Intended Use

The Zimmer Biomet 12/14 CoCr Femoral Heads are intended for use in total and hemi arthroplasty* in primary and revision patients. Refer to the acetabular system and femoral stem package inserts for the full description of indications for the construct. * Hemi-Arthroplasty indication is for use with Bipolar Systems only. The Zimmer Biomet 12/14 CoCr Freedom® Heads are intended for primary or revision patients at high risk of hip dislocation due to a history of prior dislocation, bone loss, soft tissue laxity, neuromuscular disease, or intra-operative instability and for whom all other options to constrained acetabular components have been considered. Refer to the acetabular system and femoral stem package inserts for the full description of indications for the construct.

Device Story

Zimmer Biomet 12/14 CoCr Femoral Heads and Freedom® Heads are orthopedic implants used in hip arthroplasty. The devices consist of cobalt-chromium-molybdenum alloy (CoCrMo) femoral heads designed to mate with tapered femoral stems. They function as the articulating component of a hip prosthesis, replacing the femoral head to restore joint function. The Freedom® Head variant provides additional stability for patients at high risk of dislocation. These devices are implanted by orthopedic surgeons in a clinical/hospital setting. The output is a mechanical joint surface that facilitates hip movement and stability. Clinical benefit includes restoration of hip joint mobility and reduction of dislocation risk in high-risk patients.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by non-clinical bench testing, including pull-off testing, accelerated corrosion fatigue, and head fatigue testing.

Technological Characteristics

Materials: Cobalt-chromium-molybdenum alloy (CoCrMo) per ISO 5832-12:2007 and ASTM F1537-11. Design: Femoral heads with 12/14 taper interface for femoral stems. Sterilization: Identical to predicate. No software or electronic components.

Indications for Use

Indicated for primary or revision total/hemi-arthroplasty patients. Freedom® Heads specifically indicated for patients at high risk of hip dislocation (history of dislocation, bone loss, soft tissue laxity, neuromuscular disease, or intra-operative instability) where other constrained options are unsuitable.

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.

Dear Dean Heit:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

# Summary of Technological Characteristics:

The rationale for substantial equivalence is based on consideration of the following characteristics:

- Intended Use: Equivalent to predicate(s).
- Indications for Use: Identical to predicate(s). ●
- Materials: Identical to predicate(s).
- Design Features: Both the subject and predicate devices mate with a variety of femoral stems equipped with tapered necks. The variety of head diameters and neck configurations is equivalent although the subject device is available in a larger range of sizes.
- Sterilization: Identical to predicate. 0

## Summary of Performance Data (Nonclinical and/or Clinical)

#### Non-Clinical Tests: ●

- Pull Off Testing. O
- Accelerated Corrosion Fatigue. O
- Head Fatigue. O
- Resistance to Wear and Head Retention were O considered.
- Clinical Tests: ●
- o N/A

# Substantial Equivalence Conclusion

The subject device has the same intended use and equivalent indication for use as the predicate devices. The subject device is made of the identical material using a equivalent manufacturing process as the primary predicate device. In addition, the subject device has equivalent technological characteristics to the predicates and reference device. The performance data and analyses demonstrate that:

- any differences do not raise new questions of o safety and effectiveness; and
- the proposed device is at least as safe and O effective as the legally marketed predicate devices.
