The adult acquired flatfoot deformity resulting from posterior tibial tendon dysfunction is the result of rupture of the posterior tibial tendon as well as key ligaments of the ankle and hindfoot. Kinematic studies have verified certain levels of deformity causing hindfoot eversion, lowering of the medial longitudinal arch and forefoot abduction. The condition is progressive and left untreated will cause significant disability. Bracing with ankle-foot orthoses has shown promising results in arresting progression of deformity and avoiding debilitating surgery. Various types of ankle-foot orthoses have been studied in terms of effects on gait as well as efficacy in treatment.
成人因胫后肌腱功能障碍导致的获得性平足畸形是胫后肌腱以及踝关节和后足关键韧带断裂的结果。运动学研究已经证实，一定程度的畸形会导致后足外翻、内侧纵弓降低和前足外展。这种情况是渐进性的，如果不治疗会导致严重残疾。使用踝足矫形器进行支具治疗在阻止畸形进展和避免致残性手术方面已显示出有希望的结果。已经对各种类型的踝足矫形器在步态影响和治疗效果方面进行了研究。
