A 26 mm 4.5 mm cortex screw is inserted using routine technique parallel to the growth plate through each stab incision. The screw is not tightened yet and the screw head should protrude slightly over the skin surface.
Note: the thread hole is a blind hole so it should be drilled to a depth of approximately 30 mm.
Note: the procedure can also be performed with 3.5 mm cortex screws. However these screws are more difficult to remove, especially with hex design of the propulsion device in the screw head, because of potential failure.
