Background Suspected scaphoid fracture (SF) after a fall on an outstretched hand is a common presentation in the emergency department. Magnetic resonance imaging (MRI) or computed tomography (CT) has been suggested to assist in the diagnosis or exclusion of SF. Purpose To compare MRI and CT at diagnosing occult SFs. Material and Methods We routinely perform CT scans in patients with clinically suspected occult SF, after 7–10 days of injury following two negative radiographs. All eligible patients with a clinically suspected SF, but negative radiographs and a negative CT, underwent an MRI scan to assess further for evidence of occult fracture. Results A total of 100 patients were included in our study. MRI showed fractures in 16% of the time (in 15 patients) when plain radiographs and CT did not. Of these fractures, 8% were SFs. In addition to fractures, 10% had bone bruising. A total of 25% of patients with fractures and bone bruising were referred to the hand surgery team for further follow-up. Conclusion The study demonstrated that MRI would identify a radiographically occult SF more often than CT. This supports NICE guidelines which recommend MRI as the best early diagnostic tool for occult SFs. |
