广播电视英语短句 第 87 课：骨骼断裂-5

A doctor sets a broken bone to make sure it is in the correct position. 医生会重新复位断骨以确保其在正确的位置。

Severe breaks may require an operation to hold the bone together with metal plates and screws. 严重的骨折需要进行手术，用金属板或者螺丝钉来续接断骨。

Then, a hard cast may be put around the area of the break to hold the bone in place while it heals. 在治疗过程中，会在断骨周围打上石膏以确保其不移位。

Casts are usually worn for one to two months. 打石膏的时间通常为一到两个月。
