Reconstruction Plates, 3.5 mm





- Discussion:
    - these plates are used with 3.5 mm cortex screws;
    - their main application is for use with pelvic and acetabular frx;
    - they may be also used in fractures of the distal humerus (dorsolateral
          apect), the clavicle, and the calcaneus;
    - reconstruction plates have notches alongside the plate, which enables
          bending in three demensions;
    - bending more than 15 deg at any one site should be avoided;
    - note that aready low stiffness of the plate is further diminished by
          bending, & if strong curvature is needed, consider a prebent plate;
    - oval holes permit some self compression if the screw holes are placed
          eccentrically;
    - holes accept 4.0 mm cancellous bone screws if the plate is placed over
          cancellous bone;
    - screws can be inserted at an angle of approx 25 deg longitudinally and
          7 deg sideways;
    - available in 5 to 22 holes, and 58 mm to 262 mm
    - thickness 2.8 mm
    - width 10 mm
    - hole spacing 12 mm;
