The OSTEOTEC Silicone Finger Implant is a single piece flexible joint replacement implant for the metacarpophalangeal (MCP) joint and proximal interphalangeal (PIP) joints in the hand; commonly due to rheumatoid arthritis or osteoarthritis.

Device Description

The one-piece device consists of a specifically designed, central, flexible hinge attached to an elongated rectangular-based pyramid stem on either side. The stems insert into the intramedullary canals of the metacarpals and/or phalanges and have a slight surface texture.

The OSTEOTEC Silicone Finger Implant is manufactured from implant grade silicone. It is available in eleven, evenly scaled sizes to meet various anatomical requirements.

The OSTEOTEC Silicone Finger Implant is not designed for use with any other devices. The implant has dedicated instrumentation which is required to prepare the bone for the implant and sizers to ensure that the correct size of product is used.

AI/ML Overview

This document describes the Osteotec Silicone Finger Implant, a joint replacement implant. However, the provided text does not contain information about acceptance criteria or a study proving that a device meets such criteria in terms of performance metrics like sensitivity, specificity, accuracy, or any other statistical measures often associated with AI/ML medical devices.

The document is a 510(k) premarket notification for a medical device and focuses on establishing substantial equivalence to legally marketed predicate devices, primarily based on material, design, and intended use. The testing discussed ("dynamic mechanical properties," "static mechanical properties," "drop testing," "shelf life," and "instrument tray validation") pertains to the physical and functional characteristics of the implant and its packaging, not to the performance of an AI/ML system.

Therefore, I cannot fulfill your request for the specific details about acceptance criteria and a study proving device performance as described in your prompt, because this information is not present in the provided text.

Dear Ms. Clinton-Parker:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

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

Section 5 OSTEOTEC Silicone Finger Implant 510(k)

Clastogenicity has been assessed in a mammalian system to provide data to further support the biocompatibility of the device.

Assessments of the dynamic mechanical properties, of the subject and predicate devices, via side by side flexion testing to 10 million cycles, (Size 6 and Size 00) were conducted.

Assessments of the static mechanical properties, of the subject and predicate devices, via side by side static testing of the bulk materials, (Nusil MED 4757 and Nusil MED 4755), were conducted.

Drop testing has been performed to ensure that the packaging developed for the OSTEOTEC Silicone Finger is suitable and can maintain its sterile barrier throughout storage and distribution.

A shelf life of 5 years has been established for the OSTEOTEC Silicone Finger Implant based on functional testing after sealed and irradiated packages were stored in a recommended condition for a period greater than 6 years.

The instrument tray has been validated to perform effectively during cleaning, steam sterilization and drying time.

Based on the results from the above test data it is concluded that the OSTEOTEC Silicone Finger Implant is substantially equivalent to the above named predicate devices.
