Evaluation et traitement de lentorse externe de la cheville dans un milieu de soins de première ligne: la radiographie systématique est-elle essentielle?

摘要

The authors describe the presentation, clinical evaluation and treatment of 151 patients (mean age 36.3 years) who presented to an outpatient clinic or the emergency department between Oct. 29, 1984, and Apr. 15, 1985, for a lateral ankle sprain. About 60% of the sprains were considered minor. Although 141 patients underwent simple radiography of the ankle on the first visit, only five fractures were identified. All the fractures were uncomplicated and were treated conservatively. No common criteria could be identified to explain why some patients with sprains of moderate severity were referred to an orthopedist while others were not. Of the 53 patients interviewed, 22 still had some limitation of physical activity 6 weeks after the sprain. The presence of malleolar soft-tissue swelling, pain in the bony structures and inability to bear weight should raise the suspicion of a fracture. If radiography had been limited to patients with these signs, no fracture would have been missed, and radiography would have been avoided in 70 cases.
