Detection of Intra-Articular Screw Penetration of Proximal Humerus Fractures: Is Postoperative Computed Tomography the Necessary Imaging Modality?

摘要

Rationale and Objective: Screw penetration is the common complication of proximal humerus fractures treated with locking plates. This study compared postoperative plain radiography to computed tomography (CT) for their abilities in determining screw penetration, and was to evaluate whether advanced imaging modalities (two-dimensional [2D] CT; three-dimensional [3D] CT) could increase surgeons' level of confidence regarding their diagnoses.
