LC-DCP

DCP

Bone loss observed beneath a full-contact plate

Reduced bone loss beneath a limited-contact plate

Plates

DCP (Dynamic Compression Plate)DCP plate hole– Incorporates an incline in the hole that converts screwcompression into plate translation and compression of thebone fracture

– Accepts conventional screws that may be placed in eitherload or neutral positions, depending on whether interfragment compression is desired (see Universal DrillGuide Technique on page 8 for more detail)

– Allows 25° of longitudinal screw angulation and 7° oftransverse screw angulation

LC-DCP plate hole– The dynamic compression unit (DCU) hole is symmetricaland provides bidirectional compression

– Allows 40° of longitudinal screw angulation and 7° oftransverse screw angulation

– Accepts cortex screws that may be placed in either load orneutral positions, depending on whether interfragmentcompression is desired (see Universal Drill Guide on page8 for more detail)

– Centrally located hole at one end for metaphyseal fracturerepair

Uniform stiffness– Allows smooth contouring of the plate to the bone– Protects plate from localized high bending stress, becauseof the even distribution of stresses over a long distancealong the plate

LC-DCP (Limited Contact Dynamic Compression Plate)Grooved undersurface– Provides limited contact between the plate and bone, reducing the chance for temporary porosis under the plate

– Allows periosteal callus formation at the fracture site

LCP (Locking Compression Plate)– Locking screws create a fixed-angle construct, resulting inangular stability

– Tapered end for submuscular plate insertion, reducing tissue trauma

– Limited-contact plate design reduces plate-to-bone contact, protecting vascularity

LCP plate holes– Dynamic compression unit (DCU) hole allows 40° of longitudinal screw angulation and 7° of transverse screwangulation

– Combi-holes allow placement of cortex screws on oneside or locking screws on the opposite side of each hole

Screws

Cortex screws– Used for bicortical fixation in diaphyseal bone– Self-tapping screws are standard in all sets– Non-self-tapping screws are also available in 1.5 mm and2.0 mm (hexagonal drive)

Locking screws– Used with the locking compression plate (LCP)– Conical, double-lead machine thread on the head locksinto threaded combi-hole or stacked combi-hole in theplate

– Create a fixed-angle construct– Stardrive recess is designed to provide improved torquetransmission to the screw, while retaining the screw with-out the use of a holding sleeve


A

B

Screw fixationBicortical cortex screw fixation compresses a plate to thebone, creating friction between the plate and bone to maintain stability. Bicortical screws require two cortices of fixation to achieve stability (Figure A).

Locking screws provide stability and load transfer due to thethreaded connection between the plate and screw, withoutcompression of the plate to the bone (Figure B).

Note: If a combination of a cortex screw and locking screwsis used, a cortex screw should be inserted first to pull theplate to the bone. If a locking screw is used first care shouldbe taken to ensure that the plate is held securely to the boneto avoid spinning of the plate about the bone.

Warning:Synthes implants and instruments are manufactured withproprietary processes that produce superior products tothose created by conventional manufacturing processes.Though other companies may be able to estimate the Synthes general product design, Synthes product dimensionsare proprietary. The precision design of Synthes products isvery important for long-term product function and optimalfit between implants.

Only the finest quality materials are used to manufactureSynthes implants. The metals Synthes uses have been scientifically proven to be of the best biocompatibility andquality available today.

With these features and qualities, the mixing of Synthes implants with the implants from other companies is not rec-ommended. The overall performance may be compromiseddue to differences in design, chemical composition, mechani-cal properties, and quality.

Given these qualities are trade-secret, no competitor of Synthes can make a genuine claim “the same as Synthes”.Combining implants from other companies with Synthes implants could reduce product performance. Consequently, itis strongly recommended to not mix parts from differentmanufacturers.


Neutral

Compression (load)

Universal Drill Guide Technique

Compression (load) positionCompression is achieved by placing the universal drill guidein the eccentric position, and maintaining the drill guidebody above the plate as shown.

Neutral positionNeutral position is achieved by placing the universal drillguide in the eccentric position, and compressing the drillguide body into the hole.

Note: For illustrative purposes, a combi-hole has been depicted. The same methodology applies to LC-DCP andDCP holes.


Featured Instruments

312.140 Double Drill Guide 1.5/1.1 For use with 2.0/1.5 LC-DCP plates and

2.0/1.5 LCP plates (1.5 mm cortex screws)

Compression is achieved by placing the drill sleeve in the eccentric position, while the neutral position is achieved byplacing the drill sleeve in the center of the plate hole.

312.181 Double Drill Guide 2.4/1.8, with CenteringCollar

323.200 Universal Drill Guide 2.0 For use with 2.0/1.5 LC-DCP plates,

2.4/2.0 LC-DCP plates and2.0/1.5 LCP plates(2.0 mm cortex screws)

323.202 Universal Drill Guide 2.4 For use with 2.4/2.0 LC-DCP plates and

2.4 LCP plates (2.4 mm cortex screws)

The universal drill guides are the only drill guides which function in all Synthes plate holes.

When a cortex screw is used, a universal drill guide should beused to guide the drill bit. If the screw is intended to achieveinterfragment compression, the universal drill guide shouldbe placed in the load position. If the screw is intended tohold the plate, the universal drill guide should be placed inthe neutral position.


Featured Instruments

– For use with 2.0 mm locking screws – Threads into locking plate for correct

alignment of locking screw with platehole

– Centers drill bits to ensure perpendiculardrilling

– Permits proper mating of locking screwin the threaded portion of the combi-hole

alignment of locking screw with platehole

– Centers drill bits to ensure perpendiculardrilling

– Permits proper mating of locking screwin the threaded portion of the combi-hole

Technique tip: To prevent cross-threading, turn the LCP drillsleeve counterclockwise until it is properly engaged (a slightclick may be apparent), then turn it guide clockwise.

Note: The LCP drill sleeve can also be used intraoperativelyas a reference for visualizing the projection of a lockingscrew in a given hole.

511.777 Torque Limiter, 0.4 Nm, with AO/ASIFQuick CouplingFor use with 2.0 mm locking screws

When inserting a locking screw, a torque limiter is used toensure the appropriate amount of torque is applied, to mini-mize the risk of a locking screw backing out of the plate orcold-welding the screw to the plate.
