Select screw angle
Under AP image intensification,
lay a guide wire on the anterior
thigh along the femoral neck
axis. Adjust the angle of
the guide wire until it is
perpendicular to the fracture.
This will allow the surgeon
to place the screws perpen-
dicular to the fracture for
optimal fracture compression.
Hold the wire in this position.
With the aiming arm oriented
laterally, gently move the
instrument assembly up or
down along the insertion
site until the guide wire
corresponds to one of the
four Miss-A-Nail angles
etched on the aiming arm.

Determine screw angle. In this example, the
anterior guide wire corresponds to the 120°
Miss-A-Nail angle.
Verify angle in AP view

OCKING
Securely thread the Miss-A-Nail
jig into the aiming arm at
this angle. Insert the 2.8 mm
wire sleeve into the superior
bushing of the jig and use
it as a pointer to verify the
angle and dummy nail
insertion depth under image
intensification.
