Fig. 4From: Digital anatomical study and clinical application of screw placement for quadrilateral plate fractures in the danger zoneA 51-year-old man was suffered serious traffic injuries. a-c: preoperative X-Ray, CT cross section and 3D reconstruction. The red arrow represents the displaced quadrilateral plate fracture. d-f: postoperative X-Ray, CT cross section and 3D reconstruction. Green arrow shows two hollow countersunk screws used to fix the quadrilateral plate. g-i: Postoperative CT-scan images were imported into Mimics software. Observation of the coronal plane and 3D model of the semi-pelvis shows that the insertion angle of the screws corresponded to that of our studyBack to article page
