The Portland Cobalt Chrome Femoral Head has the following indications for use:
• The patient should be skeletally mature.
• The patient's condition should be due to one or more of the following:

  1. Osteoarthritis.
  2. Rheumatoid arthritis.
  3. Tumor conditions involving the upper third of the femur or of the Acetabular.
  4. Ankylosing spondylitis.
  5. Psoriatic arthritis.
  6. Old osteomyelitis - with a long infection-free period and a normal WBC, ESR and C-reactive protein.
  7. Non union of femoral neck fracture or avascular necrosis of the femoral head.
  8. Post-traumatic fracture/dislocation of the hip.
  9. Revision of an unsuccessful arthrodesis with either poor positioning or pain in the hip, or where low back pain or knee pain is becoming disabling.
  10. Revision of an unsuccessful cemented or un-cemented hip replacement, providing sufficient bone stock is present.

Device Description

The Portland Cobalt Chrome Femoral Head is provided as a single component. The device is manufactured from a cobalt chrome alloy and is available in various sizes. The internal bore of the femoral head is designed to taper lock (12/14) with the external male taper on a Portland Orthopaedics femoral hip stem providing articulation with a suitable acetabular module.

AI/ML Overview

I am sorry, but based on the provided text, there is no information about acceptance criteria or a study that proves the device meets any specific acceptance criteria.

The document is a 510(k) summary for the Portland Cobalt Chrome Femoral Head, which is a regulatory submission to the FDA. It primarily focuses on demonstrating "substantial equivalence" to existing legally marketed devices.

Here's what the document does include:

  • Description of the Device: Details on its material (cobalt chrome alloy), design (taper lock), and intended use (articulation with an acetabular module and femoral hip stem).
  • Indications for Use: A list of conditions for which the device is intended to be used (e.g., osteoarthritis, rheumatoid arthritis, certain hip fractures or revisions).
  • Substantial Equivalence Information: States that the device is substantially equivalent to cobalt chrome femoral heads from Biomet and Exacted due to similarities in design, intended use, material, and manufacturing.
  • Summary of Testing: Mentions that "Portland Orthopaedics, Ltd. has provided analytical and mechanical testing to demonstrate the substantial equivalence of and compliance to standards for the Cobalt Chrome Femoral Head." However, it does not provide any details about the specific tests performed, the acceptance criteria for those tests, or the results.

Therefore, I cannot populate the table or answer the specific questions about acceptance criteria, study design, sample sizes, ground truth, or expert involvement as this information is not present in the provided text.

Dear Ms. Duncan:

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.

§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.

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