Clinical Outcomes Of Brace Treatment Of Adloecent Idiopathic Scoliosis Using "The Form Of Guiding Bracing Treatment"

Background and ObjectiveIt is generally accepted that the progression of an idiopathic scoliotic deformity with a Cobb angle of between 20°and 40°stopped by brace treatment alone provided that the generally acknowledged criteria for the treatment concerning skeletal growth of the individual are respected. However, in the period of treatment, particularly the children have relatively low compliance of treatment, which can impact therapeutic effect obviously. Furthermore, there is a prodigious disjunction between our orthopedic doctors and orthopaedic technology, which can increase the blindness of using orthotic device and reduce therapeutic effect. According to the clinical needs and based on a large number of information, we found the mistakes frequently appeared when using the brace, than standardized and taken the shape of "The form of guiding bracing treatment "which can make the patients understand the using method of brace clearly.Methods1 Determinate standardized method of bracing treatment2 Develop"The form of guiding bracing treatment"3 Determinate orthopedic equipment4 Determinate screening standard5 Clinical material:a retrospective analysis of 68 AIS patients with apex vertebrae(AV) under T6 accepted the improved Cheneau brace produced by the same LTD between March 2008 and June 2010. Since Table 1 was designed and accomplished at September 2008, all patients were grouped by the beginning follow-up time as following: Intervention group have 51 cases (using Table 1, the beginning follow-up time after September 2008)and control group with 17cases(do not use Table 1, the beginning follow-up time before September 2008). In intervention group, mean age was 13.6 years(rang,10.6 years-17.2 years), mean Cobb angle was 29.5°(rang,20°-38°), Risser sign was 2-4°, Vertebralrotation degree was 0-2; In control group, mean age was 13.2 years(rang,10.8 years-16.8 years), mean Cobb angle was 28.7°(rang,20°-37°), Risser sign was 2-4, Vertebralrotation degree was 0-2. Mean follow-up period was 21.6 months(rang,9months-27months).6 The Cobb angle datas at before treatment as well as 6th month,12th month, and 18th month after treatment were organized, and than were denoted by x±s by SPSS 15.0, as well as the reliability and validity of Table 1. Because the datas were according with Repeated Measures Data, we established Mixed model by stata10.0 to analysis datas.Results1 Coefficient (a) and intraclass correlation coefficient of Table 1 were both over 0.60.2 Recovery and qualified rate of Table 1 were both 97.54%,and with good content validity, but the structural validity was ont clearly.3 65 cases were followed up for 18-27 months, however,1 case(female) was lost in control group and 2 cases(female) in intervention group. Mean follow-up period was 19.7 months(rang,9months-27months). Coefficient (a) and intraclass correlation coefficient of Table 1 were both over 0.60. Recovery and qualified rate of Table 1 were both 97.54%,and with good content validity. The mean cobb angle of two groups decreased gradually, from 28.71°to 25.76°in control group and from 29.47°to 21.59°in intervention group.4 cases in control group and 34 cases in intervention group had reduced value over 5°of Cobb angle at 18 months after treatment, and more, the different of Cobb angle had statistic significance(P<0.0001) between two group.Conclucions"The form of guiding bracing treatment "has good reliability and validity, and could guide bracing treatment of AIS more correctly and effectively.
