Intended Use
1. Joint impairment from arthritis (rheumatoid, osteo and post traumatic). 2. Revision of failed femoral head replacements. 3. When alternative reconstructive techniques are not viable. 4. When arthrodesis is contraindicated. 5. Avascular necrosis or fracture of the femoral head. 6. Congenital defects that will allow adequate function of the system.
Device Story
26 mm CoCr femoral head and hooded polyethylene acetabular liner; components of ProForm and Provident Hip Systems. Designed to increase polyethylene thickness in smaller diameter acetabular cups. Manufactured from Co-Cr-Mo alloy and UHMWPE. Used by orthopedic surgeons in hip replacement procedures. Supplements existing 28 mm head/liner offerings. Provides articulation surface for hip arthroplasty; intended to restore joint function in patients with degenerative or traumatic hip conditions.
Clinical Evidence
Bench testing only. Fatigue testing of the stem and 26 mm head was satisfied under previously released 510(k) submissions. Liner testing was satisfied under previous 510(k) submissions.
Technological Characteristics
Materials: Co-Cr-Mo alloy and ultra-high molecular-weight polyethylene (UHMWPE). Components: 26 mm CoCr femoral head and hooded acetabular liner. Design modification: Reduced head size to increase polyethylene thickness in smaller diameter acetabular cups. System: Orthopedic hip implant components.
Indications for Use
Indicated for patients with joint impairment due to rheumatoid, osteoarthritis, or post-traumatic arthritis; revision of failed femoral head replacements; avascular necrosis or fracture of the femoral head; or congenital defects where alternative reconstructive techniques are not viable or arthrodesis is contraindicated.
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).

## 26 MM CAST CoCr HEAD AND POLYETHYLENE ACETABULAR SHELL LINER
## Summary of Safety and Effectiveness Information Upon Which The Substantial Equivalence Determination is Based [510(k) Summarv]
The 26 mm CoCr Head and Hooded Liner are manufactured from biocompatible materials: Co-Cr-Mo alloy and ultra-high molecular-weight polyethylene (UHMWPE). These materials are in current use in numerous hip systems and their use has been established through many years of successful clinical application.
Fatigue testing of the stem and 26 mm head was satisfied under previously released 510(k) submissions. Likewise, the liner testing was satisfied under previous 510(k) submissions since only the I.D. has been changed.
A smaller CoCr head with appropriate liner was manufactured to increase polyethylene minimal thickness in the smaller diameter acetabular cups. These components will supplement 28 mm CoCr heads and liners already released in the ProForm and Provident Hip Systems.

Dear Mr. Stevens:
We have reviewed your Section 510(k) notification of intent to market the device referenced above, and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, market the device subject to the general control provisions of the Act. The general control 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General Regulation (21 CFR Part 820), and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA, finding of substantial equivalence of your device to a legally marketed predicate device, results in a classification for your device and thus, permits your device to proceed to the market.
