IMPORTANT NOTE These implants are intended only to assist healing and are not intended to replace normal body structures. Delayed union or nonunion of bone in the presence of weight bearing or load bearing, could eventually break the implant due to metal fatigue. Therefore, it is important that immobilization of the operative site be maintained until firm bony union (confirmed by clinical and radiographic examination) is established. Factors such as the patient’s weight, activity level, and adherence to weight bearing or load bearing instructions have an effect on the load and number of cycles to which the implant is subjected. The surgeon must be thoroughly knowledgeable in the medical, surgical, mechanical and metallurgical aspects of the implants. Postoperative care is extremely important. The patient should be warned that noncompliance with postoperative instructions could lead to breakage of the implants and/or possible migration requiring revision surgery to remove the device.

ATTENTION OPERATING SURGEON DESCRIPTION The MaxAn Anterior Cervical Plate System is a plate and screw system composed of titanium alloy (Ti-6Al-4V ELI). The system includes self-drilling bone screws, which are available in various diameters. The plates have an integral locking component that secures the bone screws into the plate. Various instruments are available to facilitate implantation of the device. MATERIALS The MaxAn Anterior Cervical Plate System’s implants are made from Ti-6Al-4V conforming to ASTM standard F-136.
2. Selection of Implants. Selection of proper size, shape and design of the implant increase the potential for success. While proper selection can help minimize risks, the size and shape of human bones present limitations on the size and strength of implants. 3. Implant Strength and Loading. These devices are not designed to withstand the unsupported stress of full weight bearing and/or load bearing, and cannot withstand activity levels and/or loads equal to those placed on normal healthy bones. If healing is delayed or does not occur, the implant could eventually break due to metal fatigue. Loads produced by weight bearing and activity levels will dictate the longevity of the implant. 4. Corrosion. Contact of dissimilar metals (e.g., titanium and stainless steel) accelerates the corrosion process, which could enhance fatigue fracture of the implants. Therefore, only use like or compatible metals with implants that are in contact with each other.

PRECAUTIONS 1. Do Not Reuse. Do not reuse implants/devices. While an implant/device may appear undamaged, previous stress may have created imperfections that would reduce the service life of the implant/device. Do not treat patients with implants/ devices that have been even momentarily placed in a different patient 2. Handling of Implants. Titanium implants are to be handled with care. If contouring of the plate is required, avoid sharp bends and reverse or repetitive bends. Avoid notching or scratching of the device, which could produce internal stresses and lead to early breakage. Avoid bending across the screw holes. 3. Implant Removal After Healing. After healing is complete, the implant may be removed since it is no longer necessary. Implants that are not removed may result in complications such as implant loosening, fracture, corrosion, migration, pain or stress shielding of bone, particularly in young, active patients. Implant removal should be followed by adequate postoperative management. 4. Adequate Patient Instructions. A patient must be instructed on the limitations of the metallic implant, and should be cautioned regarding physical activity and weight bearing or load bearing prior to complete healing. 5. Surgical Techniques. The device is recommended for use by surgeons thoroughly familiar with the relative current literature, surgical techniques, implantation technique for this device, and postoperative care of the patient. Please refer to the specific surgical technique for this device for more information. 6. The surgeon must ensure that all necessary implants and instruments are on hand prior to surgery. The device must be handled and stored carefully, protected from damage, including from corrosive environments. They should be carefully unpacked and inspected for damage prior to use. 7. All instruments must be cleaned and sterilized prior to surgery. 8. Zimmer Biomet Spine implants should not be used with implants or instruments from another manufacturer for reasons of metallurgy, mechanics and design. 9. Based on fatigue testing results, when using the MaxAn Anterior Cervical Plate System, the surgeon should consider the levels of implantation, patient weight, patient activity level, other patient conditions, etc. which may impact the performance of this system. MRI SAFETY INFORMATION MR Conditional Non-clinical testing demonstrated that the MaxAn Anterior Cervical Plate is MR Conditional. A patient with this device can be scanned safely in an MR system immediately after placement under the following conditions: • Static magnetic field of 1.5-Tesla and 3-Tesla only • Maximum spatial gradient magnetic field of 3000 Gauss/cm (30 T/m) or less • Maximum MR system reported, whole body averaged specific absorption rate (SAR) of 2-W/kg for 15 minutes of scanning in the Normal Operating Mode of operation for the MR system • Under the scan conditions defined, the implants are expected to produce a maximum temperature rise of 2.7˚C after 15-minutes of continuous scanning. • When other methods of supplemental fixation are used, also follow the MR conditional labeling for the additional components.
Artifact Information MR image quality may be compromised if the area of interest is the same or relatively close to the position of the device, and it may be necessary to optimize the MR imaging parameters. In non-clinical testing, the shape of the expected artifact follows the approximate contour of MaxAn Anterior Cervical Plate and extends radially up to 26 mm from the implant when imaged using a gradient echo pulse sequence and a 3-Tesla MR system. POTENTIAL ADVERSE EFFECTS 1. Nonunion pseudarthrosis or delayed union 2. Bending, fracture, loosening or migration of the implant 3. Metal sensitivity or foreign body reaction 4. Decrease in bone density due to stress shielding 5. Pain, discomfort, or abnormal sensations due to presence of the implant 6. Nerve, soft tissue, or blood vessel damage due to surgical trauma 7. Fracture of bony structures 8. Spinal cord impingement 9. Dural Leak 10. Bursitis 11. Necrosis of the bone 12. Dysphagia/hoarseness 13. Hemorrhage 14. Infection 15. Death CLEANING INSTRUCTIONS 1. All Instrument components should be disassembled and rinsed with tap water. 2. Prepare solution of enzymatic surgical detergent and tap water by adding 2 oz. Of Enzol (Enzymatic Detergent, Johnson & Johnson) to 1 gallon of warm tap water (72ºF/22ºC to 109ºF/43ºC). Instrument components should be immersed in solution for 5 minutes. 3. Scrub components with soft brushes and rinse with a brisk stream of tap water (72ºF/22ºC to 109ºF/43ºC) until the instruments are visually clean. 4. Using an ultrasonic cleaner, sonicate all components in the same enzymatic solution (see step # 2) for 10 minutes. 5. Manually clean all components with soft brushes and repeat step # 3 until visually clean. This step should be repeated until the instruments are visually clean. 6. Dry components with a soft gauze cloth. 7. Inspect cleaned instrument for loose screws and pins, clamp alignment, cracks and other irregularities. 8. Lubricate instruments to protect instruments during sterilization and storage. This should be done with a water soluble, preserved lubricant after each cleaning. The lubricant should contain a chemical preservative to prevent bacterial growth and be made with distilled water. Excess lubricant should be wiped off prior to storage and sterilization. CARE AND HANDLING • All torque wrenches should be re- calibrated every 6 months. • Please refer to ASTM standard F1744-96, “Standard Guide for Care and Handling of Stainless Steel Surgical Instruments” for additional information. • Prior to use, instruments should be visually inspected and function should be tested to assure instruments are functioning properly. If instruments are discolored, have loose screws/pins, are out of alignment, are cracked or have other irregularities, Do Not Use. 060549-01-en Rev 08 2021-08
