Epidemiology of sprains in the lateral ankle and foot

Abstract

The epidemiology of sprains in the lateral ankle and foot was investigated in a prospective study at the casualty ward at Hillerød County Hospital. During one year, 766 patients were registered. The overall sprain incidence was 7/1000 person-years. The incidence was highest for young males. After the age of 40 years, the incidence was higher for women than for men. Most sprains were sustained during sport, but, with increasing age, other activities became dominant. Sixty-one percent of the lesions were located around the lateral ankle, and 24% were located on the lateral midfoot.
