Regulatory Classification
Identification
Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

{5}------------------------------------------------
#### EQUIVALENCE TO MARKETED DEVICE
The subject device is substantially equivalent in indications and design principles to the primary predicate device, the additional predicate devices, and the reference devices listed above. Provided at the end of this summary are tables comparing the Indications for Use Statements (IFUS) and the technological characteristics of the subject device, the primary predicate device, the additional predicate devices, and the reference devices.
The primary predicate device K013248 is in support of substantial equivalence in terms of comparable IFUS, plate designs (including use with locking and non-locking screws), screw designs, and materials. The primary predicate device K013248 also is in support of substantial equivalence in terms of comparison mechanical testing.
The additional predicate devices K092812, K011335, K083213, K000684 are in support of substantial equivalence in terms of comparable plate designs (including use with locking and non-locking screws), and for comparative mechanical testing.
The additional predicate device K091479 is in support of substantial equivalence in terms of comparable plate designs (including use with locking and non-locking screws), compatible screws and screw designs, and identical materials (unalloyed titanium conforming to ASTM F67 and titanium alloy conforming to ASTM F136).
The reference device K103332 is in support of substantial equivalence in terms of comparison mechanical testing.
The reference device K192297 is in support of substantial equivalence in terms of identical plate material (ASTM F67), and identical materials for the Class II accessories and instruments.
The reference device K191848 is in support of substantial equivalence in terms of identical plate material (ASTM F136), and for sterilization and shelf life for product provided sterile to the end user.
The subject device, the primary predicate device, the additional predicate devices, and the reference devices have the same intended use for internal fixation of bones including the lower extremity. The IFUS for K013248, K092812, K083213, K000684 include specific language referencing the tibia, fibula, or both.
Differences among the IFUS for the subject device, the primary predicate device, the additional predicate devices, and the reference devices include specific language not in the subject device IFUS referring to internal fixation of bones other than the lower extremity, or the use in osteopenic bone (K013248, K092812, K083213, K000684). The IFUS for the reference devices K103332, K192297, and K191848 include language referring to internal fixation of the upper extremity. These minor differences do not impact substantial equivalence because all IFUS express equivalent intended use for internal fixation of various bones.
The plates from the subject device and the plates cleared in K091479, K103332, K192297, and K191848 have the same technological characteristics, have similar design characteristics, include screw holes to accommodate locking and non-locking screws, and are made of identical materials.
The plates from the subject device, the primary predicate device K013248, and the additional predicate devices K092812, K011335, K083213, and K000684 have similar designs for specific anatomic locations and encompass a similar range of physical dimensions (overall length, and thickness).
{6}------------------------------------------------
The plates from the subject device are compatible with subject device screws and with Medartis AG screws cleared in K091479, and also are compatible with Medartis AG K-Wires cleared in K092038.
All of the subject device final finished components are manufactured in the same facilities using identical materials and identical manufacturing processes as used for the Medartis AG devices cleared in K091479. K103332, K192297, and K191848, and, therefore, are substantially equivalent to these devices regarding biocompatibility.
The subject device includes components that are provided non-sterile and components that are provided sterile. The subject device components that are provided non-sterile are packaged using the same materials, and are to be sterilized by the same methods as the Medartis AG devices cleared in K091479. K 103332, and K 192297. The subject device components that are provided sterile to the end user are packaged using the same materials, are to be sterilized by the same method, and have the same sterile barrier shelf life as the Medartis AG devices cleared in K191848.
The differences among the plates from the subject device, the primary predicate device, the additional predicate devices, and the reference devices include variations in the designs of the plates (number of designs, overall dimensions, placement of screw holes), and variations in the sizes of the compatible screws. The plates from the primary predicate device K013248 and from the additional predicate devices K092812, K011335, K083213, and K000684 are made of a different titanium alloy material compared to the subject device. These slight differences among the subject device, the primary predicate, and reference devices do not impact safety or effectiveness.
The subject device screws have similar designs and are made of the identical as the Medartis AG devices cleared in K091479 and K103332.
The subject device washer is made of the identical titanium alloy conforming to ASTM F136 as the subject device plates and screws and has a design similar to the Medartis AG washers cleared in K112560.
The subject device Class II accessories (trays and device-specific instruments) have similar designs and are made of identical materials as the Medartis AG Class II accessories and instruments previously cleared in K192297.
#### CONCLUSION
The subject device, the primary predicate device, and the reference device have the same intended use, have similar technological characteristics, and encompass a similar range of physical dimensions appropriate to the anatomy. The subject device and the primary predicate device are made of the identical material. The data included in this submission demonstrate substantial equivalence to the primary predicate device, the additional predicate devices, and the reference devices listed above.

1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
