However, in clinical practice surgeons could encounter a series of patients who utterly refused surgery and insisted on wearing brace despite having a curve >40 degrees.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n A cohort of 54 patients with Cobb angle between 40 and 50 degrees were reviewed in the current study. All the patients refused surgery at their first visit and insisted on receiving brace treatment. Each patient was followed up at an interval of 3\u20136 months. Variants such as initial Risser sign, initial age, sex, curve pattern, and initial curve magnitude were compared between patients with and without curve progression. A logistic regression analysis was performed to determine the independent predictors of the curve progression.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n On the whole, the curve progressed in 35 patients, remained stable in 12 patients, and improved in the else 7 patients. All the patients with curve progression finally received surgical intervention. The mean grade of initial Risser sign in patients with curve progression was significantly lower than that in patients with stable or improved curve (0.3\u00b10.8 vs. 1.2\u00b11.4, P<\/jats:italic>=0.02). In terms of sex, age, curve pattern, and curve magnitude, there were no significant differences between the 2 categories. The results of the logistic regression analysis showed that initial Risser sign of grade 0 or 1 had significant associations with the curve progression of patients with curves >40 degrees (odds ratio, 7.51, 95% confidence intervak, 1.27\u201324.43, P<\/jats:italic>=0.02).<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n The effectiveness of brace treatment significantly decreases when applied to patients with curve magnitude between 40 and 50 degrees. Although a majority of these patients will inevitably undergo a surgical intervention, and thus wearing a brace may not be the best alternative to surgical intervention; there are patients who will stabilize with the brace until skeletal maturity thus warranting this option for those patients refusing surgical intervention with curves between 40 and 50 degrees.<\/jats:p>\n <\/jats:sec>","DOI":"10.1097\/bsd.0b013e3182a1de29","type":"journal-article","created":{"date-parts":[[2014,2,5]],"date-time":"2014-02-05T17:12:08Z","timestamp":1391620328000},"page":"85-89","source":"Crossref","is-referenced-by-count":18,"title":["Is Brace Treatment Appropriate for Adolescent Idiopathic Scoliosis Patients Refusing Surgery With Cobb Angle Between 40 and 50 Degrees"],"prefix":"10.1097","volume":"30","author":[{"given":"Zezhang","family":"Zhu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leilei","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Long","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Qiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bang-Ping","family":"Qian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saihu","family":"Mao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Qiu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20230831","first-page":"115","article-title":"Adolescent idiopathic scoliosis: prevalence and natural history","volume":"38","author":"Weinstein","year":"1989","journal-title":"Instr Course Lect"},{"key":"R2-20230831","first-page":"529","article-title":"Adolescent idiopathic scoliosis: etiology, anatomy, natural history, and bracing","volume":"54","author":"Parent","year":"2005","journal-title":"Instr Course Lect"},{"key":"R3-20230831","doi-asserted-by":"crossref","first-page":"632","DOI":"10.1097\/00007632-198409000-00015","article-title":"Effectiveness of braces in mild idiopathic scoliosis","volume":"9","author":"Miller","year":"1984","journal-title":"Spine (Phila Pa 1976)"},{"key":"R4-20230831","doi-asserted-by":"crossref","first-page":"636","DOI":"10.1097\/00007632-198906000-00018","article-title":"The biomechanical effectiveness of the Boston brace in the management of adolescent idiopathic scoliosis","volume":"14","author":"Chase","year":"1989","journal-title":"Spine (Phila Pa 1976)"},{"key":"R5-20230831","doi-asserted-by":"crossref","first-page":"902","DOI":"10.1097\/00007632-199306000-00015","article-title":"A statistical comparison between natural history of idiopathic scoliosis and brace treatment in skeletally immature adolescent girls","volume":"18","author":"Goldberg","year":"1993","journal-title":"Spine (Phila Pa 1976)"},{"key":"R6-20230831","doi-asserted-by":"crossref","first-page":"815","DOI":"10.2106\/00004623-199506000-00001","article-title":"Effectiveness of treatment with a brace in girls who have adolescent idiopathic scoliosis.
