骨科英文书籍精读（320）｜胫骨棘骨折（3）
我们正在精读国外经典骨科书籍《Apley’s System of Orthopaedics and Fractures》，想要对于骨科英文形成系统认识，为以后无障碍阅读英文文献打下基础，请持续关注。
中国十大名师之一赖世雄老师说过，学习英语没有捷径，少就是多，快就是慢。不要以量取胜，把一个音标、一个单词、一段对话、一篇文章彻底搞透，慢慢积累，你会发现，你并不比每天走马观花的输入大量英文学的差。
Treatment
Under anaesthesia the joint is aspirated and gently manipulated into full extension. Often the fragment falls back into position and the x-ray shows that the fracture is reduced. As long as the knee extends fully, small amounts of fragment elevation can be accepted.
If there is a block to full extension or if the bone fragment remains displaced, operative reduction is essential. The fragment – often larger than suspected – is restored to its bed and anchored by small screws, taking care to avoid the physis.
After either closed or open reduction, a long plaster cylinder is applied with the knee almost straight; it is worn for 6 weeks and then movements are encouraged.
The outcome is usually good and full movement regained; there may be some residual laxity on examination, but this rarely causes symptoms.

治疗
在麻醉下，关节被吸入，并轻轻地伸开。通常碎片落回原位，x光片显示骨折缩小。只要膝盖完全伸展，少量的碎片抬高是可以接受的。
如果完全伸展受阻或骨碎片仍然移位，手术复位是必要的。碎片——通常比怀疑的要大——被恢复到床上，用小螺丝钉固定，小心避开物理损伤。
无论是闭合复位还是开放复位，都要在膝盖几乎伸直的情况下敷上一个长的石膏筒，戴上它6周，然后鼓励活动。
结果通常是好的，完全恢复运动；检查时可能有一些残余的松弛，但很少引起症状。
