Use of an end cap is recommended if bony ingrowth into the
proximal end of the nail is of concern. Also, for reverse
oblique intertrochanteric and high subtrochanteric fractures,
the nail should sit slightly proud of the greater trochanter to
provide an added point of fixation. If the nail has been
overinserted, it should be extended by the use of an end cap
of appropriate length.
The end cap for the Titanium Trochanteric Fixation Nail
System is cannulated and can be inserted over a guide wire.
Place a 3.2 mm guide wire through the incision and into the
top of the nail. Select the appropriate end cap and slide the
end cap over the guide wire and into the top of the nail.
Place the 11 mm cannulated hexagonal socket over the
guide wire and onto the external hex of the end cap. Use the
11 mm ratchet wrench to tighten the end cap. The top of
the end cap should protrude slightly from the top of the
trochanter when fully seated.
The 5.0 mm flexible hexagonal screwdriver, the 5.0 mm
hexagonal screwdriver or the 5.0 mm hexagonal shaft and
ratchet wrench may also be used to insert the end cap with-
out the use of the guide wire.
