A Novel Fixation System for Acetabular Quadrilateral Plate Fracture: A Comparative Biomechanical Study

Figure 2

(a)–(f) The operative procedure of the AFRIF technique for quadrilateral plate fracture. First the set bolt is loosened (a); then the segmental plates of inner wall (b) and ilium (c) were placed in the appropriate location of quadrilateral plate and the ilium, respectively. The segmental plate of ilium was fixed first (c), and then a Mayo clamp is placed from the anterior inferior iliac spine to an appropriate hole in the segmental plate of inner wall which acts as a direct reduction force on the quadrilateral plate (d). After obtaining anatomical reduction of the quadrilateral plate fracture, the set bolt of the AFRIF was tightened (e) to gain a fixed angle between the segmental plate of inner wall and ilium in which the reduction can be maintained. (f) Postoperative X-ray shows that the quadrilateral plate fracture was fixed by the AFRIF.
