Self-perceived Health Status and Healthcare Consumption of Idiopathic Scoliosis Patients Treated More Than 20 Years Ago: How Much do Operated and Non-operated Patients Differ?

Study Overview
=================
Brief Summary
-----------------
Adolescent idiopathic scoliosis (AIS) is a common condition that affects millions of patients worldwide. This is characterized by a spinal deformity that leads to a deformation of the trunk, an imbalance of the shoulders and waist folds as well as the appearance of gibbosity. Posterior arthrodesis correction is a common practice surgery for the treatment of AIS after failure of medical treatment with a corset or functional rehabilitation. Surgery allows functional improvement and is indicated for curves greater than medically treated scoliosis. The objective of this international study is to have a better understanding of the long-term outcomes (> 20 years of follow-up) after treatment (surgical and non-surgical) of AIS and to compare the long-term status of the patient with AIS to the general population of the same age, sex and comorbidities. All of this information will help justify or modify the strategy, techniques and goals of early treatment in adolescence to achieve a better long-term outcome.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Long-term quality of life | Evaluate from the specific questionnaire for vertebral deformities: Scoliosis Research Society revisited(SRS-22r) (scale 0-5) with 5 sub-domains,higher scores representing greater patient quality of life. | 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The long-term quality of life | Assess the long-term quality of life (> 20 years), health status, and social and demographic outcomes of adult patients who underwent treatment (surgical and non-surgical) for idiopathic scoliosis during adolescence by the questionnaire EQ-5D-5L (100 is the best health you can imagine. 0 is the worst health you can imagine) | 1 day |
