Do not use steel wool or abrasive cleaners. Avoid solutions containing iodine or high chlorine content. Soiled or used Synthes devices should not be loaded in a case and cleaned in a mechanical washer. Synthes devices must be cleaned separately from Synthes instrument trays and Synthes cases. Soiled devices are devices that have blood, tissue and/or bodily fluid/matter in or on the surface of the devices. Long, narrow cannulations, blind holes and intricate parts require particular attention during cleaning. All devices must be thoroughly cleaned. Synthes instruments are critical devices and must be terminally sterilized prior to use. The sterilization parameters are only valid for devices that are adequately cleaned. Do not stack trays of instruments in a mechanical washer. Immediate-Use Steam Sterilization is only intended for individual instruments and should only be considered under emergency situations. The following parameters are only valid for properly installed, maintained, calibrated and compliant reprocessing equipment. Cleaning agents with a pH within 7 – 9 are recommended. The recommended cleaning method for Power tools is manual. Do not place Power tools in an ultrasonic cleaner. Do not submerge Power tools in aqueous solutions. Refer to product specific literature for care of Power tools. The sterilization parameters cannot be used for the Synthes Power Drive Unit, PN: 530.100, Power Drive Set, PN: 105.957, Synthes Piezoelectric Handpiece, PN: 05.001.401 and the Synthes Piezoelectric System, PN: 68.001.400. For the Synthes Power Drive Unit and Power Drive Unit Set, the Synthes Piezoelectric Handpiece and Piezoelectric System, please refer to the User Manuals for Sterilization guidelines. Surgical patients identified as at-risk for Creutzfeldt-Jakob disease (CJD) and related infections should be treated with single-use instruments. Dispose of instruments used or suspected of use on a patient with CJD after surgery and/or follow current national recommendations.
Repeated processing cycles that include ultrasonic, mechanical washing and sterilization have minimal effects on Synthes surgical instrumentation. End of life of a device is normally determined by wear and damage due to use. Evidence of damage and wear on a device may include but is not limited to corrosion (i.e. rust, pitting), discoloration, excessive scratches, flaking, wear and cracks. Improperly functioning devices, devices with unrecognizable markings, missing or removed (buffed off) part numbers, damaged and excessively worn devices should not be used.

Wipe blood and/or debris from device throughout surgical procedure to prevent it from drying onto the surface. Flush cannulated devices with sterile or purified water to prevent the drying of soil and/or debris to the inside. Soiled devices should be separated from non-contaminated devices to avoid contamination of personnel or surroundings. Devices should be covered with a towel dampened with sterile or purified water to prevent blood and/or debris from drying.
Point of Use Care
Soiled devices should be transported separate from non-contaminated devices to avoid contamination.

It is recommended that devices should be reprocessed as soon as is reasonably practical following use. Disassemble device, if device is able to be disassembled, prior to cleaning. Refer to technique guide or other supplemental information for specific device disassembly and/or reassembly instructions. Open devices with ratchets, box locks or hinges. Remove sharp devices for manual cleaning or place into a separate tray. Lumens/cannula of devices should be manually processed prior to cleaning. Lumens/cannula should first be cleared of debris. Lumens/cannula should be brushed thoroughly using appropriately sized soft-bristled brushes and twisting action. Brushes should be tight-fitting. Brush size should be approximately the same diameter of the lumen/cannulation to be cleaned. Using a brush that is too big or too small for the diameter of the lumen/cannulation may not effectively clean the surface of a lumen/cannulation. After brushing lumens/cannula, blow clean compressed air through lumen/cannulation to clear debris, if necessary. Soak and/or rinse heavily soiled devices or cannulated devices prior to cleaning to loosen any dried soil or debris. Use a neutral pH enzymatic soak or detergent to soak devices. Follow the enzymatic cleaner or detergent manufacturer’s instructions for use for correct exposure time, temperature, water quality and concentration. Use cold tap water to rinse devices. Synthes devices must be cleaned separately from Synthes instrument trays and Synthes cases. Lids should be removed from cases for the cleaning process, if applicable.

Rigid Sterilization Container Use Instructions and Considerations In order to ensure proper sterilization of Synthes’ devices when using a rigid sterilization container, the following must be taken into consideration: o Only FDA-cleared rigid sterilization containers may be used with Synthes’ devices and loaded graphic cases (a graphic case with all or part of its assigned contents). o The rigid sterilization container manufacturer’s instructions for use are to be followed. If questions arise regarding the use of the rigid sterilization container, Synthes recommends contacting the manufacturer of that specific container for guidance. o The options in using rigid sterilization containers with Synthes’ devices and loaded graphic cases are as follows: No more than one (1) fully loaded graphic case can be placed directly into a rigid sterilization container. Instrument trays from no more than one (1) loaded graphic case can be placed in the rigid sterilization container. Stand-alone modules/racks or single devices must be placed, without stacking, in a container basket to ensure optimal ventilation. o Rigid sterilization container must have a maximum volume to vent ratio of no greater than 127in3/in2. For any questions related to the volume to vent ratio, please contact the container manufacturer. o Only rigid sterilization containers approved for pre-vacuum steam sterilization can be used with Synthes’ devices and loaded graphic cases following the sterilization parameters provided by Synthes. o End-users should follow ANSI/AAMI ST79 for additional information concerning the use of rigid sterilization containers.

132°C (270°F)
20 minutes
*When applying dry times to Synthes cases and their accessories, dry times outside the standard healthcare prevacuum parameters may be required. This is especially important for polymer-based (plastic) cases/trays used in conjunction with heavy duty nonwoven sterilization wraps. The current recommended dry times for Synthes cases can range from a standard 20 minutes to an extended time of 60 minutes. The dry time is most often influenced by the presence of polymer based (plastic) materials; therefore, changes such as elimination of silicone mats and/or change in sterile barrier system (e.g. heavy grade to light grade wrap or the use of rigid sterilization containers) can reduce the necessary dry time. Dry times may be highly variable due to differences in packaging materials (e.g. nonwoven wraps), environmental conditions, steam quality, device materials, total mass, sterilizer performance and varying cool down time. The user should employ verifiable methods (e.g. visual inspections) to confirm adequate drying. • The autoclave manufacturer’s operating instructions and recommended guidelines for maximum sterilization load should be followed. The autoclave must be properly installed, maintained, and calibrated. Only legally marketed, FDA-cleared sterilization barriers (e.g. wraps, pouches or containers) should be used by the end-user for packaging terminally sterilized devices. • Most devices are designed to be sterilized assembled unless: o Etched with "Disassemble for Sterilization"; o The graphic case is not configured for the assembled device or o According to instructions in product specific information. •
Immediate-Use Steam Sterilization is only intended for individual instruments and should only be considered under emergency situations and when approved by local policies. Synthes does not support Immediate-Use Steam Sterilization of instrument sets, cases or implants. The following steam sterilization cycle is an example of a validated cycle for individual instruments only: o Unwrapped instrument o 132 °C (270 °F) for 4 (four) minutes Exceptions listed in the Cautions section of this document are not intended for Immediate-Use Steam Sterilization. Refer to the technique guide or other supplemental instruction to determine if device needs to be disassembled for sterilization. Immediate-Use Steam Sterilization should be performed in accordance with current AORN and AAMI recommendations.
