Indications for Use
When used as a posterior pedicle screw fixation system, the Synthes Universal Spinal Hook, Rod and Pedicle/Sacral Screw Fixation System is intended for patients with severe spondylolisthesis (Grades 3 and 4) of the fifth lumbar-first sacral (L5-S1) vertebral joint; who are receiving fusions using autogenous bone graft only; who are having the device fixed or attached to the lumbar and sacral spine; and who are having the device removed after the development of a solid fusion mass. When used as a posterior, non-pedicle screw fixation system, the Universal Spinal Hook, Rod and Pedicle/Sacral Screw Fixation System is also intended for scoliotic, or kyphotic deformities (such as scoliosis, Schevermann's disease); degenerative disk disease (back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), and fractures of the posterior thoracolumbar spine (levels 74-S2). In addition, when using the parallel rod connector, the USS can be connected to the Posterior Cervical/Thoracic Hook/Rod System. The overall levels of fixation are T4-S2.
Device Story
Spinal fixation system comprising rods, hooks, clamps, screws, and parallel rod connector; used for posterior stabilization of thoracolumbar spine (T4-S2). System components implanted by surgeons during spinal fusion procedures to provide mechanical support; parallel rod connector enables 3.5mm to 6mm rod-to-rod connection with Posterior Cervical/Thoracic Hook/Rod System. Device provides rigid fixation to facilitate fusion; intended for removal after solid fusion mass development. Benefits include stabilization of spinal deformities, fractures, and degenerative conditions. System is non-sterile; requires moist heat sterilization.
Clinical Evidence
Bench testing only. Static and fatigue performance characteristics evaluated per ASTM F1717 to demonstrate satisfaction of upper thoracic (T1-T8) fixation requirements.
Indicated for patients with severe spondylolisthesis (Grades 3-4) at L5-S1 requiring fusion with autogenous bone graft; scoliotic or kyphotic deformities (e.g., scoliosis, Scheuermann's disease); degenerative disc disease; and fractures of the posterior thoracolumbar spine (T4-S2). Contraindicated for pedicle screw fixation above L5-S1.
Regulatory Classification
Identification
A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.

Device: SYNTHES Spine Universal Spinal Hook, Rod, Pedicle/Sacral Screw Fixation System compared to the Liberty Posterior Spinal System (K964254) and the Titanium Spinal Rod System (K970635).
The Synthes Universal Spinal Hook, Rod, Pedicle/Sacral Screw Fixation System currently consists of rods, hooks, clamps and screws. These components were previously cleared in K951626, K951794, K962608, K963045, K963357, and K964416. This 510(k) submission is extending the region of the posterior spine in which the USS hook and rods may be used (i.e., from T8-S2 to T4-S2). In addition to these components Synthes is adding a new parallel rod connector. The connector is intended to allow a rod (3.5mm) to rod (6mm) connection with the Posterior Cervical/Thoracic Hook/Rod System. The Universal Spinal Hook, Rod, Pedicle/Sacral Screw Fixation System is indicated for the following:
When used as a posterior pedicle screw fixation system, the Synthes Universal Spinal Hook, Rod and Pedicle/Sacral Screw Fixation System is intended for patients with severe spondvlolisthesis (Grades 3 and 4) of the fifth lumbar-first sacral (LS-S1) vertebral joint; who are receiving fusions using autogenous bone graft only; who are having the device fixed or attached to the lumbar and sacral spine; and who are having the device removed after the development of a solid fusion mass.
When used as a posterior, non-pedicle screw fixation system, the Universal Spinal Hook, Rod and Pedicle/Sacral Screw Fixation System is also intended for scoliotic, or kyphotic deformities (such as scoliosis, Schevermann's disease); degenerative disk disease (back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), and fractures of the posterior thoracolumbar spine (levels 74-S2). In addition, when using the parallel rod connector, the USS can be connected to the Posterior Cervical/Thoracic Hook/Rod System.
The overall levels of fixation are T4-S2.
Manual surgical instruments that will be marketed with this system will be the same as that currently marketed with the Universal Splual Hook, Rod, Pedicle/Sacral Serew Fixation System (USS).
Mechanical testing was performed in accordance with ASTM standard F1717. This testing documented both static and fatigue performance characteristics of the USS system, when connected via the parallel roo connector, to the Posterior Cervical Thoracic Hook System. This testing clearly demonstrated that the performance characteristics satisfy the requirements of upper thoracic (T1-T8) fixation.
Material composition of the parallel rod connector is TiAlNb (ASTM F1295) and is identical to numerous other Synthes Spinal products that have been cleared via the 510(k) process. The remaining components of the USS system are composed of the same materials described within their respective 510(k)s. The surgical technique and instrumentation to implant this system is the same as that of the Synthes USS.
This system is provided non-sterile; moist heat sterilization is recommended,
{1}------------------------------------------------
Based on the above, the SYNTHES Spine Universal Spinal Hook, Rod, Pedicle/Sacral Screw Fixation System is substantially equivalent to the Liberty Posterior Spinal System (K964254) and the Titanium Spinal Rod System (K970635).

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.
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.
