title: Bilateral midshaft femoral fractures in an adolescent baseball player.
abstract: Bone disease, specifically low bone mineral density, is a common and undertreated complication that begins during childhood in patients with cystic fibrosis (CF). This case describes a male baseball player, aged 14years, with undiagnosed CF who sustained a left midshaft femoral fracture while running toward base; 8months later, he sustained a right midshaft femoral fracture under similar conditions. After the second fracture, further evaluation revealed low bone mineral density and CF. There is no previously published report of pathologic fractures occurring in the femoral shaft in an athlete with undiagnosed CF. Patients with CF have a higher fracture rate. Low-energy fractures of major bones in athletically active individuals should be viewed with suspicion for an underlying process.
