Bone cement consists of a powder and a liquid. The mixing of these two components initially produces a paste, which is used to anchor the prosthesis to the bone. The hardened bone cement allows stable fixation of the prosthesis and transfers stresses associated with movement to the bone via the large interface. Insoluble zirconium dioxide is included in the cement powder as an X-ray contrast medium. The chlorophyll additive serves as optical marking of the bone cement at the site of the operation. The GMS content is designed to protect against infections caused by bacterial invasion of the prosthesis and the surrounding tissue by gentamicin-sensitive strains. The purpose of the current 510(k) notification is to introduce a new source of GMS to secure the supply chain and ensure a double-sourcing for the manufacturing of Refobacin Bone Cement R. Indeed, the GMS antibiotic particles used in the Refobacin Bone Cement R are larger than the particles of the raw material delivered by the by the vendor who performs the synthesis of gentamicin. As the use of larger particles enhances the gentamicin release from the bone cement, an additional processing step of precipitation is necessary. Furthermore, the labeling of the subject device will be updated. These labeling changes are not related to the new vendor of GMS. | | | {5} Please note that this $10(k)$ notification will cover only one RBCR item (110034355) following the discontinuation of the other RBCR items since the last clearance (110034356, 110034357 and 110034358). ## Intended Use/Indications for Use **21 CFR 807.92(a)(5)** Refobacin Bone Cement R is indicated to be used for stable anchoring of suitable joint prostheses to the bone, in hip and knee revision arthroplasty operations when reconstruction is necessary because of revision of previous arthroplasty procedures due to joint infection, also in case an infection with gentamicin-sensitive strains is a potential risk. Refobacin Bone Cement R is indicated to be used in the second stage of a two-stage revision for total joint arthroplasty after the initial infection has been cleared. ## Indications for Use Comparison **21 CFR 807.92(a)(5)** The subject device has similar Indications for Use as the predicate Refobacin® Bone Cement R device. The indications have been limited to hips and knees arthroplasty procedures which are within the currently cleared indications. Indeed, the device was cleared for use in hips, knees and other joints arthroplasty, while the subject device is intended to be marketed for only two of those indications. ## Technological Comparison **21 CFR 807.92(a)(6)** The rationale for substantial equivalence is based on consideration of the following characteristics: - Indications for use: Similar to predicate device - Other clinical characteristics: Similar to predicate device - Labeling: Different from predicate device - Technical/design characteristics: Similar to predicate device - Biological characteristics/materials: Similar to predicate device - Manufacturing process: Similar to predicate device - Sterilization: Identical to predicate device - Packaging: Similar to predicate device ## Non-Clinical and/or Clinical Tests Summary & Conclusions **21 CFR 807.92(b)** Non-clinical testing on Refobacin Bone Cement R has been performed during the design and development of the subject device based on the user needs and risk analysis and the impacts that this new source of gentamicin sulfate may have on the final product specifications. A demonstration that the subject device meets the same product specifications as the predicate device has been conducted. The complete list of non-clinical testing that has been performed (including the new studies performed for the proposed change) is provided below: - Incipient Break & Assembly - Creep properties - Fatigue properties / Fatigue performance - Fracture Toughness - Porosity - Radiopacity - Shear strength - Tensile Properties - Volume variation of bone cement upon Polymerization - Use of antibiotics in bone cement - Literature Review of compatibility between bone cement and surgical devices - Literature review on the effect of cement multilayer on the mantle's mechanical properties - Shelf-life verification of bone cement R - Study of temperature excursion on Cement Pack - Shelf-life verification of bone cement R – Copo E - Design verification of Monomer/Cement powder ratio by handling and setting assessment - Performance testing between bone cement and disposable mixing Bowl with Spatula - Mechanical and behavioral properties as a function of mixing options - RBCR containing Gentamicin Sulfate from Corden Pharma at industrial scale - Dough extrusion - Design Verification of RBCR blended with Osartis Gentamicin Sulfate raw material - Fatigue performance - RBCR powder containing Gentamicin from Merck Vs Osartis - Molecular weight {6} - Zone of inhibition of RBCR with Osartis gentamicin sulfate - Antibiotic release - Bibliographic evaluation of Swelling - MR Safety - Summative Evaluation - EU MDR Labeling - Summative Evaluation - RBCR The results obtained from the various studies demonstrate that both the subject device and the predicate device comply with all requirements, which confirms that this change does not impact the claimed product performances, ensuring product quality and patient safety. Not applicable The reports provided demonstrate the proposed subcontractor for gentamicin sulfate particle size enlargement for Refobacin Bone Cement R devices meets FDA requirements and the finished device will perform as intended. Therefore, Biomet France concludes that the device is substantially equivalent to the predicate device. --- **Source:** [https://fda.innolitics.com/device/K254107](https://fda.innolitics.com/device/K254107) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
