A radiograph of the thoracolumbar spine in a 75-year-old woman with a history of back pain shows an anterior wedge compression fracture of Til. What influence does this observation have on the likelihood of a subsequent fracture?
Doubles the risk of another vertebral fracture
Doubles the risk of a proximal femoral fracture
Has little effect on the risk of a subsequent fragility fracture
Triples the risk of another vertebral fracture
Vertebral fractures are not only the most common fragility fracture, but also serve as powerful predictors of subsequent fracture. A vertebral fracture increases the likelihood of a further vertebral fracture fivefold and doubles the risk of a subsequent femoral neck fracture.
