Electronic Cast Radiograph Evaluation (e-CRE)

The ABO uses still shot images from Ortho Share 3D software to ask questions about the Electronic Cast Radiograph Evaluation on the Clinical Examination.  Please refer to the e-CRE Sample Cases to review the types of questions that can be expected for the e-CRE portion of the exam. Examinees will need to be familiar with landmark location, scoring parameters, etc. Examinees will NOT be scoring models in the Ortho Share 3D software on the exam.
