Plate Guide


DCP (Dynamic Compression Plate) DCP Plate Hole

DCP PlateDCP Plate Hole 
  • Incorporates an incline in the hole that converts screw compression into plate translation and compression of the bone fracture
  • Accepts cortex screws that may be placed in either load or neutral positions, depending on whether or not interfragment compression is desired (see Universal Drill Guide for more detail).
  • Allows 40° of longitudinal screw angulation and 7° of transverse screw angulation



LC-DCP (Limited Contact Dynamic Compression Plate) Grooved undersurface

 LC-DCP Plate
  • Provides limited contact between plate and bone, minimizing the chance for temporary osteoporosis under plate
  • Allows for periosteal callus formation at the fracture site



LC-DCP Plate HoleLC-DCP Plate Hole
  • The dynamic compression unit (DCU) is symmetrical and provides bidirectional compression
  • Allows 80° of longitudinal screw angulation and 14° of transverse screw angulation
  • Accepts cortex screws that may be placed in either load of neutral positions, depending on whether interfragment compression is desired (see Universal Drill Guide for more detail)





Plate Comparison (for Uniform Stiffness section)Uniform Stiffness
  • Allows smooth contouring of the plate to the bone
  • Protects plate from localized high bending stress





LCP (Locking Compression Plate)

 LCP Plate
  • Locking screws create a fixed angle construct, resulting in angular stability 
  • Tapered end for submuscular plate insertion, minimizes tissue trauma
  • Limited-contact plate design reduces plate-to-bone contact, protecting vascularity

LCP Plate Holes

Combi holes allow placement of standard cortex and cancellous bone screws on one side or threaded conical locking screws on the opposite side of each hole


        A. Threaded hole section for locking screws
        B. Dynamic compression unit (DCU) hole
            section for standard screws
        C. Locking screw in threaded side of plate 
        D. Cortex screw in compression side of
            plate hole

  • Dynamic Compression Unit portion of hole allows 40° of longitudinal screw angulation and 14° of transverse screw angulation


Stacked Combi Holes accept either cortex, cancellous, or locking screws.

Screw Guide


Cortex Screws

 Cortex Screw
  • Used for bicortical fixation in diaphyseal bone
  • Self-tapping screws are standard in all sets
  • Non-self-tapping screws are also available



Cancellous Bone Screws

 Cancellous Screw
  • Used for fixation in poor quality or metaphyseal bone
  • Deeper threads and coarser pitch maximizes the surface area of the threads that is in contact with the bone, thereby increasing the screw's holding power in this softer bone.



Locking Screws

 Locking Screw
  • Used with the Locking Compression Plate (LCP)
  • Conical, double-lead machine thread on head locks into threaded Combi-hole in the place
  • Creates a fixed-angle construct
  • Large core diameter provides improved bending and shear strength
  • StarDrive recess provides torque transmission to the screw, while retaining the screw without the use of a holding sleeve 



Screw Fixation

 Bicortical Fixation

Uni Corticalfixation

Bicortical cortex screw fixation is the traditional method of compressing a plate to the bone. Friction between the plate and bone maintains stability. Therefore, bicortical screws require (2) cortices of fixation to achieve stability (Image A).

Unicortical locking screws provide stability and load transfer at the near cortex due to the threaded connection between the plate and screw. Screw stability and load transfer are accomplished at two points along the screw: at the locked screw head and at the near cortex (Image B).
