ResumoThe early detection and management of wrist fractures may avert potential complications and patient morbidity. Five cases are described in which radiographically-occult fractures were clearly demonstrated by magnetic resonance imaging (MRI). These fractures were seen on MRI as a low signal linear band on T1- and T2-weighted images, with surrounding increased signal intensity from bone marrow oedema on T2-weighted images. In one case, intense oedema obscured the fracture line on the initial MR scan. MRI is useful in confirming the presence of a fracture, delineating its exact shape and location, and in the follow-up of these injuries during and after treatment.
