“…This study population was the same as that in the study of Sanders, et al1 in which a cohort of 22 girls with AIS was followed through their growth spurt with serial PA spine radiographs, serial skeletal age radiographs, and a number of clinical and biochemical markers of maturation obtained every six months. Patients were braced according to accepted criteria and instructed to wear the brace 23 hours per day.…”

“…The total Cobb angle for a major curve was the sum of the disc wedge angles and vertebral wedge angles for the levels of that curve. For each patient the total Cobb angle, total disc wedge angle and total vertebral wedge angle were graphed against the digital skeletal age (DSA) 1. The time axis of these graphs was divided into three phases corresponding to the three main stages of growth: pre-curve acceleration phase, curve acceleration phase (CAP), and post-curve acceleration phase.…”

“…Part of this is because reliable comparison of patients at the same stage of curve progression has been impossible. The high correlation of the digital skeletal age (DSA) with the curve acceleration phase (CAP) in adolescent idiopathic scoliosis provides an opportunity to make appropriate comparisons between patients 1. Although both discs and vertebrae deform in progressive scoliosis, the relative contribution of each to Cobb angle progression has not been demonstrated.…”

Study Design-Longitudinal radiographic study of patients with progressive idiopathic scoliosis.Objective-To determine the relative contributions of vertebral and disc wedging to the increase in Cobb angle during 3 phases of adolescent skeletal growth and maturation.Summary of Background Data-Both disc wedging and vertebral body wedging are found in progressive scoliosis, but their relative contribution to curve progression over time is unknown. Which occurs first is important for understanding how scoliosis progresses and for developing methods to halt progression. Previous studies have not properly identified maturity and provide conflicting results.Methods-Eighteen girls were followed through their adolescent growth spurt with serial spine and hand skeletal age radiographs. Each Cobb angle was divided into disc wedge angles and vertebral wedge angles. The corresponding hand radiographs provided a measure of maturity level, the Digital Skeletal Age (DSA). The disc versus bone contributions to the Cobb angle were then compared during 3 growth phases: prior to the growth spurt, during the growth spurt and after the growth spurt. Significance of relative changes was assessed with the Wilcoxon two-sided mean rank test.Results-Prior to the growth spurt, there was no difference in relative contributions of the disc and the bone (3° vs 0°, p=0.38) to curve progression. During the growth spurt, the mean disc component progressed significantly more than that of the vertebrae (15° vs 0°, p=0.0002). This reversed following the growth spurt with the vertebral component progressing more than the disc (10° vs 0°, p=0.01).Conclusion-Adolescent idiopathic scoliosis initially increases through disc wedging during the rapid growth spurt with progressive vertebral wedging occurring later.

“…The two above-mentioned systems to determine skeletal age (Greulich and Pyle atlas and the Tanner-Whitehouse RUS scoring systems) would then be recommended. In a quite recent study Sanders et al (2007) found that the TW-III RUS scoring system is the most reliable and accurate method to mark the initiation of the acceleration phase of growth. In this last study Sanders et al (2007) noted that the skeletal maturation score derived with the use of the TW-III RUS method was not only the best to mark the period of the curve acceleration phase but also separated patterns into low, moderate, and rapid curve acceleration.…”

Progressive adolescent idiopathic scoliosis (AIS) produces specific signs and symptoms, including trunk and spinal deformity and imbalance, impairment of breathing function, pain, progression during adult life, and psychological problems, as a whole resulting in an alteration of the health-related quality of life. A scoliosis-specific rehabilitation program attempts to prevent, improve, or minimize these signs and symptoms by using exercises and braces as the main tools in the rehabilitation treatment. Patient evaluation is an essential point in the decision-making process and determines the selection of the specific exercises and the specifications of the brace design. However, this article is not addressed to scoliosis management. In this present article, a complete definition and discussion of radiological aspects, such as the Cobb angle, axial rotation, curve pattern classifications, and sagittal configuration, follow a short description of the three-dimensional nature of AIS. The relationship between AIS and growth is also discussed. There is also a section dedicated to the assessment of trunk deformity and back asymmetry. Other important clinical aspects, such as pain and disability, changes in other regions of the body, muscular balance, breathing function, and health-related quality of life, are not discussed in this present article.
