357.412 Awl for TFN
Place the 17.0 mm cannulated drill bit into a power drill. Pass
the drill bit over the guide wire and through the protection
sleeve to the bone. Drill to the stop.
Note:
If the fracture line runs through the entry point for the
nail, care must be taken to remove the bone on the medial
fragment to create a path for the nail and prepare an ade-
quate opening for the proximal end of the nail. Do not
plunge the drill bit through the fracture as this may displace
the fracture and cause the fracture to be fixed in varus.
When the 17.0 mm drill bit is removed, the 3.2 mm guide
wire may be captured and removed simultaneously. If the
guide wire remains in the bone, remove it by hand.
Dispose of the guide wire. Do not reuse.
Note:
The cannulated reverse awl may also be used to open
the canal or expand the opening created by the 17.0 mm
drill bit. Use the tissue protector to spare the soft tissues.
Place the awl over the guide wire and to the bone. Use a
twisting motion to advance the awl. As with the cannulated
drill bit, take care not to plunge the awl into the fracture site
because this may displace the fracture and cause the fracture
to be fixed in varus. Take care to remove the bone on the
medial segment of the fracture to prepare an adequate
opening for the proximal end of the nail.
