成人获得性扁平足影像学检查

Image Examination of Adult Acquired Flatfoot Deformity

成人获得性扁平足畸形,可由胫后肌腱功能失用或胫后肌腱功能减退所引起,是以中足外展和后足外翻及内侧纵弓塌陷为特点的复杂性疾病,通常与进行性胫后肌腱力量减弱相关。目前有多种治疗方法,各有所长,治疗目标是获得前、后足准确的力线,重建足弓和维持后足及踝关节尽可能多的功能。在临床中,目前人们对于扁平足的认识并不充分,诊断主要根据症状、病史及影像学检查。临床主要表现为足外形的改变及后期疼痛,影像学检查中除了必要的足负重正侧位X线片和足正斜位X线片外,后足轴位X线片通过测量胫骨中轴线与跟骨轴线的距离,可为治疗方式的选择提供依据。

Adult acquired flatfoot deformity, causing by posterior tibial tendon dysfunction or insufficiency, mainly expresses midfoot abduction and hindfoot valgus as well as medial longitudinal arch collapse, and usually relates to progressive posterior tibial tendon weakening. There are many kinds of treatment methods, the purpose of the treatment is rebuilding arches with accurate forefoot and hindfoot alignment and maintain the flexibility of the foot and ankle as much as possible. In clinical, the people＇s understanding for adult acquired flatfoot is not sufficient, its diagnosis is mainly based on symptoms, medical history and image examination. Symptoms mainly expresses change of foot shape and later pain. Imaging examination, besides weight bearing lateral and oblique X-ray of foot, hindfoot axis X-ray, by measuring distance between the tibia axis and calcaneal axis, can be used to provide evidence for the selection of treatment.
