- Prone position
The prone position provides access to the posterolateral and posteromedial approaches.
The patient is positioned prone on a radiolucent table with the knee flexed to 20°, padding under the thigh, and the ankle placed over a small bump. It is important to ensure the foot is hanging free over the bump to aid reduction of any displaced posterior fragment.
The image intensifier is positioned on the opposite side of the table, so that the C-arm can be swung underneath the table for lateral imaging.
A tourniquet should always be applied to the thigh but not necessarily be inflated, depending on the surgeon’s preference.
