For successful reconstruction of osteochondral lesions of the talus, the anatomic configuration of the talar edge must be respected. This study evaluated the radiographic configuration of the talar edge in the anterior-posterior (AP) view by analyzing medial and lateral talar edge angles and radii in 81 patients with a true AP view and without ankle pathology. The mean lateral talar edge angle was 91.8 degrees , and the mean medial talar edge angle was 110.0 degrees . The medial frontal talar edge radius was 4.8 mm and the lateral 3.5 mm, respectively. No correlation between angle and radius was found. These results revealed a significant difference between the medial and the lateral talar edge configuration. This may be due to the three-dimensional function of the human ankle joint. No study so far has addressed these differences radiologically. These differences should be addressed in the reconstruction of osteochondral lesions and be included in the preoperative planning.
为成功重建距骨的骨软骨损伤,必须尊重距骨边缘的解剖结构。本研究通过分析81例具有真正前后位(AP)视图且无踝关节病变患者的距骨内侧和外侧边缘角度及半径,评估了前后位(AP)视图下距骨边缘的影像学结构。距骨外侧边缘平均角度为91.8度,距骨内侧边缘平均角度为110.0度。距骨内侧前缘半径分别为4.8毫米,外侧为3.5毫米。未发现角度与半径之间存在相关性。这些结果揭示了距骨内侧和外侧边缘结构之间存在显著差异。这可能归因于人体踝关节的三维功能。迄今为止,尚无研究从放射学角度探讨这些差异。在骨软骨损伤的重建中应考虑这些差异,并将其纳入术前规划。
