SURGIcAL TEchNIQUE FOR „Y“-TYpE LIGhT TROchANTERIc NAILING

1 PreoPeraTiVe Planning

Preoperative X-ray of the uninjured distal femur is used to
estimate proper nail diameter, nail length, and CCD-angle
(caput-collumdiaphyseal angle).

Fluoroscopic control is advised.
The image intensifier must be in a standard position for ap
and lateral view.

! Numbers in brackets after instrument names refer to the list
number in the instrument tray.

Pay special attention, important step.

2 ASSEMBLING OF ThE INSTRUMENTS

Attach the intramedullary nail to the radiolucent aiming arm (1) with
the nail adapter screw (6). Secure the nail with the 10 mm hex-
agonal screwdriver (16, 18). Depending on the CCD angle of the
implant (125°/130°/135°) mount the correct aiming arm
attachment (2, 3,4) with the aiming arm fixing screw (5).

! Drive the fixing screw into the nail, but the tip of the screw
should not hinder the rotation of the dynamic screw.

3 Put into the dynamic screw

hole the yellow soft tissue protector (24) and reamer (33).
Put into the distal hole the green soft tissue protector (26),
drill sleeve (27) and 4 mm spiral drill (28).
