施罗斯PSSE联合3D打印支具治疗青少年特发性脊柱侧弯的疗效

Study on the efficacy of Schroth PSSE combined with 3D printing brace in the treatment of adolescent id⁃iopathic scoliosis

目的 评估施罗斯PSSE联合3D打印支具治疗青少年特发性脊柱侧弯的疗效。方法 纳入患者40例,分为支具组(3D打印支具组)与支具+运动疗法组(3D打印支具+施罗斯PSSE组),去除离群与失访数据,最终纳入32例患者,每组各16例。两组3D打印支具佩戴时间≥18 h。施罗斯PSSE干预周期为12周,12周后维持锻炼直至随访结束。支具组最长随访时间25个月,平均(15.00±1.29)月,支具+运动疗法组最长随访时间24个月,平均(16.59±1.01)月,随访结束后评价相关指标。结果 支具+运动疗法组主弯Cobb角、躯干旋转角(ATR)改善优于支具组,差异有统计学意义(P <0.05);支具+运动疗法组C7椎体中点—骶骨中垂线距离(C7-CSVL)治疗前后差异有统计学意义(P <0.05),顶椎偏距(AVT)治疗前后差异有统计学意义(P <0.01),两指标与支具组相比差异无统计学意义(P> 0.05);在SRS-22评分方面,支具+运动疗法组可全面提高SRS-22评分。结论 施罗斯PSSE联合3D打印支具相较单独使用3D打印支具对于主弯Cobb角与躯干旋转角改善效果更佳、对于冠状面失衡改善更好、患者满意度更高、改善生活质量更好。

Objective To evaluate the efficacy of Schroth PSSE combined with 3D printing braces in the treatment of adolescent idiopathic scoliosis.Method Forty patients were included and divided into a support group(3D printing support group)and a support+exercise therapy group(3D printing support+Schroth PSSE group).Excluding outliers and lost follow-up data,32 patients were ultimately included,with 16 patients in each group.Wearing time≥18 h for both groups of 3D printing supports.The intervention period of Schroth PSSE is 12 weeks,and exercise is maintained after 12 weeks until the end of follow-up.The longest follow-up time for the brace group was 25 months,with an average follow-up time of(15.00±1.29)months.The longest follow-up time for the brace+exercise therapy group was 24 months,with an average follow-up time of(16.59±1.01)months.Relevant indicators were evaluated after follow-up.Results The support and exercise therapy group showed better improvement in Cobb angle and trunk rotation angle(ATR)than the support group,with statistically significant differences(P<0.05);The distance between the midpoint of the C7 vertebral body and the midline of the sacrum(C7-CSVL)in the support and exercise therapy group showed a statistically significant difference before and after treatment(P<0.05),while there was a significant difference before and after Apical Vertebral Translation(AVT)treatment(P<0.01).There was no statistically significant difference compared to the support group(P<0.05);In terms of SRS-22 score,the brace+exercise therapy group can comprehensively improve the SRS-22 score.Conclusion The combination of Schroth PSSE and 3D printing braces has a better effect on improving Cobb angle and torso rotation angle,improving coronary imbalance,increasing patient satisfaction,and improving quality of life compared to using 3D printing braces alone.
