Abstract：
Tarso-metatarsal joints and naviculocuneiform joints comprising midfoot is the second most commonly involved joints following the first metatarsophalangeal joint in the foot. However, related factors of midfoot arthritis (MA) have been rarely reported. The bony structure and alignment can be more precisely assessed using Weight-Bearing Computed Tomography (WBCT) than conventional radiographs. Therefore, the aim of this study was to investigate risk factors for MA related to medical history and comorbid foot deformities using WBCT. WBCT data from September 2014 to April 2022 were extracted from a single referral hospital. All cases were divided into two groups by the presence of MA. Twenty-five potential related factors including demographics, etiology, and common co-occurring foot deformities were collected for comparison. Six hundred six cases (247 males and 359 females) among consecutive 1316 cases between September 2014 to April 2022 were selected. One hundred thirty-nine male cases (56.3%) and 210 female cases (58.5%) showed MA. In stepwise multiple logistic regression analysis, 5 factors remained statistically significant. The multivariate-adjusted odds ratios for age, laterality, body mass index (BMI), Progressive Collapsing Foot Deformity (PCFD), and lesser toe deformities (LTD) were 1.08, 1.54, 1.05, 6.62, and 3.03 respectively. Risk factors for MA associated with medical history and foot deformities included age, laterality, BMI, PCFD, and LDT.
摘要：
包括中足的掌-meta关节和Naviculoconeiform关节是继足部第一个meta趾关节之后的第二常见关节。然而,中足关节炎（MA）的相关因素很少报道。与常规射线照片相比，使用负重计算机断层扫描（WBCT）可以更精确地评估骨骼结构和对准。因此,这项研究的目的是使用WBCT调查与病史和合并症足部畸形相关的MA的危险因素。2014年9月至2022年4月的WBCT数据来自一家转诊医院。根据是否存在MA将所有病例分为两组。25个潜在的相关因素，包括人口统计学，病因学,收集常见的同时发生的足部畸形进行比较。在2014年9月至2022年4月的连续1316例病例中，选择了66例（男性247例，女性359例）。男性39例（56.3％）和女性210例（58.5％）显示MA。在逐步多元逻辑回归分析中，5个因素仍然具有统计学意义。年龄的多变量调整后的赔率比，偏侧性,体重指数（BMI），进行性塌陷脚畸形（PCFD），和较小的脚趾畸形（LTD）分别为1.08、1.54、1.05、6.62和3.03。与病史和足部畸形相关的MA的危险因素包括年龄，偏侧性,BMI,PCFD,LDT。证据级别：三级，回顾性病例对照研究。
