Comparison of antegrade and retrograde cross pin fixation in the surgical treatment of pediatric supracondylar femur fractures: a biomechanical study

The incidence of pediatric supracondylar femur fractures has been reported at different rates in the literature and this rate varies between 1% and 12%. Approximately 57% of these fractures are displaced [1 –3]. The medial and lateral heads of the gastrocnemius muscle, which attach just behind the femoral condyles, the medial hamstring muscles, the adductor magnus muscle which attach to the adductor tubercle, and the quadriceps femoris muscle, create a deforming force on the fracture. In particular, the extension deformity of the distal part is caused by the pulling effect of the gastrocnemius muscle, and the varus deformity is caused by the pulling of the adductor magnus muscle [1].
