[Diagnosis, prevention and treatment of acute lateral ankle sprains].

Acute lateral ankle sprain is a frequent musculoskeletal injury, especially in sports. Most people recover within weeks, however, some have persistent symptoms for years. The Ottawa Ankle Rules can be used for initial investigation of a fracture in the ankle. Five days after the injury, a clinical examination should be completed. Both proprioceptive exercise and mechanical support can prevent ankle injuries and are also effective treatment modalities. Only few require surgery.
