A radiographically documented intra-uterine femoral fracture

Mid-trimester fracture of femur in a normal fetus

We report a case of an intrauterine fracture of the femur detected at routine mid-trimester sonography in an otherwise normal fetus. There was no associated maternal trauma. At birth, callus formation was palpable and confirmed by radiography. Absence of further fractures despite normal childhood activity and other features precluded a diagnosis of skeletal dysplasia. Although such an event is extremely rare, the possibility of an intrauterine origin should be considered in the differential diagnosis of battered baby syndrome presenting with a single fracture.
