The Hip: Preservation, Replacement and Revision

LC-DCP, 4.5 mm in Pure Titanium



- See:  Synthes Plates and Screws:3.5 MM DCP, LC-DCP   3.5 MM LCP    4.5 MM LCP RECONSTRUCTION PLATE 
    - Dynamic Compression Plates:
    - 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
