Deformation Correction

Objective. To define the most effective assemblies of external transpedicular fixator for correction of kyphotic and scoliotic deformities of the spine. Material and Methods. Treatment results in 108 adolescents with different kinds of III–IV degree scoliosis and kyphosis were studied. The spine deformation degree was assessed in accordance with V.D. Chaklin’ classification. Neurological examination have shown the absence of major neurological disorders. Deformation correction was performed with device consisting of transpedicular rods which were fixed to anchorage plates and coupled into support bases. Results. The application of the fixator with additional lateral traction is optimal to correct C-shaped scoliosis and the frame with damping device allows correcting the curvatures of S-shaped deformities within a short time, in some cases even hypercorrection can be achieved. The application of additional fixing rod is fruitful in kyphosis correction. Conclusion. The application of the external transpedicular fixator under radiological and clinical control allows the correction of various spine deformities without neurological deficit with the account of spine biomechanics.

The possibility of preservation and use of a resected rib for dorsal fusion at final correction of spinal deformity was studied. Treatment results for 80 patients aged 15 to 45 years, with severe spine deformity (scoliosis or kyphoscoliosis) were analyzed. In all patients two step surgical interventions was performed. Either transpedicular or hybrid (screws and sublaminar cerclage) fixation of the vertebral column were performed in 37 and 43 cases, respectively. After ventral release the resected ribs were stitched to subcutaneous fatty tissue and preserved until the time of final dorsal correction. The follow-up period made up 1 - 2 years. Fusion formation and autograft reconstruction was confirmed by radiologic methods. It was shown that rib auto preservation technique was a simple one, did not require special preservation conditions and allowed to preserve sufficient volume of autograft for final spinal deformity correction.

Treatment results for 24 patients (21 girls and 3 boys), aged 14—17 years, with idiopathic thoracic scoliosis are presented. In all cases right-side type of deformity was observed. The main arch of curvature ranged from 52° to 92° by Cobb. The operation was performed from dorsal approach with application of metallic devices with transpedicular supporting elements using 3D-CT navigation. Depending on anatomical and anthropometric peculiarities of vertebral bone structures within the curvature arch, two variants of surgical correction were applied. Correction of the first type was performed in 18 patients; second type of correction was applied in 6 children. Second type of deformity correction differed from the first one by the sequence of rods implantation relative to the sides of main arch and corrective maneuvers at deformity correction. In the first group postoperative deformity correction in frontal plane made up 92—99%, derotation correction of the apical vertebra from 72 to 94% versus 91—100% and from 11,4 to 29,4% in the second group.

Post Traumatic

Rigid severe post-traumatic thoracic spine deformities result from frequent, recent high-energy trauma in children with an increasing frequency due to a variety of reasons. These types of injuries are commonly followed by spinal cord anatomic injury; therefore, the treatment of these patients warrants special attention from the ethical viewpoint. Generally, the only indication for surgical intervention is spinal dysfunction. Considering this and the patients’ ordinary severe somatic state, surgical trauma should be minimized as much as possible. However, for adequate deformity correction, effective spine stabilization and restoration of liquorodynamics is necessary. Recent studies have reported the successful use of different methods of dorsal interventions (P/VCR) in cases with unstable damages in children. Here, we present the case of a 15-year-old boy who underwent surgical treatment for coarse post-traumatic thoracic spine deformity with chronic fracture-dislocation of Th7 vertebra.

Introduction. The spine deformities tend to increase, and in 90% of children they change the quality of life. The aim of this study was to determine the percents of spinal deformity in our population of adolescents, and long bad posture in and out of school as a factor for its increase. Material and methods. The study included 124 adolescents attending High Musical School in Bitola and Skopje, who underwent four standard spine tests and an interview. Results. According to the test 3, 50% of the examined adolescents in Bitola and 69% in Skopje had the postural spine deformity, the average being 59.5%. The results obtained by the questionnaire showed that 50% of adolescents did not have any physical activity out of school, the longest daily activity, lasting four hours, in 48% of the examinees was practising their musical instruments; 40% of the examinees spent two hours watching TV or using the computer, whereas 18% did not use any of them at all. Conclusion. The bad spine posture tends to deteriorate in adolescents and the factor influencing this result should be established by studies aimed at determining the effects of physical activity on reducing such deformities, since the specific type of their education induces the risk of developing pain and early degenerative changes of the spine, which are predominant in the professionals.

Temperature and Denaturing Substances Influence on Lab-on-a-Chip Electrophoresis Qualitative and quantitative determination of proteins in different biological fluids is of great significance in medicine, due to their importance in diagnosis and treatment of some diseases. Nowadays, different methods for protein analysis are available. Lab-on-a-chip electrophoresis is a relatively new technique, based on microfluidics, which allows samples of biological fluids to be analyzed within a microchip. This paper describes the optimization of performance of the chip-based protein analyses in serum samples from patients with different neurological disorders. Using microchip technology, serum proteins with the molecular mass from 4.5 to 240 Kb were separated and sized. The fluorescence detection method in the analysis was used to follow the influence of the temperature and the type and concentration of denaturing substances on the electrophoresis protein profiles. It was noted that, depending on incubation temperature and denaturing substances, different electrophoresis patterns can be obtained from the proteins of one specimen. Significant change of the fluorescence intensity was observed when different incubation temperatures were used, probably due to fluorescence quenching. In some cases, the band intensity was changed several times. Lab-on-a-chip electrophoresis is a very efficient method for the separation and determination of different serum proteins in a very short time. However, to obtain comparable results for the analysis, the denaturing agent concentration and temperature must be observed and maintained carefully.
