510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.

Unknown
The Semi-Constrained Metal/Polymer Metatarsophalangeal Toe Joint Prosthesis (product code LZJ) is a surgically implanted orthopedic device used to replace the metatarsophalangeal joint of the toe in patients with severe arthritis or joint deformity, using a metal and polymer composite design. It is currently unclassified (Class U) with no assigned regulation number, and is reviewed under the Orthopedic (OR) panel. The device is flagged as an implant. As an unclassified device, its regulatory pathway has not been fully determined.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
