【 摘 要 】

Category:Ankle, TraumaIntroduction/Purpose:As medical imaging of the syndesmosis prior to ankle injury is usually not available, researchers have diagnosed and surgically reduced syndesmotic disruptions based on presumed symmetry with the healthy contralateral limb. The purposes of this study are to quantify the degree of symmetry present in the DTFS using 3D CT modeling, and to compare the accuracy of common clinical two-dimensional (2D) measurements to 3D CT measurements for assessing syndesmotic symmetry and measuring diastasis.Methods:Bilateral lower limb CT (n=65) were assessed, were segmented, and reconstructed into 3D surface models, and an anatomically-defined coordinate system was applied to orient the 3D models uniformly. Symmetry was assessed three- dimensionally to overlap the left and right. The relative differences between the two fibulae were quantified in six degrees of freedom. For comparative purposes, four 2D measures were also measured. These measures included anteroposterior (AP), med...
