The construction methods of the same brace vary on an experiential basis according to who builds them, the prescriber, the characteristics of the patients and also the innovations introduced to ensure greater comfort for the patient. The closure of the brace or the way in which the two shells are fixed varies at the discretion of the orthopedic technician. Plastic materials have also changed. In addition, the use of the classic cast for the production of the negative model was gradually replaced by cad-cam technology. In some cases, modular constructions were introduced with respect to the customized one. All this has changed the classic corsets over time, even without changing their name / type, and according to the hypothesis that their effectiveness remained at least the same, if not even improved.
There are no publications that have shown variations in efficacy that can be correlated with some of these stylistic variations.
The purpose of this study is to retrospectively investigate whether the various innovations and stylistic variations over time have had an effect on the clinical, functional and radiographic outcomes in growing subjects suffering from spinal deformity treated with corsets at a specialized center.

| HRQOL | measures of quality of life. The Italian Spine Youth Quality of Life questionnaire (ISYQOL) measures the health-related quality of life of adolescents with spinal deformities. ISYQOL consists of 20 items, each scored 0, 1 or 2. In accordance with the Rasch analysis technique, used to develop the questionnaire, the ordinal ISYQOL total score is converted to an interval measure (i.e., ISYQOL measure), which is expressed on a 0%-100% scale (with 100% indicating high quality of life). |

| HRQOL | measures of quality of life. The Scoliosis Research Society-22 (SRS-22) is a questionnaire developped to measure health-related quality of life in patients with idiopathic scoliosis. It has 22 questions divided into five domains: function/activity, pain, self-image/appearance, mental health and satisfaction with management. Each domain contains five questions, except the satisfaction with management domain, which contains two questions. Each item can be scored from 1 (worst possible) to 5 (best possible). The function/activity, pain, self-image and mental health domains have a total score ranging from 5 to 25. The satisfaction with management domain has a total score ranging from 2 to 10. The maximum total score is 110 and the results are expressed as a mean | pre-treatment, after a month from the start of brace wearing, after 5 ± 2 months, after an average period of 4 years +/-2 , and 1 year later |
| Treatment outcome | variation of the main curve of at least 5 Cobb degrees, end treatment results: main curve </=30 Cobb degrees, main curve </=45 Cobb degrees, and main curve >50 Cobb degrees | after an average period of 4 years +/-2 |
| Treatment compliance | Treatment compliance measures: percentage of brace wearing declared and measured by heat sensors | after a month from the start of brace wearing, after 5 ± 2 months, and after an average period of 4 years +/-2 |
| Deformity clinical measures | score on the evaluation of the aesthetic profile of the trunk (TRACE) | pre-treatment, after a month from the start of brace wearing, after 5 ± 2 months,after an average period of 4 years +/-2 , and 1 year later |
| Deformity clinical measures | measurement of the hump on the Adams test in degrees | pre-treatment, after a month from the start of brace wearing, after 5 ± 2 months,after an average period of 4 years +/-2 , and 1 year later |
| Deformity clinical measures | measurement of the hump on the Adams test in millimeters | pre-treatment, after a month from the start of brace wearing, after 5 ± 2 months,after an average period of 4 years +/-2 , and 1 year later |
