ABSTRACT

The femoral neck fracture in children is rare and occurred by severe trauma and the treatment method and prognosis are different from adult, and it is difficult to treat due to frequent complication, which is so called “unsolved fracture”. Twelve cases of children's femoral neck fracture were treated at Chon Buk National University Hospital from July, 1981 to May, 1988 were analysed clinically and radiologically and following results were obtained 1. The commonest age group was between the age of 14 and 16 years and the ratio of boys and girls was 2l. 2. The main cause of fracture was traffic accident(6 cases) and fall down was 5 cases and slip down was 1 case. 3. According to the Delbet and Colona's classification, the transcervical fracture was most common type and displaced fracture was 8 cases. 4. Associated injuries were extremity fracture(3 cases) and pelvic bone fracture(2 cases) and head injury(2 cases), etc. 5. Seven cases were treated by open reduction and internal fixation and five cases by cast immobilization after skin or skeletal traction. 6. The commonest complication was coxa vara(5 cases) and other complication was avascular necrosis of femoral head(3 cases) premature epiphyseal closure(3 cases), nonunion (2 cases). 7. According to Ratliff's assessment of results, eight cases were good result and two fair results and two poor results. 8. Secondary operation (muscle pedicle bone graft, corrective subtrochanteric valgus osteotomy) was done in three cases and showed one good result, one fair result and one poor result.
