Varus Derotation Osteotomy
The varus derotation osteotomy (VDRO) of the proximal femur is a procedure to redirect the femoral head toward the center of the acetabulum. The varus osteotomy reduces the neck shaft angle, while derotation of the shaft addresses femoral anteversion. This procedure is most frequently utilized in neuromuscular patients with hip displacement. Other indications include the treatment of coxa valga, and for containment of the femoral head in Perthes disease, as an alternative to, or in combination with, an innominate osteotomy. Simultaneous correction in the sagittal plane (flexion-extension) can also be achieved.
