Recently in the streets and alleys can see children gathered together, playing a new skateboard, children also compete with each other who play the level of high, boys and girls have. The skateboard uses the body, feet twisting and hand swing to drive the dragon board forward, because of its movement forward look there, such as the dragon and snake general wandering, so the name swim dragon board. Parents are also happy to see children in the outdoors, sweating, not sitting next to the computer. Encourage them to enjoy playing the emerging sports. According to the manufacturer, the skateboard is different from the traditional skateboard, there is greater fun and challenging. It is characterized by the freedom of surfing pleasure, can do a variety of fancy changes in the movement, forward direction at will, the best at turning and drifting. However, because of the difficulty of speed control and balance control, it is more likely to cause children to fall, either forward or backward. Among them, the body to fall backward is likely. Falling backwards in this way is difficult for children to control, and it is easy to land on the back of the elbow joint, and elbow fractures can easily occur. If you wear elbow pads, you can reduce the damage, but it is still very dangerous. If the child falls forward and lands with the hands in a dorsal extension position, the child is prone to a forearm ulnar radius cyanotic fracture. The impact of this injury on children is relatively small, and most children can be treated in the hospital with a cast that has little impact on upper extremity function. Recently, we have noticed an increase in the number of children with this type of injury. Injuries to the elbow, forearm and wrist joints are common. Elbow injuries include supracondylar fractures, intercondylar fractures, and hawkbill fractures of the humerus. Forearm injuries are mostly ulnar radius double fractures, and wrist injuries are mostly distal radius epiphysis fractures. Most children come to the hospital with fractures that are fixed in plaster and have little impact on their long-term function. However, in the case of fractures around the elbow joint, surgery is often required to correct the fracture displacement, and joint stiffness and elbow valgus deformity may still occur in the long term. It is recommended that parents do a good job of protecting their children from fractures if they play with the Dragon Board, and must wear elbow and wrist protection tools. At the same time to wear a good helmet, knee pads, and other professional protective gear. It is best to have professionals to guide children to practice. Parents should guide children to play skateboard to the open, flat, less people, no vehicle passing through the safety of the place, avoiding steps to avoid some accidents. Remind children to play on a flat surface. Younger children are advised not to play with this type of skateboard as much as possible. Good body balance control is required to play skateboarding. Children under eight years old do not have strong body balance control and are therefore discouraged from playing skateboarding. Children are precious, please take care of them.
