Mount aiming arm and insert locking screw
Attach the Aiming Arm for Spiral Blade Locking (357.116) to
the insertion handle. Insert the turquoise triple trocar assem-
bly (Protection Sleeve 11.0/8.0 (357.118), Drill Sleeve 8.0/4.9
(357.097) and Trocar
4.9 mm (357.098)) through the
cranial hole of the aiming arm and, after a stab incision, to
the bone. Remove the trocar.
Drilling, length measuring, and insertion of the Locking Screw
6.0 mm are performed as described in steps 12 and 13 on
pages 13 and 14.

Insert double-sleeve combination
Insert the pink double-sleeve combination (Protection Sleeve
15.0/13.0 (357.123) and Drill Sleeve 13.0/3.2 (357.124))
through the caudal hole on the aiming arm. Make a stab
incision and advance the combination to the lateral cortex.
The spiral blade locking option with one Spiral Blade
(450.882–892) and one Locking Screw
6.0 mm
(450.862–872) is used for patients with an osteoporotic bone
structure and/or extensive and complex supra-condylar
comminuted fracture areas. The increased purchase area of
the blade provides an optimized load distribution in the
condyles and improves fixation of the distal fragment thus
decreasing the risk of nail protrusion into the knee joint.
Perform steps 1 to 10 as described on pages 4 to 12.
