Regulatory Classification
Identification
A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.

#### Device Description:
The Signature Orthopaedics' Pinehurst Anterior Cervical Plate System's components are manufactured from Ti6Al4V alloy per ISO 5832-3 and ASTM-F136.
The Pinehurst Anterior Cervical Plate Systemis temporary supplemental fixation device consisting of variety of shapes and sizes of plates and screws. The plates attach to the anterior cervical spine with a minimum four screw per plate. The plates are offered in
{4}------------------------------------------------
one-level, two-level, three-level and four-level fusion configurations. The plates have an integrated locking mechanism that prevents screw-backout. The Pinehurst plates and screws are supplied sterile.
### Indications for Use:
The Signature Orthopaedics Pinehurst Anterior Cervical Plate System is intended for anterior screw fixation to the cervical spine (C2-C7). The System is indicated for use in the immobilisation and stabilisation of the spine as an adjunct to fusions in patients with:
- Degenerative disc disease (as defined by neck pain of discogenic origin with . degeneration of the disc confirmed by patient history and radiographic studies);
- . Spondylolisthesis;
- Trauma (I.e fracture or dislocations); ●
- . Tumors:
- . Deformity (defined as kyphosis, lordosis, or scoliosis);
- Pseudoarthrosis;
- Failed previous fusion;
- Spinal stenosis
#### Performance Testing:
Non-clinical testing and engineering evaluations were conducted to verify that the performance of Pinehurst Anterior Cervical Plate System is adequate for anticipated invivo use. The following non-clinical testings were carried out on the worst case sizes of the plates and screws:
- . Static and dynamic compression bending testing
- . Static torsion testing
- Screw insertion testing ●
- . Screw pull-out testing
- . Screw torque to failure testing
#### Substantial Equivalence:
That Signature Orthopaedics' Pinehurst Anterior Cervical Plate System have the same intended use, indication for use, materials and similar design features as the Spinal Concepts SC-AccFix Thinline Anterior Cervical Plate System (K013979), L&K Biomed LnK Anterior Cervical Plate System (K143279), Orthofix CETRA Anterior Cervical Plate System (K162638), Globus Medical PROVIDENCE Anterior Cervical Plate System (K070775), Synthes CSLP System (K945700, K000536, K000742, K030866) and Signature Orthopaedic NOOSA Anterior Lumbar Plate System (K163625). Nonclinical testing results support the substantial equivalence claim.
#### Comparison of technological characteristics
Temporary immobilisation and stabilisation of spinal segments as supplemental fixation in spinal fusion procedure is the technological principle for both the subject device and the predicate devices. The subject and predicate devices are based on the following same technological elements:
- . The indication for use of the subject device is the same as the predicate devices
{5}------------------------------------------------
- . The intended surgery sites of the subject device is the same as intended surgery sites of the predicates
- . The subject device is manufactured from the same material as the predicate devices
- . The locking mechanism of the subject device is equivalent to the locking mechanism of LnK and CETRA plate systems
- . The profile thickness of the subject device are within the profile thickness of the predicates
- The size range of the subject devices fall within the size range of the predicates
- . The subject device accommodate the same number of supplemental as the predicate devices
- . Both subject device and predicates are contoured to match the vertebral body
- . Both subject device and predicates are implanted manually and the screws are hand tightened
The following technological differences exist between the subject and predicate devices:
- Some of the design features are different between the subject and predicate devices
- . The material used on one of the predicates are slightly different than the subject device
- The material used for two of the predicate devices are slightly different than the subject device (Ti6Al4V ELI vs Ti6Al4V)
- . The screw locking mechanism on two of the predicates are different the subject device
## Conclusions:
Technical comparison of the subject and predicate devices demonstrates equivalence in device design, intended use, indications for use and material. Non-clinical data raises no new safety or effectiveness questions of the Pinehurst Anterior Cervical Plate System.

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.
