Rotational osteotomy of the base of the femoral neck involves osteotomy at the intertrochanteric level and rotation of the femoral head. That is to rotate the avascular collapse of the femoral head to the nonweight-bearing area of the hip joint, thus effectively avoiding further collapse of the femoral head necrosis. Clinical has achieved a certain effect. However, there are also some problems in the operation, such as the individual difference of the neck-shaft angle and the anteversion angle of the femoral neck of the affected hip joint among different patients, the nonunion of the osteotomy end, the mismatch of the relationship between the head and the acetabulum, and the direction and angle of the head rotation. The combined three-dimensional printing technology is expected to ensure the accuracy of osteotomy, to solve the adverse complications, and to improve the surgical efficacy.
