Instrument
360.255 Measuring Device for Reaming Rod for TFN
Using image intensification, ensure that fracture reduction
has been maintained. Insert the 2.5 mm reaming rod with
olive ball tip into the medullary canal to the desired insertion
depth.
Ream in 0.5 mm increments and advance the reamer with
steady, moderate pressure. Do not force the reamer. Partially
retract the reamer often to clear debris from the medullary
canal.
Ream to a diameter at least 1.0 mm greater than the nail
diameter as determined by surgeon preference.
After reaming, remove the reaming assembly, leaving the
reaming rod in place.
Note:
The trochanteric fixation nail can be passed over the
2.5 mm reaming rod, with olive ball tip, if used. No reaming
rod exchange is required.
Nail length may be determined by using the reaming rod
measuring device and a 950 mm reaming rod or guide rod.
Insert the reaming rod to hold fracture reduction. Position
the image intensifier over the distal femur and take an image
to confirm reaming rod insertion depth. Pass the reaming
rod measuring device over the proximal end of the reaming
rod and through the incision to the bone. Read nail length
directly from the measuring device.
