Indications for Use
The I.B.S.TM compression and neutralization osteosynthesis screws are intended for: - The fixation of arthrodesis, osteotomies or fractures of long or short bones of the upper and lower limbs - Osteosynthesis requiring a mono or bicortical compression The size of the chosen screw should be adapted to the specific indications.
Device Story
I.B.S. osteosynthesis screws are metallic bone fixation fasteners used for arthrodesis, osteotomies, or fracture fixation in upper and lower limbs. These are cannulated, self-tapping, and self-drilling screws available in compression and neutralization designs. The device is surgically implanted into bone by a physician. The screws provide mechanical stability to bone segments, facilitating healing. This submission represents a range extension of existing screw lengths and thread configurations for 6.5mm and 2.5mm diameter screws. The device is intended for long-term implantation (>30 days).
Clinical Evidence
Bench testing only. Dimensional comparison and mechanical behavior analysis performed per ASTM F543 (torque to failure, insertion torque, axial pullout strength, self-tapping performance). Pyrogen testing conducted via LAL test per ANSI/AAMI ST72:2011.
Technological Characteristics
Cannulated, self-tapping, self-drilling metallic bone screws. Material: Titanium alloy Ti6Al4V per ISO 5832-3 and ASTM F136. Diameters: 2.5mm and 6.5mm. Sterilization: Not specified.
Indications for Use
Indicated for fixation of arthrodesis, osteotomies, or fractures of long or short bones of upper and lower limbs; requires mono or bicortical compression. Applicable to patients requiring bone fixation.
Regulatory Classification
Identification
A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

| Comparison of<br>Technological<br>characteristics | The technological characteristics of the modified I.B.S.TM osteosynthesis screws are equivalent to the characteristics of predicate devices in terms of design, size range, raw material. All these implants have the following features:<br>- Insertion into bone: The modified I.B.S.TM osteosynthesis screws and all predicate devices are intended for surgical implantation into bone for longer than 30 days.<br>- Design: Predicate devices have similar design as the modified I.B.S.TM osteosynthesis screws. They all are cannulated, self-tapping and self-drilling screws with either a compression or a neutralization design.<br>- Indications for use: Predicate devices have equivalent indications for use as the modified I.B.S.TM Osteosynthesis screws in terms of fixation of arthrodesis, osteotomies or fractures of long or short bones of the upper and lower limbs. These non-identical indications are equivalent and do not impact the safety and effectiveness of the modified I.B.S.TM Osteosynthesis screws.<br>- Equivalent size range: Predicate devices have comparable size range of as the modified I.B.S.TM Osteosynthesis screws. The slightly difference of the predicates does not impact the safety and effectiveness of the modified I.B.S.TM Osteosynthesis screws.<br>The length discrepancies of the I.B.S.TM osteosynthesis screw predicate (K131920) in comparison to the modified I.B.S.TM Osteosynthesis screws 6.5mm diameter are the reason of this Special 510(k) submission and do not impact the safety and effectiveness of the modified I.B.S.TM Osteosynthesis screws 6.5mm diameter, as it is explained in the "Performance Testing" section.<br>- Material: The modified I.B.S.TM osteosynthesis screws have identical raw material, when compared to the predicate: all are manufactured from Titanium alloy Ti6Al4V, according to ISO 5832-3 and ASTM F136 standards. |
| Substantial<br>Equivalence<br>Summary | As described above, the modified I.B.S.TM osteosynthesis screws<br>have similar technological characteristics when compared to the<br>predicate devices. |
| Summary<br>Performance<br>Data | The dimensional modifications between the unmodified I.B.S.TM<br>osteosynthesis Screws, K131920, and the modified I.B.S.TM<br>osteosynthesis Screws have been evaluated through dimensional<br>comparison with predicate devices and analysis of the impact on<br>mechanical behavior based on standard ASTM F543.<br>This standard describes methods to assess the torque to failure,<br>insertion torque, axial pullout strength, and self-tapping<br>performance of screws. No new bench testing was deemed<br>required to assess the torsional properties, driving torque and<br>axial pullout of the modified I.B.S.TM osteosynthesis screws.<br>Therefore, the subject device was demonstrated to be as safe<br>and effective as the above predicates |
| Pyrogen testing | The method used to make the determination that the device<br>meets pyrogen limit specification is the Limulus Amebocyte<br>Lysate (LAL) test in accordance with ANSI/AAMI<br>ST72:2011: Bacterial endotoxins – Test methods, routine<br>monitoring and alternative to batch testing. |
| CONCLUSION | Based on the evaluations and the results of the dimensional<br>comparison performed, the design and indications of the<br>modified I.B.S.TM osteosynthesis screws are substantially<br>equivalent to the predicate devices identified in the 510(k)<br>submission. No new materials or processes are used in the<br>development of this implant.<br>The modified I.B.S.TM osteosynthesis screws are acceptable<br>for the application. |

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
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.
