Radiographic measurements are the gold standard in the management for preoperative surgical planning of hallux valgus deformity. Plantar pressure technology is a tool that is not commonly used to evaluate and manage hallux valgus patients, and few studies have reported the correlation of plantar pressure measurements and radiography.
A prospective cohort study was designed to analyze plantar pressure measurements and radiographic variables. The inclusion criteria were age over 18 years old, and diagnosis of hallux valgus requesting surgical correction because of discomfort, pain or difficulty with shoe wear. Plantar pressure measurements were performed using a platform. Radiographic data were obtained according to the guidelines of the AOFAS Committee on Angular Measurements.
A total of 114 patients met the inclusion criteria. Mean age of the patients was 50 years, and 94 patients (82.5%) were women. We found significant correlations between dynamic plantar pressure measurements and HVA, DMAA, and MDA. Mean pressure under third metatarsal head was the most associated plantar pressure measurement with hallux valgus angle and metatarsal declination angle. However, this association showed signs of weakness.
Hallux valgus angle and metatarsal declination angle had a minimal influence on plantar-loading parameters. Pressure values did not discriminate the magnitude of HV deformity. Others factors responsible for the observed plantar pressures pattern should be addressed.
放射测量是拇外翻畸形术前手术规划管理的金标准。足底压力技术是一种不常用于评估和管理拇外翻患者的工具，很少有研究报告足底压力测量与放射学的相关性。
设计了一项前瞻性队列研究，以分析足底压力测量和放射学变量。纳入标准为年龄大于 18 岁，因不适、疼痛或穿鞋困难而要求手术矫正的拇外翻诊断。使用平台进行足底压力测量。根据 AOFAS 角测量委员会的指南获取放射学数据。
共有 114 名患者符合纳入标准。患者的平均年龄为 50 岁，94 名患者（82.5%）为女性。我们发现动态足底压力测量与 HVA、DMAA 和 MDA 之间存在显著相关性。第三跖骨头下的平均压力是与拇外翻角和跖骨偏斜角最相关的足底压力测量值。然而，这种相关性显示出较弱的迹象。
拇外翻角和跖骨偏斜角对足底负荷参数的影响最小。压力值不能区分 HV 畸形的程度。应该解决导致观察到的足底压力模式的其他因素。
