股骨下1/3骨折可并发()

A.重要动脉损伤

B.重要神经损伤

C.二者均可

D.二者均不可

答案

参考答案:D

解析:

①伸直型肱骨髁上骨折远折端向上移位,近折端向下向前移位,因此近折端容易损伤肱动脉、正中神经。类似的:屈曲型远折端向前移位,近折端向下移位,很少刺破位于关节前面的神经、血管。②股骨下1/3骨折,远折端受腓肠肌牵拉及肢体重力作用,向后方移位,常常损伤胭动脉、胭静脉、胫神经、腓总神经。参阅【2004NOll0】。

Children today would rather read, do housework or even do homework than play outside--- and they get out half as much as their parents did when they were young.

According to a UK study, those growing up during the 1970s and 1980s enjoying more than two hours of outdoor activities each weekday, and nine hours on weekends—whatever the weather is. But their children play outside for just over one hour each weekday, and fewer than five hours on Saturdays and Sundays.

So, the UK started an activity to encourage children to give up 30 minutes of screen time a day to play outdoors.

The Wild Network, born on September 25, 2013, is joined by more than 300 organizations, large or small. It tries to attract children away from television and computer screen and into woods and parks.

It is the biggest ever activity to reconnect children with nature and outdoor activities, and it plans to help improve children’s health.

Suggestions on how to get more time in nature including collecting fruits, camping, watching autumn colour on trees and so on.

This is not the first time the message of less screen, more play has been brought up. Children in the 1980s were encouraged to do the same by BBC TV show Why Don’t You, which encouraged children to “turn off your TV set, and go to do something less boring instead”.
