Intended Use

The Trabecular Metal Acetabular Augment System is intended to provide the orthopedic surgeon with a prosthetic alternative to structural allograft in cases of segmental acetabular deficiencies.

Device Story

Trabecular Metal Acetabular Augments serve as prosthetic alternatives to structural allograft for managing moderate to large-sized segmental acetabular defects during hip reconstruction. Devices feature truncated hemispherical geometry with integral flanges (buttress/column-buttress types) or act as space/void fillers (shim types). Used by orthopedic surgeons in clinical settings during revision acetabular surgery to bridge gaps between bone and reconstructive hardware. Augments provide structural support for acetabular components, potentially improving patient outcomes in complex revision cases.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Constructed of Trabecular Metal; truncated hemispherical geometry with integral flanges; available in multiple sizes/geometries for acetabular reconstruction; non-software device.

Indications for Use

Indicated for orthopedic surgeons to treat patients with segmental acetabular deficiencies as a prosthetic alternative to structural allograft.

Regulatory Classification

Identification

A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.

### 510(k) SUMMARY OF SAFETY AND EFFECTIVENESS

Trabecular Metal Acetabular Augments Submitter Name: Zimmer Trabecular Metal Technology, Inc. (Z-TMT) Submitter Address: 80 Commerce Drive Allendale, New Jersey 07401-1600 Contact Person: Robert A Poggie Phone Number: [phone] X 122 Fax Number: [phone] Date Prepared: April 13, 2006 Device Trade Name: Trabecular Metal Acetabular Augments Device Common Acetabular augmentation devices for total hip replacement Name: acetabular components Classification Number: 21 CFR § 888.3358 Substantial The term "substantial equivalence" as used in this Equivalence: 510(k) notification is limited to the definition of substantial equivalence found in the Federal Food, Drug and Cosmetic Act, as amended and as applied under 21 CFR 807, Subpart E under which a device can be marketed without premarket approval or reclassification. A determination of substantial equivalency under this notification is not intended to have any bearing whatsoever on the resolution of patent infringement suits or any other patent matters. No statements related to, or in support of substantial equivalence herein shall be construed as an admission against interest under the US Patent Laws or their application by the courts. Device Description: Trabecular Metal Acetabular Augments provide an alternative to structural allograft for augmenting moderate to large-sized segmental acetabular defects encountered in acetabular reconstruction. The Trabecular Metal Buttress and Column-Buttress Augments possess a truncated hemispherical geometry with integral flanges. The Shim Augments are space / void filler and bridge gaps between bone and other acetabular reconstructive hardware. These devices are available in several sizes and geometries to accommodate the wide range and location of bone deficiencies often encountered in revision acetabular surgery.

### Dear Dr. Poggie:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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
