Bracing for idiopathic scoliosis has been a topic of great interest to both physicians and parents of children with the condition. Is bracing really effective and can it stop the natural progression of idiopathic scoliosis and thus prevent the child from possibly needing surgery? This is a question that medical researchers are trying to answer, and parents of children with scoliosis are eagerly awaiting the answer. However, answering this question requires extremely objective and unbiased clinical research data. The results of clinical research on bracing for children with idiopathic scoliosis have been inconclusive due to the complexity of the types of scoliosis, the significant differences in scoliosis angles, the many types of braces, and the differences in compliance with treatment. Although the majority of current clinical opinion is that bracing is effective for specific children with scoliosis, there is considerable clinical research that questions this opinion. A recent breakthrough in clinical research on bracing for idiopathic scoliosis was published in 2013 by Professor Weinstein in the New England Journal of Medicine. The study, led by Professor Weinstein of the University of Iowa Orthopaedic Surgery, an internationally renowned expert in scoliosis, was a multi-center study funded by the National Institutes of Health and involving 26 medical centers in the United States and Canada. A total of 242 children with scoliosis were enrolled in the study, and the criteria for brace treatment were: age 10-15 years, skeletal immaturity (Risser’s sign of 0, 1 or 2), and scoliosis angle of 20 to 40 degrees. The study compared the differences in clinical treatment effectiveness between brace treatment and conservative observation. The criterion for treatment effectiveness was that the child had no progression of scoliosis at skeletal maturity, whereas treatment failure was when the patient had progression of scoliosis to 50 degrees or more. In a randomly assigned group of children, the effectiveness of brace treatment was 75% compared to 42% for conservative observation, and the effectiveness of brace treatment was positively correlated with the amount of time the child wore the brace each day. The study was initiated in 2007, but was terminated early due to the finding of clear effectiveness of bracing. The final conclusion stated that bracing reduces the chance of surgery for children at high risk for scoliosis progression. At the same time, this benefit increased with the amount of time the child wore the brace each day. From this study, it is clear that brace therapy is recommended for children at high risk for idiopathic scoliosis. However, for children with relatively mature scoliosis or other types of scoliosis, it should be said that there is no clear evidence that brace therapy is effective. One aspect that should not be overlooked is the negative impact on the psychological development of children who wear braces for more than 23 hours per day during adolescent development. Therefore, we do not recommend to blindly expand the indications for brace therapy, but rather to make a reasonable choice by the doctor, parents and even the child himself, taking into account the actual situation of each child.
