The cement and accessories portfolioSmith & Nephew offers a full cement and accessories portfolio from bone cement to pulse lavage. To adequatelypromote and sell the cement and accessories portfolio, a thorough understanding of each product is required.Characteristics of bone cementBone cement comes in two parts:1. Powder, or the polymer2. Liquid, or the monomerOnce the powder and the liquid are mixed together, polymerization occurs andan exothermic reaction creates the final, hardened bone cement.The powder component typically consists of the following three materials: The polymer (in the form of one or a combination of the following)- PMMA – Polymethylmethacrylate- MMA/Styrene Copolymer – Methylmethacrylate/Styrene Copolymer- MMA/MA Copolymer – Methylmethacrylate/Methacrylate Copolymer Radiopacifier – Zirconium Oxide or Barium Sulfate Initiator – Benzoyl PeroxideThe liquid component typically consists of the following materials: MMA – Methylmethacrylate Initiator – N-Dimethyl-P-Toluidine Inhibitor/Stabilizer – HydroquinoneCompetitive S&N RALLY PMMABarium SulphateS&N VERSABOND PMMA MMA/MA copolymerZirconium DioxideTMMMA/MA copolymerZirconium DioxideTMPMMA MMA/Styrene copolymerZirconium DioxideBiomet Cobalt HVBiomet Cobalt MVTMDePuy CMWPMMABarium SulphateTMMMA/MA copolymerZirconium DioxideTMPMMA MMA/Styrene copolymerBarium SulphateTMPMMABarium SulphatePMMA MMA/Styrene copolymerBarium SulphateMMA/MA copolymerZirconium DioxideDePuy SmartSet HVDePuy SmartSet MVExactech CemexTMStryker Simplex PTMZimmer Palacos RImportant termsPolymer: Many molecules combined together to form chains or structuresMonomer: Single molecules that will combine with other molecules to form the polymer (the building blocks)Polymerization: A chemical reaction in which two or more molecules combine to form larger molecules orchains that contain repeating structural unitsExothermic reaction: A reaction/process that gives off heat as a product of the reactionRadiopacifier: Component that allows the substance to show up on an X-rayInitiator: Component that starts a chemical reactionInhibitor/Stabilizer: Prevents degradation or uncontrolled recombinations of the polymerConfidential – For internal use only by Smith & Nephew employees and sales force.

How does it work?PolymerizationPolymerization is the reaction that occurs when mixing the powder and the liquid components. The reactionbegins as soon as the liquid wets the powder. The liquid initiator (N-Dimethyl-p-Toluidine) reacts with thepowder initiator (Benzoyl Peroxide) and the monomer and polymer begin to polymerize (join together to createlonger chains) causing the mix to change into a doughy state. Polymerization continues unassisted via anexothermic reaction. Heat is released until the polymerization process is complete.The setting processThere are three aspects to the bone cement setting process. The dough time, or wait time, is the time fromwhen the cement is mixed until it no longer adheres to the moist surgical glove. The working phase, orhandling time, is the amount of time the cement is workable or implantable. Finally, the overall setting time isfrom the moment the powder and liquid components are mixed until the hardening phase is complete.The following are variables that can impact the amount of setting and handling time and must be consideredin surgery: OR Temperature – the warmer the temperature, the faster the cement sets and the shorter the handling time. Chilling the monomer and powder – the colder the temperature, the slower the cement sets. Cooling thecomponents slows the reaction. The reverse happens when the components are warmed. Chemical composition of the cement – the components of the cement and its inherent viscosity affectthe setting process. Every cement is different, and therefore, every cement requires an understandingof its own temperature vs time curves.Time vs temperature characteristics4Note: Lighter shades of blue, green and grey suggest /- 1 min tolerances.

ViscosityViscosity is the relative flow resistance of a material. The viscosity of bone cement affects its handlingcharacteristics, handling time, and penetration of the cement into the cancellous bone. There are threelevels of viscosity in bone cement. Low Viscosity (PalacosTM LV) – Very runny for a longer period of time, like milk. Medium Viscosity (VERSABOND , RALLY MV, Simplex P) – Initially more liquid, but sets up 5 – 8minutes faster than low viscosity, like pudding. High Viscosity (RALLY HV, PalacosTM R) – Reaches a dough state within the first few minutes of mixing,like PlayDoh .The features and benefits of RALLYRALLY is manufactured by Tecres, S.p.A in Verona, Italy. Tecres has 30 years of experience developing,manufacturing, and selling bone cement and accessory products. Smith & Nephew’s goal for RALLY wasto offer 2 different cement options – a cement that is doughy and sets quickly conducive to TKA and acement that takes longer to set up conducive to injecting cement. This further enables Smith & Nephewto offer a solution for more surgical scenarios. Bone cement is an intergral part of the long-term survival ofcemented TJA and the following features and benefits of RALLYcements should be noted:RALLY comes in two viscosities allowing for use in different totaljoint procedures.RALLY has a long-lasting spearmint green color for easyvisualization during surgery and in the event of anyrevision procedures.RALLY can be hand-mixed (HV and MV), vacuum-mixed (MV), ormixed and dispensed in a unique All-in-One system (HV and MV).The All-in-One system contains both the monomer and powderin one device, removes risk of contamination or broken glass,and is vacuum-compatible for decreased porosity.RALLY has lower porosity than competitive cements due to itspowder characteristics, even when hand-mixed.3,4 Bone cementporosity is caused by air bubble inclusions and is seen as thestarting point for fatigue fractures.5RALLY has shown excellent shear, tensile, and bending strengthscompared to competitive cements based on independentlypublished data.6,7,8 Shear, tensile, and bending stresses arebelieved to be the most common sources of cement failure.9,10Important termsPorosity: The presence of air pockets in the mixed cements; lower porosityresults in higher fatigue strength.5Shear strength: Strength of a material against sliding forces parallel to thedirection of forceTensile strength: Strength of a material against stretching or pulling forcesBending strength: Strength of a material against deforming or breakingunder a force, also known as flexural strengthConfidential – For internal use only by Smith & Nephew employees and sales force.

Cement mixing techniquesThe following technique is for informational and educational purposes only. It is not intended to serve as medical advice. It is the responsibility of thetreating physician to determine and utilize the appropriate products and techniques according to their own clinical judgment for each of their patients.For detailed product information, including indications for use, contraindications, effects, precautions and warnings, please consult the product'sInstructions for Use (IFU) prior to useHand mixing technique – Bowl and spatulaThe RALLY HV bone cement is recommended to be mixed by bowl and spatula as it is a high viscosity cementand more easily and uniformly mixed by hand. The RALLY MV cement can also be mixed by hand if desired.Break the ampoule of monomer at the neck and pour into the sterile mixing bowl.Note: Take care to gently break away from the body as to prevent injury and small glass particles in the mixture.2. Add all of the powder from the packet carefully into the bowl.3. Stir with the spatula slowly and carefully for one minute taking care to avoid spilling contents.4. Allow to stand for 30 seconds* for the escape of air and for cement to reach the dough phase.1.Vacuum mixing technique – RALLY All-in-One SystemThe RALLY All-in-One System is a premier, unique product composedof 70g of antibiotic cement completely contained inside the mixingand dispensing system. The cement components are isolatedfrom outside contamination or influences and has a filter screen toprevent glass from entering the final cement mixture. This systemcomes in both RALLY HVAB and RALLY MVAB formulations.The RALLY All-in-One system can be connected to a vacuum sourcesuch as a wall suction or dedicated vacuum pump, or it can beused without vacuum.2. With the system standing upright on the base, pop the monomervial with a sharp hit to the button on the top of the system. Whenyou see monomer flowing, pump the release button several timesto transfer all of the monomer into the powder chamber.1.Tip: Before releasing the monomer, invert the system and lightlytap the powder chamber to loosen the powder.3. Grab the base mixing handle and pull the mixing handle in andout for one minute.Tip: After a few seconds of mixing upright, turn the device upsidedown and tap the mixing chamber several times to loosen anypowder not yet mixed in.4. Disconnect the vacuum source.5. Fully extend the mixing handle until it is engaged and turn thehandle counter clockwise to disengage it from the system.6. Attach the breakaway nozzle by screwing onto the end of systemwhere the mixing handle was disconnected.7. Push the monomer end of the system into the powder chamberand load the whole system into the RALLY All-in-One CementGun for dispensing.Tip: Pushing the monomer chamber into the powder chamberto the point where cement reaches the dispensing point beforeloading into the gun, removes more air from the cement chamber.*Adjust according the temperature/time data for RALLY HV and RALLY MV cements.Confidential – For internal use only by Smith & Nephew employees and sales force.

Vacuum mixing technique – VORTEX Mixing SystemToday, most operating rooms mix cement under a partial vacuum, which helps to decreaseporosity and fumes created during mixing. The following is a brief description of the mixingtechnique using RALLY MV (40g 1 dose) and the VORTEX Vacuum Mixer.The VORTEX should be connected to a vacuum source such as a wall suction or dedicatedvacuum pump.2. Pour powder and monomer into the bowl as follows: 1 Dose – Pour all powder into the bowl, then all the liquid monomer down the side chute. 2 Doses – Pour 1 packet of powder into the bowl, followed by 1 ampoule of monomerdown the side chute. Repeat with second packet of powder and ampoule of monomer. 3 Doses* – Follow the procedure for 2 doses, repeating with the third dose of the cement.3. Affix the VORTEX lid with the stirring element firmly attached.4. Activate the vacuum source to 25mmHg.5. Turn the VORTEX handle at 2 cycles per second for 1 minute.1.Tip: Tap sharply on the side of the mixer occasionally during mixing to dislodge anyunwetted powder in the bowl.6. Shut off the vacuum and remove the vacuum from the mixer. Remove the lid.To apply cement via syringe application:Extract the funnel and cartridge (inner components) from the mixer and unscrewthe funnel.8. Connect the desired nozzle.9. Place the assembly in the VORTEX gun for dispensing.7.To apply cement via bowl and spatula:7. Extract the funnel and cartridge and insert the push up rod into the base of the cartridge.8. Push the rod upwards until all of the cement is inside the funnel.9. Use as a bowl.Note: The VORTEX mixer can be reused if another batch of cement is needed, unlikeother mixing systems. Simply remove the stirring element, funnel, and cartridge fromthe VORTEX mixer and install the new components from the VORTEX Re-Use Kit.*Not recommended for RALLY HV.Confidential – For internal use only by Smith & Nephew employees and sales force.

Total Hip Arthroplasty cementing procedureThe following cemented hip stem technique is a portion from the Smith & Nephew cemented hip stem surgicaltechniques for CPCS, Spectron, and Synergy stems. Please reference the Surgical Techniques for CPCS, Spectron,and Synergy stems as well as the Indications for Use for all products listed.11,12,13Step 1The proximal flange of the BUCK cement restrictorshould always be larger than the distal canaldiameter to ensure a good canal fit. Accuratecement restrictor depth placement is thendetermined by placing the prosthesis selectedfor implantation next to the inserter (Figure 1)and adding 2cm to the length.Figure 1Step 2 (Optional)Remove the vent-occluding membrane byinserting the vent-opening tool into the threadedend of the restrictor and pushing the pin throughthe venthole (Figure 2). Remove and discard theplastic membrane.Figure 2Step 3Screw the cement restrictor onto the inserter witha clockwise motion. Insert the device to the level ofthe medullary canal you have already determined(Figure 3). Once this level has been reached,disengage the restrictor from the inserter witha counterclockwise twisting maneuver. Removethe inserter from the medullary canal. Should itbe necessary to remove the restrictor prior tocement insertion, it can be re-attached to theinserter rod and pulled out of the canal. In thisway, the surgeon may adjust the restrictor asmany times as required. After placing the BUCKcement restrictor, prepare the femoral canal bypulse lavaging, clearing debris with the femoralcanal brush, and repeat lavaging if necessary toremove remaining debris.Figure 3Confidential – For internal use only by Smith & Nephew employees and sales force.

Step 4After insertion of the BUCK restrictor, the femoralcanal should be cleaned and dried. First usethe POWERPULSE lavage system to clean thecanal. Next, hook the femoral suction absorberto suction and place back inside the canal whilemixing the cement (Figure 4).Step 5Fill the canal with bone cement in a retrogrademanner (Figure 5). It is important that the proximalfemur be filled with cement that is placed underpressure to assure adequate packing of theproximal femur.Step 6After the cement is injected into the canal,break off the long nozzle and place the femoralpressurizer over the short nozzle. Apply thedisposable femoral pressurizer into the mouth ofthe canal (Figure 6). This will occlude the canaland compress the cement. Maintain firm pressureuntil the cement is in the doughy state and canwithstand displacement and will allow for propercement interdigitation into the trabecular bone.Withdraw the femoral pressurizer and removeany extruded cement around the periphery ofthe canal.Step 7Once the cement is securely packed in theconfines of the medullary canal, insert the femoralcomponent (Figure 7). Note that the restrictor levelmaintains a 2cm cement mantle at the distal endof the prosthesis.Figure 4Figure 5Figure 6Step 8After the stem has been inserted into the canal,remove any excess cement around the prosthesiswith the Concise Cement Sculps (Figure 8).Figure 7Figure 8Confidential – For internal use only by Smith & Nephew employees and sales force.
