BackgroundBracing is used as a valid non-surgical treatment for adolescent idiopathic scoliosis (AIS) to avoid progression of the deformity and thereby surgery. The effect of bracing treatment on quality of life of patients with AIS has been a topic of interest in the international literature. The aim of this study was to evaluate the quality of life and patient satisfaction during bracing treatment for AIS of a pediatric hospital.Material and methodWe assessed a total of 43 non-consecutive female patients (mean age at questionnaire, 13 years and 1 month and 10 years and 8 months to 14 years and 5 months; mean period of usage of brace, 1 year and 7 months), with adolescent idiopathic scoliosis (AIS), older than 10 years of age until skeletal maturity, with a Risser sign less than 3 and scoliosis between 20 and 45°, treated with thoracolumbosacral orthosis (TLSO) for a period longer than 6 months, and without other comorbidities or previous surgeries, were evaluated. The patients were administered a previously validated to Spanish questionnaire on quality of life (Brace Questionnaire (BrQ); Grivas TB et al.). BrQ is a validated tool and is considered a disease-specific instrument; its score ranges from 20 to 100 points, and higher BrQ scores are associated with better quality of life.ResultsThe patients reported using the brace for a mean of 17.6 h daily and for a mean period of 1 year and 7 months at the time of the study. Overall, 72% of the study population reported to be in some way psychologically affected by the brace wearing, 56% felt their basic motor activities were affected, 54% felt socialization with their environment was affected, 46% considered their quality of life deteriorated due to pain, and 40% reported conflicts in the school environment.ConclusionPatients with AIS treated with bracing reported a negative impact (53.5% overall) on quality of life and treatment satisfaction in terms of psychological, motor, social, and school environment aspects. An interdisciplinary approach would be important for the integrated psychosocial care of these patients.

In adolescent idiopathic scoliosis (AIS) there has been a shift towards increasing the number of implants and pedicle screws, which has not been proven to improve cosmetic correction. To evaluate if increasing cost of instrumentation correlates with cosmetic correction using clinical photographs. 58 Lenke 1A and B cases from a multicenter AIS database with at least 3 months follow-up of clinical photographs were used for analysis. Cosmetic parameters on PA and forward bending photographs included angular measurements of trunk shift, shoulder balance, rib hump, and ratio measurements of waist line asymmetry. Pre-op and follow-up X-rays were measured for coronal and sagittal deformity parameters. Cost density was calculated by dividing the total cost of instrumentation by the number of vertebrae being fused. Linear regression and spearman's correlation were used to correlate cost density to X-ray and photo outcomes. Three independent observers verified radiographic and cosmetic parameters for inter/interobserver variability analysis. Average pre-op Cobb angle and instrumented correction were 54° (SD 12.5) and 59% (SD 25) respectively. The average number of vertebrae fused was 10 (SD 1.9). The total cost of spinal instrumentation ranged from $6,769 to $21,274 (Mean $12,662, SD $3,858). There was a weak positive and statistically significant correlation between Cobb angle correction and cost density (r = 0.33, p = 0.01), and no correlation between Cobb angle correction of the uninstrumented lumbar spine and cost density (r = 0.15, p = 0.26). There was no significant correlation between all sagittal X-ray measurements or any of the photo parameters and cost density. There was good to excellent inter/intraobserver variability of all photographic parameters based on the intraclass correlation coefficient (ICC 0.74-0.98). Our method used to measure cosmesis had good to excellent inter/intraobserver variability, and may be an effective tool to objectively assess cosmesis from photographs. Since increasing cost density only improves mildly the Cobb angle correction of the main thoracic curve and not the correction of the uninstrumented spine or any of the cosmetic parameters, one should consider the cost of increasing implant density in Lenke 1A and B curves. In the area of rationalization of health care expenses, this study demonstrates that increasing the number of implants does not improve any relevant cosmetic or radiographic outcomes.

We concluded that HV resection by posterior approach-only with instrumentation is a simple, secure, reliable, less invasive and well tolerated technique that can successfully resolve this kind of congenital scoliosis in children.
