Osteosynthesis of a femoral head fracture using the Ganz approach. a The position of the trochanteric osteotomy: The osteotomy exits just anterior to the most posterior insertion of gluteus medius proximally and the entire origin of vastus lateralis remains on the trochanteric fragment distally. b After the osteotomy of the trochanter, the osteotomized trochanter fragment, including the tendon of gluteus minimus, is reflected anteriorly. Through blunt separation, the tissue space between the tendon of piriformis and gluteus minimus is enlarged and gluteus minimus contracts upward, which contributes to adequately expose the capsule. c Make a Z-shaped capsule incision to further rotate outward and flex the femur. d After dislocation of the femoral head, lower the knee and rotate the affected leg, which can make the fracture can easily visualized, reduced, and stabilized
