Indications for Use
The Master stems are indicated for use in partial or total hip arthroplasty and are intended for press-fit (uncemented) use. When used in total hip arthroplasty, the Master Stems are intended for use with Co-Cr-Mo femoral heads and cemented cups or with Co-Cr-Mo femoral heads and Delta TT Acetabular System. When used in partial hip arthroplasty, the MasterSL stems are intended for use with Lock Bipolar Heads. Hip arthroplasty is intended for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: - non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis and hip dysplasia; - rheumatoid arthritis; - treatment of femoral head and neck fractures; - revisions in cases of good remaining femoral bone stock.
Device Story
MasterSL Femoral Stem is a monolithic, collarless, tapered wedge-shaped implant for press-fit uncemented hip arthroplasty. Device is surgically implanted by orthopedic surgeons in a clinical/hospital setting. Stem features a Ti6Al4V alloy body with a plasma-sprayed titanium alloy coating on the proximal half for osseointegration; distal anterior/posterior surfaces include vertical grooves for rotational stability. Neck features a 12/14 conical taper for coupling with femoral heads (Co-Cr-Mo) and is mirror-polished to minimize abrasion against the acetabular cup. Available in 13 sizes with standard/lateralized versions and varying CCD angles. Device restores hip function and reduces pain by replacing the femoral head/neck. Clinical benefit derived from mechanical stability and articulation within the hip joint.
Clinical Evidence
No clinical data provided. Substantial equivalence demonstrated via bench testing, including fatigue resistance testing per ISO 7206-4 and ISO 7206-6, and characterization of the titanium plasma spray coating.
Indicated for skeletally mature patients requiring partial or total hip arthroplasty for non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis, hip dysplasia), rheumatoid arthritis, femoral head/neck fractures, or revisions with good remaining femoral bone stock.
Regulatory Classification
Identification
A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.

#### Description:
The Master femoral stem is a monolithic, collarless, tapered wedge shaped stem intended for press-fit uncemented partial or total hip arthroplasty. When used in total hip arthroplasty the stem is coupled to a Limacorporate Femoral Heads (K112158) and used with either a Limacorporate Cemented Cups (K112158) or Limacorporate Delta TT Acetabular System cup (K112898). When used in partial hip arthroplasty the Master" femoral stem is coupled to a Limacorporate Femoral Heads (K112158) and used with a Lock Bipolar Head (Limacorporate K112158).
The Master" femoral stem is made of Ti6A14V alloy conforming to ASTM F1472 - ISO 5832-3; the proximnal 1/2 of the stem a plasma sprayed coating of titanium alloy (ASTM F1472 - ISO 5832-3). The stem has a tapered rectangular section and the distal anterior and posterior surfaces have a vertical groove for rotational stability. The stem provides a
{1}------------------------------------------------
neck with a 12/14 conical taper to couple to Limacorporate Femoral Heads and the necks are mirror-polished and lowered to reduce accidental abrasion and contact between the stem neck and the acetabular cup. The Master stems is available 13 sizes in both standard and lateralized versions with different CCD angles.
#### Intended Use:
The Master stems are indicated for use in partial or total hip arthroplasty and are intended for press-fit (uncemented) use. When used in total hip arthroplasty, the MasterSL Stems are intended for use with Co-Cr-Mo femoral heads and cemented cups or with Co-Cr-Mo femoral heads and Delta TT Acetabular System. When used in partial hip arthroplasty, the MasterSL stems are intended for use with Lock Bipolar Heads.
Hip arthroplasty is intended for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:
- · non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis and hip dysplasia;
- · rheumatoid arthritis;
- · treatment of femoral head and neck fractures;
- · revisions in cases of good remaining femoral bone stock.
#### Predicate Devices:
- . H-MAX S stems (Limacorporate, K112091):
- . Encore Linear Hip (DJO, K972791 and K991325);
- Modulus Femoral Hip System (Limacorporate, K112158); .
- Taperloc 12/14 Taper Femoral Component (BIOMET, K043537). .
#### Comparable Features to Predicate Device(s):
The Master stems are substantially equivalent to the predicate devices in terms of intended use, indications for use, design and materials. As for all of the predicates, the Master stems is intended for use in total hip arthroplasty and like the Modulus Femoral Hip System predicate (K112158), it can also be used in partial hip arthroplasty. Like all of the predicates, the subject MasterSL stem is intended for press-fit cementless use.
The Master" stems are manufactured from the same materials as the predicate devices. The Master Stem has a tapered wedge design which is similar to all of the predicates exception that predicate Modulus stem is a 2-piece stem with the components coupled through a conical taper while the other predicates and the subject device are all one pice monolithic stems. Like all of the predicates, the subject device is available in standard and lateralized versions, with different CCD angles, offsets and sizes.
### Non-Clinical Testing:
The Master stems were tested in worst case configurations for fatigue resistance according to ISO 7206-4 and ISO 7206-6.
{2}------------------------------------------------
The ROM of the Master 5- hip stem was analyzed using the worst case construct.
The Titanium Plasma Spray coating was characterized to verify the conformity to FDA guideline and referenced standards.
### Clinical Testing:
Clinical testing was not necessary to demonstrate substantial equivalence of the Master St Femoral Stem to the predicate devices. -

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.
