HGT is a safe technique as the world literature describes complications in the form of loosening of the pins or superficial infections of the skin around the pins, which are not significant and do not pose a threat to the patient’s life. Purpose – to improve the results of the ventilation function of the lungs in patients with complex spinal deformities through the preliminary use of halo gravity traction and to introduce an effective and safe method for the treatment of complex spinal deformities in children with respiratory dysfunctions. Materials and methods. 64 children with complex spinal deformities (>100°) were treated in the orthopedic and traumatology department of the Okhmatdet NSPU using halo gravity traction during the period from 2003 until 2018. Of these, 38 are boys and 26 are girls. The average age of the patients was 11.6 years. The average Risser score was 3.8 (P>0.01). Results. According to the data of spirography performed, 46% of patients had moderate ventilation disorders and 54% – severe ventilation disorders (FVC<60% – grade 3 and 4 of ventilation failure). Mixed type disorders were recorded in 83% of patients, and restrictive type disorders in 17% (8/48) of children. After HGT, there was an improvement in pulmonary function indicators: an increase in FVC from 63.19% to 71.77% and FEV1 from 54.71% to 65.46%, Tiffeneau-Pinelli index – from 74.59% to 85.33%. Compared with the initial level of indicators, the improvement in FVC was 13.6% after HGT and 14.6% in dynamics during the year, and FEV1 – 19.6% and 21.6%, respectively. The results obtained indicate a significant improvement in the ventilation function of the lungs, especially due to the degree of FEV1 increase, which correlates with the degree of improvement in performance, mortality and life prognosis. Conclusions. The use of HGT makes it possible to improve the results of the final correction of spinal deformity, which in turn significantly improves the ventilation function of the lungs, which in turn helps to reduce the risks of mortality due to pulmonary insufficiency in adulthood. The choice of the appropriate methods of surgical correction for complex deformity of the spine is a prerequisite for successful treatment and the achievement of three-dimensional correction of the spine to maximally approximate its parameters to the physiological norm. The indication for halo gravity traction is a rigid scoliotic deformity of the spine with a deformity angle (>100°). This study was conducted in accordance with the principles of the Helsinki Declaration. The research protocol was approved by the Local Ethics Committee of the institutions mentioned in the work. Informed parental agreement was obtained for the research. No conflict of interests was declared by the authors. Key words: spinal deformity, respiratory dysfunctions, halo-gravity traction.

ABSTRACT This study presents details about the applicability of the new image acquisition system, called the biplanar imaging system, with three-dimensional capabilities (EOS®) to the treatment of spinal deformities. This system allows radiographic acquisition of the entire body, with a great reduction in the dose of radiation absorbed by the patient and three-dimensional (3D) stereoradiographic image reconstruction of bone structures, including the spine. In the case of adolescent idiopathic scoliosis, the analysis of the spinal deformity with 3D reconstruction allows better understanding of the deformity and surgical planning. In the case of adult spinal deformity, full-body analysis allows an evaluation of the spinopelvic deformity, including loss of sagittal alignment, in addition to an evaluation of compensatory mechanisms recruited by the individual in an attempt to maintain the sagittal balance. Level of evidence III; Descriptive Review.

Study Design: Systematic review. Objectives: This current systematic review seeks to identify current applications and surgical outcomes for 3-dimensional printing (3DP) in the treatment of adult spinal deformity. Methods: A comprehensive search of publications was conducted through literature databases using relevant keywords. Inclusion criteria consisted of original studies, studies with patients with adult spinal deformities, and studies focusing on the feasibility and/or utility of 3DP technologies in the planning or treatment of scoliosis and other spinal deformities. Exclusion criteria included studies with patients without adult spinal deformity, animal subjects, pediatric patients, reviews, and editorials. Results: Studies evaluating the effect of 3DP drill guide templates found higher screw placement accuracy in the 3DP cohort (96.9%), compared with non-3DP cohorts (81.5%, P < .001). Operative duration was significant decreased in 3DP cases (378 patients, 258 minutes) relative to non-3DP cases (301 patients,272 minutes, P < .05). The average deformity correction rate was 72.5% in 3DP cases (245 patients). There was no significant difference in perioperative blood loss between 3DP (924.6 mL, 252 patients) and non-3DP cases (935.6 mL, 177 patients, P = .058). Conclusions: Three-dimensional printing is currently used for presurgical planning, patient and trainee communication and education, pre- and intraoperative guides, and screw drill guides in the treatment of scoliosis and other adult spinal deformities. In adult spinal deformity, the usage of 3DP guides is associated with increased screw accuracy and favorable deformity correction outcomes; however, average costs and production lead time are highly variable between studies.
