===Support pointsPin positions===The pins should be at least 2 cm apart on frontal projection, and have <10° angle compared to each other.<ref name=ToplicMellner>{{cite web|url=http://www.ortobas.se/lih-spikning/|title=LIH-spikning (Hansson Pin)|author=Marsel Toplić, Carl Mellner|website=ortobas.se}}</ref> The inferior pin should be inserted at the level of the minor trochanter.<ref name=ToplicMellner/>
For proper support, both pins should have support by the subchondral plate and the lateral cortex. In addition, the middle of the inferior pin should be supported by the medial cortex, and the middle of the posterior pin should have support from the medial cortex, with less than <5 mm distance from subchondral bone.<ref name=ToplicMellner/>
