【 摘 要 】

Category:OtherIntroduction/Purpose:Evaluation and management of osteochondral lesions of the talus (OLTs) often warrant advanced imaging studies such as CT and/or MRI. While MRI has its advantages in determining the degree of cartilage damage, stability of the fragment and edema, CT imaging is better delineates the osseous anatomy and extent of the lesion. The latter imaging modality offers increasing acuity and resolution in characterizing the complex osteochondral landscape via three-dimensional (3D) reconstructions. It is possible that orthopedic surgeons may overestimate the size and misinterpret the morphology of OLT from conventional MRI and CT thereby influencing treatment strategies. The purpose of this study is to determine the utility of a novel means to estimate the true-volume of OLTs using 3D reconstructed images and volume analysis.Methods:After IRB approval, an institutional radiology database was queried for patients with OLTs and compatible CT scans between 2011 and 2016. Fourteen patient...
