==Planning==
Frontal and lateral projections.
==Post-operative evaluation==
[[File:X-ray of Hansson pins with contact points.jpg|thumb|Support points]]
The pins should be at least 2 cm apart on frontal projection, and have <10° angle compared to each other.
===Support points===
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>{{cite web|url=http://www.ortobas.se/lih-spikning/|title=LIH-spikning (Hansson Pin)|author=Marsel Toplić, Carl Mellner|website=ortobas.se}}</ref>
