Humerus proximal end fractures constitute 45% of the humerus fractures. Humerus proximal end fractures are encountered at the rates of 4-5% in the extremity fractures. This rate increases to 76% in the cases over 40 years old. Twenty percent of these fractures are displaced fractures and they require surgical intervention. Causes of bilateral humerus proximal end fractures include convulsions caused by electric shock, epilepsy, alcohol deprivation and hypoglycemia that commonly cause sudden and hyper-muscle contractions. While bilateral humerus proximal end fractures are usually accompanied by shoulder dislocations, our cases resulted from simple falls caused by high energy traumas without being unconscious. In this study, two cases, which developed bilateral humerus proximal end fractures as a result of simple fall, were examined in the light of literature.
