Since 2013, an elongation bending derotation brace (EBDB) has been developed and applied to EOS in our institution. The goals of the study were 1) to compare radiographic changes before the use of EBDB (Pre-B), in brace (IB), and after the use of EBDB (Post-B) in a minimal two year follow-up; 2) to determine the compliance with the EBDB. Thirteen children diagnosed with an infantile scoliosis (IS) were retrospectively recruited. Under general anesthesia in the OR, child was placed on a Spica casting table, and the spine was manipulated by stockinet straps. Then 3D child's torso was scanned, the EBDB was designed and manufactured for exact fitting to the torso in the corrected position using CAD/CAM technology.1 Mean age at start of EBDB was 2 years and 6 months. Average follow-up was 36 months. Compliance showed a mean 19 hours per day (14 to 23 hours). Pre-treatment Cobb angle was 40°, in brace 22°, and out of brace 28° (p0.05). A cascade of EBDB effectively corrects and stabilizes the 3D spinal deformities in infantile. Thus the EBDB is considered as a successful modality in the treatment of IS children.The study aimed to determine the impact of 6-month rigid brace on back muscle strength and endurance in adolescents with idiopathic scoliosis. Sixty-one girls, aged 7.0-16.0, were analyzed in two groups the study group (6-month rigid brace wear) vs. the control group (no brace treatment), recruited consecutively and matched for age, body height, weight, BMI, primary curve location and Cobb angle. All patients underwent clinical and radiological examination, modified Biering-Sorensen test, prone and standing maximum strength and endurance tests. No significant difference between groups in back muscles strength or endurance, both gobal and reported to body weight was found. No relation between the daily brace time and the back muscle strength or endurance was observed. The 6-month use of a rigid brace did not affect the strength or endurance of the back muscles in adolescent girls treated for idiopathic scoliosis.For the brace treatment of adolescent idiopathic scoliosis (AIS), in-brace correction and brace-wear compliance are well-documented parameters associated with a greater chance of treatment success. However, the number of studies on the impact of sagittal and transverse correction on curve evolution in the context of bracing is limited. The objective of this work was to evaluate how immediate inbrace correction in the three anatomical planes is related to long-term curve evolution after two years of bracing. We performed a retrospective analysis on 94 AIS patients followed for a minimum of two years. We analyzed correlations between in-brace correction and two-year out-of-brace evolution for Cobb and apical axial rotations (ARs) in the medial thoracic and thoraco-lumbar/lumbar regions (MT & TL/L). We also studied the association between the braces' kyphosing and lordosing effect and the evolution of thoracic kyphosis (TK) and lumbar lordosis (LL) after two years. Finally, we separated the patients into three groups based on their curve progression results after two years (corrected, stable and progressed) and compared the 3D in-brace corrections and compliance for each group. Coefficients were statistically significant for all correlations. They were weak for Cobb angles (MT -0.242; TL/L -0.275), low for ARs (MT -0.423; TL/L -0.417) and moderate for sagittal curves (TK 0.549; LL 0.482). In-brace coronal correction was significantly higher in corrected vs stable patients (p=0.004) while compliance was significantly higher in stable vs progressed patients (p=0.026). This study highlights the importance of initial in-brace correction in all three planes for successful treatment outcomes.Early-onset scoliosis (EOS) can be a progressive and debilitating condition if left untreated. Different casting techniques have fallen in and out of favor over the years for conservative management. Two types of casting, elongation-derotation-flexion (EDF) and body casting (BC) are employed at our institution. Here we compare the radiographic outcomes between these two types of casting in a cohort of patients diagnosed with EOS. Sixteen children with EOS were treated by EDF serial casting while seventeen children with the same diagnosis were treated by BC. Radiographic measurements included Cobb angle, rib-vertebral-angle difference (RVAD) and vertebral rotation (VR) by Nash-Moe method in casting (IC) or out of casting (OOC), thoracic height (TH) and width (TW). All of the patients had x-ray measurements at pre-casting OOC, 1st IC and final post-casting OOC. Casts were changed every 2-4 months. Independent two sample t-test, Wilcoxon rank-sum test, and Chi-square test were performed. There were no significant differences at the initial treatment for age, classification of EOS, OOC, RVAD, VR, kyphosis, TH, and TW between EDF and BC casting. There were no significant differences of changes for OOC, RVAD, VR, kyphosis, TH and TW from pre-casting to the final post-casting status between two casting techniques (P>0.05). However, children with EDF tended to receive 3 to 4 more castings than those with BC (7.5 vs.4 casts) (P=0.007) and achieved better outcomes in success (25% vs.20%) and improvement (50% vs.10%) (P=0.03). EDF has better outcomes with EOS improvement when there is treatment of longer duration.The objective was to assess deformity correction and bone-screw force associated respectively with concave manipulation first, convex manipulation first, and different differential rod contouring configurations. Etomoxir order Instrumentation scenarios were computationally simulated for 10 AIS cases with mean thoracic Cobb angle (MT) of 54±8°, apical vertebral rotation (AVR) of 19±2° and thoracic kyphosis of 21±9°. Instrumentations with major correction maneuvers using the concave side rod were first simulated; instrumentations with major correction maneuvers using the convex side rod were then simulated. Simulated correction maneuvers were concave/convex rod translation followed by apical vertebral derotation and then convex/concave rod translation. There were no significant differences in deformity corrections and bone-screw forces between concave rod translation first and convex rod translation first with differential rod contouring. Increasing differential rod contouring angle and concave rod diameter improved AVR correction and increased the TK and bone-screw forces; the effect on the MT Cobb angle was not clinically significant.
