MERCURY SPINAL System Instructions for Use

5. Grossly distorted anatomy caused by congenital abnormalities. 6. Any other medical or surgical condition which would preclude the potential benefit of spinal implant surgery. 7. Rapid joint disease, bone absorption, osteopenia. Osteoporosis is a relative contraindication since this condition may limit the degree of obtainable correction, stabilization, and/or the amount of mechanical fixation. 8. Any case where the implant components selected for use would be too large or too small to achieve a successful result. 9. Any patient having inadequate tissue coverage over the operative site or inadequate bone stock or quality. 10. Any patient in which implant utilization would interfere with anatomical structures or expected physiological performance. 11. Any case not needing bone graft and fusion. 12. Any case not described in the indications for use. 13. Reuse or multiple use. 14. Any contraindications to the compatible Medtronic StealthStation System are applicable to the Mercury® System. WARNINGS Implants and instruments are provided non-sterile. Instruments must be cleaned and sterilized before use. Implants may be reprocessed prior to use and must be sterilized before use. Validated sterilization cycle parameter protocols are noted in the STERILIZATION section of this insert. Implants that have come in direct contact with a patient or bio-contaminants should be disposed of. Some instruments may be sharp, depending on their intended use. Care should be taken in handling such instruments to avoid injury to the user or patient. The safety and effectiveness of pedicle screw systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grade 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocations, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudoarthrosis). The safety and effectiveness of these devices for any other conditions are unknown. A successful result is not always achieved in every surgical case. This fact is especially true in spinal surgery where many extenuating circumstances may compromise the results. System components are temporary implants used for the correction and stabilization of the spine. Devices are intended to be used to augment the development of a spinal fusion by providing temporary stabilization. Devices are not intended to be the sole means of spinal support. Use of these products without a bone graft or in cases that develop into a non-union will not be successful. No spinal implant can withstand body loads without the support of bone. In this event, bending, loosening, disassembly and/or breakage of the device(s) will occur. Precaution: Implantation of pedicle screw spinal systems should be performed only by experienced surgeons with training in the use of spinal devices. This is a technically demanding procedure presenting a risk of serious injury to the patient. Preoperative and operating procedures including knowledge of surgical techniques, proper reduction, and proper selection and placement of the implant are important considerations in the successful utilization of this device by the surgeon. Further, the proper selection and compliance of the patient will greatly affect the results. The physician should consider the levels of implantation, patient weight, patient activity level, and all other patient conditions that may have an impact on the performance of this device. Patients who smoke have been shown to have an increased incidence of non-union. These patients should be advised of this fact and warned of this consequence. Obese, malnourished, and/or alcohol abuse patients are also poor candidates for spine fusion. Patients with poor muscle and bone quality and/or nerve paralysis are also poor candidates for spine fusion. Note: Components of this system should not be used in conjunction with other systems unless specifically specified in this package insert. Physician Note: The physician is the learned intermediary between the company and the patient. The indications, contraindications, warnings, and precautions given in this document must be conveyed to the patient. 1. Spinal Elements Navigated Instruments are validated for use with the StealthStation S7 system and software version v2.1.0. Do not attempt to use Spinal Elements Navigated Instruments with other models and software versions. 2. Spinal Elements is not a navigation software and system provider. Instructions for use and handling of third-party navigation systems are the responsibility of the hospital and navigation company. Refer to the navigation company’s software and user guides for navigation guidance. The navigation system should be set up per the manufacturer's instructions. 3. Examine all instruments for damage and deterioration prior to use. Do not use any instruments that are damaged. 4. All instruments must be successfully verified and registered prior to use. Do not use instruments that have not been successfully verified and registered with navigation. 5. Navigation accuracy should be frequently assessed during the procedure.

Verify that the StealthStation model and software version is correct. Spinal Elements Navigated Instruments are validated for use with the StealthStation S7 and software version v2.1.0. 2. The surgeon should consider for surgery only those patients indicated for the use of this device. 3. The surgeon should not consider for surgery those patients contraindicated for the use of this device. 4. The surgeon should have a complete understanding of the device’s indications, contraindications, and applications. 5. The surgeon should have a complete understanding of the function and limitations of each implant and instrument. 6. Device components should be received and accepted only in packages that have not been damaged or tampered with. Components must be carefully handled and stored in a manner that prevents scratches, damage, and corrosion. 7. All implants and instrument should be inspected for wear and tear prior to use. Devices presenting damage such as cracks, corrosion, bends etc. should not be used. Compromised devices should be segregated and be returned to Spinal Elements. 8. The type of implant to be used for the case should be determined prior to beginning the surgery. 9. All instruments and implants should be processed and sterilized prior to use. INTRAOPERATIVE MANAGEMENT 1. Caution should be taken in handling the implants. Damage to the implants may affect their performance. INS-MER

Rev. 20210119

2. Extreme caution should be used around the spinal cord and nerve roots. Damage to the nerves will cause loss of neurological functions. 3. Breakage, slippage, or misuse of instruments or implant components may cause injury to the patient or operative personnel. 4. Care should be taken during intraoperative forming of the rods. Sharp bends or notches in the rods may decrease their functional strength. Rods should not be repeatedly or excessively bent. Rods should never be reverse bent in the same location. If the rods are cut to length, they should be cut in such a way as to create a flat, non-sharp surface perpendicular to the midline of the rod. If the rods are cut, cut them outside of the operative field. Whenever possible, it is recommended to use precut rods. 5. Whenever possible or necessary, an imaging system should be utilized to facilitate surgery. 6. When the polyaxial head is at the limit of its angulation, care should be taken to ensure the head can properly accommodate the rod. The head should be perpendicular to the rod upon final-tightening. 7. Care should be taken when tapping or inserting screws. Proper size selection is critical. Incorrectly sized taps or screws may cause nerve damage, hemorrhage, or other possible adverse events listed in this package insert. 8. Always use supplied gauges to verify the sizes of screws to be implanted prior to implantation. Do not rely solely on markings or color coding on the implants. 9. Caution should be taken not to over-tighten implants, instruments, and interfaces between implants and instruments. 10. Before closing the soft tissue, all screws or locking/securing mechanisms should be tightened. Recheck the tightness of all components after finishing to ensure that none loosened during the tightening of other components. 11. Implants should not be reused under any circumstances. POSTOPERATIVE MANAGEMENT Postoperative management by the surgeon, including instruction and warning to and compliance by the patient, of the following is essential: 1. The patient should have a complete understanding of and compliance with the purpose and limitations of implant devices. 2. Postoperative patients should be instructed to limit activity as determined by their surgeon. If partial weight bearing is recommended or required prior to firm bony union, the patient must be warned that bending, loosening, and/or breakage of the device(s) are complications which may occur as a result of excessive or early weight bearing or muscular activity. The risk of bending, loosening, or breakage of a temporary internal fixation device during postoperative rehabilitation may be increased if the patient is active, or if the patient is debilitated or demented. The patient should be warned to avoid falls or sudden jolts in the spinal position. 3. To allow the maximum chances for a successful surgical result, the patient or devices should not be exposed to mechanical vibrations or shock that may loosen the device construct. The patient should be warned of this possibility and instructed to limit and restrict physical activities, especially lifting and twisting motions and any type of sport participation. The patient should be advised not to smoke tobacco or utilize nicotine products, or to consume alcohol or non-steroidal or antiinflammatory medications such as aspirin during the bone graft healing process. 4. The patient should be advised of their inability to bend or rotate at the point of spinal fusion and taught to compensate for this permanent physical restriction in body motion. 5. Failure to immobilize a delayed or non-union of bone will result in excessive and repeated stresses on the implant. By the mechanism of fatigue, these stresses can cause the eventual bending, loosening, or breakage of the device(s). It is important that immobilization of the spinal surgical site be maintained until firm bony union is established and confirmed by roentgenographic examination. If a state of non-union persists or if the components loosen, bend, and/or break, the device(s) should be revised and/or removed immediately before serious injury occurs. The patient must be adequately warned of these hazards and closely supervised to ensure cooperation until bony union is confirmed. 6. The implants are temporary internal fixation devices. Internal fixation devices are designed to stabilize the operative site during the normal healing process. After the spine is fused, these devices serve no functional purpose and may be removed. While the final decision on implant removal is up to the surgeon and patient, in most patients, removal is indicated because the implants are not intended to transfer or support forces developed during normal activities. If the device is not removed following completion of its intended use, one or more of the following complications may occur: (1) corrosion, with localized tissue reaction or pain; (2) migration of implant position, possibly resulting in injury; (3) risk of additional injury from postoperative trauma; (4) bending, loosening and breakage, which could make removal impractical or difficult; (5) pain, discomfort, or abnormal sensations due to the presence of the device; (6) possible increased risk of infection; (7) bone loss due to stress shielding; and (8) potential unknown and/or unexpected long term effects such as carcinogenesis. Implant removal should be followed by adequate postoperative management to avoid fracture, re-fracture, or other complications. 7. Retrieved implants should be properly disposed of and are not to be reused under any circumstance. SINGLE USE Reuse of a single use device that has come in contact with blood, bone, tissue or other body fluids may lead to patient or user injury. Possible risks associated with reuse of a single use device include, but are not limited to, mechanical failure, serious injury, transmission of infectious agents and death. INS-MER

Implants that have directly come in contact with the patient or bio-contaminants should be discarded. Separate inserts for implants from the instrument tray prior to and during any processing. CLEANING AND MAINTENANCE All devices must be free of packaging material prior to sterilization. All instruments must be free of bio-contaminants prior to sterilization. Cleaning, maintenance and mechanical inspection must be performed by hospital personnel trained in the general procedures involving contaminant removal. Only neutral pH cleaners or detergents labeled for use in cleaning medical devices should be used for cleaning components. Only lubricants that are intended for use on surgical instruments should be used to lubricate instruments. Follow directions from the manufacturer of lubricating and cleaning agents regarding handling, concentration, and use of such agents. Cleaning instructions are provided in accordance with recognized standards and regulations and are intended to supplement a hospital’s existing device cleaning and disinfecting protocol. Contaminated devices should be wiped clean of visible soil at the point of use prior to transfer to a central processing unit for cleaning and sterilization. Contaminated devices must be cleaned promptly after use per the instructions provided in this insert to minimize drying and ensure an effective cleaning. AUTOMATED CLEANING INSTRUCTIONS All devices must be processed manually prior to automated cleaning. Follow the instructions below for the manual and automated washing. PRE-AUTOMATED WASHER: MANUAL CLEANING 1. Disassemble all instruments that come apart for cleaning. 2. Rinse under running tap water to remove gross contamination. Use a syringe, wire guide and/or pipe cleaner (as appropriate to the presented cleaning challenge) to push debris out of lumens/cannulations or other hard to reach areas. Pay special attention to lumens of the external shafts of disassembled instruments. 3. Prepare Enzol® (or equivalent neutral or mild pH enzymatic cleaner) according to manufacturer recommendations using warm tap water. Fully immerse devices in the enzymatic cleaner solution and allow to soak for a minimum of 1 minute. While soaking, actuate the instruments through a full range of motion (as appropriate) to allow complete penetration of the cleaning solution. Instruments that do not disassemble may require additional soaking. 4. After the soak, remove the instruments and wipe any soil or debris using a disposable towel. Then, place the instruments into a fresh batch of enzymatic cleaning solution using warm water. Scrub the entire surface of the devices with a soft bristle brush paying particular attention to hard to reach areas such as mated surfaces. A syringe, wire guide, and/or pipe cleaner should be used to aid in cleaning lumens/cannulations or other hard to reach areas. A minimum of 60ml of detergent should be used when flushing lumens and cannulations. Ensure no soil is visible in the rinse stream. 5. Remove from enzymatic cleaner solution and rinse with reverse osmosis or de-ionized (RO/DI) water for a minimum of 30 seconds to remove any residual cleaner solution. Thoroughly and aggressively flush lumens, holes and other hard to reach areas with a minimum of 60ml of water. 6.
