Haglund's deformity is clinically defined by the presence of retrocalcaneal tenderness, with previous radiographic parameters relying on calcaneal anatomic parameters that did not considering the influence of ankle motion on posterior calcaneal-Achilles impingement METHODS: Standing foot radiographs from 55 patients with clinically defined Haglund's deformity were compared to 50 control patients using previously described measurements and 2 new angular measurements based on the linkage between ankle rotation and posterior calcaneal-Achilles impingement. The ability of each measure to distinguish between Haglund's and control patients was assessed.
The combination of the angles to account for both increased calcaneal tubercle height and increased posterior calcaneal prominence could distinguish between the two patient groups (p = .018, Area under the curve = 63.2%). None of the previously published radiographic criteria were different between the two patient groups.
The proposed radiographic criteria were more predictive than previous criteria that did not address the role of ankle motion.
Haglund畸形在临床上的定义是跟腱后压痛，以往的影像学参数依赖于跟骨解剖参数，未考虑踝关节运动对跟骨后-跟腱撞击的影响。方法：使用先前描述的测量方法以及基于踝关节旋转与跟骨后-跟腱撞击之间联系的2个新角度测量方法，将55例临床诊断为Haglund畸形患者的站立位足部X线片与50例对照患者的进行比较。评估每种测量方法区分Haglund畸形患者和对照患者的能力。
综合考虑跟骨结节高度增加和跟骨后突出增加的角度，能够区分两组患者（p = 0.018，曲线下面积 = 63.2%）。两组患者之间，之前发表的影像学标准均无差异。
所提出的影像学标准比未考虑踝关节运动作用的先前标准更具预测性。
