During recent years, skateboards have become increasingly popular in Denmark. According to trade reports, skateboards for a two-figure million Danish crowns are sold annually and the number of users is estimated to be 300,000. During the summer period from 1.5 1988 to 31.10 1988, 71 skateboard injuries were registered in the Casualty Department, Gentofte Hospital. The average age of the patients was 14 years and a 90% predominance of boys was observed. 31% of the injured persons had fractures. The mechanism of injury appears to be an averting movement when the balance is suddenly lost and more than 50% of the injuries and more than 80% of the fractures were localised to the upper limbs. More than 8% of the injured patients required hospitalisation. Only 15.2% of the patients registered here had used any form of protective equipment. Possible prophylaxis includes protective equipment and restricted rinks for skateboard enthusiasts.
