Intended Use
1. Noninflammatory 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. 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.
Device Description
The G7™ Finned Acetabular Shell is a medical device intended to be used as part of a hip joint replacement in Total Hip Arthroplasty procedure by qualified surgeons in the field of orthopaedics. The G7™ Finned Acetabular Shell is utilized to replace the acetabulum, and will be used in conjunction with the existing G7 Acetabular Cup bearing system (K121874), instruments and modular femoral system. The G7™ Finned Acetabular Shell will have the same internal geometry, liner locking system and PPS coating as the G7 Acetabular Cup System Shells (K121874) but will feature fins to provide improved primary fixation and anti-rotational stability.
More Information

No
The document describes a mechanical hip implant component and its intended use, with no mention of AI or ML in its design, function, or performance evaluation.

No

Explanation: A therapeutic device is designed to treat or alleviate a medical condition. While this device is part of a hip replacement and helps correct functional deformity, it is a replacement component rather than a device that actively treats the disease itself. Its function is primarily structural and restorative of anatomy, rather than actively therapeutic in the sense of delivering treatment or therapy.

No
Explanation: The device is described as a component of a hip joint replacement, specifically an acetabular shell, used in Total Hip Arthroplasty. Its intended use is for treatment and correction of conditions like noninflammatory degenerative joint disease, rheumatoid arthritis, non-union of fractures, and revision procedures, not for diagnosing them.

No

The device description clearly states it is a physical medical device, an acetabular shell, intended for surgical implantation as part of a hip replacement.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Description: The device described is a G7™ Finned Acetabular Shell, which is a physical implant used in hip replacement surgery. It is surgically implanted into the patient's body.
  • Intended Use: The intended use is to replace the acetabulum as part of a total hip arthroplasty procedure. This is a surgical intervention, not a diagnostic test performed on a sample outside the body.

The information clearly indicates a surgically implanted medical device used for treatment and correction of anatomical issues, not for diagnosing conditions using in vitro methods.

N/A

Intended Use / Indications for Use

  1. Noninflammatory 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.

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.

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
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.(b)
Classification. Class II.
