Device Story
Internal bone fixation system consisting of anatomically contoured titanium plates and locking screws; used for small bone reconstruction, corrective osteotomies, and fracture fixation in metacarpals and metatarsals. System functions by engaging locking screws into threaded plate holes to create a fixed-angle construct; stabilizes bone fragments and maintains alignment to promote healing. Used in clinical settings by orthopedic surgeons. Healthcare providers select appropriate plate and screw components based on patient anatomy and fracture/osteotomy site. Output is a rigid mechanical construct that provides structural support to bone during the healing process. Benefits include stabilization of bone fragments and maintenance of alignment.
Clinical Evidence
Bench testing only. Mechanical testing performed per ASTM F543 (screws) and non-standard construct-level testing (plates) using synthetic bone models with simulated osteotomies. Testing included static loading (5 mm/min) and cyclic loading (0-31 N at 0.5 Hz for 1,000 cycles). Results compared against predicate devices and literature-supported physiological benchmarks to confirm equivalent structural integrity. No clinical data provided.

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.

| Device Description Summary | | 21 CFR 807.92(a)(4) |
| The APS Spear Locking Plate System (2.4mm locking screw (0824-4302-xx); 2.7mm continuous locking screw (0827-2302-xx); Spear locking plate (1300-0x05-xx); and Spear locking plate ii (1301-0x05-xx)) is an internal fixation device consisting of anatomically contoured titanium plates and associated locking screws, designed for use in small bone reconstruction, corrective osteotomies, and fracture fixation. The system functions by engaging locking screws into threaded plate holes, forming a fixed-angle construct that stabilizes bone fragments, maintains alignment, and promotes healing under rigid fixation principles. All components are manufactured from Ti-6Al-4V ELI alloy (ASTM F136, ISO 5832-3), a biocompatible material with proven use in orthopedic implants. The system includes 2.4 mm Locking Screws, 2.7 mm Continuous Locking Screws, Spear Locking Plates, and Spear Locking Plates II. These implants are CNC-machined, surface-finished, and laser-marked, followed by validated cleaning and packaging. Supplied non-sterile and intended for single use, the devices are sterilized by healthcare providers using moist heat (ISO 17665). Mechanical testing (ASTM F382, ASTM F543) confirms that the plates and screws provide strength, stability, and fatigue resistance comparable to predicate devices, while biocompatibility has been established under the ISO 10993 series. | | |

2.7mm Continuous Locking Screw
The 2.7mm Continuous Locking Screw is intended for use with the Spear Locking Plate, for fixation and compression at the osteotomy or fracture site. It is suitable for metacarpal and metatarsal corrective osteotomies and fracture stabilization.
Spear Locking Plate
The Spear Locking Plate is intended for use in metacarpal and metatarsal reconstruction, corrective osteotomies, and fracture fixation.
Spear Locking Plate II
The Spear Locking Plate II is intended for metacarpal and metatarsal reconstruction, corrective osteotomies, and fracture fixation.
Indications for Use Comparison 21 CFR 807.92(a)(5)
The APS Spear Locking Plate System has the same indications for use as the predicate devices, which include reconstruction, corrective osteotomies, and fracture fixation in small bones.
Technological Comparison 21 CFR 807.92(a)(6)
The APS Spear Locking Plate System is substantially equivalent to the predicate devices, the Synthes 2.4 mm Titanium Locking Screws (K033975) and the Mini MaxLock Extreme Plating System (K101962), in terms of intended use, materials, and performance characteristics. Both systems are intended for use in small bone reconstruction, corrective osteotomies, and fracture fixation, with similar indications for use. The implants are manufactured from comparable titanium alloy materials. Mechanical testing further supports substantial equivalence. Screws were evaluated in accordance with ASTM F543, demonstrating comparable mechanical strength and insertion/ removal torque to the predicate screws. Plates were evaluated in accordance with relevant test methods, including static maximum force, static bending stiffness, and bending stiffness, confirming equivalent structural integrity and mechanical performance to the predicate plating system.
Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)
Mechanical testing was conducted to support substantial equivalence of the APS Spear Locking Plate System. Bone screw testing was conducted in accordance with ASTM F543. For the plate component, testing referenced ASTM F382, but the final plate assessment used a construct-level test setup that deviated from the ASTM F382 plate-only bending configuration, because the subject device is intended to function in a first metatarsal osteotomy fixation construct rather than as an isolated plate. The construct test used first metatarsal synthetic bone models with a reproduced distal metatarsal osteotomy, with lateral-to-medial displacement-controlled static loading (5 mm/min) and plantar-to-dorsal cyclic loading from 0 to 31 N at 0.5 Hz through 1,000 cycles.
This non-standard construct setup was selected to represent clinically relevant functional loading, and interpretation of results was based on both a literature-supported physiological loading benchmark and comparison to the predicate/comparator device under identical test conditions. The results of nonclinical testing support that the APS Spear Locking Plate System is as safe and effective as the predicate device for its intended use. Clinical data were not necessary to support substantial equivalence.

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.
