广播电视英语短句 第 87 课：骨骼断裂-1

The medical term for a broken bone is a fracture. But there are different kinds of fractures. 骨骼断裂的医学术语是“骨折”。但骨折分为不同的类型。

A single fracture is when a bone is broken in just one place. 单处骨折指的是骨骼仅有一个地方被损伤。

You may have heard the term hairline fracture. This is a single fracture that is very small, like the width of a hair. 你也许听说过“骨裂”这个术语。这是指这个单处骨折非常小，其裂口宽度就和头发丝一样。

A complete fracture is when the bone comes apart. 完全性骨折指的是骨头断开了。

When a bone is broken in more than two places or gets crushed, the name for it is a comminuted fracture. 当一块骨头有超过两个位置的损伤发生，或者骨头碎了，就叫做粉碎性骨折。
