S-mm hole is drilled through an adjacent plate hole using the green (neutral) end of the DCP drill guide. S-mm cortex tap, and the first screw is inserted An eccentric drill hole is made in the opposite fragment using the yellow end of the DCP drill guide, making sure the arrow points to the fracture. Correct placement of the bit can be checked by looking at the lower part of the drill guide. The hole is tapped and the screw inserted. ~ =::-:="'" b Twice as much compressive displacement can be obtained by inserting a second screw by the same technique.
5-mm DCP can also function as a neutralization plate. In this case all the screw holes are drilled centrally through the green, neutral drill guide. The oval holes of the DCP permits screws to be inserted at an angle if required. This may be necessary to avoid a fracture line or a previously placed lag screw (Fig. 32d). Oblique fracture lines should be compressed with a plate screw whenever possible, as this significantly augments the stability of the fixation (Fig. 32c). 0-mm DCP, the technique is the same, using correspondingly smaller instruments and a smaller compressive displacement.
It is virtually impossible to correct malalignment by drilling new holes. This technique is designed to avoid the two most common errors in this type of internal fixation: - Axial malalignment with use of the T plate. This results from eccentric tensile forces that arise when the fracture is compressed before both screws have been -inserted in the T piece of the plate (Fig. 38 b). - Rotational mal alignment with the oblique L plate. This occurs when the delayed insertion of a screw off the long axis of the plate alters the rotational alignment of the bone (Fig.
