外翻与足弓塌陷的相关性研究

Correlation between Hallux Valgus and Medial Arch Collapse

目的:研究外翻与足弓塌陷的相关性。方法:对2018年10月至2019年12月就诊的外翻患者89例(160足)纳入研究。根据临床影像学资料,将62例(108足)纳入足弓塌陷组,将27例(52足)纳入足弓正常组。分别收集两组患者基线资料及足部负重正侧位X线片,记录跟骨倾斜角(CPA)及内侧第一跖距角(Meary’s Angle),运用二元逻辑回归及多元线性回归分析,研究CPA、Meary’s角与外翻的关系,分析外翻与足弓塌陷的相关性。结果:两组双足CPA、Meary’s角、外翻角(HVA)数据存在组间差异性,差异有统计学意义(P<0.05);多元线性回归分析表明足弓正常组与足弓塌陷组双足外翻角与CPA存在相关性(P<0.05),与Meary’s角相关性较弱(P>0.05);二元逻辑回归分析显示,二分类变量足弓塌陷与HVA及第1,2跖骨间夹角(IMA)有相关性(P<0.05)。结论:外翻与足弓塌陷存在相关性,在外翻的预防、诊断与治疗过程中应该注意弓的生理结构,采取合理的干预措施和手术方案,以获得更好的临床疗效。

Objective:To study the correlation between hallux valgus and medial arch collapse.Methods:A study of 89 patients with hallux valgus treated from October 2018 to December 2019 was included.According to clinical imaging,62 cases(108 feet) were included in the medial arch collapse group,and 27 cases(52 feet) in the normal arch group.Baseline data and lateral foot X-ray information of two groups of patients were collected,and binary logistic regression and multiple linear regression analysis were used to study the relationship among calcaneal pitch angle(CPA),Meary’s angle and hallux valgus angle(HVA),to study correlation between hallux valgus and medial arch collapse.Results:There were statistically significant differences between the two groups in CPA,Meary’s angle,and HVA(P<0.05).Multiple linear regression analysis showed that there was a correlation between CPA and HVA in the two groups(P<0.05),and the correlation with Meary’s angle was not significant(P>0.05).Binary logistic regression analysis showed that there is a correlation between medial arch collapse with HVA and IMA(P<0.05).Conclusion:There is a correlation between hallux valgus and medial arch collapse.In the process of prevention,diagnosis and treatment,physiological structure of the bow are worthy of notice,and reasonable intervention measures and surgical plans should be adopted to obtain better clinical efficacy.
