Intended Use

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. Acetabular shells and femoral stems with porous coatings 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. 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.

Device Story

Modular acetabular system for total hip arthroplasty; provides surgeons with multiple shell, liner, and head options. Components include titanium alloy shells with porous plasma spray coating, UHMWPE liners (neutral, high wall, or face-changing), and cobalt chrome femoral heads. System includes constrained liner/head options for high-dislocation-risk patients. Used in clinical/OR settings by orthopedic surgeons. Device replaces damaged hip joint surfaces to restore function and reduce pain. System compatibility extends to existing Biomet ceramic heads and femoral stems. Output is a reconstructed hip joint assembly; clinical decision-making relies on surgeon assessment of patient anatomy, bone quality, and stability requirements.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by extensive bench testing, including poly push-out, lever-out, torque-out, rim impingement, fatigue testing, range-of-motion studies, screw pull-through/torsional properties, and metal head fretting/corrosion analysis.

Technological Characteristics

Modular hip prosthesis. Materials: Titanium alloy (ASTM F136) shell, Porous Plasma Spray coating (ASTM F1580), UHMWPE liners (ASTM F648, ArComXL® or E1®), Cobalt chrome femoral heads (ASTM F1537). Features: Solid/limited hole shell designs, neutral/high wall/face-changing liners, constrained liner options. Mechanical fixation via uncemented porous coating or cemented techniques. No software or electronic components.

Indications for Use

Indicated for patients with non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, proximal femur fractures (non-union, femoral neck, trochanteric), or revision needs. Constrained liners indicated for primary/revision patients at high risk of dislocation (prior dislocation, bone loss, laxity, neuromuscular disease, intraoperative instability).

Regulatory Classification

Identification

A hip joint metal/polymer constrained cemented or uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device prevents dislocation in more than one anatomic plane and has components that are linked together. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular component made of ultra-high-molecular-weight polyethylene with or without a metal shell, made of alloys, such as cobalt-chromium-molybdenum and titanium alloys. This generic type of device is intended for use with or without bone cement (§ 888.3027).

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Hip Joint Metal/Polymer Constrained Cemented or Uncemented Prosthesis.”

#### Acetabular Shells:

Porous Plasma Spray (PPS®) RingLoc®+ Acetabular System, K093235 (Biomet) Reflection Acetabular Cup System, K033442 (Smith and Nephew) Continuum Acetabular System, K103662 (Zimmer)

#### Device Description:

The G7™ Acetabular System is a modular system, designed to provide numerous options for surgeons and patients in one compatible system. The titanium alloy (ASTM F136) shell is available in both a solid shell and limited hole design, with an apical hole and plug. The outer diameter of the shells is coated with Biomet's Porous Plasma Spray (ASTM F1580). The acetabular liners are manufactured from UHMWPE (ASTM F648) as ArComXL® or E1® (UHMWPE infused with vitamin E) and available in a Neutral, High Wall, or Ten Degree Face Changing design. Additionally, the system has provided for a constrained liner and head when such an option is required. The Biomet Freedom" product line has added a 32mm Freedom" head (cobalt chrome, ASTM F1537) to its offerings, as well as a new series of constrained liners (E1®, ASTM F648) designed for compatibility with the G7™ shells. A new line of cobalt chrome (ASTM F1537) femoral heads in varying sizes and neck lengths, with either a Type 1 or 12/14 taper, has been added to the system. The system is compatible with Biomet® ceramic heads and femoral stems.

#### Indications for Use:

- 2. Rheumatoid arthritis.
- 3. Correction of functional deformity.
- Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with 4. head involvement, unmanageable by other techniques.

#### Summary of Technologies:

The technological characteristics of the proposed device are the same as or similar to the predicates. The G7™ acetabular shells are similar in design, dimensions, and intended use to their Biomet predicate, K093235, but have incorporated a different locking mechanism, which is also similar to legally marketed predicates, K091508 and K103662. The acetabular liners are made of the same material as their predicates, and use previously cleared liner types, sizes and designs. The additional constrained head is a line extension to the Biomet Freedom™ constrained heads, and the constrained liners use the same design principles as the Freedom liner predicate, K030047. The cobalt chrome femoral heads are very similar to the Biomet predicate, K911684.

#### Non-Clinical Testing:

The following testing has been completed to support substantial equivalence: v

- Poly Push Out .
- Poly Lever Out .
- Poly Torque Out .
- Poly Rim Impingement .
- Poly Deformed Cup Push Out .
- Poly Deformed Cup Lever Out
- Poly Fatigue, Lever Out �
- Poly Constrained Liner Rim Impingement and Lever Out Testing .
- Range-of-Motion Study (Poly) .
- Poly Deformed Cup Push In .
- . Freedom Head Pull Out of Constrained Liner
- Screw Pull Through �
- Screw Torsional Properties .
- Torque Curve for MIM Screw Hole Plugs .
- Verification of Insertion Torque and Measurement of Torque Out .

#### Justifications:

- Poly Wear Simulator .
- Metal Head Justification .
- . MRI Justification
- Metal Head Axial Head Pull Off .
- Metal Head Fretting/Corrosion ●

#### Clinical Testing:

None provided as a basis for substantial equivalence.

Testing demonstrates that the modifications made to the G7™ Acetabular System do not introduce any new risks of safety or efficacy, and that the G7™ Acetabular System is substantially equivalent to the predicates.
