Location and displacement/distraction of mandible fractures
Location | No. | Percentage | Displ/Distr (none/mild [≤3 mm]) | Displ/Distr Mod or Greater | Comminuted* (% of all unifocal fractures in same location) |
---|---|---|---|---|---|
Parasymphyseal | 7 | 16% | 2 | 5 | 4 (57) |
Body† | 11 | 26% | 4 | 6 | 8 (73) |
Angle | 13 | 30% | 12 | 1 | 1 (8) |
Condyle or neck | 5 | 12% | 0 | 5 | 3 (60) |
Ramus | 2 | 5% | 2 | 0 | 0 |
Coronoid process | 1 | 2% | 1 | 0 | 0 |
Subcondylar | 2 | 5% | 2 | 0 | 0 |
Alveolar ridge | 2 | 5% | 2 | 0 | 0 |
Total | 43 | 100% | 26/43 | 17/43 | 16 (37) |
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.
