  • Note:—Displ/Distr indicates displacement and/or distraction; Mod, moderate.

  • * Comminuted includes fractures that may or may not be associated with condylar subluxation; 5/7 fractures with condylar subluxations were comminuted.

  • The films for 1 of the body fractures were not available, so Displ/Distr could not be quantified.
