The predicate devices are temporary spacers that have been classified under 21 CFR § 888.3360 and 888.3560, and are Class II medical devices. #### 4 DESCRIPTION OF THE DEVICE The Modular Spacers are sterile, single-use devices intended for temporary use (maximum 180 days) as ioint replacements. The Hip Modular Spacer is composed of two components (a head and a stem) that are intended to be used together to form a temporary hip spacer; the components are available in a range of sizes. The Knee Modular Spacer is composed of three independent components (a femoral component, a tibial component and a tibial insert component) that are intended to be used together to form a temporary knee spacer; the components are available in a range of sizes. The devices are made of fully formed polymethylmethacrylate (PMMA), which is radioopaque, and contains gentamicin and color additives to give a green color. The Modular Spacers provide a functional-mechanical mode of action; they provide patients a temporary implant allowing for a natural range of motion and partial weight-bearing during treatment. They are designed to preserve soft tissue to prevent further complications, such as muscular contraction, and to facilitate the subsequent joint replacement procedure. ### INDICATIONS FOR USE AND INTENDED USE ട് The Modular Spacers have the following indications for use statements. ### Hip Modular Spacer The Hip Modular Spacer, which consists of a modular head and stem, is indicated for temporary use (maximum 180 days) as an adjunct to total hip replacement (THR) in skeletally mature patients undergoing a two-stage procedure due to a septic process and where gentamicin is the most uppropriate antibiotic based on the susceptibility pattern of the infecting micro-organisms. The head and stem components are inserted into the acetubular cavity and femoral medullary canal, respectively, following removal of the existing acetabular and femoral components and radical debridement. {2}------------------------------------------------ The device is intended for use in conjunction with systemic antibiotic therapy (standard treatment approach to an infection). The Hip Modular Spacer is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implunted or another appropriate treatment performed (e.g. resection arthroplasty, fusion etc.). ### Knee Modular Spacer The Knee Modular Spacer, which consists of a modular femoral, tibial insert component, is indicated for temporary use (maximum 180 days) as an adjunct to total knee replacement (TKR) in patients undergoing a two-stage procedure due to a septic process and where gentamicin is the most appropriate antibiotic based on the susceptibility pattern of the infecting micro-organism(s). The device is applied on the femoral component) and on the tibial plate (tibial component) following removal of the existing implant and radical debridement. The use of the tibial insert component is optional. when a large tibial defect is present. The device is intended for use in conjunction with systemic antimicrobial untibiotic therapy (standard treatment approach 10 an infection). The Knee Modular Spacer is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion etc.). Because, of the inherent mechanical limitations of the device materials (gentamicin(polymethylmethacrylate), the device is only indicated for patients who will consistently use traditional mobility assist devices (e.g., crutches, walkers, canes) throughout the implantation period. This is the same intended use as the predicate devices. The Garventis Modular Spacers and the Tecres Interspace Hip and Knee devices are intended to be used in the same surgical procedure (two-stage revision procedure) in the same target patient population, and provide the same primary function of providing patients a temporary implant to allow for a natural range of motion and partial weight bearing. ### TECHNOLOGICAL CHARACTERISTICS AND PERFORMANCE DATA 6 The Garventis Modular Spacer devices share many similar technological characteristics compared to the predicate Tecres Interspace Hip and Knee devices. The Garventis Modular Spacers and the predicate Tecres Interspace Hip and Knee share a similar size, shape and geometry, and are made from the same materials (PMMA). Each hip device also contains an inner stainless steel core for support. The Garventis Modular Spacers and the predicate Tecres Interspace Hip and Knee both incorporate gentamicin. Both devices share the same tissue contact and duration of contact. Both are provided preformed to the user, sterile, for single-use. The design of the Hip Modular Spacer differs from the predicate device by its modular nature; it is provided as separate head and stem components, which have to be combined to achieve the final configuration of the implant. The design of the Knee Modular Spacer differs from the predicate device by its modular nature; it is provided as separate femoral and tibial components that must be coupled to achieve the final configuration of the implant. A tibial Insert is also available to be combined optionally with the Tibial component for increasing the final thickness. {3}------------------------------------------------ The performance data presented in this 510(k) application demonstrate the substantial equivalence of the Garventis Modular Spacers to the predicate devices, and to establish that the devices are as safe and effective as the predicates. Biocompatibility studies were conducted according to ISO 10993 to demonstrate that the device materials are safe, suitable and appropriate for their intended use. Physical, mechanical and pharmacological testing met the acceptance criteria to demonstrate the safety and effectiveness of the Garventis Modular Spacers. Static testing (ISO 5833) and fatigue testing (ASTM F2118) were conducted of the resin; fatigue testing (ISO 7206-4, ISO 7206-6, ASTM F1800, ISO 14243-1); surface roughness testing (1SO 4287-97) of the spacer device; head size comparison and disassembly test (ISO 7206-9) of the femoral head; antibiotic elution testing and bacterial anti-adhesivity testing. Data were presented to show the sterility of the device, the suitability and integrity of the packaging, and to support the proposed shelf life. {4}------------------------------------------------ ## DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/4/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
