As with any combi-hole the surgeon chooses to use either a locking head 5.0 mm screw (1) or a standard 4.5 mm bicortical screw (2).
Note: choice of locking versus standard screw
If the alignment of the fracture is appropriate and the plate stands a little away from the bone surface, a locking-head screw should be inserted. In this situation, the use of a standard cortical screw will draw the bone to the plate and deform the fracture reduction.
If the surgeon wishes to align the bone to the contour of the plate, a standard cortical screw should be utilized.
