Intended Use

Indications for use of the ConsensusTM Hip System or UNISYN™ Hip System

  • A) Significantly impaired joints resulting from rheumatoid, osteo, and post-traumatic arthritis.
  • B) Revision of failed femoral head replacement, cup arthroplasty or other hip procedures.
  • C) Proximal femoral fractures.
  • D) Avascular necrosis of the femoral head.
  • E) Non-union of proximal femoral neck fractures.
  • F) Other indications such as congenital dysplasia, arthrodesis conversion, coxa magna, coxa vara, coxa vara, coxa valga, developmental conditions, metabolic and tumorous conditions, osteomalacia, osteoporosis, pseudarthrosis conversion, and structural abnormalities

Acetabular components are indicated for cemented and cementless use. Consensus femoral stems are indicated for cemented and cementless use. UniSyn femoral stems are indicated for cementless use only. HA coated implants are indicated for cementless use only.

Device Description

The Consensus Hip 36mm CoCrMo (ASTM F799 or ASTM F1537) femoral head is offered with four different offsets, -5mm, neutral, +5mm and +10mm. Other than size, it incorporates no new design features. Female head taper is identical to the head taper design for the cleared devices.

The 36mm acetabular insert is offered in sizes 54 - 68 (2 mm increments), in neutral, 10 and 20 degree hooded configurations. Material for all 36mm insert sizes is crosslink UHMWPE (ASTM F648). Hooded configurations incorporate a titanium alloy x-ray marker (Ti 6Al-4V ELJ ASTM F136). Insert locking detail of the subject device is identical to the locking detail of the cleared devices.

AI/ML Overview

The provided text is a 510(k) summary for a medical device: a 36mm CoCrMo Femoral Head and Acetabular Insert for the Consensus Hip System. This document focuses on demonstrating substantial equivalence to previously cleared devices, rather than presenting a study with acceptance criteria and a detailed performance evaluation of a new AI/software device.

Therefore, the information requested in your prompt (acceptance criteria, study details, sample sizes, ground truth, expert qualifications, adjudication, MRMC studies, standalone performance, training set details) is not applicable to this type of regulatory submission.

This 510(k) relies on the following for demonstrating safety and effectiveness:

  • Comparison to Cleared Device: The primary argument is that the new 36mm femoral head and acetabular insert are substantially equivalent to existing, legally marketed devices. The only change is the addition of a new size (36mm).
  • Intended Use, Material, Design Features, and Type of Interface: These aspects of the new components are stated to be identical or highly similar to predicate devices.
  • Materials Data: The submission mentions "materials data" was provided to support safety and effectiveness, implying biocompatibility and mechanical properties testing relevant to the materials used (CoCrMo and UHMWPE) rather than clinical performance data.

In summary, this document does not contain the kind of study design and performance data typically associated with evaluating a novel AI/software medical device against specific acceptance criteria.

Consensus Hip System - Addition of a 36mm CoCrMo Femoral Head and Acetabular Insert

The 36mm acetabular insert is offered in sizes 54 - 68 (2 mm increments), in neutral, 10 and 20 degree hooded configurations. Material for all 36mm insert sizes is crosslink UHMWPE (ASTM F648). Hooded configurations incorporate a titanium alloy x-ray marker (Ti 6Al-4V ELJ ASTM F136). Insert locking detail of the subject device is identical to the locking detail of the cleared devices.

Comparison to Cleared Device:

The only change made to the previously cleared Consensus femoral heads and liners is the addition of a new size, the 36 mm femoral head and a series of compatible acetabular inserts, including 10 and 20 degree hooded configurations.

Substantial Equivalence Information

The intended use, material, design features and type of interface of the 36mm femoral head and inserts are substantially equivalent to predicate Hayes Medical and competitive devices. The safety and effectiveness of the subject 36mmm head and inserts are adequately supported by the substantial equivalence information and materials data provided within this Special 510(k) submission.

Dear Mr. Rose:

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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set

forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 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.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120 Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807,97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.

§ 888.3360 Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis.

(a)
Identification. A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.(b)
Classification. Class II.
