PercuFIX Standard Surgical Technique
PercuFIX Surgical Technique for Arthrodesis
1)
2)
A) Direct method
A1) A2)
1) Drill over the two step wires (451-0007)
through both fragments.
3) 4)
2) Measure the screw length with the
direct-reading depth gauge inserted over
the first wire.
A1)Decorticate articular surfaces.
Determine screw length.
A3)
A3) Check for correct positioning and
compression.
A2) Insert PercuFIX screw.
A4)
B) To and For method
A4) Break off the shank ONLY if position
and compression are fully satisfactory.
B1) B2)
3) Remove the first wire (the second wire
is left in place to maintain the synthesis of
bone fragments). Drive in the first screw,
taking care to maintain axial alignment.
Advance the screw until the break-off
groove has been reached (color change
point).
5) 6)
4) Measure the second screw length in the
same way.
B1) Decorticate articular surfaces.
Determine screw length.
B3)
B
A
B3) Hold part A to drive the shank (B) into
the distal fragment.
Hold part B and complete retrograde
insertion by reverse screwing.
B2) Perforate the distal bone fragment with
the wire (451-0007).
B4)
B4) Accurately position the two bone
fragments. Drive the screw into the proximal
fragment until the break-off groove reaches
the cortex of the distal fragment.
Check for correct positioning (cf. A3).
Break off shank (cf. A4).
C) Removal
5) Remove the second wire (while the first
screw maintains the synthesis of bone
fragments), and insert the second screw
as previously described.
6) Assess fixation before breaking off the
shanks. If fixation is not fully satisfactory,
remove the screws and repeat the
procedure.
C1) C1) Use a small gouge to prepare the entry site for the
screw extractor (961-0000)
-Position the screw extractor in line with the axis of the
screw. If necessary, use image intensification to check for
proper alignment
-Turn counterclockwise so that the extractor engages the
counter threads of the screw over 3 mm and then drives the
screw backward.
WARNING : Disengage the screw from the extractor by
rotating CLOCKWISE : the screw must be removed prior to
cleaning the instrument.
