Proximal Femoral Fractures (PFF) represent a global public health burden as more than 10 million cases per year are globally reported. Kyle 3 and 4 or AO/OTA 31A2 pertrochanteric fractures account for 10%-15% of all PFF. This specific fracture pattern is characterized by intrinsic mechanical instability as a result of the presence of a detached greater trochanter fragment and is usually treated using a Cephalomedulary Nail (CMN). However, the unstable greater trochanter fragment makes the insertion of the CMN guide wire challenging. Consequently, the authors developed a surgical technique allowing for both stable greater trochanter fragment stabilization and easier CMN guide wire insertion to avoid fracture dislocation and fragment collapse. The aim of this surgical technical note is to describe this procedure basically allowing fracture simplification from unstable to stable, so that this complex PFF pattern can be approached in a structured manner with predictable results in terms of fracture reduction quality and implant position accuracy, even by junior surgeons.
