Indications for Use
The SMR Anatomic Shoulder System is indicated for partial or total, primary or revision shoulder joint replacement in patients suffering from disability due to: - Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis: - Inflammatory degenerative joint disease such as rheumatoid arthritis: - Treatment of acute fractures of the humeral head that cannot be treated with other fracture fixation methods: - Revision of a failed primary implant; - Cuff tear arthropathy (CTA Heads only). The Large Resection Stems (not available in the US) are indicated for oncology applications. The SMR Reverse Shoulder System is indicated for primary, fracture or revision total shoulder replacement in a grossly rotator cuff deficient joint with severe arthropathy (disabled shoulder). The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.
Device Story
SMR 3-Pegs Glenoids are UHMWPE prosthetic components for cemented fixation in total shoulder replacement. Device features spherical backside with three pegs to enhance cement adhesion; articulating surface radius exceeds humeral head radius to allow superior/inferior and anterior/posterior translation. Used in clinical settings by orthopedic surgeons during shoulder arthroplasty. Provides stable glenoid articulation; restores joint function; reduces pain associated with degenerative or inflammatory joint disease. Sterile, single-use device.
Clinical Evidence
Bench testing only. Mechanical evaluation performed per ASTM F1829 (static shear) and ASTM F2028 (dynamic loosening/disassociation). Range of motion simulation conducted. No clinical data required for substantial equivalence.
Indicated for patients requiring partial, total, primary, or revision shoulder joint replacement due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), inflammatory degenerative joint disease (rheumatoid arthritis), acute humeral head fractures, failed primary implants, or cuff tear arthropathy. Reverse system indicated for grossly rotator cuff deficient joints with severe arthropathy; requires functional deltoid muscle and suitable anatomy.
Regulatory Classification
Identification
A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).

#### Description:
The SMR 3-Pegs Glenoids are made from standard UHMWPE ). They are intended for cemented fixation only.
The SMR 3-Pegs Glenoids are available in two sizes (Small and Standard). They are characterized by an articulating surface with a radius of curvature greater than the corresponding humeral head. This mismatch allows for translation of the head in the superior/inferior and anterior/posterior directions. The back surface of the component is spherical in geometry and has three pegs for fixation in the glenoid.
The SMR 3-Pegs Glenoids are designed to articulate with the Limacorporate SMR humeral heads indicated for use in total shoulder replacement.
#### Intended Use:
The SMR Anatomic Shoulder System is indicated for partial or total, primary or revision shoulder joint replacement in patients suffering from disability due to:
- Non-inflammatory degenerative joint disease including osteoarthritis and avascular . necrosis:
- Inflammatory degenerative joint disease such as rheumatoid arthritis; .
- Treatment of acute fractures of the humeral head that cannot be treated with other . fracture fixation methods:
- Revision of a failed primary implant; .
- Cuff tear arthropathy (CTA Heads only).
The Large Resection Stems (not available in the US) are indicated for oncology applications.
The SMR Reverse Shoulder System is indicated for primary, fracture or revision total shoulder replacement in a grossly rotator cuff deficient joint with severe arthropathy

(disabled shoulder). The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.
The Modular SMR Shoulder System allows the assembly of components in various humeral and glenoid constructs. The constructs are intended for cemented and uncemented use as specified in the following table.
In the Anatomic shoulder the humeral construct consists of the humeral stem, the humeral body, the adaptor taper and the humeral head. In the Reverse shoulder the humeral construct consists of the humeral stem, the reverse humeral body and the reverse liner. On the humeral side the fixation of the humeral stem determines if the construct is cemented or uncemented.
The Anatomic glenoid construct consists of an all polyethylene glenoid or a metal back assembled with a liner while the Reverse glenoid construct consists of the metal back, the connector and the glenosphere. On the glenoid side, the fixation of the all polyethylene glenoid or the metal back determines if the construct is cemented or uncemented.

#### *NOTE :
- . In the US, the SMR Metal Glenoid/Liner construct, used as part of the SMR Anatomic Shoulder Replacement, is intended for use with bone cement and should be used without bone screws.
- . Outside the US, the SMR Metal Backed Glenoid/Liner construct, used as part of the SMR Anatomic Shoulder Replacement, is intended for uncemented use with the addition of screws for fixation.
- The SMR Metal Backed Glenoid/Connector/Glenosphere construct, used as part of the SMR . Reverse Shoulder replacement, is intended for uncemented use with the addition of screws for fixation.
#### Predicate Devices:
- Limacorporate SMR Cemented Glenoids included in the following cleared 510(k): .
- SMR Cemented Shoulder System (K100858); ।
- . SMR Uncemented Shoulder System (K101263);
- SMR CTA Humeral Heads (K110847); -
- SMR Revision Stems (K111212). -
- . Global Shoulder Crosslink Glenoid (DePuy, K052472);
- Glenoid Component for the Foundation Total Shoulder System (Encore DJO, . K960906).
#### Comparable Features to Predicate Device(s):
The intended use and indications for the Limacorporate SMR 3-Pegs Glenoids are similar to those of the referenced predicate devices and identical to those of the SMR cemented glenoids (K100858, K101263, K110847 - "rotator cuff tear arthropathy" and K I 1212 - "revision of a failed primary component"). As for all the referenced predicate devices where a glenoid component is used, the SMR 3-Pegs glenoids are used in total shoulder replacements and are intended for use with bone cement only.
The surface of the SMR 3-Pegs Glenoids articulating with the humeral heads and the spherical backside surface are identical to those of the already cleared SMR glenoids. As for all the referenced predicate devices, the SMR 3-Pegs glenoids have a radius of curvature greater than the radius of the articulating humeral heads. The three pegs used for the fixation by means of bone cement are very similar to those of Foundation Total Shoulder glenoid (Encore - DJO) and to the peripheral pegs of the Global Shoulder Crosslink glenoid (DePuv). The presence of grooves on the fixation peg has the same functionality (enhance cement adhesion) for SMR 3-Pegs Glenoids as for the other cemented glenoids of Limacorporate and for the Foundation Total Shoulder glenoid (Encore - DJO).
The UHMWPE used for the SMR 3-Pegs Glenoids is the same material used for the SMR System cemented glenoids (Limacorporate). The two sizes of glenoids available for the SMR 3-Pegs Glenoids have the same identical dimensions of the sizes Small and Standard of the cleared SMR cemented glenoids.

Section 5 - Page 3 of 4
{3}------------------------------------------------
All SMR 3-Pegs Glenoids and referenced Predicate Devices are sterile, single use devices. Sterilization of the SMR 3-Pegs Glenoids performed by means of ethylene oxide (EtO), the Sterility Assurance Level (SAL of 100), the shelf life of 5 years are identical to that of the cleared cemented glenoids of the SMR Systems.
#### Non-Clinical Testing:
The SMR 3-Pegs Glenoid has undergone mechanical tests according to ASTM F1829 (Standard Test Method for Static Evaluation of Glenoid Locking Mechanism in Shear) and ASTM F2028 (Standard Test Methods for Dynamic Evaluation of Glenoid Loosening or Disassociation). A Range of Motion simulation has been performed to ensure the device design does not overly limit range of motion. All mechanical testing was done on worst case components or constructs. Where possible, standard test methods were used to allow comparison to testing of the predicate devices. The testing results demonstrated the device's ability to perform under expected clinical conditions.
#### Clinical Testing:
Clinical testing was not necessary to demonstrate substantial equivalence of the SMR 3-Pegs Glenoids to the predicate device(s).

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.
