The Synthes® technique guide for the locking compression proximal femoral plate advises that the plate is reduced on to the femur using a threaded cannulated conical screw that is subsequently exchanged for a locking screw.1 The conical screw is not necessary if a locking screw is inserted with a Synthes® (Welwyn Garden City, AL7 1LG) 8.0mm large fragment wrench placed under the screw head (component 314.210; supplied on the tray), taking care not to damage the locking screw thread. This prevents screw/plate engagement, lagging the plate on to the bone. After inferior screw insertion, wrench removal allows the superior screw to lock into the plate. This technique can be modified for any locking plate system.
