Ala Hook (Use for rib-to-ilium construct)
Make a four centimetre longitudinal incision just lateral to
the posterior cranial iliac spine. Identify the posterior third
and middle third of the iliac crest. Make a one centimetre
transverse incision in the mid substance of the apophysis
with equal layers of cartilage above and below the incision.
Insert the periosteal elevator through the apophyseal incision
to widen it into a tunnel and thread it along the medial corti-
cal surface of the iliac crest. The tip of the periosteal elevator
should be just lateral to the Sacro-iliac joint.
Choose the appropriate Ala Hook (45° or 90°, left or right).
The correct Ala Hook should have the upper end lying medial
to the downward pointed end.
Attach the Extension Connector to the Ala Hook using the
2.5 mm Hex Screwdriver. Ensure the 5.0 mm opening in the
Extension Connector is mated with the Ala Hook.
Use the 5.0 mm Bending Irons (388.911 and 388.922) to
contour the Ala Hook to fit the ilium. Insert the Ala Hook,
pointed end downward, into the apophyseal tunnel using
the Holding Forceps for USS Paediatric Rods

(388.441) over the top of the iliac crest and lateral to the
Sacro-iliac joint.
