The Proximal Femoral Module and Distal Femoral Module of the GMRS may be used together, or with the components of the MRS, in replacement of the total femur. Indications and contraindications for this type of replacement are listed below: # Indications Femoral and/or proximal tibial replacement and total femoral replacement in Oncology cases where radical resection and replacement of bone is required, and in limb salvage procedures where radical resection and replacement of the bone is required. Limb salvage procedures would include surgical intervention for severe trauma, failed previous prosthesis, and/or Oncology indications. #### Contraindications #### As related to Bone Tumors A. Not all bone tumors may be treated successfully by segmental resection. Any condition that may have already resulted in either local or distant spread of the tumor may be a contraindication. Examples of such conditions include: - . pathological fracture; - . overt infection; - . inopportune placement of biopsy incision; and, - rapid disease progression beyond a respectable margin. . - As related to Failed Previous Prosthesis and Trauma B. - Any active or suspected latent infection in or about the hip joint. ● - Any mental or neuromuscular disorder which would create an unacceptable risk of . prosthesis instability, prosthesis fixation failure, or complication in postoperative care. - Bone stock compromised by disease, infection, or prior implantation that cannot . provide adequate support and fixation of the prosthesis. {2}------------------------------------------------ Ka.3087 page 3 of 4 For the use of GMRS Press Fit stems with PureFix™ HA Coating, the following additional contraindication should be noted: - Inadequate bone stock to allow the use of a press fit stem . The Proximal Femoral Module of the GMRS is intended to be used in a cemented or press fit mode. The components of the Distal Femoral/Proximal Tibial Module are intended to be used with bone cement. ## Device Description The GMRS is comprised of a number of components that are intended to be used in conjunction with each other, or in conjunction with components of Howmedica Osteonics' Modular Rotating Hinge Knee, Kinematic Rotating Hinge Knee, and/or the Modular Replacement System. There are three modules of the GMRS: - Proximal Femoral Module . - . Distal Femoral/Proximal Tibial Module - . Total Femur Each of these modules is comprised of different components. The modules, and their individual components, are described below: #### Proximal Femoral Module The Proximal Femoral Module of the GMRS contains the following components: - . Proximal Femoral Components - Extension Pieces . - . GMRS Press Fit Stems with PureFix™ HA ## Distal Femoral/Proximal Tibial Module The Distal Femoral/Proximal Tibial Module of the GMRS contains the following new components: - Distal Femoral Components . - Extension Pieces (as described in the section above) . - Small bushings {3}------------------------------------------------ K023087 page 4 of 4 - Small Axle ● - Proximal Tibial Component . - Proximal Tibial Inserts . - . Proximal Tibia Rotating Components #### Total Femur Replacement of the total femur is accomplished by combining the following components of the GMRS: - Proximal Femoral Component . - . Extension Pieces - Connection Pieces ● - Distal Femoral Component (with appropriate bushings, axle, etc.) . - . Proximal Tibial Component (with appropriate tibial rotating component, tibial insert component) Equivalent products include: - 1. Modular Replacement System -Howmedica Osteonics Corp. - Distal Stems of the Restoration™ Hip System Howmedica Osteonics Corp. 2. - Modular Rotating Hinge Knee System Howmedica Osteonics Corp. 3. - 4.

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set {5}------------------------------------------------ # Page 2 - Mr. William J. Cymbaluk forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
