While podobarometric techniques have been applied to the study of pressures in Hallux Valgus (HV), little is known about its clinical and radiological determinants. So, the aim of the present study was to determine the plantar pressure pattern in participants with mild HV, comparing to a control group, and their clinical and anthropometric determinants. Biofoot/IBV(®) in-shoe system was used to evaluate 79 participants with mild HV. Computerized measurements of the 1st intermetatarsal angle (IMA) and the hallux abductus angle (HAA) were made on antero-posterior radiographs. The clinical outcome was assessed using the AOFAS score. The dependent baropodometric variables and the independent clinical and anthropometric variables were subjected to a multiple regression analysis. In both groups, the highest average pressure was in the 2nd metatarsal head (MTH). The mean pressure under the Hallux was significantly higher in HV group (controls, 146.5±92.5kPa; HV, 328.5±113.2kPa; p<0.001). An 18.6% of average pressure under the 1st MTH was accounted for pain, first ray alignment and total AOFAS score. Variations of the HAA explained 26.8% of the mean Hallux pressure. Women with mild HV present with pathologically increased pressure under the Hallux, which is caused by the altered alignment of the first ray. Pain and clinical result were associated with the pressure under the 1st MTH and the remaining variables were only moderate predictors of dynamic plantar pressures.
虽然类似的压力测量技术已经应用于研究拇外翻（HV）的压力，但对于其临床和影像学决定因素知之甚少。因此，本研究旨在确定轻度 HV 患者的足底压力模式，并与对照组进行比较，同时分析其临床和人体测量学决定因素。使用 Biofoot/IBV（®） 鞋内系统评估了 79 名轻度 HV 患者。在前后位 X 线片上对第一跖骨间角（IMA）和拇外展角（HAA）进行了计算机测量。使用 AOFAS 评分评估临床结果。将依赖的足压变量和独立的临床和人体测量变量进行多元回归分析。在两组中，第二跖骨头（MTH）的平均压力最高。HV 组的拇趾下平均压力显著高于对照组（对照组，146.5±92.5kPa；HV 组，328.5±113.2kPa；p<0.001）。第一跖骨下平均压力的 18.6%由疼痛、第一跖骨排列和 AOFAS 总分解释。HAA 的变化解释了拇趾下平均压力的 26.8%。患有轻度 HV 的女性，第一跖骨下的压力会出现病理性增加，这是由第一跖骨排列的改变引起的。疼痛和临床结果与第一跖骨下的压力以及其他变量相关，而其余变量只是足底动态压力的中度预测因素。
