Investigation of the Association Between the Acute Ankle Injury Caused by Fall From Own Height and Body Mass Index.

In the emergency settings, increased body mass index (BMI) is a risk factor for traumatic orthopedic injuries. The aim of this study was to assess the association between the acute ankle injuries (sprain or fracture) and BMI. This prospective cohort study included patients ≥18 years of age with acute traumatic ankle injuries (either sprain or fracture) caused by fall from own height when walking at ground level and who received primary treatment at the emergency room of a university hospital between May and October 2017. Of the 107 patients who met the inclusion criteria, 58 (54%) patients experienced acute ankle sprains and 49 (46%) experienced acute ankle fractures. No significant association was detected between fracture severity (as assessed by the Danis-Weber classification) and BMI (p = .860). The most frequent ankle injury in patients with normal BMI was ankle sprain. In our cohort, obesity was not the primary determinant of the severity of ankle injury. However, age was a key determinant of the type of injury; patients >30 years of age were 20% more likely to suffer an ankle fracture.
