Fractures in children differ from those in adults. Because the anatomy, biomechanics, and physiology of a child's skeleton very differ from those of an adult, orthopedic surgeons frequently see differences in the pattern of fractures, the problems of diagnosis, and the method of treatment. So the present study is an clinical analysis of 622 cases of children's fractures under the age of 18 years, who were treated at the department of orthopedic surgery, Presbyterian Medical Center for the past 9 years from 1973 to 1981. Results obtained are as follows: 1. The peak age was 5. 2. The incidence in male was 2 times higher than in female. 3. The most common cause of fractures was traffic accident (65.6% of all cases). 4. The fracture in femur was most common (17.7%). 5. The most common injury combined with fracture was head injury (40.3%). 6. Among the joints elbow was most commonly injuried. 7. The incidence of epiphyseal injury was 10.3%. 8. The most common type of epiphyseal injury by Salter & Harris classification was type II and it's incidence was 57.8% of all epiphyseal injury. 9. 83% of all fractures were conservatively treated. 10. The incidence of complication of all cases was 8.5%.
