Falling on the outstretched hand is a common trauma mechanism. In contrast to fractures of the distal radius, which usually are diagnosed on plain film radiographs, identifying wrist injuries requires further diagnostic methods, e.g., MRI or CT. This article provides a review of the use of MRI in the most common traumatic wrist injuries, including scaphoid fractures, TFCC lesions, and tears of the scapholunate ligament. Early and selective use of MRI as a further diagnostic method in cases of adequate clinical suspicion helps to initiate the correct treatment and, thus, prevents long-term arthrotic injuries and reduces unnecessary absence due to illness. MRI shows a high reliability in the diagnosis of scaphoid fractures and the America College of Radiology recommends MRI as method of choice after X-ray images have been made. In the diagnosis of ligament and discoid lesions, MR arthrography (MRA) using intraarticular contrast agent has considerably higher accuracy than i.v.-enhanced and especially unenhanced MRI.
