Properties of Titanium;
- Discussion:
- is used for same indications as DCP, but the improved design offers additional advantages;
- undercut plate holes: undercut at each end of plate hole allows 40 deg tilting of screws both ways along the long axis of the plate;
- lag screw fixation of short oblique fractures is thereby possible;
- screws can be tilted 7 deg from the transverse plane;
- before applying a LC-DCP, the plate must be contoured or prebent & fracture anatomically reduced;
- LC-DCP, 4.5 mm, is fixed to bone with 4.5 mm cortex screws and 4.5 shaft screws, or in end holes with 6.5 mm cancellous bone screws;
- 4.5 mm screws can be inserted in 3 different positions (neutral, load, and butress);
- for this purpose special drill guides have to be used, either LC-DCP drill guide, 4.5 mm, or the universal drill guide, 4.5 mm;
- Narrow LC-DCP, 4.5 mm in Pure Titanium:
- designed for use on the tibia, but may be used on the radius or ulna in a large patient;
- this plate may function as a neutralization, tension band, or butress plate, as desired;
- it is fixed with 4.5 mm titanium cortex screws and, if located over cancellous bone, with 6.5 mm titanium cancellous bone screws;
- available with 2-16 holes
- thickness 4.6 mm
- width 13.5 mm
- hole spacing 18 mm
- hole length 8.5 mm;
- Broad LC-DCP, 4.5 mm in Pure Titanium:
- designed for use on the femur and for pseudoarthrosis of the humerus;
- available in 6-18 holes (staggered to prevent fissuring)
- thickness 6 mm
- width 17.5 mm
- hole spacing 18 mm
- hole length 8.5 mm;
