Pes planus of the foot is believed to be an important etiological factor in hallux valgus. This study compares the degree of pes planus in normal and hallux valgus feet. The arch index, or ratio of the area of the middle third of the foot to the total footprint area, was calculated on 128 footprints. An unpaired t-test determined no significant difference between the arch index of 32 11-year-old children with hallux valgus and 11-year-olds with no first metatarsophalangeal joint deformity (P greater than .05). The height of the arch is not relevant to the hallux valgus deformity. Arch supports designed to raise the height of the arch can play only a palliative role in the management of the condition.
足部扁平足被认为是拇外翻的一个重要病因。本研究比较了正常足和拇外翻足的扁平足程度。在128个脚印上计算足弓指数，即足中部三分之一区域面积与总脚印面积的比值。采用非配对t检验，结果显示32名患有拇外翻的11岁儿童与11名无第一跖趾关节畸形的儿童的足弓指数之间无显著差异（P大于0.05）。足弓高度与拇外翻畸形无关。旨在提高足弓高度的足弓支撑物在该病症的治疗中仅能起到缓解作用。
