<strong>Ostheosynthesis</strong> <strong>cannulated</strong><br />
<strong>screw</strong> <strong>for</strong> <strong>small</strong> <strong>fragments</strong>.
V17 Protocol (Phalanx fracture)<br />
1. Fracture reduction<br />
a<br />
b<br />
a<br />
b<br />
Reduce the fracture and hold with the<br />
reduction clamp.<br />
Measure <strong>screw</strong> length from the reduction clamp.<br />
b<br />
2. K-wire insertion<br />
a<br />
a Place the K-wire guide into the barrel of the<br />
reduction clamp.<br />
b<br />
b<br />
Insert a 0.7mm K-wire and secure it into the<br />
opposite cortex<br />
3. Screw insertion<br />
c<br />
a<br />
b<br />
c<br />
a<br />
Remove the K-wire guide from the barrel.<br />
Slide the appropriate length <strong>screw</strong> and driver over the wire.<br />
Drive the <strong>screw</strong> through the barrel of the reduction clamp<br />
b<br />
4. Compression<br />
a<br />
a Drive the <strong>screw</strong> until its head is flush with the near<br />
cortex .<br />
b Remove the K-wire and reduction clamp .
V23, VC30, VC35 Protocol (Scaphoid fracture)<br />
b<br />
a<br />
1. K-wire insertion<br />
a<br />
Reduce a displaced fracture.<br />
b Per<strong>for</strong>ate the two cortex with a second k-wire, that will guide the positionning<br />
of the <strong>screw</strong> and avoid any risk of <strong>fragments</strong> rotation.<br />
At that point, the distal extremity is at the level of the distal.<br />
2. Measure<br />
It is recommended that fluoroscopy is used to confirm drill depth and <strong>screw</strong> length<br />
3. Drilling<br />
b<br />
b<br />
a<br />
a<br />
b<br />
Place the K-wire gauge<br />
on contact with the<br />
proximal cortex .<br />
Measure the <strong>screw</strong> lenght.<br />
a<br />
b<br />
a<br />
Introduce the appropriate drill<br />
over the guide wire .<br />
Screw lenght can also be checked<br />
directly from the drill, as soon as<br />
contact with the opposite cortex is<br />
made and be<strong>for</strong>e per<strong>for</strong>ating it.<br />
4. Countersink 5. Screw insertion<br />
a<br />
a<br />
a<br />
Prepare the external cortex with<br />
the <strong>cannulated</strong> countersink<br />
through the cartilage so the<br />
<strong>screw</strong> head will be flush.<br />
a<br />
The two K-wires stil in place,<br />
insert the <strong>screw</strong> with the<br />
<strong>cannulated</strong> <strong>screw</strong>driver.<br />
6. Compression<br />
a<br />
a<br />
Drive <strong>screw</strong> until head is<br />
flush with near cortex.<br />
The <strong>screw</strong> head must not go past<br />
the cartilage.<br />
b<br />
Remove the K-wires.
Illustrations <strong>for</strong> in<strong>for</strong>mation.<br />
The drill, countersink and <strong>screw</strong>driver<br />
shaft have a color coded ring that<br />
corresponds to the <strong>screw</strong> diameter it<br />
serves.<br />

Further in<strong>for</strong>mation<br />
The K-wire guide GB 070 is to be used<br />
exclusively with the V17.<br />
The good lenght <strong>screw</strong> can be checked with the<br />
K-wire gauge JD 000.<br />
K-wire diameter can be checked with the<br />
K-wire diameter gauge PB 000.<br />
