Intended Use

The RingLoc® 36mm Liners and Modular Femoral Heads are intended for either cemented of uncemented use.

Device Story

RingLoc® 36mm Liners and Modular Femoral Heads are components for total hip arthroplasty; used in cemented or uncemented procedures. Liners are UHMWPE; femoral heads are Co-Cr-Mo alloy. Heads feature standard Biomet Type I taper with various neck lengths (-6mm to +12mm); +9mm and +12mm sizes include a skirt to maintain rotation point. Device replaces damaged hip joint surfaces to restore function and reduce pain. Operated by orthopedic surgeons in clinical/hospital settings.

Clinical Evidence

No clinical testing was necessary for determination of substantial equivalence. Evidence based on mechanical bench testing and published literature.

Technological Characteristics

Liners: ArCom® UHMWPE (ASTM F648). Femoral Heads: Wrought Co-Cr-Mo (ASTM F1537). Design: Modular hip prosthesis with Type I taper. Energy source: N/A (mechanical). Connectivity: N/A. Sterilization: Not specified.

Indications for Use

Indicated for patients with noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures (nonunion, femoral neck, trochanteric) unmanageable by other techniques, and for revision of failed total hip arthroplasty.

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).

Predicate Devices

• RingLoc® 32mm Liners (K970501)
• 32mm Modular Femoral Heads (K974558)

Dear Mr. Baker:

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. Iisting 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. You must
