The value of colour flow Doppler ultrasound scanning in patients with suspected acute carpal scaphoid fracture has been examined. A prospective study of 78 patients with signs and symptoms of carpal scaphoid injury was undertaken over a period of 6 months. Both wrists of all patients were scanned within 12–72 h of injury. The radial artery and carpal scaphoid bone contours are visible using this type of imaging technique. The distance between the medial wall of the radial artery and the outer cortex of the scaphoid waist was measured. The scaphoid index is described and was calculated from this measurement. Patients were managed without knowledge of the ultrasound imaging result, using plain radiographs and clinical examination as the standard for determining the presence of a scaphoid fracture. All patients were followed to the resolution of symptoms. All 12 patients who were subsequently considered to have scaphoid fractures were identified using this imaging technique within 12–72 h after injury. We conclude that this imaging may be useful in the assessment of patients with carpal scaphoid fracture. It can be used early, as a supplementary investigation, in patients with suspected carpal scaphoid fracture in whom the initial plain radiographs are normal.
