Early CT for suspected occult scaphoid fractures

In this study, the use of computed tomography (CT) early in the management of suspected occult scaphoid fractures was evaluated. We retrospectively reviewed the notes and radiology of patients who had scaphoid CT scans over the preceding 3 years. Eighty-four patients that had CT scans within 14 days from injury were identified. Of the CT scans, 64% (n = 54) excluded a fracture and these patients were promptly mobilized. No patients returned with any complications from this management. Overall, 36% of CT scans were abnormal (n = 30), 7% revealed occult scaphoid fractures, 18% revealed occult carpal fractures of the triquetrum, capitate, and lunate, respectively, and 5% revealed distal radius fractures. All patients diagnosed with fractures were successfully managed with plaster immobilization and there was one case of complex regional pain syndrome. Early CT alters therapeutic decision making in suspected occult fractures preventing unnecessary immobilization in a working population without increase in cost.
