Quadrilateral plate fractures of the acetabulum: Classification, approach, implant therapy and related research progress

Figure 3 Application of the medial ilioischiatic plate in the acetabular fracture with central dislocation of the femoral head involving quadrilateral plate. A: Radiography of an acetabular fracture with central dislocation of the hip involving quadrilateral plate (QP); B and C: Three-dimensional CT reconstruction (the red arrow indicates a medially displaced QP fracture); D: Anterior column anatomical plate fixation (red arrow) does not prevent medial displacement of the QP fracture; E: Interference of the QP fracture with the medial ilioischiatic plate (shown by the red arrow); F: Postoperative X-ray.
