Abstract

The radiograph is rapidly superseding the clinical examination as the diagnostic tool for acute ankle injuries. Twenty-four independent variables which might help distinguish between soft tissue injuries and fractures at the ankle were identified and then used prospectively to study 150 consecutive patients with ankle injuries. Nineteen patients had fractured ankles (12.7 per cent) and 131 (87.3 per cent) had soft tissue injuries. Only the patient's ability to bear weight on the injured ankle and the presence of tenderness over the lateral aspect of the ankle below the malleolus proved to be helpful. When these 2 signs were present together, regardless of all other variables, there was a 97.5 per cent probability of soft tissue injury P < 0.005). This study suggests that careful patient assessment will permit more discriminating use of ankle X-rays.

    Citation Excerpt :

    The musculoskeletal expert panel reviewed pertinent articles dealing with patients with ankle injuries. The reviewed articles were concerned primarily with missed fractures and improving fracture detection [1-4] or with the establishment of clinical criteria that would decrease the number of ankle radiographs without missing significant injuries [5-15]. Ankle injuries are frequently diagnosed and treated in US emergency departments (EDs) with an incidence of approximately 200 visits per 100,000 person-years [16,17].

    2007, European Journal of Radiology
    Citation Excerpt :

    In most hospitals a routine X-ray of the ankle is made in case a patient visits the First Aid Department with a painful swollen ankle. The prevalence of an ankle fracture in patients with a painful swollen ankle that visit the First Aid Department of a Western hospital is up to 15% [4–9]. Decisional rules have been proposed to minimize the number of routine X-rays.
