Photograph of the femur internal rotation reduction method (FIRM) used for iliac intramedullary stabilization. Reduction is performed by internal rotation of the femur with the knee bent and ankle held while the patient is in the prone position (left). During the femur internal rotation reduction method for iliac intramedullary stabilization, the femur is internally rotated to reduce the bone fragment by manipulation of the lateral rotator muscles and surrounding soft tissues (right).
