Prior to insertion of the guide wires, the plate should be slightly overbent at the level of transverse fracture, so that, when the load screw in the distal fragment is tightened, the medial (trans) cortex is compressed first. This avoids gapping of the medial cortex, which would otherwise occur and result in cyclical motion, leading to excessive strain in the healing tissues, delayed union and fatigue failure of the plate.

The proximal femoral plate is anatomically shaped to match the profile of the upper femur. First, the plate is adjusted optimally to fit the proximal fragment. Through the two attached wire guides, the proximal 2.5 mm guide wires are inserted into the proximal fragment.
