成人获得性扁平足通常以纵弓缺失、后足外翻和前足外展为特征，但在单个关节水平上的精确畸形尚未得到充分描述。对37例扁平足患者进行模拟负重CT扫描和X线平片检查。评估后足和足中部关节的关节炎退化程度，并沿足弓内侧柱沿着研究畸形的位置。约三分之一的距舟关节、距下关节和跟骰关节出现中度至重度退化。足弓内侧柱在一些足中通过距舟关节塌陷，在另一些足中通过内侧舟楔关节塌陷，但很少通过两者。第一跗跖关节半脱位也是一个常见的发现。在这个小系列中，退行性关节炎的程度和关节畸形的数量都与患者的年龄无关。此外，未观察到足畸形与关节退变之间的相关性。
Adult acquired flatfoot is generally characterized by loss of the longitudinal arch, hindfoot valgus, and forefoot abduction, but the precise deformity has not been adequately described at the level of individual joints. Simulated weightbearing CT scans and plain radiographs of 37 symptomatic flat feet were examined in this study. The degree of arthritic degeneration was assessed in the major hindfoot and midfoot joints, and the location of deformity was studied along the medial column of the arch. Moderate to severe degeneration was seen in about one-third of talonavicular, subtalar, and calcaneocuboid joints. The medial column of the arch collapsed through the talonavicular joint in some feet, through the medial naviculocuneiform joint in others, but rarely through both. First tarsometatarsal joint subluxation was a frequent finding as well. In this small series, neither the degree of degenerative arthritis nor the amount of joint deformity was seen to correlate with patient age. Furthermore, no correlation was observed between foot deformity and joint degeneration.
