Device Description Advanced Bone Plate is mainly used for internal fixation of hand, wrist, foot, ankle and distal fibular fractures. According to the anatomical characteristics of human bones, locking plates of different shapes and locking screws of different diameters are designed. In clinical practice, locking bone plate and locking bone screw are used in combination to play the role of temporary internal stent, providing a stable local environment for fracture ends and creating conditions for the healing of fracture ends. Bone plates in Advanced Bone Plate are made of titanium alloy following ASTM F1472, and bone screws in Advanced Bone Plate are made of titanium alloy following ASTM F136. Advanced Bone Plate is provided as non-sterile. The implants are intended for single-use only, while the instruments are reusable. # 5. Indications for Use The Advanced Bone Plate (AIMINI VARIABLE ANGLE LOCKING PLATES SYSTEM, ITVAL Foot & Ankle VAL System, and Distal Fibular VAL Plate) is indicated for internal fixation. Specific indications for the plates included in the system as follows: {5}------------------------------------------------ The AIMIMINI VARIABLE ANGLE LOCKING PLATES SYSTEM is indicated for the internal fixation (fractures, osteotomies, arthrodesis, replantations and reconstructions) of the hand (metacarpals and phalanges) and wrist of adults and adolescents (age 12-21 years) in which growth plates have fused or will not be crossed by fixation. The ITVAL Foot & Ankle VAL System is indicated for internal fixation (fractures, osteotomies, fusions, nonunions, malunions, small fragment replantations) of the foot and ankle in adults and adolescents (age 12-21 years) possessing normal or osteopenic bone where growth plates have fused or will not be crossed by fixation. The Distal Fibular VAL Plate is indicated for internal fixation (fractures, osteotomies, nonunions, malunions, small fragment replantations) of the distal fibula of adults and adolescents (age 12-21 years) where growth plates have fused or will not be crossed by fixation. #### 6. Comparison of Technological Characteristics with the Predicate Device The rationale for substantial equivalence is based on consideration of the following characteristics: Regulatory Classification: Same as the predicate devices Indications for Use: Substantially equivalent (SE) to the predicate devices Materials: Bone plates in Advanced Bone Plate are made of titanium alloy following ASTM F1472, and bone screws in Advanced Bone Plate are made of titanium alloy following ASTM F136. Both of the materials of bone plates and bone screws are substantially equivalent (SE) to the predicate devices. Design Features: The subject Advanced Bone Plate shares the same fundamental technological characteristics as the predicate systems. The same design features of the subject and predicate systems such as variable angle locking technology, limited contact profiles, anatomic contours, and similar size ranges. Based on the presented comparisons and discussions, the subject Advanced Bone Plate does not raise any new issues of safety and efficacy. #### 7. Non-Clinical Performance Data ## 7.1 Biocompatibility testing The biocompatibility evaluation for the Advanced Bone Plate was conducted in accordance {6}------------------------------------------------ with the FDA Guidance "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". #### 7.2 Mechanical testing The mechanical tests of bone plates were performed per ASTM F382-17 Standard Specification and Test Methods for Metallic bone plate and Three-point Bending Test Method to demonstrate substantially equivalent of safety and efficacy with the predicate device. According to ASTM F382-17 and Three-point Bending Test Method, test methods are used to determine the Bending Stiffness, Bending Strength and Bending Structural Stiffness. The mechanical tests of bone screws were performed per ASTM F543-17 Standard Specification and Test Methods for Metallic Medical Bone Screws to demonstrate substantially equivalent of safety and efficacy with the predicate device. According to ASTM F543-17, test methods are used to determine the Torsion Test, Insertion/removal Test and Pullout Test. # 7.3 Sterilization & Reprocessing The Advanced Bone Plate is provided as non-sterile. It required to be sterilized via Overkill Approach (Half-Cycle method) to reach a SAL of 10-6 by the hospital prior to surgery. The sterilization method is presented in the instruction for use, which was validated per ISO 17665-1: 2006 Sterilization of health care products - Moist heat - Part 1: Requirements for the development, validation, and routine control of a sterilization process for medical devices. Implants and instruments must be carefully cleaned before initial sterilization. The cleaning instructions presented in the instruction for use have been validated per FDA guidance AAMI TIR30:2003 "A compendium of processes, materials, test methods, and acceptance criteria for cleaning reusable medical devices. ### 8. Clinical Data No clinical performance data was provided to demonstrate substantially equivalence. #### 9. Conclusion Advanced Bone Plate is compared to the predicate devices in respect of safety and effectiveness. The information provided within this premarket notification demonstrates that proposed device is determined to be substantially equivalent (SE) to the predicate device.
