rigidity syndrome), the instrumental restoration of segmental lordosis at the level of L5–S1 and decompression of neural structures lead to correction of sagittal balance and normalization of gait.
