Injuries due to different kinds of trauma are one of the major causes of mortality and disability around the world . The World Health Organization (WHO) considered trauma an important issue that merits more attention. Injuries caused by traffic accidents in developing and developed countries are social problems that result in wasting of human and financial resources. Approximately five million people die annually (570 individuals per hour) in accidents that can be prevented . Orthopedic injuries (including soft tissue, muscle, or bone injuries) are the most common injuries in traffic accidents and other types of accidents . Today, orthopedic traumas needing surgery are significantly increasing and impose significant individual and social disabilities, loss of work days and less social activities . Despite abundant epidemiologic data on the nature of such injuries, there are few studies focusing on specific age groups, different types of orthopedic injuries, and/or differences in age, gender and trauma etiology. Because of the geographical location of Guilan province, road situation, frequent rainfall, rural lifestyle, forest homes, mountainous terrain and excessive use of vehicles without safety gear such as motorcycle, tractor, etc., this region is one the most trauma predisposing provinces of Iran .
