TL;DR: There was a fivefold proportion of failures among patients with scoliosis> 30° at the start of therapy but no difference in progression between different kinds of nonsurgical therapies or between treated and untreated patients; these were the main findings of this quantitative analysis.
Abstract: To define further the effectiveness of nonsurgical therapy for idiopathic scoliosis, predefined criteria were established for selection and data retrieval from studies of therapy and natural history, and the results were synthesized quantitatively. Only studies of patients with no more than a 50 degree Cobb angle scoliosis were considered. Twenty-four reports were eligible. There was a fivefold proportion of failures among patients with scoliosis greater than 30 degrees at the start of therapy but no difference in progression between different kinds of nonsurgical therapies or between treated and untreated patients; these were the main findings of this quantitative analysis. These data cannot be used to prove the effectiveness or ineffectiveness of nonsurgical therapy for idiopathic scoliosis, and experimental controlled studies of different therapies seem to be justified both on ethical and scientific grounds. The findings of this overview can be used for their planning.

TL;DR: It is demonstrated unequivocally that the detection of hereditary orthodontic anomalies in young children allows the identification of a group of children who have a high risk of developing scoliosis in later years.
Abstract: Our study of 202 patients aged from 7 to 17 years treated for idiopathic scoliosis, and with a Cobb angle from 20° to 50°, showed a higher frequency of hereditary orthodontic anomalies than those in the control group. There was unmistakable evidence that acquired orthodontic anomalies occurred in both groups at the same rate of frequency. Our study demonstrated unequivocally that the detection of hereditary orthodontic anomalies in young children allows the identification of a group of children who have a high risk of developing scoliosis in later years.

TL;DR: The change in back shape after Luque segmental sublam-inar instrumentation was assessed in the frontal, sagittal, and transverse planes in 61 patients with adolescent idiopathic scoliosis using the Integrated Shape Investigation System and standard radiographic techniques.
Abstract: The change in back shape after Luque segmental sublaminar instrumentation was assessed in the frontal, sagittal, and transverse planes in 61 patients with adolescent idiopathic scoliosis using the Integrated Shape Investigation System (ISIS) and standard radiographic techniques. Luque instrumentation was found to be an effective method of correcting thoracic and thoracolumbar curves in the frontal plane with a 59% and 63% respective reduction in the size of the preoperative Cobb angle. Despite the frontal plane correction, however, the ISIS scan showed that of the 40 single thoracic curves, the rib hump was reduced in only 6 patients, was unchanged in 27 patients, and was worsened slightly in 7 patients. By contrast, thoracolumbar and lumbar curves were corrected in all three planes with a significant cosmetic improvement.
