CERES®-C STAND-ALONE CERVICAL SYSTEM IMPLANTS AND INSTRUMENTATION This package insert covers the Ceres-C Stand-Alone Cervical System and Manual Surgical Instruments that are used for the implantation of this system. GENERAL INFORMATION The Ceres-C Stand-Alone Cervical System includes a PEEK spacer conforming to ASTM F2026 with tantalum x-ray markers conforming to ASTM F560, and a titanium alloy (Ti-6Al-4V ELI) interbody plate and screws conforming to ASTM F136. The spacer component is assembled to the interbody plate and implanted anteriorly. The endplate contacting surfaces of the spacer component include serrations, and the plate component includes two holes for inserting one bone screw in each vertebral body. The plate component also includes a screw lock at each hole. The bone screws are available in a variety of diameters and lengths. The interbody plate components are available in a variety of heights. The spacer components are available in a variety of depths, widths, and heights. INDICATION The Ceres-C Stand-Alone Cervical System is a stand- alone anterior cervical interbody fusion device indicated for use in skeletally mature patients with degenerative disc disease (DDD) with accompanying radicular symptoms at one level from C2-T1. DDD is defined as discogenic pain with degeneration of the disc confirmed by history and radiographic studies. These patients should have had six weeks of non- operative treatment. The Ceres-C StandAlone Cervical implant should be packed with autograft or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft and implanted with an anterior approach. CONTRAINDICATIONS 1. The Ceres-C Stand-Alone Cervical System is contraindicated in the presence of infection, pregnancy, metabolic disorders of calcified tissues, drug/alcohol abuse, mental illness, general neurologic conditions, immunosuppressive disorders, patients with known sensitivity to materials in the device, obesity and patients who are unwilling to restrict activities or follow medical advice. 2. Biological factors such as smoking, use of nonsteroidal anti-inflammatory agents, the use of anticoagulants, etc. all have a negative effect on bony union. Contraindications may be relative or absolute and must be carefully weighed against the patient’s entire evaluation. 3. This device is not intended for use except as indicated. 4. Prior fusion at the level(s) to be treated. 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 biocontaminants 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. 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. Implantation of devices 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. Patients with previous spinal surgery at the level(s) to be treated may have different clinical outcomes compared to those without a previous surgery. 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. MAGNETIC RESONANCE ENVIRONMENT The Ceres-C Stand Alone device has not been evaluated for safety and compatibility in the MR environment.

INTRAOPERATIVE MANAGEMENT 1. Caution should be taken in handling the implants. Damage to the implants may affect their performance. 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. Implants should be attached to the corresponding inserter such that they are fully seated on the inserter. Care should be taken not to over-tighten the implant to the inserter. 5. Implants should not be axially rotated with the inserter once they have been implanted. This may lead to damage of the implant and/or the inserter. 6. Whenever possible or necessary, an imaging system should be utilized to facilitate surgery. 7. Caution should be taken not to over-tighten threaded components, including instruments, implants, and interfaces between implants and instruments. 8. To assure proper fusion below and around the location of the fusion, autogenous bone graft should be used. 9. Implants should not be reused (used in additional patients) 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 the implant devices. 2. Postoperative patients should be instructed to limit activity as determined by their surgeon. 3. Retrieved implants should be properly disposed of and are not to be reused under any circumstances. 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. CLEANING AND MAINTENANCE GENERAL INFORMATION Spinal Elements’ instruments are manufactured from various stainless steels, aluminums, and polymers. All materials used have a history of use in such instruments. CLEANING AND MAINTENANCE Devices must be free of packaging material 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.
