SUPERhip Reconstruction with 130° Blade Plate for Congenital Femoral Deficiency Patients

A. This is a patient with congenital femoral deficiency with delayed bone formation in the neck of the femur. B. A blade plate is inserted into the center of the femoral head over a wire. C. In the first osteotomy (bone cut), a triangular piece of bone is removed from the side of the femur.

C. In the first osteotomy (bone cut), a triangular piece of bone is removed from the side of the femur.

D. The second bone cut removes a trapezoid-shaped piece of bone. E. The two ends of the femur are joined, and the orientation of the femur and knee is normalized. F. The femur shaft is secured to the plate with screws.

F. The femur shaft is secured to the plate with screws.

G. A channel in the bone is created parallel to the blade plate, and it is filled with bone morphogenetic protein (BMP). This off-label use of BMP stimulates the growth of new bone. A Dega osteotomy is performed to provide coverage to the femoral head.
H. The trapezoid-shaped bone graft, taken from the earlier bone cut (D.), is used to stabilize the Dega osteotomy.
I. A spica cast is used to protect the bone for six weeks while the bone heals.
