Deformity Correction with the iFIXation System: A New Era of Six-axis Correction Frames

The technology of computer-assisted six-axis frames is rapidly evolving. In this case report, we describe two cases of pediatric lower limb deformities treated by a novel hexapod device, the iFIXation system. For our knowledge, this is the first report in literature for its usage. The first case was a 14-years-old girl with posttraumatic shortening, varus and external rotation deformities of her lower limb around the ankle. All the deformities and shortening were corrected simultaneously with the iFIXation system. The second case was an 8-years-old girl with postinfection valgus and external rotation of the knee as well as shortening of the femur. Distal femoral deformities and shortening were simultaneously corrected by the iFIXation system and growth modulation to prevent recurrence of the deformity was done. The reported cases represent our earliest experience with the iFIXation system.
