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.

## Legally marketed devices to which substantial equivalence is claimed:

- G7 Dual Mobility System (K150522)
- E1 Avantage Heads (K101336)
- ArComXL Active Articulation Heads (K110555)

## Device Description

The G7 Dual Mobility System and Active Articulation System are dual articulation systems wherein there are two articulating surfaces in the same joint space. The systems include an Active Articulation polyethylene (UHMWPE) bearing which is assembled over a femoral head. The femoral head articulates on the inner, concave surface of the bearing. The resultant assembly then articulates within a metal liner (G7 Dual Mobility System) or acetabular shell (Active Articulation System). The G7 Dual Mobility and Active Articulation Systems are designed for both primary and revision surgeries, where all device components associated with the wear couple are removed and replaced.

The Zimmer cobalt chrome and ceramic femoral heads are proposed as compatible femoral head components. As part of this additional compatibility, legally marketed Zimmer stem combinations will be included for system compatibility.

## Intended Use and Indications for Use

- 1. Non-inflammatory degenerative joint disease including osteoarthritis and avascular
- Rheumatoid arthritis. 2.
- 3. Correction of functional deformity.
- Treatment of non-union, femoral neck fracture, and trochanteric fractures of the 4. proximal femur with head involvement, unmanageable by other techniques.
- 5. Revision of previously failed total hip arthroplasty.
- 6. Dislocation risks.

The Active Articulation Hip Bearings and G7 Metal Liners are single-use implants, intended for uncemented applications.

#### Summary of Technological Characteristics

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

- Intended Use: The intended use of the proposed compatibility of the G7 Dual Mobility . and Active Articulation Systems is identical to the intended use of the predicates. The intended use of the predicates is not impacted by the proposed expanded compatibility.
- Indications for Use: The indications for use of the proposed compatibility of the G7 Dual ● Mobility and Active Articulation Systems is identical to the indications for use of the predicates. The indications for use of the predicates is not impacted by the proposed expanded compatibility.
- . Materials: The materials of the proposed compatible components of the G7 Dual Mobility and Active Articulation Systems are identical to the materials of the predicates. The materials of the predicates are not impacted by the proposed expanded compatibility.
- . Design Features: The design features of the proposed compatible components of the G7 Dual Mobility and Active Articulation Systems are identical to the design features of the predicates. There have been no design changes to the originally cleared predicate devices as a result of the proposed expanded compatibility.
- Sterilization: Sterilizaiton methods and processes of the proposed compatible ● components of the G7 Dual Mobility and Active Articulation Systems is identical to the sterilization methods and processes of the predicates. Sterilization methods and processes are not impacted by the proposed expanded compatibility. Subject and predicate devices are provided sterile, single-use only.

#### Summary of Performance Data

Results from performance tests and engineering analyses demonstrate the subject G7 Dual Mobility and Active Articulation Systems, including proposed new compatible components, remain substantially equivalent to the systems cleared in K150522, K101336 and K110555. No

animal or clinical testing was required to support substantial equivalence. A description of the tests performed on the proposed compatibility is as follows:

- Wear Justification Reports ISO 7206-2: 2011 ●
- Interference Fit Analyses
- Push-in, Pull-out, Lever-out Analysis - ASTM F1820-13
- Range of Motion Analyses – ISO 21535:2007

## Substantial Equivalence Conclusion

The proposed G7 Dual Mobility System and Active Articulation System have the same intended use and indications for use as the predicates. Performance test data and analyses demonstrate the proposed expanded compatibility is as safe and effective and is substantially equivalent to the legally marketed predicates.
