The geographic incidence and treatment variation of common fractures of elderly patients

Fractures of the hip, wrist, proximal humerus, and ankle frequently are observed among the elderly patient population in the United States. The Medicare patient population has shown dramatic geographic variation in the rates of these common fractures, with an increased incidence observed throughout the Southeast. Treatment (surgical versus nonsurgical) is also highly variable and dependent on the geographic location but not necessarily on the type of injury. Whereas regional variation in medical treatment may be attributed to variations in practice patterns, the etiology behind the dramatic variations in fractures is less well-defined and is likely multifactorial, related to environmental, occupational, genetic, or nutritional factors.
