Effectiveness of the FED Method in the Treatment of Idiopathic Scoliosis of Girls Aged 11–15 Years

(1) Background: The unknown etiology of idiopathic scoliosis and its three-dimensional nature make the cause-and-effect therapeutic management difficult. A tendency to progression of scoliosis and the failure of many methods of conservative treatment have prompted the search for new methods that would stop and correct deformations. One of them is the FED method, used in the conservative treatment of idiopathic scolioses, in which all scoliotic curves are corrected. The aim of this study was a comparative analysis of the effectiveness of idiopathic scoliosis treatment with the FED and FITS methods. (2) Methods: The study included 60 randomly selected girls, aged 11 to 15 years, treated with the FED and FITS methods. They were diagnosed with idiopathic scoliosis grade II according to Cobb and double-curve scoliosis type I and II according to King–Moe classification. The results of the therapy were assessed with the use of the Bunnell scoliometer. The examinations were performed before the start of the therapy—on the first day of the child’s stay—and 3 weeks after the therapy. The angle of trunk rotation and the sum of two rotations were assessed using a scoliometer. (3) Results: The performed statistical analysis demonstrated significant changes in the examined parameters in both therapeutic groups. (4) Conclusions: 1. The obtained results indicate that the FED therapy may prove to be an effective method of treating idiopathic scoliosis; however, it requires further research in a larger group of patients; 2. both methods significantly improved trunk rotation in primary and secondary scoliosis, but after using summing parameters (SDR parameter), the FED method appeared to be statistically more effective.

Computed Tomographic Semiotics of Apical Vertebrae in Patients with Idiopathic Scoliosis Aged from 14 to 18 years, Depending on the Magnitude of Spinal Deformity

Idiopathic scoliosis, as many authors think, being idiopathic in terms of not fully clear etiology of the disease, due to the most complicated long-term studies, has a certain theory of the pathogenesis of scoliosis, which includes the disharmony of the longitudinal growth of the spine and spinal cord and the formation of vertebral torsion. The application of various versions of modern vertebral instrumentation for 20 years made it possible to develop a differentiated approach to the choice of surgical intervention, taking into account the patient’s age and the peculiarities of the deformed spine. Nevertheless, the use of current diagnostic methods indicated that not all the details of the deformed vertebral structure have been studied, in particular the apical ones, that are usually more changed being at the apex of the deformity. The application of multislice computed tomography (MSCT) and current statistical methods made it possible to reveal the structural features of the apical vertebrae in the group of adolescent scoliosis (14–18 years old), that is important for increasing the effectiveness of preoperative planning and improving the results of idiopathic scoliosis treatment being one of the most difficult problems of the spine surgery.

Reduction of radiation exposure in scoliosis monitoring using flat detector and pulsed fluoroscopy technology

A new flat detector and pulsed fluoroscopy technology is available to further reduce radiation exposure in radiological monitoring during scoliosis treatment in children and adolescents. The aim of this study is to compare different settings of the system (opening area(OA) and image quality settings (IQS)) in order to find the optimal parameters with high image quality and the lowest possible radiation exposure. Therefore, we examined four cadaver spines (T1 to sacrum) with the flat detector technique using digital pulsed fluoroscopy and simulated the abdominal soft tissues. The images were merged and evaluated by three different investigators using an established scoring system. For comparison, we used digital radiography images of the cadaver spines. The values for the DAP increased from the small OA (33% ; 0.56 µGy·m²) to the maximum OA (100% ; 0.82 µGy·m²) by 45% (p = .003) and from the low image quality setting (0.57 µGy·m²) to the high setting (0.84 µGy·m²) by 48% (p = .028). Despite the low DAP, the setting 33% OA achieved the best point values for image quality, therefore this setting is clearly preferred. Using a digital fluoroscopy system allows a significant reduction of radiation exposure by a factor of 7.5 (3.88µGy·m² to 0.5µGy·m²) compared to slot- scanning x-ray (EOS). Due to this success, the flat detector and pulsed fluoroscopy technology can be an alternative to established methods such as X-ray and EOS in clinical use.

CONSERVATIVE IDIOPATHIC SCOLIOSIS TREATMENT WITH BRACE PRODUCED USING 3D TECHNOLOGY

ABSTRACT Objective To evaluate the immediate correction capacity of the Wood-Chêneau-Rigo brace (WCR), produced using digital technological resources and robotic engineering, in primary and secondary curves of adolescent idiopathic scoliosis (AIS). Methods A retrospective study was conducted of 138 patients with a diagnosis of AIS and who received a WCR brace from a laboratory that makes orthoses and orthopedic prostheses between 2019 and 2021. These individuals were submitted to an independent analysis of the radiographic parameters by a single researcher, the main outcome of which was the standardized measurement of the main and secondary curves using the Cobb method. The radiographs analyzed were performed in orthostasis before and immediately after the adaptation of the brace on the patient. The correction capacity was calculated as the ratio of the difference between the pre- and post-brace curves to the pre-brace curve. Results The mean correction with the WCR was 48.4% for the main curve and 41.0% for the secondary curve. The level of correction of the main curve was significantly higher in patients with a main curve with the apex of convexity in the thoracolumbar region (p = 0.004), especially in the left thoracolumbar region (p = 0.010); curves of magnitude between 10º and 24.9º (p <0.001); and curves classified as simple (p <0.001). Conclusion The use of the WCR, which is produced using modern technological resources, was effective in the immediate correction of AIS. Long-term studies on this new modality of conservative scoliosis treatment are necessary. Level of evidence III; Retrospective study.

The Clinical and Genotypic Spectrum of Scoliosis in Multiple Pterygium Syndrome: A Case Series on 12 Children

Background: Multiple pterygium syndrome (MPS) is a genetically heterogeneous rare form of arthrogryposis multiplex congenita characterized by joint contractures and webbing or pterygia, as well as distinctive facial features related to diminished fetal movement. It is divided into prenatally lethal (LMPS, MIM253290) and nonlethal (Escobar variant MPS, MIM 265000) types. Developmental spine deformities are common, may present early and progress rapidly, requiring regular fo llow-up and orthopedic management. Methods: Retrospective chart review and prospective data collection were conducted at three hospital centers. Molecular diagnosis was confirmed with whole exome or whole genome sequencing. Results: This case series describes the clinical features and scoliosis treatment on 12 patients from 11 unrelated families. A molecular diagnosis was confirmed in seven; two with MYH3 variants and five with CHRNG. Scoliosis was present in all but our youngest patient. The remaining 11 patients spanned the spectrum between mild (curve ≤ 25°) and malignant scoliosis (≥50° curve before 4 years of age); the two patients with MYH3 mutations presented with malignant scoliosis. Bracing and serial spine casting appear to be beneficial for a few years; non-fusion spinal instrumentation may be needed to modulate more severe curves during growth and spontaneous spine fusions may occur in those cases. Conclusions: Molecular diagnosis and careful monitoring of the spine is needed in children with MPS.

Scoliosis in Goldenhar syndrome with curve reversal during brace treatment: a case report

Background Goldenhar syndrome sometimes displays progressive scoliosis and other spinal deformities that require treatment. However, few reports exist on scoliosis correction in Goldenhar syndrome. We described the rare radiological outcomes of a patient with Goldenhar syndrome who received brace treatment for scoliosis. Case presentation A 4-year-old boy was diagnosed as having Goldenhar syndrome and referred to our hospital for scoliosis treatment. The deformity deteriorated gradually, and left convex scoliotic angle was 26 degrees (T3-L2) at 11 years of age. Unexpectedly during treatment with an orthopedic brace, the curve had reversed to 21 degrees (T5-L2) at 7 months of therapy. After another adjustment of the brace, his right convex scoliotic angle improved to 13 degrees (T4-L2) at 15 months of treatment. Conclusions Curve reversal may occur during brace treatment for scoliosis in Goldenhar syndrome. Clinicians may opt to periodically check curve correction despite the risk of increased radiation exposure.
