The femoral neck fracture in children are extremely rare and occur secondary to severe trauma. Many authors recommend early anatomical reduction and firm internal fixation because of many complications after treatment. Eleven displaced femoral neck fractures in children who were treated at the Keimyung University Dong San Medical Center from February, 1989 to February, 1993. Following results were obtained, after clinical and radiological evaluations. 1. Fractures of the femoral neck in children occurred from five to sixteen years, the highest inci dence was between ten and thirteen years of age. 2. The main causes of the fracture were traffic accident in 9 cases. 3. 10 cases were treated by arthrotomy, open reduction and internal fixation and one by closed reduction and internal fixation. 4.
