慢性腰痛患者矢状位参数特征分析

目的 探讨慢性腰痛患者脊柱-骨盆矢状位参数特征及其与慢性腰痛的关系。方法 选择2019年7月至2021年6月在我院骨科门诊就诊的249例慢性腰痛患者(腰痛组)和同期86例无症状成人(对照组)作为研究对象。收集两组研究对象的一般资料,在脊柱全长正侧位X线片上测量胸椎后凸角(TK),腰椎前凸角(LL),LL-TK,骶骨倾斜角(SS),骨盆倾斜角(PT),骨盆入射角(PI),SS-PT,LL-PI,矢状位垂直轴(SVA)等矢状位参数,比较两组研究对象一般资料和矢状位参数的差异。结果 两组研究对象年龄、性别、体质量指数(BMI)差异均无统计学意义(P均>0.05)。腰痛组和对照组TK、LL-TK、SS、PI和SS-PT差异均有统计学意义(P均<0.05),而两组间LL、PT、LL-PI和SVA差异无统计学意义(P均>0.05)。与正常成人相比,腰痛组出现低SS和LL伴有小PI的比例较高,而对照组中出现正常或高SS伴有正常或高PI的比例较高。结论 慢性腰痛患者与对照组脊柱-骨盆矢状面参数不同,特别是大TK、小SS、小PI的慢性腰痛患者比例较大,提示这一特定模式与慢性腰痛的存在有关。

Analysis of sagittal spino-pelvic parameters in chronic low back pain

Objective To explore the characteristics of sagittal spino-pelvic parameters in patients with chronic low back pain and their relationships with chronic low back pain. Methods From July 2019 to June 2021, 249 patients with chronic low back pain (LBP group) and 86 asymptomatic adults (control group) in our orthopaedic clinic were selected. Collect the general data of the two groups patients, measure the thoracic kyphosis angle (TK), lumbar lordosis angle (LL), LL-TK, sacral inclination angle (SS), pelvic inclination angle (PT), pelvic incidence angle (PI), SS-PT, LL-PI, sagittal vertical axis (SVA) and other sagittal parameters on the full length anteroposterior and lateral X-ray films of the spine, and compare the differences between the two groups. Results There was no significant difference in age, gender and body mass index (BMI) between the two groups (P>0.05). There were significant differences in TK, LL-TK, SS, PI and SS-PT between the two groups (P<0.05), while there was no significant difference in LL, PT, LL-PI and SVA between the two groups (P>0.05). Compared with control group, the proportion of low SS and LL accompanied by small PI in LBP group was higher, while the proportion of normal or high SS accompanied by normal or high PI in the control group was higher. Conclusion The sagittal spino-pelvis parameters of patients in LBP group were different from those in control group. Especially the proportion of patients with large TK, small SS, and small PI in LBP group was large, suggesting that this particular pattern was related to chronic low back pain.
