踝关节严重创伤的救治标准

Ankle injuries are frequently diagnosed and treated in United States emergency departments (ED) with an incidence of approximately 200 visits per 100,000 person-years . Of patients with acute ankle injuries undergoing radiographic evaluation the incidence of ankle fracture varies widely with season, athletic activity , and practice setting, ranging from 2.4% in outpatient sports medicine centers to greater than 20% in the ED setting . Recent evidence-based clinical treatment guidelines and systematic review of economic analyses support the role of radiography in evaluation of select patients suspected of having an ankle fracture with a limited role of cross-sectional imaging primarily as a tool for preoperative planning and as a problem-solving technique in patients with persistent symptoms and suspected of occult fracture.
