[Open pertrochanteric fracture of the femur and post-traumatic osteitis in a child : Interposition of a pedicled vascularized fibula to preserve the femoral head].

The free microvascular fibula diaphysis transplant as femoral neck replacement with preservation of the patient's own femoral head due to a severe infection situation represents a rare indication in the treatment of young patients. In the current literature, such surgical methods do not exist. In the case described here, the free microvascular fibula transplant serves as femoral neck replacement with preservation of the patient's own femoral head without any postoperative mobility restrictions. The depicted course of the disease not only shows the effectiveness of this form of treatment in aseptic femoral head necrosis, but also represents a possible treatment in severe infection situations after trauma.
