The aim of the study was to investigate the relationship between the interpedicular distance increase ratio and the ratio of canal compromise in thoracolumbar burst fractures.
Thirty-one patients (18 male and 13 female) with an average age of 30.8 (14-57) who had been treated for thoraco-lumbar burst fractures in the Department of Orthopaedics and Traumatology were included in the study. The initial anteroposterior radiographs of the patients were used to calculate the increase ratio of interpedicular distance (both from medial-to-medial and from center-to-center). The area measurements from the computerized tomography or magnetic resonans images were used to calculate the canal compromise. The relationship between the increase ratio of interpedicular distance and the ratio of canal compromise was investigated by correlation and linear regression analysis.
There was a 'very good' correlation between the from medial-to-medial and from center-to-center measurements of interpedicular distance (Pearson correlation coefficient: 0.89, p<0.001). The correlation between the ratio of canal compromise and from medial-to-medial and from center-to-center measurements of interpedicular distance was 'good' with Pearson correlation coef-ficients of 0.60 and 0.63, respectively (p<0.001). No statistically significant relationships were found between the fracture levels, types, neurologic status of the patients, and the increase ratio of interpedicular distance or the ratio of canal compromise.
Depending on the correlation coefficients which were obtained in this study: To predict the canal compromise from the ratio of interpedicular distance increase is not a reliable method for all of the patients.
本研究旨在探讨胸腰椎爆裂骨折椎弓根间距增加率与椎管侵占率的关系。
研究纳入了骨科和创伤科治疗的 31 例胸腰椎爆裂骨折患者（18 男，13 女；平均年龄 30.8 岁[14-57 岁]）。患者的初始前后位 X 线片用于计算椎弓根间距增加率（内侧-内侧和中心-中心）。计算机断层扫描或磁共振图像的面积测量用于计算椎管侵占率。通过相关性和线性回归分析研究椎弓根间距增加率与椎管侵占率之间的关系。
椎弓根间距的内侧-内侧和中心-中心测量值之间存在“非常好”的相关性（皮尔逊相关系数：0.89，p<0.001）。椎管侵占率与椎弓根间距的内侧-内侧和中心-中心测量值之间的相关性为“良好”，皮尔逊相关系数分别为 0.60 和 0.63（p<0.001）。患者的骨折水平、类型、神经状态与椎弓根间距增加率或椎管侵占率之间无统计学显著关系。
根据本研究得出的相关系数：根据椎弓根间距增加率预测椎管侵占率并不是所有患者的可靠方法。
