Background
Hip arthroplasty is currently the most effective method for clinically treating severe arthropathy, senile femoral neck fractures and partial intertrochanteric fractures. With the increasing of aging population, bone joint diseases are increasing, the hip joint replacement can reconstruct the functions of diseased joints, and can remarkably improve the working capacity and life quality of patients, and the hip joint replacement is widely applied at home and abroad as a mature treatment means.
The hip joint comprises a femoral head and an acetabulum, and the total hip joint replacement is to replace both the femoral head and the acetabulum, and then install the replaced femoral head into the replaced acetabulum, namely reset. Normal human anatomy, acetabulum and femoral neck are themselves anteverted with a degree; in order to reduce the dislocation of the hip joint after operation, the anteversion angle of the acetabulum and the femoral neck needs to be properly increased. Before reduction, the femoral head is positioned on the posterior superior medial side of the posterior acetabular rim, and if reduction is desired, the femoral head is passed over the superior posterior acetabular rim.
The existing restorer is cylindrical, and the front end is arc-shaped concave and is used for receiving the femoral head. Because the main flow path of the current total hip arthroplasty is the posterior lateral flow path of the hip joint, the direction of the force used in the resetting is the anterior inferior medial side, and the femoral head can be propped against the posterior edge of the acetabulum when the force is used forward, and the bone is difficult to pass the posterior edge of the acetabulum, thereby causing difficult operation. In particular, femoral head reduction can be very difficult when the hip joint is tighter or the acetabular anteversion is properly increased.
