Fractures of the femoral neck in patients between the ages of twelve and forty-nine years.
Femoral neck fractures in young adults have a poor prognosis because the incidence of non-union and aseptic necrosis is high. We reviewed the results in twenty-seven consecutive patients with a femoral neck fracture who were younger than fifty years and who were treated with a standard protocol at Harborview Medical Center from 1975 to 1981. There were twenty-two male and five female patients, and they ranged in age from twelve to forty-nine years (mean, 32.4 years). Twenty patients were involved in high-velocity trauma and twelve of them had significant injuries to other organ systems. One of the remaining seven patients had sustained the fracture while running, and in the other six the fracture was associated with a metabolic disorder. Eight patients had a Garden Stage-II fracture; twelve, Stage-III; and seven, Stage-IV. The fractures were fixed with multiple 6.5-millimeter cancellous screws after adequate closed reduction, which was usually performed within eight hours after injury. All of the fractures united and there were no wound infections. Aseptic necrosis of the femoral head developed in five patients (20 per cent), three of whom had symptoms at the time of writing and will require surgical revision of the hip.
