踝关节撞击的诊断主要通过临床检查进行，而医学成像用于严重程度分期和治疗指导。撞击症状与医学图像中可见的区域三维 (3D) 骨形状变化之间的关联尚未得到系统探索，我们也不知道这种关系的类型和程度。在这项横断面病例对照研究中，我们假设 3D 距骨形状可用于定量地表达有撞击的脚踝与无撞击的脚踝之间的区别形状变化，我们的目的是表征和量化这些变化。我们使用统计形状建模（SSM）方法来确定区分撞击脚踝和非撞击脚踝的最普遍的形状变化模式。对统计形状模型的紧凑性和并行分析测试的结果确定了 8 个突出的形状变化模式 (MoV)，约占形状总体 3D 变化的 78%，其中两种模式捕获了撞击脚踝和非撞击脚踝之间的区分特征（p 值为 0.023 和 0.042）。目视检查证实，这两种形状模式捕捉距骨前部和后部的异常，代表了前踝和后踝撞击的两个主要骨危险因素。总之，在这项使用 SSM 的研究中，我们发现了与骨性踝关节撞击显着相关的形状 MoV。我们还说明了 SSM 对手术计划的潜在指导。
Diagnosis of ankle impingement is performed primarily by clinical examination, whereas medical imaging is used for severity staging and treatment guidance. The association of impingement symptoms with regional three‐dimensional (3D) bone shape variaties visible in medical images has not been systematically explored, nor do we know the type and magnitude of this relation. In this cross‐sectional case‐control study, we hypothesized that 3D talus bone shape could be used to quantitatively formulate the discriminating shape variations between ankles with impingement from ankles without impingement, and we aimed to characterize and quantify these variations. We used statistical shape modeling (SSM) methods to determine the most prevalent modes of shape variations that discriminate between the impinged and nonimpinged ankles. Results of the compactness and parallel analysis test on the statistical shape model identify 8 prominent shape modes of variations (MoVs) representing approximately 78% of the total 3D variations in the population of shapes, among which two modes captured discriminating features between impinged and nonimpinged ankles (p value of 0.023 and 0.042). Visual inspection confirms that these two shape modes, capturing abnormalities in the anterior and posterior parts of talus, represent the two main bony risk factors in anterior and posterior ankle impingement. In conclusion, in this research using SSM we have identified shape MoVs that were found to correlate significantly with bony ankle impingement. We also illustrated potential guidance from SSMs for surgical planning.
