本研究的目的是记录接受过骨性前踝撞击手术治疗的患者中发生的骨赘大小和位置的放射线趋势。所有 31 个月内接受前踝骨赘手术切除的患者均被确定。选择术前可进行 CT 扫描的 9 例患者（110 踝）作为研究组。回顾性分析该组患者的术前基本特征（年龄、性别、症状、运动史、全身性疾病、被动背屈）。在平片上测量骨赘大小，并使用轴向 CT 图像通过参考距骨穹顶的中线来确定胫骨和距骨骨赘的位置。 95% 置信区间表明距骨骨刺峰值位于中线内侧，胫骨骨刺峰值位于中线外侧，并且骨刺通常不会彼此重叠。此外，胫骨刺比距骨刺宽，并且距骨刺通常从距骨颈的内侧边缘向内侧突出。因此，有证据表明前胫距骨赘可能具有相对一致的形成模式，距骨骨刺出现在距骨颈的内侧，而胫骨骨刺在中线外侧达到峰值。这些信息如果得到更多患者的证实，可能会深入了解前踝撞击的病理生理学，并有助于通过开放和关节镜手术切除这些病变。
The purpose of this study was to document radiographic trends in the size and location of osteophytes occurring in patients who have undergone surgical treatment of bony anterior ankle impingement. All patients over a period of 31 months who had undergone surgical excision of anterior ankle osteophytes were identified. 9 patients (110 ankles) in whom preoperative CT scans were available were selected as the study group. This group was retrospectively reviewed in terms of basic preoperative characteristics (age, sex, symptomatology, sports history, systemic disease, passive dorsiflexion). Osteophyte size was measured on plain lateral radiographs, and axial CT images were used to determine both tibial and talar osteophyte location by referencing them to the midline of the talar dome. 95% confidence intervals demonstrated that the talar spur peak lies medial to the midline, the tibial spur peak lies lateral to the midline, and the spurs typically do not overlap each other. Further, the tibial spur is wider than the talar spur, and the talar spur usually protrudes medially off the medial edge of the talar neck. Thus, there is evidence that anterior tibiotalar osteophytes may have a relatively consistent pattern of formation, with the talar spur occurring on the medial aspect of the talar neck, and the tibia[ spur peaking lateral to the midline. This information, if substantiated with additional patients, may provide insight into the pathophysiology of anterior ankle impingement, as well as facilitate the open and arthroscopic approaches toward resection of these lesions.
