Device Story

Acetabular liners fabricated from ultra-high molecular weight polyethylene (UHMWPE) infused with Vitamin E; modified manufacturing process achieves higher cross-linking (100 kGy). Used as components in total hip arthroplasty; implanted by orthopedic surgeons in clinical settings. Device serves as bearing surface in hip joint replacement; provides wear resistance through cross-linked material properties. Benefits patients by restoring joint function and addressing degenerative or traumatic hip conditions.

Clinical Evidence

No clinical data provided. Substantial equivalence based on non-clinical laboratory testing.

Technological Characteristics

Material: Ultra-high molecular weight polyethylene (UHMWPE) per ASTM F-648. Features: Vitamin E infusion; 100 kGy cross-linking process. Application: Acetabular liners for hip arthroplasty. Compatibility: Cemented and uncemented hip prosthesis systems.

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) requiring head involvement, or revision of failed total hip arthroplasty. Suitable for cemented and uncemented applications.

Regulatory Classification

Identification

A hip joint metal/polymer semi-constrained cemented 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 includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

Poly™ (Vitamin E) Acetabular Liners

Device Description: Biomet Manufacturing Corp. is modifying the manufacturing process of ultrahigh molecular weight polyethylene (UHMWPE) used in the fabrication of polyethylene acetabular components. The modified manufacturing process results in a higher cross-linked polyethylene. The highly cross-linked UHMWPE is infused with medical grade Vitamin E.

#### Intended Une:

- 1. Non-inflammatory degenerative ioint 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 using other techniques.
- 5. Revision of previously failed total hip arthroplasty.

Cemented and Uncemented Applications

Summary of Technologies: The intended use, indications, contraindications, and design specifications of the subject components remain identical to its predicate counterpart, with the exception of a manufacturing change. The raw material being utilized in the manufacture of both the subject and the predicate devices remains a ultra-high molecular weight polyethylene (UHMWPE) per ASTM F-648. The modifications to the manufacturing process of this polyethylene will be introduced in order to create a higher cross-linked polyethylene. The safety and effectiveness of this cross-linked polyethylene in acetabular applications are adequately supported by the substantial equivalence information, materials data, and testing results provided within this Premarket Notification.

Dear Ms. Johnson:

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. 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.

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