Operative Technique
• Entry point with
One Step Conical Reamer
Alternatively, the 13mm diameter
One Step Conical Reamer for the
9 and 11mm nails or the 15mm
diameter Reamer for the 13 and 15mm
nails may be used for opening the
medullary canal and reaming of the
trochanteric region.
Under image intensifi cation control,
the entry point is made with a
Ø3.2 × 400mm Recon K-Wire which
is attached to the Guide Wire Handle
and advanced into the medullary
canal. Confi rm its placement within
the center of the medullary canal
on A/P and lateral image intensifi er
views.
Note:
The Recon K-Wire used for the
entry point should not be used
again for the Lag Screw insertion.
It is recommended that a new
K-Wire be utilized.
The Recon Protection Sleeve and
Multi-hole Trocar are positioned with
the central hole over the K-Wire.
Note:
The Multi-hole Trocar has a
special design for more precise
insertion of the Ø3.2mm Recon
K-Wire (Fig. 8). Beside the central
hole, 4 other holes are located
eccentrically at different distances
from the center (Fig. 8a) to easily
revise insertion of the guiding
K-Wire in the proper position
(entry point).
When correct placement of the guiding
Recon K-Wire is confi rmed on image
intensifi er views (A/P and lateral),
keep the Tissue Protection Sleeve
in place and remove the Multi-hole
Trocar.
The T-Handle is attached to the
One Step Conical Reamer and hand
reaming is performed over the Recon
K-Wire through the Tissue Protection
Sleeve (Fig. 9).
The Recon K-Wire is then removed
and replaced with the Ø3 × 1000mm
Ball Tip Guide Wire.
