家长骑自行车带孩子是很普遍的事。小孩不老实,把脚伸到车条里的事也时有发生。伤后脚脖了上部有点肿,外皮有点轻微擦痕,看起来还能活动,家长往往以为不要紧,但孩子却不能下地走路了。这是为什么呢? 人的小腿骨是由胫骨和腓骨两条等长的管状骨并列组成的,胫骨粗大在内前部,腓骨细长在后外部,两骨下端连着踝关节。当孩子脚尖朝里,钻进车轮后,车轮转动时,就把小腿下端带入车条里,这等于把小腿向内撅的动作。直到孩子喊叫疼时,大人才退车把腿解脱出来。

The upper part of the injured neck a little swollen, the skin a little scratches, it seems activity, parents often think it does not matter, but the children can not walk under the ground.

Human legbone is composed of two equal length of the tibia and fibula tubular bone composition, the tibia coarse in the anterior, slender fibular slender external in the lower extremity of the two bones attached to the ankle. When the child toes inward, after drilling into the wheel, the wheel turns, the lower end of the leg into the car, which is equal to the calf inward 动 action. Until the child shouts pain, adults get rid of the leg to get rid of.
