背景:脊柱侧凸的术前灵活性是手术计划的关键方面,因为它提供了曲线刚度的信息,结构变化的程度,要融合的水平和校正量。这项研究的目的是通过确定这两个特征之间的相关性来评估仰卧灵活性是否可用于预测青少年特发性脊柱侧凸(AIS)患者的术后矫正。
方法:对2018年至2020年间接受手术治疗的41例AIS患者进行回顾性分析。收集术前,术后站立X线片和整个脊柱的术前CT图像,并用于测量仰卧柔韧性和术后矫正率。采用T检验分析两组仰卧灵活性和术后矫正率的差异。进行了皮尔逊积矩相关分析,并建立回归模型来确定仰卧位灵活性与术后矫正之间的相关性。独立分析胸曲线和腰曲线。
结果:发现仰卧柔韧性明显低于矫正率,但与术后矫正率具有很强的相关性,胸曲组r值为0.68,腰曲组r值为0.76。仰卧位灵活性与术后矫正率之间的关系可用线性回归模型表示。
结论:仰卧位灵活性可用于预测AIS患者术后矫正。在临床实践中,仰卧射线照片可以用来代替现有的灵活性测试技术。
BACKGROUND: The preoperative flexibility of the scoliotic spine is a key aspect of surgical planning, as it provides information on the rigidity of the curve, the extent of structural changes, the levels to be fused and the amount of correction. The purpose of this study was to assess whether supine flexibility can be used to predict postoperative correction in patients with adolescent idiopathic scoliosis (AIS) by determining the correlation between these two characteristics.
METHODS: A total of 41 AIS patients who underwent surgical treatment between 2018 and 2020 were retrospectively enrolled for analysis. Preoperative and postoperative standing radiographs and preoperative CT images of the entire spine were collected and used to measure supine flexibility and the postoperative correction rate. T tests were used to analyse the differences in supine flexibility and postoperative correction rate between groups. Pearson\'s product-moment correlation analysis was performed, and regression models were established to determine the correlation between supine flexibility and postoperative correction. Thoracic curves and lumbar curves were analysed independently.
RESULTS: Supine flexibility was found to be significantly lower than the correction rate but showed a strong correlation with the postoperative correction rate, with r values of 0.68 for the thoracic curve group and 0.76 for the lumbar curve group. The relationship between supine flexibility and postoperative correction rate could be expressed by linear regression models.
CONCLUSIONS: Supine flexibility can be used to predict postoperative correction in AIS patients. In clinical practice, supine radiographs may be used in place of existing flexibility test techniques.
