Intended Use

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

Device Story

Modular hip prosthesis components including acetabular liners and femoral head (size 32mm). Used in total hip arthroplasty to restore joint function. Surgeon implants components during orthopedic surgery. Constrained liners provide stability for high-dislocation-risk patients. Device functions as mechanical interface between femoral stem and acetabular shell; provides articulation and fixation. Benefits include reduced dislocation risk and restoration of hip mobility. No software or AI components.

Clinical Evidence

Bench testing only. No clinical or animal data required. Performance supported by mechanical testing including axial pull-out, lever-out, and vertical load fatigue tests, alongside engineering analysis comparing subject device to previously cleared G7 liners (K121874).

Technological Characteristics

Modular hip components. Materials: UHMWPE (ASTM F648), titanium alloy (ASTM F136) for constraining rings, wrought cobalt chrome (ASTM F1537) for femoral head. Mechanical fixation/articulation. Sterile, single-use. No software, electronics, or algorithms.

Indications for Use

Indicated for patients requiring total hip arthroplasty due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures (non-union, femoral neck, trochanteric) unmanageable by other techniques. Constrained liners indicated for primary/revision patients at high risk of dislocation (history of dislocation, bone loss, laxity, neuromuscular disease, intraoperative instability) where other options are exhausted.

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:

- K121874, G7 Acetabular System, Biomet, Inc. .
- . K030047, K043537 Ringloc Freedom Constrained Liners, Biomet, Inc.
- K870271 S-ROM Poly Dial Constrained Socket for Acetabular Cup, Joint Medical . Products (now owned by DePuy)

### Device Description

The G7 Acetabular System is a modular system, designed to provide numerous options for surgeons and patients in one compatible system. Further liner options are being added to the G7 Acetabular System which include: Neutral +5mm liner in ArComXL or E1; G7 Freedom Constrained Liners in two new profiles, the +5mm and the 10 Degree in E1. as well as a line extension to include G7 Freedom Neutral Liners in a size 32mm: and a new Femoral Constrained Head in Size 32mm (Cobalt Chrome, ASTM F1537).

### Intended Use and Indications for Use

- 1. Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis.
- 2. Rheumatoid arthritis.
- 3. Correction of functional deformity.
- 4. Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques.
- 5. Revision procedures where other treatment or devices have failed.

Porous acetabular shells and femoral stems are indicated for uncemented biological fixation. Non-coated or polyethylene components may be used with mating components that are indicated for either cemented or uncemented use.

### Additional indications for Biomet G7 Freedom Constrained Liners:

The Biomet G7 Freedom Constrained Liner is indicated for use as a component of a total hip prosthesis in primary and revision patients at high risk of dislocation due to a history of prior dislocation, bone loss, joint or soft tissue laxity, neuromuscular disease, or intraoperative instability, and for whom all other options to constrained acetabular components have been considered.

### Summary of Technological Characteristics

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

- Intended Use: The proposed G7 Freedom and Offset Liners. Freedom Head, ● Size 32 devices have the same intended use.
- Indications for Use: The proposed G7 Freedom and Offset Liners, Freedom Head, Size 32 devices have the same indications for use.
- . Materials: The proposed acetabular liners are manufactured from UHMWPE per ASTM F648. The proposed acetabular liners in both ArComXL and E1 utilize the same material and manufacturing processes as the predicate liners in K121874,

{5}------------------------------------------------

Image /page/5/Picture/1 description: The image shows the word "BIOMET" in a bold, sans-serif font. The letters are all capitalized and evenly spaced. The word is likely a logo or brand name.

the G7 Acetabular System. The constrained liners incorporate the use of titanium alloy (ASTM F136) constraining rings, identical to the predicates. The Freedom Head, Size 32, is manufactured from wrought cobalt chrome, ASTM F1537.

- . Design Features: The design features of the proposed liners are the same as those of the Biomet predicates and similar to the S-ROM Constrained Liners. The Freedom Head, Size 32, is similar to the previously cleared size 36 Freedom Head, with the exception of a design change to the circumferential flats to accommodate the smaller size.
- Sterilization: The proposed devices and the predicates are provided sterile via . the same sterilization methods for single use.

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

The mechanical tests and engineering analyses demonstrate the G7 Freedom and Offset Liners, Freedom Head, Size 32, are substantially equivalent to the predicate devices. No animal or clinical testing was required to support substantial equivalence. A description of the tests is located below.

- Axial Pull-out Test (Freedom Head)
- Lever-out Test (Freedom Head) .
- o Vertical Load Fatique Test (Poly Liners)

Since the internal design, materials and locking mechanism of the acetabular liners are the same as the G7 liners cleared in K121874, the non-clinical testing submitted for K121874 can be used as justification for the performance of the new G7 liners.

### Substantial Equivalence Conclusion

The proposed G7 Freedom and Offset Liners and the Freedom Head, Size 32mm, have the same intended use and identical or similar indications for use as the predicate devices. Performance test data and analyses demonstrate the devices to be as safe and effective as the legally marketed predicate devices, indicating the G7 Freedom and Offset Liners and the Freedom Head, Size 32mm, substantially equivalent to the predicates.
