DCP, 3.5 mm Applied as a Self Compression Plate



- See: DCP 3.5 mm Applied as Self Compression Plate w/ Lag Screw Thru Plate

- Discussion:
    - effect of self compression is used for axial compression of short oblique, or transverse frxs of for example, the forearm, clavicle, and 
         pelvis (tension band plating);
- Prerequisites:
    - plate is contoured to the bone, and in transverse fractures is slightly over bent;
    - axial compression by one or more load screws;
- Technique:
   - fracture is reduced;
   - contoured plate is applied to the bone with the middle portion placed over the fracture, and held with reduction forceps;
   - in plate hole adjacent to the fracture, the first screw hole is drilled using the 2.5 mm drill bit for the 3.5 mm cortical screw;
        - screw is inserted, but not fully tightened;
   - plate is pulled toward the fracture to place the first screw in the eccentric position;
   - second screw hoel is prepared in the plate hole adjacent to the frx in the opposite fragment;
        - yellow (load) DCP drill guide is placed in the plate hole with arrow pointing toward the fracture;
   - thread hole is tapped w/ 3.5 mm tap and the cortical screw is inserted;
   - tightening of the two screws produces axial compression
   - additional load screw may be placed if necessary;
   - in next plate hole, the yellow DCP guide, 3.5 mm is positioned w/arrow towards the fracture;
   - hole is drilled with the 2.5 mm drill bit;
   - hole is tapped;
   - 3.5 mm screw is inserted until the screw head reaches the plate;
   - before the screw is fully tightened, the screw next to it must be loosened to allow for further compression;
   - after tightening of this last screw, loosened screw can be retightened
