In spite of the common occurrence of pes planus and multiple operations that have been reported to relieve the associated symptoms, there is little published on the relative contribution of various structures to stabilization of the arch of the foot. Twelve fresh-frozen human cadaveric feet were loaded along the tibial axis with compressive loads of 230, 460, and 690 newtons with the specimens intact and after sequential sectioning of plantar fascia, plantar ligaments, and spring ligament. Structures were sectioned in six different sequences and changes in vertical and horizontal dimensions of the medial arch were measured. The highest relative contribution to arch stability was provided by the plantar fascia, followed by plantar ligaments and spring ligament. Plantar fascia was a major factor in maintenance of the medial longitudinal arch. Its division in the cadaveric feet decreased arch stiffness by 25%.
尽管扁平足很常见，且已有多种手术可缓解相关症状的报道，但关于各种结构对足弓稳定的相对贡献的研究却鲜有发表。对12只新鲜冷冻的人尸体足沿胫骨轴线施加230、460和690牛顿的压缩载荷，分别在标本完整时以及依次切断足底筋膜、足底韧带和弹簧韧带后进行测量。结构按六种不同顺序切断，并测量内侧足弓垂直和水平尺寸的变化。对足弓稳定性贡献最大的是足底筋膜，其次是足底韧带和弹簧韧带。足底筋膜是维持内侧纵弓的主要因素。在尸体足中切断足底筋膜会使足弓刚度降低25%。
