Fine Osteotomy™ is a system intended for open- and closed-wedge osteotomies, treatment of bone and joint deformities, fixation of fractures and malalignment caused by injury or disease, such as osteoarthritis, of the distal femur and proximal tibia. Fine Osteotomy disposable instrumentation is intended to assist in pre-operative planning and/or in guiding the marking of bone and/or guiding of surgical instruments in non-acute, non-joint replacing osteotomies around the knee. Fine Osteotomy is a patient-specific device.
Device Story
Fine Osteotomy is a patient-specific system for orthopedic surgery of the distal femur and proximal tibia. Input consists of patient CT images used to design custom bone plates, surgical planning guides, and resection instruments. The system transforms these images into 3D models via the 'Application Creator' software, which are then used to manufacture patient-specific, single-use cutting guides and implants. The device is used in clinical settings by surgeons to perform osteotomies and stabilize bone resections or fractures. The system includes titanium bone plates and screws, and nylon-12 resection guides. Surgeons use the patient-specific guides to mark bone and direct surgical instruments intra-operatively, ensuring the procedure matches the pre-surgical plan. The bone plates and screws provide mechanical fixation. The system benefits patients by providing anatomically matched implants and guides, potentially improving surgical accuracy and fixation stability compared to generic hardware.
Clinical Evidence
No clinical data provided. Evidence is based on bench testing, including mechanical performance evaluations (torsional strength, pull-out strength, static and dynamic cantilever bending resistance, and push-out tests) and software validation. Results demonstrated that the system meets or exceeds the performance of predicate devices.
Technological Characteristics
Materials: Wrought Titanium-6Al-4V ELI (ASTM F136-13) for plates/screws; additively manufactured Nylon-12 for resection guides. Principle: Patient-specific mechanical fixation and guided osteotomy. Connectivity: Standalone software for 3D model generation. Sterilization: Supplied clean, non-sterile. Software: Application Creator for manual conversion of medical images to 3D models.
Indications for Use
Indicated for patients requiring open- or closed-wedge osteotomies, treatment of bone/joint deformities, or fixation of fractures and malalignment of the distal femur and proximal tibia caused by injury or disease (e.g., osteoarthritis).
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.

|---------------------|
#### Fine Osteotomy™ is a system for planning osteotomies of the distal femur and proximal tibia, and for stabilizing the bone with bone screws and a patient-specific bone plate that fits the patient's anatomy " consists of patient-specific surgical planning and instrument guides designed from images of the patient-specific bone plate designed from the patient's images, compression and/or locking bone screws, and class 1 reusable manual instruments. The bone plate is a patient-specific, single-use implant; the surgical planning and instrument guides are patient-specific, single-use, and discarded after surgery. Fine Osteotomy™ is offered in three configurations: 1) as a system of patient specific implants and single use instruments for performing osteotomies and implanting hardware to stabilize the resection, 2) as patient specific single use instruments alone for performing osteotomies, and 3) as a patient specific bone plate and screws for stabilizing a bone resection or fracture.
When used as a system, Fine Osteotomy™ enables the surgeon to perform and stabilize the bone around the knee that matches the pre-surgical plan using the patient-specific cutting guides and bone plate. When the planning guides and resection instruments are used alone, Fine Osteotomy™ enables the surgeon to perform an osteotomy around the knee the presurgical plan using the patient-specific cutting guident's CT images. When the bone plate and screws are used alone. Fine Osteotomy™ enables the surgeon to stabilize fractured or resected bone per the patient's CT images in design of the Bodycad plate and use of the bone models intra operatively to guide placement of bone. The Fine Osteotomy System is provided clean, not sterile to the user.
This 510(k) submission is intended to notify the FDA of the mechanical locking system, the addition of new screw lengths, and option to use a new in-house for planning and cutting quide design in the Fine Osteotomy System, previously cleared in K240703.

### Indications for Use Comparison
No changes have been made to the Indications for Use statement for Fine Osteotomy™ in this submission.
## Technological Comparison
### 21 CFR 807.92(a)(6)
21 CFR 807.92(a)(5)
21 CFR 807.92(a)(5)
Fine Osteotomy" retains the same intended use and technological characteristics as the predicate devices K141796, and reference device K240703. This includes common design features and clinical indications such as locking and compression cortical bone screws, compression cancellous bone screws, and an opening wedge for mechanical support at the osteotomy site. Additionally, the devices share features like two or more holes positioned superior and inferior to the minimum strength requirements for supporting and stabilizing bone during and patient-specific bone resection guides and models to assist in bone resection and guide implant placement. Moreover, patient-spection instruments, and implants are utilized for both opening and closing wedge osteotomies in the tibia and femur.
In this submission, we have enhancal locking system to improve stability and reliability, ensuring a more secure and durable fixation of bone screws that aligns with the locking features of the predicate devices. We have also introduced additional screw lengths (75mm 80mm. 85mm. and 90mm) exclusively for the locking configuration, providing surgeons additional options for optimal fit and stabilization, and maintaining the principle of adjustable mechanical support found in the predicate devices. Furthermore, the introduction of Application Creator into the Osteotomy medical device manufacturing process enables the creation of patientspecific cutting guides by converting medical into 3D models manually. This integration complements existing design features while advancing the capability of the system to provice solutions based on individual patient anatomy. Fine Osteotomy" implants, single-use instruments are supplied clean but non-sterile, consistent with the predicate and reference devices. The comparison of design features with those of the claim of substantial equivalence for the subject, predicate, and reference devices, confirming that the intended use or safety profile of the device.
#### Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)
Non-Clinical Tests:
Mechanical Testing
- Torsional and Pull-Out Strength: Tests conducted on the locking screws and bone plates demonstrated mechanical strength,
exceeding the performance of predicate devices.
- Bending Resistance: The device was subjected to static and dynamic cantilever bending tests, which confirmed its enhanced structural integrity .
- Push-Out Test: Measure the axial force required to dislodge locking screws from the bone plates, crucial for osteotomy repair stability.
The mechanical testing, including torsional, pull-out tests, alongside software validation demonstrates that the Fine Osteotomy™ system meets all necessary performance and safety standards.

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.
