percutaneous fixation of a scaphoid

舟骨骨折的经皮固定术，

fracture here we're visualizing the

我们将

scaphoid with interrupted fluoroscopy

通过中断透视观察舟骨，

and taking a look at the fracture right

并

through the waist of the scaphoid it is

通过舟骨的腰部观察骨折，

not as well highlighted here as it is in

这里没有像在办公室那样突出显示

the office under regular plain film

在常规平片

x-rays here I'm using a 14-gauge

X 射线下，我使用 14 号

angiocath etre or IV catheter to locate

静脉留置针或静脉导管来定位

the distal pole of the scaphoid this

舟状骨的远端，这

allows me to leave the plastic portion

使我可以将静脉导管的塑料部分留

of the IV catheter in place remove the

在原位，取出

needle and then place k-wire right down

针头，然后放置 k - 将导线向下

through the center of the IV catheter

穿过 IV 导管的中心，

I'll go ahead and drill the wire down

我将继续将导线向下

through the scaphoid to a certain level

穿过舟状骨钻到一定水平，

remove the plastic anja catheter and

取出塑料 anja 导管，

then finish advancing the wire down

然后将导线向下

through the rest of the scaphoid here

穿过舟状骨的其余部分，

I'm going to visualize the placement of

我在这里 将

the wire using interruptive rasca P you

使用中断性 rasca P 可视化导线的放置，您

can see that the wire goes directly down

可以看到导线直接向下

through the axis of the scaphoid and

follow this on interruptive fluoroscopy

也在中断性透视中遵循这一点，

you can see that the drill bit is just

您可以看到钻头刚好

past the fracture remove the drill bit

经过骨折处，取出钻头
