**4.1 Preoperatively**

A close collaboration and clear communication with the anaesthetist and the other members of the team are hugely important, as the preparation of the patient is paramount. The patient is positioned in Lloyd Davis with attention to avoiding common peroneal nerve injury/femoral nerve neuropraxia or lower limb compartment syndrome. The use of the correct retractor (i.e. Greys, Bookwalter) will also help in gaining an optimal access to the pelvis, but also to the right and left upper quadrants.
