The femoral neck fracture in childhood is rare and occurred by severe trauma. Its treatment method and prognosis are different from adult, and(it was) difficult to treat due to frequent complication. So the femoral neck fractures in children are called as unsolved fracture.

Eleven cases of childrens femoral neck fracture were treated by closed reduction and internal fixation using cancellous screws or Knowles pins at Kwang lu Christian Hospital from January 1986 to January 1992, and were analysed clinically and radiologically.

According to classification of Delbet and Colona, the transcervical fracture were 6 cases and the cervicotrochanteric fracture f cases. 10 of the eleven cases were displaced fractures. Avascular necrosis was evident in 6 cases(54.5%) and all of them were displaced fracture initially. 2 cases of avascular necrosis were treated with Intertrochanteric varus osteotomy with angle blade plate.
