5196 Mandible Fractures Among 4381 Active Duty Army Soldiers, 1980 to 1998

Abstract

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. population data to all hospitalizations among active duty Army soldiers. Results: We found the following frequencies for specific mandible fracture locations: angle 35.6%, symphysis 20.1%, subcondylar 14.2%, body 12.7%, condylar process 9.1%, ramus 4.5%, alveolar border 2.7%, and coronoid process 1%. The mechanisms of injury were separated into seven categories. Fighting accounted for 36.2%, automobile accidents for 18.6%, athletics for 13.6%, falls for 9.7%, motorcycle accidents for 3.1%, other land transport accidents for 3% and miscellaneous causes for 15.8%. A fewfracture locations appeared to be associated with specific mechanisms. Of 82 alveolar border fractures with known mechanisms, 37% resulted from automobile accidents. Of 1,094 angle fractures with known mechanisms, 48.6% resulted from fighting. Our data show that the vast majority of fractures were isolated to one location. 3,593 (82%) have only one fracture recorded, 764 (17%) have two fractures recorded, 21 (.4%) have three fractures recorded, and 3 (< 0.1%) have four fractures recorded. Associated injuries were rather common and included facial lacerations 1,236 (36.2%), non-mandible facial bone fractures 733 (16.7%), intracranial injury 402 (9.2%), internal injuries 229 (5.2%), fractures of the upper limb 295 (6.7%), fractures of the lower extremity 302 (6.9%), and cervical fractures 26 (0.6%).

Fratura de mandíbula: análise de 293 pacientes tratados no Hospital de Clínicas da Universidade Federal de Uberlândia

“…In sixty patients (20.5%), there was occurrence of open fracture, whose data coincided with the world literature owing to the fact that mandible fractures are normally caused by major impact trauma (traffic accident, sport, firearm and others) 2,7,9 . Cranio-maxillo-facial and other system traumas have also been concomitantly detected, in agreement with the literature 15,17 .…”

“…There are countries whose main cause of mandible fracture is related with sport activities, such as in Austria 16 . Others present interpersonal violence as the most common cause, such as Hawaii 17 , Zimbabwe 18 , Canada 19 . It is important to point out that there is predominance of occurrence of fracture at night hours and early Saturday and Sunday mornings, related with higher intake of alcoholic drinks 6,10 .…”

“…O principal fator etiológico das fraturas mandibulares observado nesta pesquisa foi o acidente com veículos automotores e coincidem com a grande maioria dos trabalhos pesquisados 1,3,6,7,10,[14][15][16] , seguidos de perto pelas agressões físicas que em outros estudos 3,[17][18][19] é o principal fator etiológico. O acidente esportivo foi a causa principal de fraturas mandibulares 20 .…”
