Opening the Medullary Canal
Click on image for enlarged view
Make a longitudinal incision proximal to the greater trochanter. Either
the 11.0 mm Cannulated Cutter or the awl can be used to open the
medullary canal.
If the 11.0 mm Cannulated Cutter is used, assemble the 4.0 mm
Centering Pin in the Universal Chuck with T-Handle. Place the tip of
the pin at the correct entry point. Rotate the centering pin to
penetrate the medullary canal. Verily placement with image
intensification. Remove the universal chuck.
Pass the 11.0 mm Cannulated Cutter and Protection Sleeve over the
centering pin. Rotate the cannulated cutter and open the medullary
canal to a minimum depth of 5 cm. (Image intensification may be
required.) When the canal is penetrated, fix the centering pin in the
cannulated cutter by tightening the setscrew at the base of the handle.
Remove the cannulated cutter/centering pin assembly.
If the awl is used, place its tip at the correct entry point, and turn it
to open the medullary canal.
Note: For pseudarthroses or hypertrophic nonunions, use the hand
reamers sequentially to open the canal.
