Objective: In our this study, we evaluated the results which we obtained by using intramedulary Kirschner wire (K wire) in the children with femoral shaft fractures between the age 3 and 10.

Materials and Methods: Between the years 2007 and 2011, 39 patients (28 male, 11 female) with isolated femur fractures, whose intramedullary K wire were applied were studied.

Results: The average age of the patients was as 5,6 (age 3-10). All the femur fractures were in diaphysis and all of them were closed fractures. 11 of the fractures (28,2%) were transverse, 20 of them (51,3%) were oblique, 8 of them (20,5%) were spiral. The average operation time was determined as 55,38 (40-90) minutes. The average patient follow-up time was 17,07 (12-24) months, femur union was found almost in 7,10 (6-10) weeks. Approximately, in 6,87 (5-12) months, K wire were removed. In the first year after the operation, all the patients' had a full hip and knee range of motion and clinically rotational and angular deformity were not found out. In the last follow-up of these patients, it was observed that inequality reduced to 2,17 (0-5) mm, varus-valgus was average angularity 4,15º (0º-10º), sagittal plane was average angularity 3,10º (0º-10º) .

Conclusion: Intramedullary K wire presents the translation of fracture parts. We think that fixation through intramedullary K wire is the suitable choice in healing femoral shaft fractures in children between the age 3-10 of the fact that it can prevent extremity inequality and angular alignment.
