Basic epidemiological data can provide estimates when discussing disease burden and in the planning and provision of healthcare strategies. There is little quantitative information in the literature regarding prevalence of traumatic injuries from developing countries.


The aim of the current preliminary study was to reveal the prevalence and age and gender distribution of various traumatic injuries in a tertiary referral orthopedic hospital in Iran.


In a prospective descriptive study, all traumatic injured patients attending the Orthopedic Trauma Unit of our center in a five year period were included. Demographic details, the cause of injury, injury classification and treatment were recorded. For each of the five-year age groups and each gender we calculated the numbers with fractures, dislocations, soft tissue injuries, ligamentous injuries and lacerations and derived average age and gender-specific prevalence as well as seasonal variations.


A total of 18890 adults were admitted, 13870 (73.4%) males and 5020 (26.6%) females. There were 8204 (43.4%) fractures. The male fracture age distribution curve was unimodal and there was a detectable bimodal pattern in females. Under 65 years males are 3 times more likely to sustain a fracture than females which decreases to equal risk over the age of 65. The most common fracture site was distal radius/ulna (13.8%), followed by tibial diaphysis (8.8%), proximal femur (7.8%), finger phalanges (6.4%), metacarpals (6%) and metatarsals (5.9%). There were seasonal variations in fracture incidence with peaks in February, March and October. The least number of fractures occurred in June.


The risk of traumatic injuries is higher among specific age groups with different patterns emerging for men and women. Thus, the descriptive epidemiology will provide useful information for treatment or injury prevention strategies, resource allocation, and training priorities.
