15) Cut the orthosis free and deburr the edges. Ensure that the cut edge at
the foot stirrup runs directly below the ankle joint. This results in the
highest possible supporting surface of the foot stirrup.
16) Transfer the bore holes of the bar and the foot stirrup to the orthosis
shell (see fig.14).
17) Screw the orthotic joints to the orthosis shell.
18) Secure screw connections with Loctite241 (see fig.15).
