Imaging and Diagnosis of Olecranon Process Fractures

Initial Assessment

• Radiographs are the first-line imaging modality for suspected olecranon fractures to assess displacement, comminution, and joint involvement, as recommended by the American College of Radiology 1, 2
• CT without contrast is indicated when radiographs are normal or indeterminate but clinical suspicion for fracture remains high, as it can identify occult fractures of the olecranon and clarify fracture morphology, according to the American College of Radiology 1, 3
• Joint effusion on radiographs, indicated by posterior and anterior fat pad elevation, may suggest an occult elbow fracture in the context of trauma, as noted by the American College of Radiology 1, 4
