Hand dominance and gender in forearm fractures in children.
No published studies have addressed the role of hand dominance in various types of forearm fractures. The present study aims to investigate the effects of the dominant hand and gender in forearm fractures in children and adolescents. In a prospective study, 181 children aged 2-15 years presenting with unilateral forearm fracture were examined over a 6-year period, investigating the role of the dominant hand, fractured side, fractured site, and gender in different types of forearm fractures. Forearm fractures occur more often in boys and are more common on the left side (P = 0.001, 0.029, respectively). Isolated distal radius fracture is more common than distal radius and ulna fracture in right-handed children (P = 0.008). Increases in the number of middle forearm fractures in the dominant hand in left-handed children (P = 0.0056) may be due to mechanisms of injury other than a simple indirect fall or severe injury preventing the use of the dominant hand as a preventive measure. The mean age for boys and girls at the time of forearm fractures was 8.97 and 5.98 years, respectively, which may be attributed to older girls tending not to do as many outside-the-home activities as boys at this age. Overall, forearm fractures are more common in the non-dominant hand, in boys, and in both distal forearm bones.
