For proximal humerus: Insert the 90° Cannulated LC-Angle Blade Plate over the guide wire. The blade will chisel through a portion of the near cortex and displace a small amount of cancellous bone*. Remove the guide wire.
Place an oblique lag screw through the most proximal plate hole to engage the far cortex. Use 4.5 mm Cortex and 6.5 mm Cancellous Bone Screws to fix the plate to the bone and stabilize the fracture.
* Note: If the plate does not fit flush to the bone, additional cortical hone below the guide wire can he removed with a chisel.
The Inserter/Extractor Handle [332.402] can be used with the Small Slotted Hammer [332.403] to aid insertion. Light mallet blows are recommended in the proximal humerus to avoid over-insertion or disruption of the fracture.
