An Algorithm for Acute Wrist Trauma

Abstract

A systematic approach to the acute traumatized wrist is of importance to achieve early diagnosis, with efficient use of advanced imaging modalities. In a 6-month period 641 patients aged 15 years or over were examined using an algorithm for acute wrist trauma in order to secure early and appropriate treatment. In 293 (46%) cases routine radiographic examination supplied sufficient information to establish a fracture diagnosis. All 33 scaphoid fractures (including five scaphoid non-unions) were demonstrated on the initial X-ray examination. In 56 patients (9%) scintigraphy proved useful for selecting cases in need of further radiographic examination. Among 31 patients with focal activity on bone scintigraphy, CT and/or tomography revealed eight distal radial fractures, one fracture of the ulnar styloid, and eight fractures of carpal bones. Fractures were revealed using tomography and/or “hot spot views” in patients with negative CT examinations suggesting that further examinations should be performed in cases with increased focal activity on bone scintigraphy and a negative CT examination.
