50岁男性,外伤后致胫腓骨中1/3骨折,手法复位后,长腿石膏管型外固定。4周后,石膏管型于膝部有折断,未给处理,3个月后。X线片复查见骨折略有移位,骨折线清晰。

该患者下一步的处理是

C.切开复位植骨内固定加长腿石膏外固定

D.切开复位植骨及长腿石膏管型外固定

E.更换长腿石膏管型,继续外固定

答案

参考答案:E

解析:[解题思路] 骨折后,超过一般愈合所需时间尚未愈合,X线片示骨端无硬化者为迟延愈合。分析此例的原因,伤后4周时石膏管型折断,使骨折固定不确实之故。下一步处理是更换长腿石膏,除去造成迟延愈合的原因,继续固定治疗。
[命题规律] 考察“迟延愈合的原因、诊断和处理”。必须掌握。

In ancient times the most important examinations were spoken, not written. In the schools of ancient Greece and Rome, testing usually was made up of saying poetry aloud and giving speeches.

In the European universities of the Middle Ages, students who were working for advanced degrees had to discuss ques­tions in their field of study with people who had made a spe­cial study of the subject. This custom exists today as part of the process of testing candidates (应试者) for the doctor’s de­gree.

Generally, however, modem examinations are written. The written examination, where all students are tested on the same questions, was probably not known until the nineteenth century. Perhaps it came into existence with the great increase in population and the development of modem industry. A room full of candidates for a state examination timed exactly by electric clocks and carefully watched over by managers, looks like a group of workers at an automobile factory. Certainly, during examinations teachers and students are expected to act like machines.

One type of test is sometimes called an “objective” test. It is intended to deal with facts, not personal opinions. To make up an objective test, the teacher writes a series (一系列)of ques­tions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like answers to students who have not learned the material properly.
