Fig 2.

A, Axial CT scan at the level of the glenoid fossa shows a right condylar fracture, with typical displacement. Note that the condylar head (solid arrow) is dislocated and displaced anteriorly and inferiorly from the glenoid fossa (asterisk) and that the ramus/neck component of the fracture (dashed arrow) is “telescoped” with respect to the condylar head component and displaced superiorly toward the glenoid fossa. Note the overlapping of the fracture fragments, with the condylar head component lying medial to the ramus/neck component. B and C, Coronal reformatted images through the mandibular condyle show the “telescoping,” with upward retraction of the ramus/neck component (dashed arrow) and anterior inferior medial displacement of the condylar head component (solid arrow) and resultant overlap of fracture fragments. This is the typical pattern of dislocation/displacement seen in this type of fracture and was present in all but 1 of the fractures that involved the condylar head or condylar neck. (The asterisk in C indicates the glenoid fossa.)
